I\'m currently having problems with a n:n relationship with Laravel 4, I\'m having an error wiht pivot table which is quering on a table with with both components on singula
The pivot table should be singular version of the table names it is linking, in alphabetical order so in your case:
land_obj rather than lands_objs
If you really don't want to use the default naming conventions you can also specify the table name as the 2nd param on the belongsToMany call in your models:
return $this->belongsToMany('Obj', 'lands_objs');
and
return $this->belongsToMany('Land', 'lands_objs');
