使用laravel中的关系从两个表中获取用户信息

Question

I have model user and user_data. I want to take some data from user and user data. My code looks like:

User model:

public function user_data()
{
    return $this->hasMany('App\Models\UserData', 'user_id');
}

public function getUserById($id)
{
    $user = User::findOrFail($id);

    return $user;
} 

UserData model:

public function user()
{
    return $this->belongsTo('App\User', 'user_id');
}

User controller

public function getUser($id) 
{
    //$user = $this->model->getUserById($id);

    $user = User::with('user_data')->find(3);

    dd($user->sex);
    return view('user', compact('user'));
}

How I can get data from two tables? When i dump sex i get null, but I have it in db.

Answer 1

you have to add also the local key in the relationship like this

public function user_data()
{
    return $this->hasMany('App\Models\UserData', 'user_id','your local key');
}

$user = User::with('user_data')->where('id',$id)->first(); // Get the data like this

After that you can check what is it in like this

$user->user_data[0]->sex // Not $user->sex

If it's not working try to swap the foreign key and local key places.

Also you have to take the data like this
