Question

Referring to django-autofixture documentation, I wrote the following code (edited for terseness):

    def random_state_generator(self, states=None): 
        import random
        if not states: 
            states = "waiting|email|post|einv".split('|')
        while 1: 
            yield random.choice(states)

…

   rsg = self.random_state_generator()
   self.create_test_foo(10, values={'state': rsg})

…

    field_values = dict(field_values.items() + values.items())
    foo_fixture = AutoFixture(FooClass, overwrite_defaults=True, 
                              generate_fk=generate_fk_values,
                              field_values=field_values)
    bunch_of_stuff = foo_fixture.create(foo_count)

Okay,
now when I have the DB all set up, and I filter myself a list of stuff,
and go

for foo in bunch_of_stuff: print (foo.state)

instead of getting the expected random state string, I get the following output:

generator object random_state_generator at 0x242c640>

which is not what I’d expect based on the documentation, specifically

field_values: A dictionary with field names of model as keys. Values may be static values that are assigned to the field, a Generator instance that generates a value on the fly or a callable which takes no arguments and returns the wanted value.

What am I doing wrong?

Answer 1

Okay, the field_values takes a class instance from autofixture.generators, so all I had to do was:
generate the list of states;

from autofixture.generators import ChoicesGenerator
states = "waiting|email|post|einv".split('|')
rsg = ChoicesGenerator(values=states)
self.create_test_foo(10, values={'state': rsg})

the misunderstanding rose from confusing autofixture’s generators with generic python generators.
