django inline formsets with a complex model for the nested form

Question

Say I have django model that looks something like this:

class Order(models.Model):
 number = models...
 date = models...

class OrderLine(models.Model):
 # O         


        

Answer 1

I solved problem with http://yergler.net/blog/2009/09/27/nested-formsets-with-django/. Pleas use the following correction in forms.py file:

        instance=None
            pk_value = hash(form.prefix)

+       correct_data = None
+       if (self.data):
+           correct_data = self.data;
        # store the formset in the .nested property
        form.nested = [
-           TenantFormset(data=self.data,
+           TenantFormset(data=correct_data,
                            instance = instance,

Just working on Django 1.4.1 very well.
