Laravel-更新日期的验证规则 [英] Laravel - validation rule for date on update

问题描述

我有此验证规则:

'event_start' => 'required|date|after:today',

在创建模型时一切都很好，这个日期不能早于今天....

and on creating a model all is fine, this date cannot be before today....

但是当用户尝试更新事件的开始日期是今天之前，并且弹出验证错误....是否可以通过调整方法来更新模型?这样，当用户更新此规则时，仅检查是否是日期?

but when a user tries to update the event start date is before today and a validation error pops up....is there a way to adjust this for updating the model? So that when a user updates this rule checks only if it is a date?

更新

这是我对创建和更新的唯一验证检查:

this is my only validation check for both create and update:

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class EventsForm extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        if( auth()->check() )
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        $rules = [

            'title' => 'required|min:2|max:255',
            'event_start' => 'required|date|after:today',

        ];

        return $rules;
    }
}

推荐答案

您应该具有用于​​创建和更新事件的不同表单请求类.但这并不是说您不能使用继承.

You should have different form request classes for creating and updating events. That’s not to say you can’t use inheritance, though.

如果您的更新方法仅与创建方法不同，那么您可以扩展该方法的表单请求并修改更新规则:

If your update method only slightly differs from the create method, then you could extend that method’s form request and amend the rules for update:

class CreateEventRequest extends FormRequest
{
    public function authorize()
    {
        return true;
    }

    public function rules()
    {
        return [
            'name' => 'required|unique:events',
            'start_date' => 'required|date|after:today',
            'door_time' => 'required|date_format:"H:i:s",
            'location' => 'required',
        ];
    }
}

然后……

class UpdateEventRequest extends CreateEventRequest
{
    public function rules()
    {
        // Get ID of event if using route–model binding
        $id = $this->route('event')->getKey();

        // Use array merge to override create event form request’s rules
        return array_merge(parent::rules(), [
            'name' => 'required|unique:events,name,'.$id,
            'start_date' => 'required|date',
        ]);
    }
}

您甚至可以将rules方法推送到抽象类，并让您的创建和更新表单请求类扩展 that 类:

You could even push the rules method to an abstract class, and have your create and update form request classes extend that class:

abstract class EventFormRequest extends FormRequest
{
    public function authorize()
    {
        return true;
    }

    public function rules()
    {
        // Base event rules
    }
}

class CreateEventRequest extends EventFormRequest
{
    public function rules()
    {
        // Create-specific rules
    }
}

class UpdateEventRequest extends EventFormRequest
{
    public function rules()
    {
        // Update-specific rules
    }
}
