用于创建用户的 Laravel 表单无法正常工作

Question

我遇到了一个不起作用的表单。我收到一条错误消息：

SQLSTATE[HY000]：一般错误：1364 字段 firstname 没有 默认值（SQL：插入users (role) 值（用户））。

除了它也没有在数据库中插入数据。请帮忙！！

<?php use Illuminate\Support\Facades\Schema; use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration;class CreateUsersTable extendsMigration{
/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('firstname');
        $table->string('suffix')->nullable();
        $table->string('lastname');
        $table->integer('phoneNumber');
        $table->string('role');
        $table->string('streetName');
        $table->integer('streetNumber');
        $table->string('city');
        $table->string('zipcode');
        $table->string('email')->unique();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });
}

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::dropIfExists('users');
}

}

我的表格：

{!! Form::open(['method'=>'POST', 'action'=>'UsersAdminController@store']) !!}
        @csrf

        <div class="form-group row">
            {!! Form::label('firstname', 'First name:') !!}
            {!! Form::text('firstname', null, ['class'=>'form-control']) !!}
        </div>

        <div class="form-group row">
            {!! Form::label('suffix', 'Suffix:') !!}
            {!! Form::text('suffix', null, ['class'=>'form-control']) !!}
        </div>

        <div class="form-group row">
            {!! Form::label('lastname', 'Last name:') !!}
            {!! Form::text('lastname', null, ['class'=>'form-control']) !!}
        </div>

        <div class="form-group row">
            {!! Form::label('city', 'City:') !!}
            {!! Form::text('city', null, ['class'=>'form-control']) !!}
        </div>

        <div class="form-group row">
            {!! Form::label('zipcode', 'Zipcode:') !!}
            {!! Form::text('zipcode', null, ['class'=>'form-control']) !!}
        </div>

        <div class="form-group row">
            {!! Form::label('phoneNumber', 'Phone number:') !!}
            {!! Form::number('phoneNumber', null, ['class'=>'form-control']) !!}
        </div>

        <div class="form-group row">
            {!! Form::label('streetName', 'Street name:') !!}
            {!! Form::text('streetName', null, ['class'=>'form-control']) !!}
        </div>

        <div class="form-group row">
            {!! Form::label('streetNumber', 'Street number:') !!}
            {!! Form::number('streetNumber', null, ['class'=>'form-control']) !!}
        </div>

        <div class="form-group row">
            {!! Form::label('email', 'E-mail:') !!}
            {!! Form::email('email', null, ['class'=>'form-control']) !!}
        </div>

        <div class="form-group row">
            {!! Form::label('password', 'Password:') !!}
            {!! Form::password('password', ['class'=>'form-control']) !!}
        </div>

        <div class="form-group row mb-0">
            <div class="col-md-6 offset-md-4">
               {!! Form::submit('Create User', ['class'=>'btn btn-primary']) !!}
            </div>
        </div>

    {!! Form::close() !!}

和我的控制器：

public function store(UsersRequest $request)
{
    if(trim($request->password) == '')
    {
        $input = $request->except('password');

    }else{

        $input = $request->all();
        $input['password'] = bcrypt($request->password);
//$input['role'] = 'user';

        DB::table('users')->insert(
            ['role' => 'user']
        );

    }

    User::create($input);

    return back()->with('success' , 'User is succesfully created');

}

这是我在请求文件中的验证：

class UsersRequest extends FormRequest
{
/**
 * 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 [

        'firstname' => 'required',
        'suffix' => 'string',
        'lastname' => 'required',
        'phoneNumber' => 'required',
        'streetName' => 'required',
        'streetNumber' => 'required',
        'city' => 'required',
        'zipcode' => 'required',
        'email' => 'required',
        'password' => 'required',
    ];
}
}

这也是我的用户模型批量分配：

protected $fillable = [
    'firstname','suffix','lastname', 'phoneNumber', 'role', 'streetName', 'streetNumber', 'city', 'zipcode' ,'email', 'password',
];

Answer 1

您必须在名字列中插入一个值。您可以使用与角色列相同的方式执行此操作，只需扩展您的数组：

DB::table('users')->insert([
    'role' => 'user',
    'firstname' => 'The First Name',
]);

firstname 列也没有标记为 ->nullable()，因此当您在该表中插入一行时，它总是需要一个值。

Answer 2

**replace this method with your controller**

public function store(UsersRequest $request)
{

        $input = $request->all();
        $input['password'] = bcrypt($request->password);
        $input['role'] = 'user';

        User::create($input);

        return back()->with('success' , 'User is succesfully created');
}

然后替换

protected $fillable = [
    'firstname','suffix','lastname', 'phoneNumber', 'role', 'streetName', 'streetNumber', 'city', 'zipcode' ,'email', 'password',
];

to 

 protected $guarded = [];

Answer 3

用你的控制器替换它：

public function store(UsersRequest $request)
{
    if(trim($request->password) == '')
    {
        $input = $request->except('password');

    }else{

        $input = $request->all();
    }
    $input['password'] = bcrypt($request->password);
    $input['role'] = 'user';

    User::create($input);

    return back()->with('success' , 'User is succesfully created');
}

Answer 4

这不是将所有数据插入数据库的正确方法，而是如下更新您的控制器并检查它。

    public function store(UsersRequest $request){
    $user= New User([
            'firstname'         => $request->get('firstname'),
            'suffix'            => $request->get('suffix'),
            'lastname'          => $request->get('lastname'),
            'phoneNumber'       => $request->get('phoneNumber'),
            'role'              => $request->get('role'),
            'streetName'        => $request->get('streetName'),
            'city'              => $request->get('city'),
            'zipcode'           => $request->get('zipcode'),
            'email'             => $request->get('email'),
            'email_verified_at' => $request->get('email_verified_at'),
            'password'          => Hash::make($data['password']),
        ]);

        $user->save();

        return back()->with('success' , 'User is succesfully created');

        }

}

如果要使用，请添加验证。另外，请确保您的数据库已连接检查 .env 文件。
