This page documents the user model.

Data Shape 

Gadget's database stores user records by storing and retrieving each of the fields defined on the model in the Gadget Editor to a managed database. Gadget has generated a GraphQL type matching the configured fields for user:

You can preview what a real record's shape looks like by fetching it using the  example-app API Playground.

Any fetched user record will have this same User type, and expose the same data by default, regardless of if it's fetched by ID or as part of a findMany. This means you can select any of the record's fields wherever you like in a GraphQL query according to the use case at hand.

Retrieving one user record 

Individual user records can be retrieved using the "find by ID" API endpoint. You can also return only some fields, or extra fields beyond what Gadget retrieves by default, using the select option.

The findOne function throws an error if no matching record is found, which you will need to catch and handle. Alternatively, you can use the maybeFindOne function, which returns null if no record is found, without throwing an error.

Similarly, the useFindOne React hook returns (but does not throw) an error when no matching record is found, while the useMaybeFindOne hook simply returns null if no record is found, without also returning an error.

Get one user
const userRecord = await api.user.findOne("123");
console.log(userRecord.id); //=> a string
console.log(userRecord.createdAt); //=> a Date object
1const FindOneComponent = (props) => {
2 const [{ data, error, fetching }, refresh] = useFindOne(api.user, "123");
3
4 console.log(data?.id); //=> a string
5 console.log(data?.createdAt); //=> a Date object
6
7 return <>{JSON.stringify(data)}</>;
8};
1query GetOneUser($id: GadgetID!) {
2 user(id: $id) {
3 __typename
4 id
5 state
6 createdAt
7 email
8 roles {
9 key
10 name
11 }
12 updatedAt
13 }
14}
Variables
json
{ "id": "123" }

Retrieving the first of many user records 

The first record from a list of records can be retrieved using the "find first" API endpoint. The source list of records can be filtered using the filter option, sorted using the sort option, searched using the search option, though no pagination options are available on this endpoint. You can also return only some fields, or extra fields beyond what Gadget retrieves by default using the select option.

The findFirst function throws an error if no matching record is found, which you will need to catch and handle. Alternatively, you can use the maybeFindFirst function, which returns null if no record is found, without throwing an error.

Similarly, the useFindFirst React hook returns (but does not throw) an error when no matching record is found, while the useMaybeFindFirst hook simply returns null if no record is found, without also returning an error.

Get first user
const userRecord = await api.user.findFirst();
console.log(userRecord.id); //=> a string
console.log(userRecord.createdAt); //=> a Date object
1const FindFirstComponent = (props) => {
2 const [{ data, error, fetching }, refresh] = useFindFirst(api.user);
3
4 console.log(data?.id); //=> a string
5 console.log(data?.createdAt); //=> a Date object
6
7 return <>{JSON.stringify(data)}</>;
8};

Retrieving many user records 

Pages of user records can be retrieved by using the "find many" API endpoint. The returned records can be filtered using the filter option, sorted using the sort option, searched using the search option, and paginated using standard Relay-style pagination options. You can also return only some fields, or extra fields beyond what Gadget retrieves by default using the select option.

This GraphQL endpoint returns records in the Relay Connection style (as a list of edges with nodes and cursors) so they can be paginated. The users GraphQL endpoint works with any Relay-compatible caching client, or you can use Gadget's JS client for pagination with the findMany function.

Find a page of users 

Fetch a page of records with the user.findMany JS method or the users GraphQL field. No options are required. The records returned will be implicitly sorted by ID ascending.

Find many users
const userRecords = await api.user.findMany();
console.log(userRecords.length); //=> a number
console.log(userRecords[0].id); //=> a string
1const FindManyComponent = (props) => {
2 const [{ data, error, fetching }, refresh] = useFindMany(api.user);
3 if (!data) return null;
4
5 console.log(data.length); //=> a number
6
7 return <>{data.map((record) => JSON.stringify(record))}</>;
8};
1query FindManyUsers {
2 users {
3 edges {
4 node {
5 __typename
6 id
7 state
8
9 # ...
10
11 createdAt
12 updatedAt
13 }
14 }
15 }
16}
Variables
json
{}

Your app's API is built using GraphQL, which makes it easy to retrieve data from related records through fields like belongs to and has many.

To optimize the performance of your API, data from related records is not retrieved by default, but you can change what data is retrieved with the `select` option to API calls.

