Laravel Cities relation foreign key - php

Question

Im really new to laravel, and im sure im doing something wrong
I have 2 tables. Cities And users_metadata
My cities table look like this
id | City |
1 | New York |
1 | Los Angeles |
users metadata
user_id | firt name | last name | cities_id |
1 | Jonh | Doe | 2 |
So my problem is when i create a relation i get New York, becaus the city id is matched with the user id
City model
class City extends Eloquent
{
public static $table = "cities";
public function profile()
{
return static::has_many('Profile');
}
}
profile model
class Profile extends Eloquent
{
public static $timestamps = false;
public static $table = "users_metadata";
public static $key = "user_id";
public function city()
{
return static::has_one('City');
}
}
error
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'profile_id' in 'where clause'
SQL: SELECT * FROM `cities` WHERE `profile_id` = ? LIMIT 1
Bindings: array (
0 => 1,
)
If i dont pass the id to has one i get the following error
Okay i understand this.
So my questions is am i able to pass the foreign key cities_id somehow in my relation to match? Or im doing it all wrong? Can someone give me a basic example?
thank you folks

Answer 1

Try this:
City model
class City extends Eloquent
{
public static $table = "cities";
public function profile()
}
Profile model
class Profile extends Eloquent
{
public static $timestamps = false;
public static $table = "users_metadata";
public static $key = "user_id";
public function city()
{
return static::belongs_to('City');
}
}
I ran into the same problem thinking I should use has_one, but I needed to use belongs_to. user1808639's probably didn't work because you still had a 'has_many' in the city model.

Try this:
class Profile extends Eloquent
{
public function city()
{
return $this->belongs_to('City'); // city_id in the table
}
}

Laravel has a way of detecting foreign keys automatically. So for your database schema... this models should work fine
Try the following
user_id | firt name | last name | city_id | //city not cities
1 | Jonh | Doe | 2 |
-
class Profile extends Eloquent
{
public static $timestamps = false;
public static $table = "users_metadata";
public function city()
{
return $this->has_one('City');
}
}
/
class City extends Eloquent
{
public static $timestamps = false;
public function profiles()
{
return $this->has_many('Profile');
}
}

The table rows shouldn't contain whitespaces. So rename "firt name" | "last name" in "firstname" | "lastname". The SQL-error shows me that you're calling the model in the reverse way like City::find(1) in this case Laravel expects inside the "Cities" table the foreign key for the profiles that would be usually "profile_id".
I guess you're looking for something like this:
$user_id = 1;
$user = Profile::find($user_id);
echo $user->firstname." ".$user->lastname." lives in ".$user->city->city;
