def add(objs : Enumerable(M) | Iterable(M)) #

Adds the given objects to the many-to-many relationship.

If the objects specified in objs are already in the relationship, they will be skipped and not added again.

def add(*objs : M) #

Adds the given objects to the many-to-many relationship.

If the objects specified in objs are already in the relationship, they will be skipped and not added again.