For example, you can fetch has many data from the records linked by the sessions field using the select option:

Get related data from sessions
1const userRecord = await api.user.findFirst({
2 select: {
3 id: true,
4 sessions: {
5 edges: {
6 node: {
7 id: true,
8 createdAt: true,
9 },
10 },
11 },
12 },
13});
14console.log(userRecord.sessions?.map((edge) => edge.node.id)); //=> the related records' ids
1const FindRelatedComponent = (props) => {
2 const [{ data, error, fetching }, refresh] = useFindFirst(api.user, {
3 select: {
4 id: true,
5 sessions: {
6 edges: {
7 node: {
8 id: true,
9 createdAt: true,
10 },
11 },
12 },
13 },
14 });
15 if (!data) return null;
16 // show the related records ids
17 return <>{data.sessions?.map((edge) => edge.node.id)}</>;
18};

When using an explicit select option, be sure to include any fields you need from all models in your query, including the parent model. The default selection no longer applies when you pass select.

Retrieving a single user record by a uniquely identifiable field 

After adding a unique validation to a field, you can retrieve a single record by using the finders generated below. If you would like to edit the fields returned or filtering, see the filtering section.

Retrieving a single user record by id 

Individual user records can be retrieved using the "find many" API endpoint pre-filtered by the field's id. Throws if stored data is not unique.

Find users
const userRecord = await api.user.findById("some-value");
console.log(userRecord.id); //=> a string
1const FindByComponent = (props) => {
2 const [{ data, error, fetching }, refresh] = useFindBy(
3 api.user.findById,
4 "some-value"
5 );
6
7 console.log(data?.id); //=> a string
8
9 return <>{JSON.stringify(data)}</>;
10};

Retrieving a single user record by email 

Individual user records can be retrieved using the "find many" API endpoint pre-filtered by the field's email. Throws if stored data is not unique.

Find users
const userRecord = await api.user.findByEmail("some-value");
console.log(userRecord.id); //=> a string
1const FindByComponent = (props) => {
2 const [{ data, error, fetching }, refresh] = useFindBy(
3 api.user.findByEmail,
4 "some-value"
5 );
6
7 console.log(data?.id); //=> a string
8
9 return <>{JSON.stringify(data)}</>;
10};

Sorting 

Records can be sorted in the database to retrieve them in a certain order. Records are always implicitly sorted by ID ascending unless an explicit sort on the id field is defined. The GraphQL type UserSort defines which fields can be sorted by.

Records can be sorted by multiple different fields and in multiple different directions by passing a list of UserSort instead of just one.

Pass the sort option to the JS client, or the sort variable to a GraphQL query to sort the records returned.

Sort user by most recently created
const userRecords = await api.user.findMany({ sort: { createdAt: "Descending" } });
const [result, refresh] = useFindMany(api.user, {
sort: { createdAt: "Descending" },
});
const { data, error, fetching } = result;
1query FindManyUsers($sort: [UserSort!]) {
2 users(sort: $sort) {
3 edges {
4 node {
5 __typename
6 id
7 state
8
9 # ...
10
11 createdAt
12 updatedAt
13 }
14 }
15 }
16}
Variables
json
{ "sort": { "createdAt": "Descending" } }

Sort by multiple fields by passing an array of { [field]: "Ascending" | "Descending" } objects.

Sort user by multiple fields
const userRecords = await api.user.findMany({
sort: [{ id: "Descending" }, { createdAt: "Ascending" }],
});
const [result, refresh] = useFindMany(api.user, {
sort: [{ id: "Descending" }, { createdAt: "Ascending" }],
});
const { data, error, fetching } = result;
1query FindManyUsers($sort: [UserSort!]) {
2 users(sort: $sort) {
3 edges {
4 node {
5 __typename

11 createdAt
12 updatedAt
13 }
14 }
15 }
16}
Variables
json
{ "sort": [{ "id": "Descending" }, { "createdAt": "Ascending" }] }

Available fields for sorting 

You can sort user records by the following fields:

FieldSort type
idAscending / Descending
emailAscending / Descending
stateAscending / Descending
createdAtAscending / Descending
updatedAtAscending / Descending

For example, you can sort by the id field:

Sort users by id descending
const userRecords = await api.user.findMany({
sort: { id: "Descending" },
});
const [result, refresh] = useFindMany(api.user, {
sort: { id: "Descending" },
});
const { data, error, fetching } = result;
1query FindManyUsers($sort: [UserSort!]) {
2 users(sort: $sort) {
3 edges {
4 node {
5 __typename
6 id

12 updatedAt
13 }
14 }
15 }
16}
Variables
json
{ "sort": { "id": "Descending" } }

Read more about sorting in the Sorting and Filtering reference.

