1) Use a ModelForm, which would do this for you. [1] 2) M2Ms aren't created when you create the initial instance of an object, you must first create the object, and then relate it. Semantically, creating an M2M link between two objects is creating a row in a links table between them, with the row containing the primary key of one object and the primary key of the other object. Therefore, both objects must exist in the database before you can link them, and your question is simply "How do I create an M2M link between two objects", which is well answered in the docs [2].
