laravel8.5与layuiadmin整合(12)

57.给角色分配权限
/app/Http/Controllers/Admin/RoleController.php
添加

   /**
     * 编辑角色的权限
     * @param Request $request
     * @param $id
     * @return \Illuminate\Contracts\View\Factory|\Illuminate\Contracts\View\View
     */
    public function permission(Request $request, $id) {
        $role = Role::findOrFail($id);
        $permissions = $this->tree();

        foreach ($permissions as $key1 => $item1){
            $permissions[$key1]['own'] = $role->hasPermissionTo($item1['id']) ? 'checked' : false ;
            if (isset($item1['_child'])){
                foreach ($item1['_child'] as $key2 => $item2){
                    $permissions[$key1]['_child'][$key2]['own'] = $role->hasPermissionTo($item2['id']) ? 'checked' : false ;
                    if (isset($item2['_child'])){
                        foreach ($item2['_child'] as $key3 => $item3){
                            $permissions[$key1]['_child'][$key2]['_child'][$key3]['own'] = $role->hasPermissionTo($item3['id']) ? 'checked' : false ;
                        }
                    }
                }
            }

        }

        return view('admin.role.permission',compact('role','permissions'));
    }

    /**
     * 更新角色的权限
     * @param Request $request
     * @param $id
     * @return \Illuminate\Http\RedirectResponse
     */
    public function assignPermission(Request $request, $id) {
        $role = Role::findOrFail($id);
        $permissions = $request->get('permissions');
        if(empty($permissions)) {
            $role->permissions()->detach();
            return redirect()->to(route('admin.role'))->with(['status'=>'已更新角色权限1']);
        }else{
            $role->syncPermissions($permissions);
            return redirect()->to(route('admin.role'))->with(['status'=>'已更新角色权限2']);
        }
    }    
    

58.新增上面的模板
/resources/views/admin/role/permission.blade.php

@extends('admin.base')

@section('content')
    
class="layui-card">
        
class="layui-card-header layuiadmin-card-header-auto">
            
class="layui-btn-group ">

                    class="layui-btn layui-btn-sm layui-btn-danger" id="listDelete">删 除


                    class="layui-btn layui-btn-sm" href="{{ route('admin.permission.create') }}">添 加

                class="layui-btn layui-btn-sm" id="returnParent" pid="0">返回上级
            
        
        
class="layui-card-body">
            
            
        
    

@endsection

@section('script')

    

@endsection

59.开发给用户角色和权限，路由添加

// 系统管理
Route::group(['prefix' => 'admin','middleware' => 'auth'],function() {
    //
    // 给人员分配角色
    Route::get('user/{id}/role',[App\Http\Controllers\Admin\UserController::class, 'role'])
        ->name('admin.user.role');
    Route::put('user/{id}/assignRole',[App\Http\Controllers\Admin\UserController::class, 'assignRole'])
        ->name('admin.user.assignRole');
    // 给人员分配权限
    Route::get('user/{id}/permission',[App\Http\Controllers\Admin\UserController::class, 'permission'])
        ->name('admin.user.permission');
    Route::put('user/{id}/assignPermission',[App\Http\Controllers\Admin\UserController::class, 'assignPermission'])
        ->name('admin.user.assignPermission');

});
    

60.添加角色模型
/app/Models/Role.php

namespace App\Models;

class Role extends \Spatie\Permission\Models\Role {

}

61.添加角色关联
/app/Models/User.php
添加 HasRoles,如下

class User extends Authenticatable
{    
    //
    use HasApiTokens, HasFactory, Notifiable, HasRoles;
    //
}

62.控制器添加方法
/app/Http/Controllers/Admin/UserController.php

    /**
     * 获取用户的角色
     * @param Request $request
     * @param $id
     * @return \Illuminate\Contracts\View\Factory|\Illuminate\Contracts\View\View
     */
    public function role(Request $request, $id) {
        $user = User::findOrFail($id);
        $roles = Role::get();
        foreach ($roles as $role) {
            $role->own = $user->hasRole($role) ? true : false;
        }
        return view('admin.user.role',compact('roles','user'));
    }

    /**
     * 处理编辑用户后的角色
     * @param Request $request
     * @param $id
     * @return \Illuminate\Http\RedirectResponse
     */
    public function assignRole(Request $request, $id) {
        $user = User::findOrFail($id);
        $roles = $request->get('roles',[]);
        if($user->syncRoles($roles)) {
            return redirect()->to(route('admin.user'))->with(['status'=>'更新用户角色成功']);
        }
        return redirect()->to(route('admin.user'))->withErrors(['status'=>'系统错误']);

    }

    /**
     * 获取用户拥有的权限
     * @param Request $request
     * @param $id
     * @return \Illuminate\Contracts\View\Factory|\Illuminate\Contracts\View\View
     */
    public function permission(Request $request, $id) {
        $user = User::findOrFail($id);
        $permissions = $this->tree();
        foreach ($permissions as $key1 => $item1){
            $permissions[$key1]['own'] = $user->hasDirectPermission($item1['id']) ? 'checked' : false ;
            if (isset($item1['_child'])){
                foreach ($item1['_child'] as $key2 => $item2){
                    $permissions[$key1]['_child'][$key2]['own'] = $user->hasDirectPermission($item2['id']) ? 'checked' : false ;
                    if (isset($item2['_child'])){
                        foreach ($item2['_child'] as $key3 => $item3){
                            $permissions[$key1]['_child'][$key2]['_child'][$key3]['own'] = $user->hasDirectPermission($item3['id']) ? 'checked' : false ;
                        }
                    }
                }
            }
        }
        return view('admin.user.permission',compact('user','permissions'));
    }

    /**
     * 处理编辑用户的权限
     * @param Request $request
     * @param $id
     * @return \Illuminate\Http\RedirectResponse
     */
    public function assignPermission(Request $request, $id) {
        $user = User::findOrFail($id);
        $permissions = $request->get('permissions');

        if (empty($permissions)){
            $user->permissions()->detach();
            return redirect()->to(route('admin.user'))->with(['status'=>'已更新用户直接权限']);
        }
        $user->syncPermissions($permissions);
        return redirect()->to(route('admin.user'))->with(['status'=>'已更新用户直接权限']);
    }