Searching 

user records can be searched using Gadget's built in full text search functionality. Gadget search is appropriate for powering autocompletes, searchable tables, or other experiences where humans are writing search queries. It's typo tolerant, synonym aware and supports simple search operators like ! to exclude search terms.

Search Users by passing the search parameter with a search query string.

Search isn't field specific in Gadget -- all String or RichText field types are searched with the built in search functionality.

Full text search Users
const userRecords = await api.user.findMany({
search: "a specific phrase to search for",
});
const [result, refresh] = useFindMany(api.user, {
search: "a specific phrase to search for",
});
const { data, error, fetching } = result;
1query FindManyUsers($search: String) {
2 users(search: $search) {
3 edges {
4 node {
5 __typename
6 id
7 state

9 # ...
10
11 createdAt
12 updatedAt
13 }
14 }
15 }
16}
Variables
json
{ "search": "a specific phrase to search for" }

Filtering 

user records can be filtered to return only the appropriate records. Records can be filtered on any field, including those managed by Gadget or fields added by developers. Filters can be combined with sorts, searches and paginated using cursor-based Relay pagination.

Filter Users by passing the filter parameter with a filter object. Filter objects are nestable boolean conditions expressed as JS objects capturing a key, an operator, and usually a value.

Find Users created in the last day
const yesterday = new Date(Date.now() - 864e5);
const userRecords = await api.user.findMany({
filter: { createdAt: { greaterThan: yesterday } },
});
const yesterday = new Date(Date.now() - 864e5);
const [result, refresh] = useFindMany(api.user, {
filter: { createdAt: { greaterThan: yesterday } },
});
const { data, error, fetching } = result;
1query FindManyUsers($filter: [UserFilter!]) {
2 users(filter: $filter) {
3 edges {
4 node {
5 __typename
6 id
7 state
8
9 # ...

15 }
16}
Variables
json
{ "filter": { "createdAt": { "greaterThan": "2024-05-03T11:49:13.276Z" } } }

Available fields for filtering 

The GraphQL type UserFilter defines which fields can be filtered on.

Field

Filter type

idIDFilter
emailEmailFilter
stateRecordStateFilter
rolesRoleAssignmentsFilter
createdAtDateTimeFilter
updatedAtDateTimeFilter

For example, we can filter user records on the id field:

const userRecords = await api.user.findMany({
filter: {
id: { isSet: true },
},
});
1const [result, refresh] = useFindMany(api.user, {
2 filter: {
3 id: { isSet: true },
4 },
5});
6const { data, error, fetching } = result;
1query FindManyUsers($filter: [UserFilter!]) {
2 users(filter: $filter) {
3 edges {
4 node {
5 __typename
6 id

13 }
14 }
15 }
16}
Variables
json
{ "filter": { "id": { "isSet": true } } }

Read more about the available filters in the Sorting and Filtering reference.

Combining filters 

Records can be filtered by multiple different fields simultaneously. If you want to combine filters using boolean logic, nest them under the AND, OR, or NOT keys of a parent filter. Filters can be nested deeply by passing multiple levels boolean condition filters.

You can also pass a list of filters to the filter parameter which will be implicitly ANDed with one another such that they all need to match for a record to be returned.

Users created this week or updated today
1const yesterday = new Date(Date.now() - 86400000);
2const oneWeekAgo = new Date(Date.now() - 604800000);
3const userRecords = await api.user.findMany({

Pagination 

All Gadget record lists, including the top level user finder as well as associations to user, are structured as GraphQL connections. GraphQL connections are the de facto standard for querying lists and support cursor-based forward and backward pagination. When querying via GraphQL, you must select the edges field and then the node field to get the user record. When querying using a Gadget API client, the GraphQL queries are generated for you and the records are unwrapped and returned as a GadgetRecordList ready for use.

user pagination supports the standard GraphQL connection pagination arguments: first + after, or last + before. Pagination is done using cursors, which you can retrieve from the edge.cursor field or the pageInfo.startCursor properties.

Get the first page of 25 users
const userRecords = await api.user.findMany({ first: 25 });
console.log(userRecords.length); //=> no greater than 25
1const FirstPage = (props) => {

Pagination Limits 

Root-level record finders like users support a maximum page size of 250 records and a default page size of 50 records. The page size is controlled using the first or last GraphQL field arguments.

Related record finders that access lists of records through a has many or has many through field support a maximum page size of 100 records and a default page size of 50 records.

Get the next or previous page 

When using the generated JavaScript API client, including the api parameter in a Gadget code effect, the record lists returned from findMany calls can be paginated using the nextPage() or previousPage() option.

