useForm
The @pankod/refine-react-hook-form adapter allows you to integrate the React Hook Form library with refine, enabling you to manage your forms in a headless manner. This adapter supports all of the features of both React Hook Form and refine's useForm hook, and you can use any of the React Hook Form examples as-is by copying and pasting them into your project."
All the data related hooks(useTable, useForm, useList etc.) of refine can be given some common properties like resource, meta etc.
Please refer to General Concepts for more information.
Installation
Install the @pankod/refine-react-hook-form library.
npm i @pankod/refine-react-hook-form
Basic Usage
For more detailed usage examples please refer to the React Hook Form documentation.
We'll show the basic usage of useForm by adding an editing form.
import { useSelect } from '@pankod/refine-core'
import { useForm } from '@pankod/refine-react-hook-form'
export const PostEdit: React.FC = () => {
const {
refineCore: { onFinish, formLoading, queryResult },
register,
handleSubmit,
resetField,
formState: { errors },
} = useForm()
const { options } = useSelect({
resource: 'categories',
defaultValue: queryResult?.data?.data.category.id,
})
useEffect(() => {
resetField('category.id')
}, [options])
return (
<form onSubmit={handleSubmit(onFinish)}>
<label>Title: </label>
<input {...register('title', { required: true })} />
{errors.title && <span>This field is required</span>}
<br />
<label>Status: </label>
<select {...register('status')}>
<option value="published">published</option>
<option value="draft">draft</option>
<option value="rejected">rejected</option>
</select>
<br />
<label>Category: </label>
<select
{...register('category.id', {
required: true,
})}
defaultValue={queryResult?.data?.data.category.id}
>
{options?.map((category) => (
<option key={category.value} value={category.value}>
{category.label}
</option>
))}
</select>
{errors.category && <span>This field is required</span>}
<br />
<label>Content: </label>
<br />
<textarea
{...register('content', { required: true })}
rows={10}
cols={50}
/>
{errors.content && <span>This field is required</span>}
<br />
{queryResult?.data?.data?.thumbnail && (
<>
<br />
<label>Image: </label>
<br />
<img
src={queryResult?.data?.data?.thumbnail}
width={200}
height={200}
/>
<br />
<br />
</>
)}
<input type="submit" value="Submit" />
{formLoading && <p>Loading</p>}
</form>
)
}
If you want to show a form in a modal or drawer where necessary route params might not be there you can use the useModalForm.
Properties
action
useForm can handle edit, create and clone actions.
By default, it determines the action from route.
- If the route is
/posts/createthus the hook will be called withaction: "create". - If the route is
/posts/edit/1, the hook will be called withaction: "edit". - If the route is
/posts/clone/1, the hook will be called withaction: "clone". To display form, usescreatecomponent from resource.
It can be overridden by passing the action prop where it isn't possible to determine the action from the route (e.g. when using form in a modal or using a custom route).
- create
- edit
- clone
action: "create" is used for creating a new record that didn't exist before.
useForm uses useCreate under the hood for mutations on create mode.
In the following example, we'll show how to use useForm with action: "create".
action: "edit" is used for editing an existing record. It requires the id for determining the record to edit. By default, it uses the id from the route. It can be changed with the setId function or id property.
It fetches the record data according to the id with useOne and returns the queryResult for you to fill the form. After the form is submitted, it updates the record with useUpdate.
In the following example, we'll show how to use useForm with action: "edit".
action: "clone" is used for cloning an existing record. It requires the id for determining the record to clone. By default, it uses the id from the route. It can be changed with the setId function.
You can think action:clone like save as. It's similar to action:edit but it creates a new record instead of updating the existing one.
It fetches the record data according to the id with useOne and returns the queryResult for you to fill the form. After the form is submitted, it creates a new record with useCreate.
In the following example, we'll show how to use useForm with action: "clone".
resource
Default: It reads the
resourcevalue from the current URL.
It will be passed to the dataProvider's method as a params. This parameter is usually used to as a API endpoint path. It all depends on how to handle the resource in your dataProvider. See the creating a data provider section for an example of how resource are handled.
- When
actionis"create", it will be passed to thecreatemethod from thedataProvider. - When
actionis"edit", it will be passed to theupdateand thegetOnemethod from thedataProvider. - When
actionis"clone", it will be passed to thecreateand thegetOnemethod from thedataProvider.
useForm({
resource: 'categories',
})
id
id is used for determining the record to edit or clone. By default, it uses the id from the route. It can be changed with the setId function or id property.
It is usefull when you want to edit or clone a resource from a different page.
