Re: CBV with inline formset

2014-12-15 Thread Brad Rice 
Thanks. I think I figured out how to do this with a straight createView.

class BookCreate(CreateView):
model = Book
form_class = BookForm
template_name = 'book_template.html'
success_url = u'/dp/thanks'

def get(self, request, *args, **kwargs):
self.object = None
form_class = self.get_form_class()
author = Author.objects.get(id=self.kwargs['author_id'])
formset = BookFormset(instance=author)
return self.render_to_response(self.get_context_data(formset=formset))

def post(self, request, *args, **kwargs):
self.object = None
form_class = self.get_form_class()
author = Author.objects.get(id=self.kwargs['author_id'])
formset = BookFormset(request.POST,request.FILES,instance=author)
if formset.is_valid():
formset.save()
return HttpResponseRedirect(reverse('dp:thanks'))

def form_valid(self, formset):
context = self.get_context_data()
book_formset = context['formset']
if book_formset.is_valid():
# self.object = book_formset.save()
book_formset.instance = self.object
book_formset.save()
return HttpResponseRedirect(self.get_success_url())
else:
return 
self.render_to_response(self.get_context_data(formset=book_formset))

Re: CBV with inline formset

2014-12-15 Thread Dan Gentry 
I created a couple of mixins for a project that might help you.  See this 
gist: https://gist.github.com/dashdrum/03858d79ddfd9bba44d6

Pretty easy to use.  Here's an example Create view:

class RegistrationView(FormsetCreateMixin,CreateView):
template_name = 'registration/registration_form.html'
model = RegistrationMaster
form_class = RegistrationForm
detail_form_class = RegDetailFormSet


The mixin creates a new class variable: detail_form_class.  Set this in the 
view class declaration to point to your formset.  

I haven't tested this beyond the one project, so please tread carefully.  I 
hope this can at least get you moving in the right direction.

CBV with inline formset

2014-12-15 Thread Brad Rice 
I've pretty much butchered the code for 3 days now and cannot figure out 
how to insert an inline formset. Can anybody help me?

I've tried to pare everything down to use two simple Models just to try to 
get an insert. I'm using django Author - Book relationship to keep it 
simple.

class Author(models.Model):
name = models.CharField(max_length=100)

def __unicode__(self):  # __unicode__ on Python 2
return self.name


class Book(models.Model):
name = models.CharField(max_length=100)
author = models.ForeignKey(Author)

So I have a page where you can insert and author. The author page takes you 
to a page to insert books for that author using an inline formset of 3 
books.

In my urls.py I have this url url(r'^book_create/(?P\d+)/$', 
BookCreate.as_view(), name='book_create'),

When you go to book_create I can see the author_id getting passed in the 
kwargs. Now how to I insert from there books into the db with the Foreign 
Key to that author passed in the kwargs?

After banging away for so long, I decided to try to switch to django extra 
views. this is what I have in my views.py

class BookCreate(InlineFormSetView):
model = Author
inline_model = Book
form_class = BookForm
extra = 3
template_name = 'book_template.html'

def get_queryset(self):
slug = self.kwargs['author_id']
return super(BookCreate, self).get_queryset().filter(id=slug)

When I go to the book_create page I get this error:

Generic detail view BookCreate must be called with either an object pk or a 
slug.
