However I hope an upcoming manipulator's rewrite will render all this trickiness a thing of the past. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: ManyToManyField not populated in form
That works, great! So should I always use 'manipulator.flatten_data()' instead of 'obj.__dict__' for filling forms with existing values? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

This is why it doesn't work. There is a method in manipulators
'flatten_data' that correctly fills data for ForeignKeys and ManyToMany:
manipulator = Pizza.ChangeManipulator(id) # or whatever you use
new_data = manipulator.flatten_data()

Re: ManyToManyField not populated in form
I'm using manipulators.
==MODELS==
class Pizza(models.Model):
toppings = models.ManyToManyField(Topping)
class Topping(models.Model):
name = models.CharField(maxlength=100)
===
==VIEW=
errors = {}
pizza =
new_data = pizza.__dict__
pizzaFormWrapper = FormWrapper(translatorManipulator, new_data, errors)
return render_to_response('pizza_edit.html', {'pizzaFormWrapper':
pizzaFormWrapper})
==
In the template I'm simply displaying the ManyToMany field in a form:
==TEMPLATE===
Toppings: {{ pizzaFormWrapper.toppings}}
==

What are you using to display the form? Generic view? Manipulators? Drawing "" by hand? A code snippet would be nice... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
