我添加了一个 foreignKey 列来为用户指定一个角色。这是用户表:在我将nullable()添加到role_id列之前,他们被告知role_id列没有默认值,当我添加nullable()时,他们将 NULL 值插入到表中

Schema::create('users', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->string('phone_number')->unique();
    $table->string('email')->unique()->nullable();
    $table->timestamp('email_verified_at')->nullable();
    $table->string('password');
    $table->integer('role_id')->unsigned()->nullable();
    $table->rememberToken();
    $table->timestamps();
    $table->foreign('role_id')->references('id')->on('roles')->onDelete('cascade');
});

这是角色表:

Schema::create('roles', function (Blueprint $table) {
    $table->increments('id');
    $table->string('type');
    $table->timestamps();
});

这是角色列的刀片代码: 我在刀片上添加了一个数组,以在属性名称为“ role_id ”的选项标签中显示其内容,正如您在刀片代码中看到的那样

@php
    $role_array = ['employee', 'client'];
@endphp

<div class="form-group row">
    <label for="role" class="col-md-4 col-form-label text-md-right">Role <span class="text-danger">*</span></label>
    <div class="col-md-6">
        <select id="role" name="role_id" class=" form-control">
            <option selected>Choose...</option>
            @foreach ($role_array as $x => $x_value)
                 <option value="{{++$x}}">{{$x_value}}</option>
            @endforeach
        </select>
    </div>
</div>

这是“ CreateNewUser.php ”文件的创建方法:

    public function create(array $input)
    {
        Validator::make($input, [
            'name' => ['required', 'string', 'max:255'],
            'email' => [
                'string',
                'email',
                'max:255',
                Rule::unique(User::class),
            ],
            'phone_number' => [
                'required',
                'string',
                'min:10',
                'max:13',
                Rule::unique(User::class),
            ],
            'role_id' => [
                'required',
                Rule::unique(User::class),
            ],
            'password' => $this->passwordRules(),

        ])->validate();

        return User::create([
            'name' => $input['name'],
            'email' => $input['email'],
            'phone_number' => $input['phone_number'],
            'password' => Hash::make($input['password']),
        ]);
    }

这是用户模型:

   protected $fillable = [
        'name',
        'password',
        'phone_number',
        'email',
        'role_id',
    ];

你必须通过role_id创建方法

   return User::create([
            'name' => $input['name'],
            'email' => $input['email'],
            'phone_number' => $input['phone_number'],
            'password' => Hash::make($input['password']),
            'role_id' => $input['role_id'],
        ]);

也适用于控制器中的角色

$role_array=Role::pluck('type','id');

然后在视野中

<select id="role" name="role_id" class=" form-control">
            <option selected>Choose...</option>
            @foreach ($role_array as $x => $x_value)
                 <option value="{{$x}}">{{$x_value}}</option>
            @endforeach
        </select>
