在我的crud控制器中,有一个名为“角色(多个清单)”的字段,在保存角色之前,我正在使用implode将数组转换为类似1,2,3
的字符串。
例如:CrudController
setUp()
方法
$options = [
'name' => 'roles',
'label' => 'Roles',
'type' => 'checklist',
'entity' => 'roles',
'attribute' => 'name',
'model' => "Backpack\PermissionManager\app\Models\Role",
];
$this->crud->addField($options);
在商店方法中,
public function store(StoreRequest $request)
{
$sel_roles = $request->input("roles");
$roles = !empty($sel_roles) ? implode(",",$sel_roles) : "";
$request->request->set("roles",$roles);
//dd($request);
return parent::storeCrud($request);
}
编辑方法如下所示,
public function edit($id) {
$this->crud->hasAccessOrFail('update');
// get the info for that entry
$this->data['entry']= $this->crud->getEntry($id);
$options = [
'name' => 'roles',
'label' => 'Roles',
'type' => 'checklist',
'entity' => 'roles',
'attribute' => 'name',
'model' => "Backpack\PermissionManager\app\Models\Role",
];
$this->crud->addField($options);
$this->data['crud'] = $this->crud;
$this->data['fields'] = $this->crud->getUpdateFields($id);
$this->data['id'] = $id;
return view('crud::edit', $this->data);
}
如果尝试访问“编辑”页面,则出现以下错误消息,
第15行中的ErrorException: 在字符串上调用成员函数pluck()(查看:/var/www/html/app/vendor/backpack/crud/src/resources/views/fields/checklist.blade.php)
checklist.blade.php
页面如下所示
<div @include('crud::inc.field_wrapper_attributes') >
<label>{!! $field['label'] !!}</label>
<?php $entity_model = $crud->getModel(); ?>
<div class="row">
@foreach ($field['model']::all() as $connected_entity_entry)
<div class="col-sm-4">
<div class="checkbox">
<label>
<input type="checkbox"
name="{{ $field['name'] }}[]"
value="{{ $connected_entity_entry->id }}"
@if( ( old( $field["name"] ) && in_array($connected_entity_entry->id, old( $field["name"])) ) || (isset($field['value']) && in_array($connected_entity_entry->id, $field['value']->pluck('id', 'id')->toArray())))
checked = "checked"
@endif > {!! $connected_entity_entry->{$field['attribute']} !!}
</label>
</div>
</div>
@endforeach
</div>
{{-- HINT --}}
@if (isset($field['hint']))
<p class="help-block">{!! $field['hint'] !!}</p>
@endif
</div>
如何在编辑页面中显示具有选定值的角色。
谢谢

经过数小时的调试和验证,
以收集格式发送编辑值,
$options = [
'name' => 'role_id',
'label' => 'Roles',
'type' => 'checklist',
'entity' => 'roles',
'attribute' => 'name',
'model' => "Backpack\PermissionManager\app\Models\Role",
"value" => collect([$edit_value_array])
];
