问题在于表单的上下文,该表单用于编辑角色的属性,包括通过复选框选择的相关权限。
在加载表单后,根据检索到的角色数据,某些权限的复选框会按预期显示为选中状态。可以选择和取消选择空的复选框,并且更改会反映在浏览器的请求有效负载预览数组上,尽管添加的新值在数组上显示为字符串,如您所见:
role_permissions: [1, 2, 3, 4, 5, "6"]
但是,这就是问题所在,当取消选择加载表单时默认选中的复选框时,它们的行为很奇怪,不允许取消选中多个复选框,并且浏览器的请求有效负载预览上的数组根本无法更新
Laravel视图:
<div class="card-body">
<livewire:roles.form-edit :role="$role" />
</div>
Livewire控制器:
class FormEdit extends Component
{
public $role;
public $name;
public $permissions;
public $role_permissions;
public $notes;
public function mount($role)
{
$this->role = $role;
$this->name = $role->name;
$this->permissions = Permission::all();
$this->role_permissions = $role->permissions()->pluck('id')->toArray();
$this->notes = $role->notes;
}
public function update()
{
$role_data = $this->validate([
'name' => ['required', 'string', 'min:1', 'max:255', Rule::unique('roles')->ignore($this->role->id)],
'permissions' => 'nullable',
'notes' => 'nullable',
]);
$this->role->update([
'name' => $role_data['name'],
'notes' => $role_data['notes'],
]);
$this->role->permissions()->sync($this->role_permissions);
session()->flash('success_message', "Rol actualizado correctamente.");
return redirect()->route('backend.roles.role.index');
}
public function render()
{
return view('livewire.roles.form-edit');
}
}
Livewire视图:
<form wire:submit.prevent="update" accept-charset="UTF-8" id="edit_role_form" class="form-horizontal">
<x-input.text label="Name" attribute="name" />
<x-input.checkboxes label="Permissions" attribute="role_permissions" :options="$permissions" :entity-options="$role_permissions" />
<x-input.textarea label="Notes" attribute="notes" />
<x-input.submit label="Save" />
</form>

更新:我只是摆脱了
已解决。我仍然爱上Livewire。我真的不想学习Javascript框架。
答案 0 :(得分:0)
乍一看,您似乎需要修复 update()
函数。 Livewire 没有挂钩。您需要执行 updating()
或 updated()