Both nextPage() and previousPage() will throw an error if the corresponding hasNextPage or hasPreviousPage is false.

JavaScript
1const userRecords = await api.user.findMany();
2if (userRecords.hasNextPage) {
3 const nextPage = await userRecords.nextPage();
4}
5if (userRecords.hasPreviousPage) {
6 const prevPage = await userRecords.previousPage();
7}

When using React and paging through records, you can use cursors to get the previous or next pages of records. This is an example of a React component that pages forward and backward through 2 records at a time for user.

React
1import { api } from "../api"; // your Gadget project's API Client
2import { useFindMany } from "@gadgetinc/react";
3import { useCallback, useState } from "react";
4
5export default function TestComponent() {
6 const NUM_ON_PAGE = 2; // the number of records per page
7
8 const [cursor, setCursor] = useState({ first: NUM_ON_PAGE });
9 // using Gadget React hooks to fetch records of user
10 const [{ data, fetching, error }] = useFindMany(api.user, {
11 ...cursor,
12 });
13
14 const getNextPage = useCallback(() => {
15 // use first + after to page forwards
16 setCursor({ first: NUM_ON_PAGE, after: data.endCursor });
17 }, [data]);
18
19 const getPreviousPage = useCallback(() => {
20 // use last + before to page backwards
21 setCursor({ last: NUM_ON_PAGE, before: data.startCursor });
22 }, [data]);
23
24 return (
25 <div>
26 <button onClick={getPreviousPage} disabled={!data?.hasPreviousPage}>
27 Previous page
28 </button>
29 <button onClick={getNextPage} disabled={!data?.hasNextPage}>
30 Next page
31 </button>
32 {!fetching && data.map((d) => <div>{d.id}</div>)}
33 </div>
34 );
35}

Get all records 

If you need to get all available data for user, you will need to paginate through all pages of data. If you have a large amount of data, this can take a long time. Make sure you need to collect all data at once before writing a pagination loop that reads all records! If you are querying records for display in a UI and cannot display all your records at once, we don't recommend fetching all the data beforehand - instead, use the cursor to read additional data when the user needs it.

If you need all data for analytics applications or to collect some statistics on your data, consider options like intermediate models and pre-defined data rollups.

If you have determined that you need all your data, you can fetch it using cursors and a loop. We also suggest using select so that you only grab fields that are needed, in addition to applying a filter, if possible. Using first with the maximum allowable value will also allow you to grab the maximum number of records you can at once.

Page through all records
JavaScript
1const allRecords = []; // use allRecords to store all records
2let records = await api.user.findMany({
3 first: 250,
4 select: {
5 id: true,
6 },
7 filter: {
8 // add filter conditions, if possible
9 },
10});
11
12allRecords.push(...records);
13
14// loop through additional pages to get all protected orders
15while (records.hasNextPage) {
16 // paginate
17 records = await records.nextPage();
18 allRecords.push(...records);

When using the JavaScript client, all of findOne, maybeFindOne, findMany, findFirst, maybeFindFirst, and various action functions, allow requesting specific fields of a user and its relationships. The select option controls which fields are selected in the generated GraphQL query sent to the Gadget API. Pass each field you want to select in an object, with true as the value for scalar fields, and a nested object of the same shape for nested fields.

Gadget has a default selection that will retrieve all of the scalar fields for a user. If you don't pass a select option to a record finder, this default selection will be used.

Select only some user fields
1// fetch only the id and createdAt field
2const userRecords = await api.user.findMany({
3 select: { id: true, createdAt: true },
4});
5// fetch all the scalar fields for the model, but no relationship fields
6const userRecords = await api.user.findMany();
1const SelectionComponent = (props) => {
2 // fetch only the id and createdAt field
3 const [{ data, error, fetching }, refresh] = useFindMany(api.user, {
4 select: { id: true, createdAt: true },
5 });
6 // ...
7};

Realtime query results 

When using the React hooks, you can subscribe to realtime updates to the results of a query. This is useful for updating your UI when a record is created, updated, or deleted by anyone using your app.

For example, you can render a list of the first ten user records, which will automatically update when backend data changes:

Relatime record results
JavaScript
1export const FirstPage = (props) => {
2 const [{ data, error, fetching }] = useFindMany(api.user, {
3 // make this a realtime live query
4 live: true,
5 first: 10,
6 });
7 if (!data) return null;
8 return (
9 <div>
10 {data.map((record) => (
11 <div key={record.id}>{record.id}</div>
12 ))}
13 </div>
14 );
15};

For more information, see the Realtime Queries guide.

