hi,
how can I create a page similar to the admin pages in the sense of
having a ModelForm and a formset generated with
generic_inline_formset_factory, that is model instances related to my
"base" model with the content_types framework?
I have two models:
class Project(models.Model):
title = models.CharField(max_length=255)
customer = models.ForeignKey(User)
language_from = models.ForeignKey(Language,
related_name='language_from')
language_to = models.ForeignKey(Language,
related_name='language_to')
deadline = models.DateTimeField(null=True)
revenue = models.OneToOneField(Revenue, null=True)
comment = models.TextField(blank=True)
accepted = models.BooleanField(default=False)
closed = models.BooleanField(default=False)
created = models.DateTimeField(auto_now_add=True)
files = generic.GenericRelation('File')
class File(models.Model):
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey()
file = models.FileField(upload_to=get_file_upload_to)
comment = models.TextField(blank=True)
created = models.DateTimeField(auto_now_add=True)
and a form
class ProjectForm(forms.ModelForm):
customer = forms.IntegerField(widget=forms.HiddenInput, initial=0)
class Meta:
model = models.Project
exclude = ['revenue', 'closed', 'accepted']
I can create a form wizard, and add ProjectForm at its first page, and
the following formset at the second
ProjectFilesFormSet = generic_inlineformset_factory(models.File,
exclude=['created'], can_delete=False)
but how can I do it on one page? I'm sure that I miss something, as
ProjectFilesFormSet by default is a subclass of
BaseGenericInlineFormSet, thus it should be possible to be used
"inline".
Can I combine an instance of ProjectFrom and ProjectFilesFormSet on
the same page? Should I do it in the view function by calling first
myProjectForm.save and then ProjectFiledFormSet.save, or is there a
better way?
If so, how can I assure that the ProjectForm won't get written to the
database until the Files are saved?
I know these are quite a few question, and I would be happy to get
answers even to a subset of them.
Thank you, Viktor
