See the Laravel documentation here: http://laravel.com/docs/eloquent#inserting-related-models

Basically you have set up two different types of relationships for the same two tables - you've set up a many-to-many and a one-to-many. It looks as though you probably wanted a many-to-many, so you'll need to change this line:

return $this->hasMany('Atividade');

To this:

return $this->belongsToMany('Atividade');

This will set the relationship up as a many-to-many relationship, which will then support the attach() method.

The attach() method is only for many-to-many, for other relationships there's save() or saveMany() and associate() (see the docs linked above).
