Question

你好，我尝试在laravel 5.8中创建注册，但是当我尝试注册时出现此错误：

tableuser.php

 public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('username')->unique();
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->boolean('admin')->default(false);
            $table->rememberToken();
            $table->timestamps();
        });
    }

registe.blade.php

SQLSTATE [HY000]：常规错误：1364字段“用户名”没有默认值（SQL：插入users（name，email，password， updated_at，created_at）值（denden73，denden73@gmail.com， $ 2y $ 10 $ x.J7316.UH.UFnzZaeI5F.TTXkYyd.xVUlrjV6EoHA7J88R0X9Ode， 2019-07-25 12:50:54，2019-07-25 12:50:54））

Answer 1

尝试将其添加到您的User.php模型文件中

protected fillable = ['username', 'email', 'password'];

Answer 2

请检查您是否遵循以下步骤。

1）迁移时使用nullable（）。

setStyleSheet()

2）可填充到您的模型中。

$table->string('username')->nullable();

3）在创建新用户时提及用户名。

protected $fillable = [
    'username', 'name', 'email','password','admin'
];

Answer 3

您的插入查询，例如：

DB::table('users')->insert(array('username'=>$request->username,'name'=>$request->name,'email'=>$request->email,'password'=>$request->password));
