The following is the tutorial column of Laravel to introduce the release of Dcat Admin v2.0.0-BETA. I hope it will be helpful to friends in need!
PrefaceHi, hello classmates! After many days, Dcat Admin
finally ushered in the first version of2.0. Here is a brief introduction to the main changes. Everyone is welcome to install and experience it. If there are any problems, they will be fixed immediately~Installation
The v2.0.1-beta version has been released
composer require dcat/laravel-admin:v2.0.1-beta -vvv
What are the changes?
1. Extension We have focused on optimizing the extension
function in this version, mainly simplifying The extension usage process allows users to install, uninstall, and upgrade extensions through the page, and supports both page compression andcomposer installation methods. The App Market function will be launched when the official version is released, so stay tuned~The detailed usage documentation will be gradually updated this week~
2. Enhance form layout capabilitiesIn 2.0
, we have The block layout function has been refactored to support more complex layouts. Example
$form->block(8, function (Form\BlockForm $form) {
$form->title('基本设置');
$form->showFooter();
$form->width(9, 2);
$form->column(6, function (Form\BlockForm $form) {
$form->display('id');
$form->text('name');
$form->email('email');
$form->image('avatar');
$form->password('password');
});
$form->column(6, function (Form\BlockForm $form) {
$form->text('username');
$form->email('mobile');
$form->textarea('description');
});
});
$form->block(4, function (Form\BlockForm $form) {
$form->title('分块2');
$form->text('nickname');
$form->number('age');
$form->radio('status')->options(['1' => '默认', 2 => '冻结'])->default(1);
$form->next(function (Form\BlockForm $form) {
$form->title('分块3');
$form->date('birthday');
$form->date('created_at');
});
});##2.0
is also supported in
Nested layouts use column and rows layouts, such as This function supports both data forms
Tool form3. Refactor the form response method
$form->tab('标题', function (Form $form) { $form->column(6, function (Form $form) { ... }); $form->column(6, function (Form $form) { ... });});
in version1.0 The response methods of the form are only
success, error and redirect, which cannot meet some more complex scenarios. In 2.0 we let the form The response methods of action are unified to support more functions and reduce the learning cost of developers. In the data form<pre class="brush:php;toolbar:false">$form->saving(function (Form $form) {
return $form
->response()
->success('保存成功')
->script('console.log("执行JS代码")')
->redirect('auth/users');});</pre>In the tool form
public function handle(array $input){
...
return $this
->response()
->alert()
->success('成功')
->detail('详细内容');}
4. Separation of JS code and PHP codeThis function is a follow-up to the new features of laravel-admin2.0 version. In 2.0, it is recommended to put the
JS code into the view file, example The code in <pre class="brush:php;toolbar:false"><style>
.popover{z-index:29891015}
</style>
<div class="{{$viewClass[&#39;form-group&#39;]}}">
<div for="{{ $id }}" class="{{$viewClass[&#39;label&#39;]}} control-label">
<span>{!! $label !!}</span>
</div>
<div class="{{$viewClass[&#39;field&#39;]}}">
@include(&#39;admin::form.error&#39;)
<div class="input-group">
<span class="input-group-prepend"><span class="input-group-text bg-white" style="padding: 4px"><i style="width: 24px;height: 100%;background: {!! $value !!}"></i></span></span>
<input {!! $attributes !!} />
@if ($append)
<span class="input-group-append">{!! $append !!}</span>
@endif
</div>
@include(&#39;admin::form.help-block&#39;)
</div>
</div>
<script require="@color">
$(&#39;{{ $selector }}&#39;).colorpicker({!! json_encode($options) !!}).on(&#39;colorpickerChange&#39;, function(event) {
$(this).parents(&#39;.input-group&#39;).find(&#39;.input-group-prepend i&#39;).css(&#39;background-color&#39;, event.color.toString());
});
</script></pre>3f1c4e4b6b16bbbd69b2ee476dc4f83a and
tags will be extracted and compiled, and Admin::script() will be implemented. The same processing effect as Admin::style(). It should be noted that 3f1c4e4b6b16bbbd69b2ee476dc4f83a and c9ccee2e6ea535a969eb3f532ad9fe89 must be root tags and cannot be Wrap it in other tags, otherwise the extraction will fail!
