Laravel Relationships recursive - php

Question

I have 3 Models:
City:
protected $fillable = [
'name', 'latitude', 'longitude', 'code', 'country_id', 'status', 'weather_code',
];
public function translations() {
return $this->hasMany('App\Models\CityTranslation');
}
public function country() {
return $this->hasMany('App\Models\Country');
}
CityTranslation
protected $fillable = [
'name', 'lang', 'city_id',
];
public function city() {
return $this->hasOne('App\Models\City', 'id', 'city_id');
}
and Country
protected $fillable = [
'code', 'latitude', 'longitude', 'currency_id', 'timezone', 'dam_date', 'status',
];
public function city() {
return $this->hasMany('App\Models\City');
}
My problem is when a go through my CityTranslations and display the city name for the selected language i want also to show information about the city and its country.
There is no problem to call $cityTranslation->city->longitude, but when i call $cityTranslation->city->country->code it gives me a MySQL error:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'countries.city_id' in 'where clause' (SQL: select * from `countries` where `countries`.`city_id` = 4439 and `countries`.`city_id` is not null)
How can I make recursive relations?

Answer 1

Try
$cityTranslation = \App\CityTranslation::with('city.country')->get();
Thats if you want to get all city Translation and it related city and country. The you can loop through and get the country code.
if you want to pick only one city Translation and it related item you can do
$cityTranslation = \App\CityTranslation::with('city.country')->find($id);
Change this (in your city model)
public function country() {
return $this->hasMany('App\Models\Country');
}
to
public function country() {
return $this->belongsTo('App\Models\Country');
}
Because country can have many cities and every city must belong to a country
