Question

我正在创建一个CMS应用程序，当然用户需要首先注册或登录。

但是在将数据发送到数据库时遇到了问题。它说'Field 'remember_me' doesn't have a default value'。

我无法找到为什么它需要默认值，因为我发送了remember_me数据，即checked =＆gt; 1和unchecked =＆gt; 0！我正在使用Javascript！

RegisterController.php

<?php

namespace App\Http\Controllers\Authentication;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\User;

class RegisterController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index() {
        return view('auth.register');
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create() {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request) {
        $user = User::create($request->all());

        return redirect('/');
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id) {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id) {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id) {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id) {
        //
    }
}

迁移：

    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('role_id')->default(2);
            $table->integer('is_active')->default(1);
            $table->integer('remember_me');
            $table->string('fname');
            $table->string('lname');
            $table->string('email')->unique();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }

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

请帮我解决一下！

Answer 1

我认为复选框的值应为1，因为当您提交时，即使已经选中它也会为0

<input name="remember_me" id="rememMe" type="checkbox" value="1">

并确保错误再次发生，您可以在控制器中执行此操作

public function store(Request $request) {
    $request['remember_me'] = $request['remember_me'] ? 1 : 0;
    $user = User::create($request->all());

    return redirect('/');
}

希望这会有所帮助

Answer 2

如果在表单中选中了复选框，则会提供on的值，而不是1。数据库中的字段存储integer值，你应该真的使用boolean。这样，Eloquent将接受并存储来自on，off的值，并将其输入为1或0。

以后要防止此错误，您应该在字段中添加默认值，并将其存储为布尔值。

创建新的迁移。

php artisan make:migration add_default_remember_me_to_users

然后在迁移中：

public function up()
{
    Schema::table('users', function($table) {
        // Change field to boolean and define a default value
        $table->boolean('remember_me')->default(0)->change();
    });
}

public function down()
{
    Schema::table('users', function($table) {
        $table->integer('remember_me')->change();
    });

}

然后运行迁移：

php artisan migrate

你应该好好去！
