Laravel 5:SQLSTATE[23000]:违反完整性约束
Laravel 5: SQLSTATE[23000]: Integrity constraint violation
我有一个包含以下字段的表单:姓名、全名、描述、电子邮件、密码、州、城市(选择州时通过 Ajax 填写)和照片(图片上传)。
这是我的架构:
public function up()
{
Schema::create('states', function(Blueprint $table)
{
$table->increments('id');
$table->string('acronym');
$table->string('name');
});
Schema::create('cities', function(Blueprint $table)
{
$table->increments('id');
$table->string('name');
$table->integer('state_id')->unsigned();
$table->foreign('state_id')->references('id')->on('states');
});
Schema::create('users', function(Blueprint $table)
{
$table->increments('id');
$table->string('name');
$table->string('fullname');
$table->string('photo');
$table->text('description');
$table->string('email');
$table->string('password', 60);
$table->integer('city_id')->unsigned();
$table->foreign('city_id')->references('id')->on('cities');
$table->rememberToken();
});
}
我的问题是,当我按下提交按钮时,出现以下错误信息:
SQLSTATE[23000]:违反完整性约束:1452 无法添加或更新子行:外键约束失败(yearbook
.users
,CONSTRAINT users_city_id_foreign
FOREIGN KEY (city_id
) REFERENCES cities
(id
)) (SQL: insert into users
(name
, description
, email
) 值(加布里埃尔,描述,电子邮件@gmail.com))
所以问题与 city_id 作为外键有关(表单选项中的 'value' 属性是 id)。例如:
<option value="281">Abaíra</option>
但是当我尝试通过 phpmyadmin 插入时,它插入没有错误。
那么可能是什么问题?
这是我在控制器上的保存方法:
public function saveRegister()
{
$rules = array(
'name' => 'required',
'description' => 'required',
'fullname' => 'required',
'email' => 'required',
'password' => 'required',
'state' => 'required',
'city' => 'required',
'photo' => 'required',
'photo' => 'image|max:3000000',
);
$val = \Validator::make(\Input::all(), $rules);
if($validar->fails()){
return redirect('register')->withErrors($val);
} else {
$user = new User(array(
'name' => \Input::get('name'),
'description' => \Input::get('description'),
'fullname' => \Input::get('fullname'),
'email' => \Input::get('email'),
'city_id' => \Input::get('city'),
));
$user->timestamps = false;
$user->save();
return redirect('register')->with('message', 'User saved!');
}
}
编辑:在 saveRegister() 方法中修复了 city_id。
可能是因为您的 cities.id 字段未签名,而您的 FK 字段未签名。关系中使用的所有列必须完全匹配。
尝试将您的代码更改为:
Schema::create('cities', function(Blueprint $table)
{
$table->increments('id')->unsigned();
而不是
$user = new User(array(
'name' => \Input::get('name'),
'description' => \Input::get('description'),
'fullname' => \Input::get('fullname'),
'email' => \Input::get('email'),
'city' => \Input::get('city'),
));
这样做
$user = new User();
$user->fill(array(
'name' => \Input::get('name'),
'description' => \Input::get('description'),
'email' => \Input::get('email')
));
$user->fullname = \Input::get('fullname');
$user->city= \Input::get('city');
或更改模型中的$fillable
属性
