Laravel 11 角色和权限4--编辑角色和删除角色

角色编辑

路由

Route::middleware('auth')->group(function () {
    .
    .
    .
    // 编辑角色页面
    Route::get('/roles/{id}/edit', [RoleController::class, 'edit'])->name('roles.edit');
    // 执行编辑角色
    Route::post('/roles/{id}', [RoleController::class, 'update'])->name('roles.update');
    // 删除角色
    Route::delete('/roles', [RoleController::class, 'destroy'])->name('roles.destroy');
});

控制器 编辑功能

App/Http/Controllers/RoleController.php

// 编辑角色
public function edit($id)
{
    $role = Role::findOrFail($id);
    $hasPermissions = $role->permissions->pluck('name');
    $permissions = Permission::orderBy('name', 'ASC')->get();

    return view('roles.edit', compact('role', 'hasPermissions', 'permissions'));
}

// 执行编辑角色
public function update($id, Request $request)
{
    $role = Role::findOrFail($id);
    $validator = Validator::make($request->all(), [
        'name' => 'required|unique:roles,name,' . $id . ',id',
    ]);

    if ($validator->passes()) {
        $role->name = $request->name;
        $role->save();
        if (!empty($request->permission)) {
            $role->syncPermissions($request->permission);
        } else {
            $role->syncPermissions([]);
        }
        return redirect()->route('roles.index')->with('success', '角色编辑成功~~');
    } else {
        return redirect()->route('roles.edit')->withErrors($validator)->withInput();
    }
}

resources/views/roles/list.blade.php 添加跳转页路由

控制器 删除功能

App/Http/Controllers/RoleController.php

// 删除角色
public function destroy(Request $request)
{
    $id = $request->id;
    $role = Role::find($id);

    if ($role == null) {
        session()->flash('error', '未找到角色~');
        return response()->json([
            'status' => false
        ]);
    }

    $role->delete();
    session()->flash('success', '角色删除成功~');
    return response()->json([
        'status' => true
    ]);
}

前端模版

resources/views/roles/list.blade.php

<a href="javascript:void(0);" onclick="deletePermission( {{$role->id}} )"
   class="bg-red-600 text-sm rounded-md text-white px-3 py-2 hover:bg-red-500">删除</a>

以上：onclick="deletePermission( {{$role->id}} )"，删除按钮绑定。

• 开始书写ajax无刷新删除

<x-slot name="script">
        <script type="text/javascript">
            function deletePermission(id) {
                if (confirm("您确定要删除么~~")) {
                    $.ajax({
                        url: '{{route('roles.destroy')}}',
                        type: 'delete',
                        data: {id: id},
                        dataType: 'json',
                        headers: {
                            'x-csrf-token': '{{ csrf_token() }}'
                        },
                        success: function (response) {
                            window.location.href = '{{ route('roles.index') }}';
                        }
                    });
                }
            }
