我使用PHP,Laravel 5.2和MySQL。
在用户注册期间,我需要创建一个新患者。但是,患者有用户ID,联系人ID和监护人ID(外键)。
当我尝试保存()患者时,我得到以下例外:
SQLSTATE [42S22]:未找到列:1054未知列' patient_id'在 '字段列表' (SQL:update
users
setpatient_id
= 0,updated_at
= 2016-06-07 12:59:35其中id
= 6)
问题是我没有 patient_id 专栏。相反,我有 patientId 。
我不知道如何解决这个问题。任何帮助将不胜感激。如果这很重要,我可以包含迁移文件。
UserController.php
public function postSignUp(Request $request)
{
$this->validate($request,[
'email' => 'required|email|unique:users',
'name' => 'required|max:100',
'password' => 'required|min:6'
]);
$guardian = new Guardian();
$guardian->guardianId = Uuid::generate();;
$guardian->save();
$contact = new Contact();
$contact->contactId = Uuid::generate();
$contact->save();
$user = new User();
$user->email = $request['email'];
$user->name = $request['name'];
$user->password = bcrypt($request['password']);
$user->save();
$patient = new Patient();
$patient->patientId = (string)Uuid::generate();
$patient->user()->save($user);
$patient->contact()->save($contact);
$patient->guardian()->save(guardian);
$patient->save();
Auth::login($user);
// return redirect()->route('dashboard');
}
Patient.php
class Patient extends Model
{
protected $primaryKey='patientId';
public $incrementing = 'false';
public $timestamps = true;
public function user()
{
return $this->hasOne('App\User');
}
public function contact()
{
return $this->hasOne('App\Contact');
}
public function guardian()
{
return $this->hasOne('App\Guardian');
}
public function allergies()
{
return $this->belongsToMany('App\PatientToAllergyAlert');
}
public function medicalAlerts()
{
return $this->belongsToMany('App\PatientToMedicalAlert');
}
}
user.php的
class User extends Authenticatable
{
protected $fillable = [
'name', 'email', 'password',
];
protected $hidden = [
'password', 'remember_token',
];
public function patient()
{
return $this->belongsTo('App\Patient');
}
}
Contact.php
class Contact extends Model
{
protected $table = 'contacts';
protected $primaryKey = 'contactId';
public $timestamps = true;
public $incrementing = 'false';
public function contact()
{
return $this->belongsTo('App\Patient');
}
}
Guardian.php
class Guardian extends Model
{
protected $table = 'guardians';
protected $primaryKey = 'guardianId';
public $timestamps = true;
public $incrementing = 'false';
public function contact()
{
return $this->belongsTo('App\Patient');
}
}

您尚未正确定义关系。首先,将表字段填入Patient,Contact,Guardian类中的$ fillable数组中(就像在User类中一样)。
如果您想在患者和用户之间使用hasOne关系,那么您需要患者表上的user_id字段。您也可以使用belongsTo关系。
如果要使用自定义列名称,只需在关系方法中指定它们:
public function user()
{
return $this->hasOne('App\User', 'id', 'user_id');
// alternatively
return $this->belongsTo('App\User', 'user_id', 'id');
}
只需浏览文档而不跳过段落,您将在几分钟内完成:) https://laravel.com/docs/5.1/eloquent-relationships#defining-relationships
此外,这不起作用:
$patient = new Patient();
$patient->patientId = (string)Uuid::generate();
$patient->user()->save($user);
new Patient()仅创建对象,但不将其存储在DB中,因此您将无法保存关系。您需要创建对象并将其存储到DB以避免此问题:
$patient = Patient::create(['patientId' => (string)Uuid::generate()]);
$patient->user()->save($user);
...
// or
$patient = new Patient();
$patient->patientId = (string)Uuid::generate();
$patient->save();
$patient->user()->save($user);
...

设置关系时,可以在其他模型中指定主键的名称。看here。
我不确定,但我认为您的关系定义不正确。
