When rendering a new page, the html form action on that new page is stopping the page from being rendered... even though it has nothing to do with the page itself being rendered (if I remove that one line of HTML code, the page loads just fine). I've been working on solving this problem for over 3 days, tried hundreds of possible solutions, nothing works. Please help
This is the error:

CodePudding user response：
It looks like the url argument new_gallery.id is empty when you render the html template
CodePudding user response：
You need to pass the gallery as context into the view that has the edit form. I don't see in the views that you posted that you have a detail view but I do see a detail view url. So I'm assuming you're passing the edit form to your create view instead? That view doesn't return a context with new_gallery as a context variable. I would create a detail view for your gallery instead and pass the edit form, user and gallery as context to the template.

New context

# Logic
gallery = get_object_or_404(Gallery, pk=gallery_id)
context = {
'form': form,
'username': username,
'new_gallery': gallery,
}
# return an html response with context
Also, when you instantiate an unbound form you should add parenthesis after it.
form = NewGalleryForm()