Type Safety 

The select option is fully type safe if you're using TypeScript. The returned GadgetRecord type will have a <Shape> exactly matching the fields and nested fields you selected.

This behavior of selecting only some fields is built right into GraphQL. If you want to limit or expand what you retrieve from a GraphQL query, include or exclude those fields in your GraphQL query. For more information on executing GraphQL queries, see GraphQL.

Select nested user fields
1// fetch the id and createdAt field, and fetch some nested fields from an example relationship field named `someRelatedObject`
2const userRecords = await api.user.findMany({
3 select: {
4 id: true,
5 createdAt: true,
6 someRelatedObject: { id: true, createdAt: true },
7 },
8});
1const SelectionComponent = (props) => {
2 // fetch the id and createdAt field, and fetch some nested fields from an example relationship field named `someRelatedObject`
3 const [{ data, error, fetching }, refresh] = useFindMany(api.user, {
4 select: {
5 id: true,
6 createdAt: true,
7 someRelatedObject: { id: true, createdAt: true },
8 },
9 });
10 // ...
11};

Combining parameters 

Sort, search, filtering, selection, and pagination parameters can be combined to access the exact set of records needed for your use case.

Invoking Actions 

user records are changed by invoking Actions. Actions are the things that "do" stuff -- update records, make API calls, call backend code, etc. Actions with a GraphQL API trigger each have one corresponding GraphQL mutation and a corresponding function available in the API client libraries. Nested Actions can also be invoked with the API client, by providing the actions as input to any relationship fields.

Action Result format 

Each API action returns results in the same format that includes a success indicator, errors, and the actual result if the action succeeded. The result is the record that was acted on for a model action, or a list of records for a bulk action, or a JSON blob for Global Actions. Model actions that delete the record don't return the record.

The success field returns a boolean indicating if the action executed as expected. Any execution errors are returned in the errors object, which will always be null if success is true or contain ExecutionError objects if success is false.

ExecutionError objects always have a message describing what error prevented the action from succeeding, as well as a code attribute that gives a stable, searchable, human-readable error class code for referencing this specific error. Details on each error code can be found in the Errors documentation. All ExecutionError object types returned by the GraphQL object can be one of many types of error, where some types have extra data that is useful for remedying the error. All error types will always have message and code properties, but some, like InvalidRecordError have extra fields for use by clients.

Errors when using the generated client 

The generated JavaScript client automatically interprets errors from invoking actions and throws JavaScript Error instances if the action didn't succeed. The Error objects it throws are rich, and expose extra error properties beyond just message and code if they exist.

Errors thrown by the JavaScript client are easiest to catch by using a try/catch statement around an await, like so:

JavaScript
1import {
2 GadgetOperationError,
3 InvalidRecordError,
4} from "@gadget-client/example-app";
5
6// must be in an async function to use \`await\` syntax
7const runAction = async () => {
8 try {
9 return await api.exampleModel.create({ name: "example record name" });
10 } catch (error) {
11 if (error instanceof GadgetOperationError) {
12 // a recognized general error has occurred, retry the operation or inspect \error.code\`
13 console.error(error);
14 } else if (error instanceof InvalidRecordError) {
15 // the submitted input data for the action was invalid, inspect the invalid fields which \`InvalidRecordError\` exposes
16 console.error(error.validationErrors);
17 } else {
18 // an unrecognized error occurred like an HTTP connection interrupted error or a syntax error. Re-throw it because it's not clear what to do to fix it
19 throw error;
20 }
21 }
22};

For more information on error codes, consult the Errors documentation.

type CreateUserResult {
success: Boolean!
errors: [ExecutionError!]

}

When running actions on the user model, you can set the value of any belongs to or has many relationships in the same API call.

Linking existing child records 

For has many fields, actions on user records can also update child records to link to this record. You can link existing child records by passing a nested action to invoke on the child record. Gadget will implicitly link the referenced child record to the outer parent record in the API call.

Linking to a new child record 

You can also nest actions on child records to create new children when running actions on the parent. Pass a nestedcreate action for the child record, and Gadget will implicitly link it to the outer parent record in your API call.

Bulk Actions 

You can run the same action for an array of inputs all at once with bulk actions. Bulk Actions are executed as a single API call and offer better performance when running the same action on many records.

Creates, updates, deletes, and custom actions can all be run in bulk. Bulk Actions repeat the same action each time across a variety of different records. If you want to call different actions, you can't use Bulk Actions and must instead make multiple API calls.

If a bulk action group fails on some of the individual records, the remaining records will still be processed, and the list of errors will be returned in the result. Only the records which succeed in executing the action will be returned in the result.

Bulk user signUp
