Planning model for a survey application


Hi all,

I'm planning how to design a model to be used in a survey application.
The casic idea is to have some surveys made of questions.
I'm not sure about the best choice betweem:

a) define Survey class with no foreign key in it and define Question
class with a ManyToManyField pointing to Survey

class Survey(models.Model):
title
author

class Question(models.Model):
text
surveys = ManyToManyField

b) Put ehe ManyToMany Field in the Survey class definition

class Survey(models.Model):
title
author
questions = ManyToManyField

class Question(models.Model):
text

What is the best choice for you? I'm guessing that there is no
different. Only in the later use of django commands like:

a) s=Survey()
s.question_set.all()
q=Question()
q.surveys.all()

b) s=Survey()
b.questions.all()

Thanks in advance !
