Laravel 错误方法

Question

Laravel 基础知识：

我有以下路线：

Route::group(['prefix' => 'pps',  'as' => 'pps.', 'middleware' => ['auth']], function (){

Route::get('/index', 'PPS\PPSController@index')->name('index');
/**
 * Templates
 */
Route::group(['prefix' => 'templates',  'as' => 'templates.', 'middleware' => ['auth']], function (){

    Route::get('/', 'PPS\Template\TemplateController@index')->name('index');
    /**
     * Sequence group
     */
    Route::group(['prefix' => 'sequenceGroup',  'as' => 'sequenceGroup.', 'middleware' => ['auth']], function (){

        Route::get('/', 'PPS\Template\SequenceGroupController@index')->name('index');
        Route::get('/create', 'PPS\Template\SequenceGroupController@create')->name('create');
        Route::post('/store', 'PPS\Template\SequenceGroupController@store')->name('store');
        Route::get('/edit/{sequenceGroup}', 'PPS\Template\SequenceGroupController@edit')->name('edit');
        Route::put('/update/{sequenceGroup}', 'PPS\Template\SequenceGroupController@update')->name('update');
        Route::delete('/delete/{sequenceGroup}', 'PPS\Template\SequenceGroupController@delete')->name('delete');
    });
    /**
     * Sequence template
     */
    Route::group(['prefix' => 'sequenceTemplates',  'as' => 'sequenceTemplates.', 'middleware' => ['auth']], function (){

        Route::get('/{sequenceGroup}', 'PPS\Template\SequenceTemplateController@index')->name('index');
        Route::get('/create/{sequenceGroup}', 'PPS\Template\SequenceTemplateController@create')->name('create');
        Route::post('/store', 'PPS\Template\SequenceTemplateController@store')->name('store');
        Route::get('/edit/{sequenceTemplate}', 'PPS\Template\SequenceTemplateController@edit')->name('edit');
        Route::put('/update/{sequenceTemplate}', 'PPS\Template\SequenceTemplateController@update')->name('update');
        Route::delete('/delete/{sequenceTemplate}', 'PPS\Template\SequenceTemplateController@delete')->name('delete');
    });
});


});

当我更新序列组时，一切正常。但是当我更新序列模板时，Laravel 总是转到编辑方法而不是更新方法。

这是我的表格：

 <form action="{{ route('pps.templates.sequenceTemplates.update', $sequenceTemplate->id) }}" method="post">
            {{ csrf_field() }}
            {{ method_field('put') }}
            <div class="form-group{{ $errors->has('name') ? ' has-error' : '' }}">
                <label for="name" class="control-label">@lang('pps.name')</label>
                <input type="text" name="name" id="name" class="form-control" value="{{ old('name', $sequenceTemplate->name) }}">
                @if ($errors->has('name'))
                    <span class="help-block">
                        <strong>{{ $errors->first('name') }}</strong>
                    </span>
                @endif
            </div>
            <div class="form-group{{ $errors->has('description') ? ' has-error' : '' }}">
                <label for="description" class="control-label">@lang('pps.description')</label>
                <input type="text" name="description" id="description" class="form-control" value="{{ old('description', $sequenceTemplate->description) }}">
                @if ($errors->has('description'))
                    <span class="help-block">
                        <strong>{{ $errors->first('description') }}</strong>
                    </span>
                @endif
            </div>


            <button type="submit" class="btn btn-primary">@lang('pps.save')</button>
        </form>

控制器：

    public function edit(SequenceTemplate $sequenceTemplate)
{

    return view('pps.template.sequenceTemplate.edit', compact('sequenceTemplate'));
}

public function update(UpdateSequenceTemplateRequest $request, SequenceTemplate $sequenceTemplate)
{

    $sequenceTemplate->update($request->except('_token', '_method'));
    return redirect()->route('pps.templates.sequenceTemplate.index')->withSuccess(__('sequenceTemplateUpdated'));
}

要求：

<?php

namespace App\Http\Requests\PPS\Template;

use Illuminate\Foundation\Http\FormRequest;

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

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

    return [
        'sequence_group_id' => 'required|integer',
        'name' => 'required|string|min:3',

    ];
}
}

出了什么问题？我没有发现错误。

Answer 1

当您填写表单并按提交按钮时，Laravel 会验证数据并将您重定向回来，因为表单中没有

sequence_group_id

并且该字段是必填字段：

'sequence_group_id' => 'required|integer',

并且您没有看到任何错误消息，因为您没有尝试显示它

sequence_group_id

。要测试它，请将其放在表单的顶部：

Errors: {{ dump($errors->all()) }}

并尝试提交表格。
