管理角色的增删查改
新增角色管理模块，管理角色的增删查改。
新增请求
php artisan make:request Form/RoleForm
文件 RoleForm 代码如下：
<?php
namespace App\Http\Requests;
class RoleForm extends Request
{
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
return [
'name' => 'required',
'display_name' => 'required',
'description' => 'required'
];
}
public function messages()
{
return [
'name.required' => '角色标识不能为空',
'display_name.required' => '角色名称不能为空',
'description.required' => '角色描述不能为空'
];
}
}
新增控制器
php artisan make:controller Backend/RoleController
文件 RoleController.php 代码如下：
<?php
namespace App\Http\Controllers\Backend;
use App\Models\Role;
use App\Http\Requests;
use App\Http\Requests\Form\RoleForm;
use App\Http\Controllers\Controller;
class RoleController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
$roles = Role::paginate(25);
return view('backend.role.index', compact('roles'));
}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
return view('backend.role.create');
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\RoleForm $request
*
* @return \Illuminate\Http\Response
*/
public function store(RoleForm $request)
{
try {
if (Role::create($request->all())) {
return redirect()->route('role.index')->withSuccess('新增角色成功');
}
} catch (\Exception $e) {
return redirect()->back()->withErrors(array('error' => $e->getMessage()))->withInput();
}
}
/**
* Display the specified resource.
*
* @param int $id
*
* @return \Illuminate\Http\Response
*/
public function show($id)
{
return view('backend.role.show', compact('id'));
}
/**
* Show the form for editing the specified resource.
*
* @param int $id
*
* @return \Illuminate\Http\Response
*/
public function edit($id)
{
$role = Role::find($id);
return view('backend.role.edit', compact('role'));
}
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param int $id
*
* @return \Illuminate\Http\Response
*/
public function update(RoleForm $request, $id)
{
$data = $request->all();
unset($data['_token']);
unset($data['_method']);
try {
if (Role::where('id', $id)->update($data)) {
return redirect()->back()->withSuccess('编辑角色成功');
}
} catch (\Exception $e) {
return redirect()->back()->withErrors(array('error' => $e->getMessage()))->withInput();
}
}
/**
* Remove the specified resource from storage.
*
* @param int $id
*
* @return \Illuminate\Http\Response
*/
public function destroy($id)
{
try {
if (Role::destroy($id)) {
return redirect()->back()->withSuccess('删除角色成功');
}
} catch (\Exception $e) {
return redirect()->back()->withErrors(array('error' => $e->getMessage()));
}
}
}

填充数据
打开文件 database/seeds/DatabaseSeeder.php ，修改代码如下：
<?php
use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
use App\Models\User;
use App\Models\Menu;
use App\Models\Role;
class DatabaseSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
Model::unguard();
$this->call(UserTableSeeder::class);
$this->call(MenuTableSeeder::class);
$this->call(RoleTableSeeder::class);
Model::reguard();
}
}
class UserTableSeeder extends Seeder
{
public function run()
{
DB::table('users')->delete();
User::create(['name' => 'Ann', 'email' => 'ann@qq.com', 'password' => bcrypt(123456)]);
User::create(['name' => 'Luis', 'email' => 'luis@qq.com', 'password' => bcrypt(123456)]);
User::create(['name' => 'admin', 'email' => 'admin@qq.com', 'password' => bcrypt(123456)]);
}
}
class MenuTableSeeder extends Seeder
{
public function run()
{
DB::table('menus')->delete();
Menu::create(["parent_id" => "0", "name" => "首页管理", "url" => "index.index", 'description' => '展示系统的各项基础数据']);
Menu::create(["parent_id" => "0", "name" => "菜单管理", "url" => "menu.index", 'description' => '管理菜单的新增、编辑、删除']);
Menu::create(["parent_id" => "2", "name" => "菜单列表", "url" => "menu.index", 'description' => '管理菜单的新增、编辑、删除']);

Menu::create(["parent_id" => "0", "name" => "角色管理", "url" => "role.index", 'description' => '管理角色的新增、编辑、删除']);
Menu::create(["parent_id" => "6", "name" => "角色列表", "url" => "role.index", 'description' => '管理角色的新增、编辑、删除']);
Menu::create(["parent_id" => "6", "name" => "新增角色", "url" => "role.create", 'description' => '新增角色的页面']);
Menu::create(["parent_id" => "6", "name" => "编辑角色", "url" => "role.edit", 'description' => '编辑角色的页面', 'is_hide' => 1]);
Menu::create(["parent_id" => "6", "name" => "角色赋权", "url" => "role.show", 'description' => '编辑角色的页面', 'is_hide' => 1]);
Menu::create(["parent_id" => "0", "name" => "权限管理", "url" => "permission.index", 'description' => '管理权限的新增、编辑、删除']);
Menu::create(["parent_id" => "11", "name" => "权限列表", "url" => "permission.index", 'description' => '管理权限的新增、编辑、删除']);
Menu::create(["parent_id" => "11", "name" => "新增权限", "url" => "permission.create", 'description' => '新增权限的页面']);
Menu::create(["parent_id" => "11", "name" => "编辑权限", "url" => "permission.edit", 'description' => '编辑权限的页面', 'is_hide' => 1]);
Menu::create(["parent_id" => "0", "name" => "用户管理", "url" => "user.index", 'description' => '管理用户的新增、编辑、删除']);
Menu::create(["parent_id" => "15", "name" => "用户列表", "url" => "user.index", 'description' => '管理用户的新增、编辑、删除']);

Menu::create(["parent_id" => "15", "name" => "编辑用户", "url" => "user.edit", 'description' => '编辑用户的页面', 'is_hide' => 1]);
}
}
class RoleTableSeeder extends Seeder{
public function run()
{
DB::table('roles')->delete();
Role::create(['name' => 'admin', 'display_name' => 'User Administrator', 'description' => 'User is allowed to manage and edit other users']);
Role::create(['name' => 'owner', 'display_name' => 'Project Owner', 'description' => 'User is the owner of a given project']);
}
}