Note:
idis required whenaction: "edit"oraction: "clone".
useForm({
refineCoreProps: {
action: 'edit', // or clone
resource: 'categories',
id: 1, // <BASE_URL_FROM_DATA_PROVIDER>/categories/1
},
})
redirect
redirect is used for determining the page to redirect after the form is submitted. By default, it uses the list. It can be changed with the redirect property.
It can be set to "show" | "edit" | "list" | "create" or false to prevent the page from redirecting to the list page after the form is submitted.
useForm({
refineCoreProps: {
redirect: false,
},
})
onMutationSuccess
It's a callback function that will be called after the mutation is successful.
It receives the following parameters:
data: Returned value fromuseCreateoruseUpdatedepending on theaction.variables: The variables passed to the mutation.context: react-query context.
useForm({
refineCoreProps: {
onMutationSuccess: (data, variables, context) => {
console.log({ data, variables, context })
},
},
})
onMutationError
It's a callback function that will be called after the mutation is failed.
It receives the following parameters:
data: Returned value fromuseCreateoruseUpdatedepending on theaction.variables: The variables passed to the mutation.context: react-query context.
useForm({
refineCoreProps: {
onMutationError: (data, variables, context) => {
console.log({ data, variables, context })
},
},
})
invalidates
You can use it to manage the invalidations that will occur at the end of the mutation.
By default it's invalidates following queries from the current resource:
- on
createorclonemode:"list"and"many" - on
editmode:"list","many"and"detail"
useForm({
refineCoreProps: {
invalidates: ['list', 'many', 'detail'],
},
})
dataProviderName
If there is more than one dataProvider, you should use the dataProviderName that you will use.
It is useful when you want to use a different dataProvider for a specific resource.
If you want to use a different dataProvider on all resource pages, you can use the dataProvider prop of the <Refine> component.
useForm({
refineCoreProps: {
dataProviderName: 'second-data-provider',
},
})
mutationMode
Mutation mode determines which mode the mutation runs with. Mutations can run under three different modes: pessimistic, optimistic and undoable. Default mode is pessimistic.
Each mode corresponds to a different type of user experience.
For more information about mutation modes, please check Mutation Mode documentation page.
useForm({
refineCoreProps: {
mutationMode: 'undoable', // "pessimistic" | "optimistic" | "undoable",
},
})
successNotification
NotificationProvideris required for this prop to work.
After form is submitted successfully, useForm will call open function from NotificationProvider to show a success notification. With this prop, you can customize the success notification.
useForm({
refineCoreProps: {
successNotification: (data, values, resource) => {
return {
message: `Post Successfully created with ${data.title}`,
description: 'Success with no errors',
type: 'success',
}
},
},
})
errorNotification
NotificationProvideris required for this prop to work.
After form is submit is failed, refine will show a error notification. With this prop, you can customize the error notification.
useForm({
refineCoreProps: {
action: 'create',
resource: 'post',
errorNotification: (data, values, resource) => {
return {
message: `Something went wrong when deleting ${data.id}`,
description: 'Error',
type: 'error',
}
},
},
})
{
"message": "Error when updating <resource-name> (status code: ${err.statusCode})" or "Error when creating <resource-name> (status code: ${err.statusCode})",
"description": "Error",
"type": "error",
}
metaData
metaData is used following two purposes:
- To pass additional information to data provider methods.
- Generate GraphQL queries using plain JavaScript Objects (JSON). Please refer GraphQL for more information.
In the following example, we pass the headers property in the metaData object to the create method. With similar logic, you can pass any properties to specifically handle the data provider methods.
useForm({
refineCoreProps: {
metaData: {
headers: { 'x-meta-data': 'true' },
},
},
})
const myDataProvider = {
//...
create: async ({ resource, variables, metaData }) => {
const headers = metaData?.headers ?? {}
const url = `${apiUrl}/${resource}`
const { data } = await httpClient.post(url, variables, { headers })
return {
data,
}
},
//...
}
queryOptions
Works only in
action: "edit"oraction: "clone"mode.
in edit or clone mode, refine uses useOne hook to fetch data. You can pass queryOptions options by passing queryOptions property.
useForm({
refineCoreProps: {
queryOptions: {
retry: 3,
},
},
})
createMutationOptions
This option is only available when
action: "create"oraction: "clone".
In create or clone mode, refine uses useCreate hook to create data. You can pass mutationOptions by passing createMutationOptions property.
useForm({
refineCoreProps: {
queryOptions: {
retry: 3,
},
},
})
updateMutationOptions
This option is only available when
action: "edit".