There are some column selectors in 1.x Due to compatibility issues, some special types of tables are not compatible, so in
2.0 we reconstructed the column selector function and abandoned the old API (responsive). The new column selector function is perfectly compatible with the fixed column and
functions, and supports the remember user operation function, which will automatically remember the user's selection , the effect is as follows
in1.0 The design of table events is relatively random and non-standard, so we reconstructed the table events in
2.0 and added some events. The usage of the new table events is as follows<pre class="brush:php;toolbar:false">use Dcat\Admin\Grid;
Grid::make(new Model(), function (Grid $grid) {
$grid->listen(Grid\Events\Fetching::class, function (Grid $grid) {
...
});
});</pre>If You want to listen to allGrid
use Dcat\Admin\Grid;
use Illuminate\Support\Facades\Event;
Event::listen(Grid\Events\Fetching::class, function (Grid $grid) {
...
});
// 或者
Grid::resolving(function (Grid $grid) {
$grid->listen(Grid\Events\Fetching::class, function (Grid $grid) {
...
});
});For more usage of events, please refer to the relevant documentation
在 8.重构模型树行操作 在 9.增加settings配置表 在新版本中增加了 10.数据仓库接口重命名 在 更多变动 我们在 关于应用市场和新主题 应用市场会在正式版发布时同步上线；2.0中如果Grid表格使用的是model渲染数据，则可以在数据行相关回调中直接使用model的对象，如$grid->clolumn('avatar')->display(function () {
// getAvatar是model中的自定义方法，这里可以直接调用
return $this->getAvatar();
});2.0中我们对模型树的行操作功能进行了重构，新的行操作功能和数据表格的行操作功能用法一致use Dcat\Admin\Tree;
$tree->actions(function (Tree\Actions $actions) {
if ($actions->row->id > 5) {
$actions->disableDelete(); // 禁用删除按钮
}
// 添加新的action
$actions->append(...);
});
// 批量添加action
$tree->actions([
new Action1(),
"<div>...</div>",
...
]);settings配置表，目前主要用于保存扩展的启用和禁用配置数据，可以通过以下方式读写配置// 读取
admin_settings('key1', '默认值');
admin_settings('arr.k1', '默认值');
// 保存配置
admin_settings([
'key1' => ['v1'],
'arr.k1' => 'v1',
]);2.0中我们对数据仓库的接口命名做了简化处理，新的interface如下interface Repository{
/**
* 获取主键名称.
*
* @return string
*/
public function getKeyName();
/**
* 获取创建时间字段.
*
* @return string
*/
public function getCreatedAtColumn();
/**
* 获取更新时间字段.
*
* @return string
*/
public function getUpdatedAtColumn();
/**
* 是否使用软删除.
*
* @return bool
*/
public function isSoftDeletes();
/**
* 获取Grid表格数据.
*
* @param Grid\Model $model
*
* @return \Illuminate\Contracts\Pagination\LengthAwarePaginator|Collection|array
*/
public function get(Grid\Model $model);
/**
* 获取编辑页面数据.
*
* @param Form $form
*
* @return array|\Illuminate\Contracts\Support\Arrayable
*/
public function edit(Form $form);
/**
* 获取详情页面数据.
*
* @param Show $show
*
* @return array|\Illuminate\Contracts\Support\Arrayable
*/
public function detail(Show $show);
/**
* 新增记录.
*
* @param Form $form
*
* @return mixed
*/
public function store(Form $form);
/**
* 查询更新前的行数据.
*
* @param Form $form
*
* @return array|\Illuminate\Contracts\Support\Arrayable
*/
public function updating(Form $form);
/**
* 更新数据.
*
* @param Form $form
*
* @return bool
*/
public function update(Form $form);
/**
* 删除数据.
*
* @param Form $form
* @param array $deletingData
*
* @return mixed
*/
public function delete(Form $form, array $deletingData);
/**
* 查询删除前的行数据.
*
* @param Form $form
*
* @return array|\Illuminate\Contracts\Support\Arrayable
*/
public function deleting(Form $form);}
Dcat\Admin\Http\Controllers
zh-CN更新为zh_CN）vendors更改为vendor
2.0中做了大量的细节改进，对许多功能接口都做了调整和代码优化，限于篇幅这里不再一一列出，详细说明会放在1.x升级指导文档中（文档即将在这几天内发布）。
新主题会开发成插件，也会在正式版发布时同步上线~
