I am just starting with ORM. I had a question, this is my tabel --
table a - (aid, aname, atag);
table b - (bid, aid, bname, .. );
It is One to Many relationship - that is One aid can belong to many bid but one bid can belong to only one aid .
So I was trying out this code, In the out put I want -- (bname,aname) for all the records.
A model --
class A extends Eloquent {
protected $table = 'a';
protected $primaryKey = 'aid';
public function brelation() {
$this->belongsToMany('B','aid');
}
}
B model --
class B extends Eloquent {
protected $table = 'b';
protected $primaryKey = 'bid';
public function getANames() {
$this->hasOne('A','aid');
}
}
In Controller --
foreach(B::with('getANames')->get() as $b_item){
echo $b_item->bname." , ".$b_item->aname;
}
Couple of points to clarify --
1) I have to specify the foreign key to make sure they map. Because in my actual case they are named differently.
2) I am using Laravel 4.
Can someone show me what I did wrong and how I can get the desired result.
===== Update =====
class A extends Eloquent {
protected $table = 'a';
protected $primaryKey = 'aid';
public function brelation() {
$this->belongsTo('B','aid');
}
}
I still cannot access the aname column ie ($b_item->aname) in the controller.
A couple of things you should be aware of:
If you have a custom primary key, you need to set the $primaryKey property on your eloquent models to the primary keys you have in the DB.
You can't mix and match belongsToMany
relationships with anything other than belongsToMany
s. A belongsToMany
is exclusively for the case where you have two tables that are connected by a pivot table. In your case, B belongsTo
A, and A hasMany
B.
