Call to undefined method Illuminate\Database\Query\Builder::saveRelation()

[chancezeus]

When recursively saving my model an error is thrown:

BadMethodCallException Call to undefined method Illuminate\Database\Query\Builder::saveRelation()

The origin of this error is in the saveRelations function at line 795 (version 0.3.1)... The line is: $result = $this->$modelClass()->saveRelation($record);

As far as I understand this tries to call the function "saveRelation" on the relationship defined by "$this->$modelClass()", but this function does not exist. Looking at the laravel API and documentation, there exists a function "save()" which is meant for saving related models (and is similar to associate)...

Any thoughts??

saveRelation is a method within Vocal itself (lines 740 to 745), this could mean the model you're trying to save doesn't extend Vocal but rather extends Eloquents Model class.

Getting the same thing while trying to save a HasOne relationship.

// The important bits of my models
class Party extends Vocal {
    public function organization()
    {
        return $this
            ->hasOne('Organization');
    }

    public function person()
    {
        return $this
            ->hasOne('Person');
    }
}

class Person extends Vocal {
    public function party()
    {
        return $this
            ->belongsTo('Party');
    }
}

class Organization extends Vocal {
    public function party()
    {
        return $this
            ->belongsTo('Party');
    }

}

// then, in the controller...
public function postCreate()
{
    $party = new Party();
    $success = $party->saveRecursive();
    /*
    At this point I get the error:
    BadMethodCallException 
    Call to undefined method Illuminate\Database\Query\Builder::saveRelation()
    */
}

Usually when you get a reference to builder it means there is something happening which uses the query builder instead of eloquent, an example of this would be something like:

Party::where('user_id', 4)->saveRecursive();

In you case have you determined the relationships work correctly? If you do:

$test = Party::with('organization', 'person')->find(1);

Do you get a result with $test->organization and $test->person which aren't ids but are Models?

Are you sure that the index columns don't have the same name as the relationships? E.g the party table doesn't have a column named person which holds the id for the person record? If all of the above works, can you try defining your indexes?

public function person()
{
    return $this
        ->hasOne('Person', 'person_id');
}
