ManyToMany relation with a through model using factory_boy? - django

Question

I'm facing the problem when creating the many to many relation with through model using factory. I followed this link factory recipies.
I'm getting the TypeError: 'datetime.date' object is not callable this error. Help me to find the solution.
I got an another error:

In this line:
start_date = factory.LazyAttribute(datetime.today)
You need to actually call the function with ():
start_date = factory.LazyAttribute(datetime.today())
