Edit action

#概述

Filament 包含一个可以编辑 Eloquent 记录的预制 Action。点击触发按钮后，会打开一个带有表单的模态框。用户填写表单，数据经过验证后存入到数据库。你可以这样使用：

use Filament\Actions\EditAction;
use Filament\Forms\Components\TextInput;
 
EditAction::make()
    ->record($this->post)
    ->form([
        TextInput::make('title')
            ->required()
            ->maxLength(255),
        // ...
    ])
use Filament\Actions\EditAction;
use Filament\Forms\Components\TextInput;

EditAction::make()
    ->record($this->post)
    ->form([
        TextInput::make('title')
            ->required()
            ->maxLength(255),
        // ...
    ])

如果你想要编辑表格行记录，你可以使用 Filament\Tables\Actions\EditAction：

use Filament\Forms\Components\TextInput;
use Filament\Tables\Actions\EditAction;
use Filament\Tables\Table;
 
public function table(Table $table): Table
{
    return $table
        ->actions([
            EditAction::make()
                ->form([
                    TextInput::make('title')
                        ->required()
                        ->maxLength(255),
                    // ...
                ]),
        ]);
}
use Filament\Forms\Components\TextInput;
use Filament\Tables\Actions\EditAction;
use Filament\Tables\Table;

public function table(Table $table): Table
{
    return $table
        ->actions([
            EditAction::make()
                ->form([
                    TextInput::make('title')
                        ->required()
                        ->maxLength(255),
                    // ...
                ]),
        ]);
}

#表单填充前自定义数据

如果你想要在数据填充到表单前，对数据进行修改；你可以使用 mutateRecordDataUsing() 方法，修改 $data 数组，并且返回其填充到表单前修改的版本：

EditAction::make()
    ->mutateRecordDataUsing(function (array $data): array {
        $data['user_id'] = auth()->id();
 
        return $data;
    })
EditAction::make()
    ->mutateRecordDataUsing(function (array $data): array {
        $data['user_id'] = auth()->id();

        return $data;
    })

#保存前自定义数据

有时候，你可能希望在表单数据存入数据库之前对其进行修改。为此你可以使用 mutateFormDataUsing() 方法，该方法将 $data 当作数组访问，并返回修改后的版本：

EditAction::make()
    ->mutateFormDataUsing(function (array $data): array {
        $data['last_edited_by_id'] = auth()->id();
 
        return $data;
    })
EditAction::make()
    ->mutateFormDataUsing(function (array $data): array {
        $data['last_edited_by_id'] = auth()->id();

        return $data;
    })

#自定义保存过程

你可以使用 using() 方法微调记录的更新方式：

use Illuminate\Database\Eloquent\Model;
 
EditAction::make()
    ->using(function (Model $record, array $data): Model {
        $record->update($data);
 
        return $record;
    })
use Illuminate\Database\Eloquent\Model;

EditAction::make()
    ->using(function (Model $record, array $data): Model {
        $record->update($data);

        return $record;
    })

#保存后重定向

使用 successRedirectUrl() 方法中，你可以对表单提交后的重定向进行自定义设置：

EditAction::make()
    ->successRedirectUrl(route('posts.list'))
EditAction::make()
    ->successRedirectUrl(route('posts.list'))

如果你想要使用更新后的记录进行重定向，请使用 $record 参数：

use Illuminate\Database\Eloquent\Model;
 
EditAction::make()
    ->successRedirectUrl(fn (Model $record): string => route('posts.view', [
        'post' => $record,
    ]))
use Illuminate\Database\Eloquent\Model;

EditAction::make()
    ->successRedirectUrl(fn (Model $record): string => route('posts.view', [
        'post' => $record,
    ]))

#自定义保存通知

记录更新成功后，会发送一个通知给用户，说明操作成功：

要自定义通知标题，请使用 successNotificationTitle() 方法：

EditAction::make()
    ->successNotificationTitle('User updated')
EditAction::make()
    ->successNotificationTitle('User updated')

使用 successNotification() 方法，你可以自定义整个通知：

use Filament\Notifications\Notification;
 
EditAction::make()
    ->successNotification(
       Notification::make()
            ->success()
            ->title('User updated')
            ->body('The user has been saved successfully.'),
    )
use Filament\Notifications\Notification;

EditAction::make()
    ->successNotification(
       Notification::make()
            ->success()
            ->title('User updated')
            ->body('The user has been saved successfully.'),
    )

要完全禁用通知，请使用 successNotification(null) 方法：

EditAction::make()
    ->successNotification(null)
EditAction::make()
    ->successNotification(null)

#生命周期钩子

钩子可用在 Action 生命周期的各种节点中执行代码，比如表单数据保存之前。

可用的钩子有：

EditAction::make()
    ->beforeFormFilled(function () {
        // Runs before the form fields are populated from the database.
    })
    ->afterFormFilled(function () {
        // Runs after the form fields are populated from the database.
    })
    ->beforeFormValidated(function () {
        // Runs before the form fields are validated when the form is saved.
    })
    ->afterFormValidated(function () {
        // Runs after the form fields are validated when the form is saved.
    })
    ->before(function () {
        // Runs before the form fields are saved to the database.
    })
    ->after(function () {
        // Runs after the form fields are saved to the database.
    })
EditAction::make()
    ->beforeFormFilled(function () {
        // Runs before the form fields are populated from the database.
    })
    ->afterFormFilled(function () {
        // Runs after the form fields are populated from the database.
    })
    ->beforeFormValidated(function () {
        // Runs before the form fields are validated when the form is saved.
    })
    ->afterFormValidated(function () {
        // Runs after the form fields are validated when the form is saved.
    })
    ->before(function () {
        // Runs before the form fields are saved to the database.
    })
    ->after(function () {
        // Runs after the form fields are saved to the database.
    })

#中断保存处理过程

在任何时候，你都可以在生命周期钩子或者 mutation 方法中，调用 $action->halt()，中断整个保存处理过程：

use Filament\Notifications\Actions\Action;
use Filament\Notifications\Notification;
use Filament\Tables\Actions\EditAction;
 
EditAction::make()
    ->before(function (EditAction $action) {
        if (! $this->record->team->subscribed()) {
            Notification::make()
                ->warning()
                ->title('You don\'t have an active subscription!')
                ->body('Choose a plan to continue.')
                ->persistent()
                ->actions([
                    Action::make('subscribe')
                        ->button()
                        ->url(route('subscribe'), shouldOpenInNewTab: true),
                ])
                ->send();
        
            $action->halt();
        }
    })
use Filament\Notifications\Actions\Action;
use Filament\Notifications\Notification;
use Filament\Tables\Actions\EditAction;

EditAction::make()
    ->before(function (EditAction $action) {
        if (! $this->record->team->subscribed()) {
            Notification::make()
                ->warning()
                ->title('You don\'t have an active subscription!')
                ->body('Choose a plan to continue.')
                ->persistent()
                ->actions([
                    Action::make('subscribe')
                        ->button()
                        ->url(route('subscribe'), shouldOpenInNewTab: true),
                ])
                ->send();
        
            $action->halt();
        }
    })

如果你想同时关闭 Action 模态框，你可以使用 cancel() 完全取消该 Action：

$action->cancel();
$action->cancel();