In edit mode, refine uses useUpdate hook to update data. You can pass mutationOptions by passing updateMutationOptions property.
useForm({
refineCoreProps: {
queryOptions: {
retry: 3,
},
},
})
warnWhenUnsavedChanges
Default:
false
When it's true, Shows a warning when the user tries to leave the page with unsaved changes. It can be used to prevent the user from accidentally leaving the page.
It can be set globally in refine config.
useForm({
refineCoreProps: {
warnWhenUnsavedChanges: true,
},
})
liveMode
Whether to update data automatically ("auto") or not ("manual") if a related live event is received. It can be used to update and show data in Realtime throughout your app. For more information about live mode, please check Live / Realtime page.
useForm({
refineCoreProps: {
liveMode: 'auto',
},
})
onLiveEvent
The callback function that is executed when new events from a subscription are arrived.
useForm({
refineCoreProps: {
onLiveEvent: (event) => {
console.log(event)
},
},
})
liveParams
Params to pass to liveProvider's subscribe method.
Return Values
queryResult
If the action is set to "edit" or "clone" or if a resource with an id is provided, useForm will call useOne and set the returned values as the queryResult property.
const {
refineCore: { queryResult },
} = useForm()
const { data } = queryResult
mutationResult
When in "create" or "clone" mode, useForm will call useCreate. When in "edit" mode, it will call useUpdate and set the resulting values as the mutationResult property."
const {
refineCore: { mutationResult },
} = useForm()
const { data } = mutationResult
setId
useForm determine id from the router. If you want to change the id dynamically, you can use setId function.
const {
refineCore: { id, setId },
} = useForm()
const handleIdChange = (id: string) => {
setId(id)
}
return (
<div>
<input value={id} onChange={(e) => handleIdChange(e.target.value)} />
</div>
)
redirect
"By default, after a successful mutation, useForm will redirect to the "list" page. To redirect to a different page, you can either use the redirect function to programmatically specify the destination, or set the redirect property in the hook's options.
In the following example we will redirect to the "show" page after a successful mutation.
const {
refineCore: { onFinish, redirect },
} = useForm()
// --
const handleSubmit = async (e: React.FormEvent<HTMLFormElement>) => {
e.preventDefault()
const data = await onFinish(formValues)
redirect('show', data?.data?.id)
}
// --
onFinish
onFinish is a function that is called when the form is submitted. It will call the appropriate mutation based on the action property.
You can override the default behavior by passing an onFinish function in the hook's options.
For example you can change values before sending to the API.
formLoading
Loading state of a modal. It's true when useForm is currently being submitted or data is being fetched for the "edit" or "clone" mode.
FAQ
How can Invalidate other resources?
You can invalidate other resources with help of useInvalidate hook.
It is useful when you want to invalidate other resources don't have relation with the current resource.
import React from 'react'
import { useInvalidate } from '@pankod/refine-core'
import { useForm } from '@pankod/refine-react-hook-form'
const PostEdit = () => {
const invalidate = useInvalidate()
useForm({
refineCoreProps: {
onMutationSuccess: (data, variables, context) => {
invalidate({
resource: 'users',
invalidates: ['resourceAll'],
})
},
},
})
// ---
}
How can I change the form data before submitting it to the API?
You may need to modify the form data before it is sent to the API.
For example, Let's send the values we received from the user in two separate inputs, name and surname, to the API as fullName.
import React from 'react'
import { FieldValues, useForm } from '@pankod/refine-react-hook-form'
export const UserCreate: React.FC = () => {
const {
refineCore: { onFinish },
register,
handleSubmit,
} = useForm()
const onFinishHandler = (data: FieldValues) => {
onFinish({
fullName: `${data.name} ${data.surname}`,
})
}
return (
<form onSubmit={handleSubmit(onFinishHandler)}>
<label>Name: </label>
<input {...register('name')} />
<br />
<label>Surname: </label>
<input {...register('surname')} />
<br />
<button type="submit">Submit</button>
</form>
)
}
API
Properties
*: These properties have default values inRefineContextand can also be set on the <Refine> component.
It also accepts all props of useForm hook available in the React Hook Form.
For example, we can define the
refineCorePropsproperty in theuseFormhook as:
import { useForm } from "@pankod/refine-react-hook-form";
const { ... } = useForm({
...,
refineCoreProps: {
resource: "posts",
redirect: false,
// You can define all properties provided by refine useForm
},
});
Return values
Returns all the properties returned by React Hook Form of the useForm hook. Also, we added the following return values:
refineCore: Returns all values returned by useForm. You can see all of them in here.
For example, we can access the
refineCorereturn value in theuseFormhook as:
import { useForm } from "@pankod/refine-react-hook-form";
const {
refineCore: { queryResult, ... },
} = useForm({ ... });
