Using make_recipe with _quantity together with related key only applies to last item created

Using make_recipe with _quantity together with related key only applies to last item created

Given this setup code:

mommy_recipes.py:

dog1 = recipe.Recipe(
     Dog
)

dog2 = recipe.Recipe(
    Dog
)

company = recipe.Recipe(
    Company
)

incomplete_person = recipe.Recipe(
    Person,
    dog_set=recipe.related(dog1, dog2)
)

complete_person = incomplete_person.extend(
    company=recipe.foreign_key(company)
)

In a test python file:

people = mommy.make_recipe("complete_person", _quantity=3)

Expected behavior

That each model in people has the 2 dog instances.

Actual behavior

Only the last item in people has the 2 dog instances. The first 2 are empty.

Reproduction Steps

I was able to work around this by calling mommy.make_recipe("complete_person") in a list comprehension, but it's a bug if I use the _quantity keyword

Declaring a kwargs that holds the attrs that transcend one recipe seems a more flexible workaround.

# dog1, dog2, and company as above

person_kwargs={
    'dog_set': recipe.related(dog1, dog2)
)

unemployed_person = Recipe(Person,
    **person_kwargs
)

employed_person = Recipe(Person, 
    company=recipe.foreign_key(company)
    **person_kwargs
)

NOTE: I also reject the notion that you need a company to be complete ;).

Then extend doesn't truly extend in all cases. You have to explicitly remember these type of arguments and explicitly specify them each time? That should at least be documented, but it would be nice to have it fixed.

@urbnjamesmi1, yes it is a bug that should be fixed, but wanted to share a possibly useful workaround.
