Retrive data based on pivot table in laravel - database

Question

I have those tables in my database
Translation
id
translation_key_id
content
Language
id
code (it would be "eng" or "ger" or "fre")
translation_language
id
translation_id
language_id
Now the models are
class Language extends Eloquent {
protected $fillable = array('id','code');
protected $table = 'language';
private $rules = array();
public function translation()
{
return $this->belongsToMany('translation','language_translation');
}
}
class Translation extends Eloquent {
protected $fillable = array();
protected $table = 'translation';
private $rules = array();
public function language()
{
return $this->belongsToMany('language','language_translation');
}
}
Now i want to retrieve those data which have transkation_key_id = abc (as for example ) and also with code = "eng"
How can i do that?

Answer 1

First of all I don't see the need for pivot table here.
Show me why you need that, or change your relation to belongsTo. You can link translation with language using id (1) or code (2), which is unique obviously, right? So here it goes:
table translations: id, key, content, language_id (or language_code)
// Translation
public function language()
{
// option 1
return $this->belongsTo('Lanugage');
// or 2:
// return $this->belongsTo('Lanugage', 'language_code', 'code');
}t
then
// option 1
Translation::where('key', 'whatever')->whereHas('language', function ($q) {
$q->where('code', 'eng');
})->first();
// option 2, even easier w/o any join needed
Translation::where('key', 'whatever')->where('language_code', 'eng')->first();

Answer 2

You've built relationships incorrect
try this
class Language extends Eloquent {
protected $fillable = array('id','code');
protected $table = 'language';
private $rules = array();
public function translation()
{
return $this->belongsToMany('Translation','translation_language');
}
}
class Translation extends Eloquent {
protected $fillable = array();
protected $table = 'translation';
private $rules = array();
public function language()
{
return $this->belongsToMany('Language','translation_language');
}
}
