Unable to Get Eloquent to Automatically Create Joins

Clearly with('Country') or with('country') doesn't do any different due to the fact that he managed to get following error:

Column not found: 1054 Unknown column 'tournament_id' in 'where clause'SQL: SELECT * FROM `countries` WHERE `tournament_id` IN (?)

What wrong is how the relationship is defined: A tournament must have a country would be a tournament need to belong to a country, and not has one country. So to solve this change the relationship to

public function country(){    return $this->belongs_to('Country');}

According to the Eloquent docs:

Note: All methods available on the query builder are also available when querying Eloquent models.

So with that in mind something like:

DB::table("tournament")->join("countries","tournaments.country_id","=","countries.id")->get();

Should be replicable in Eloquent. I personally use the query builder version just now which you may want to use but I will try and test with Eloquent when I get the chance and update this.

UPDATE:

Yep, using Eloquent's query builder methods you can have:

Tournament::join("countries","tournaments.country_id","=","countries.id")->get();

This will return a Tournament model that includes the fields of both tables.

HTH

Your 'with' clause asks for 'Country', but your code declares it as 'country'.

So, should:

$tournaments = Tournament::with('Country')->all();

Be:

$tournaments = Tournament::with('country')->all();

Because in your Tournaments Model, you've defined this as:

public function country(){    return $this->has_one('Country');}

Does making this change solve it?
