How to Programming with Django-views

django,django-models,django-forms,django-views

If you look at the full traceback, you should be able to see that it is not the LampCreateView that is raising the exception. It sounds like you have another url pattern above the lamp_create which matches /shotmaker/camera/create/ first. For example: url(r'^camera/(?P<pk>[-\w]+)/$', views.OtherView.as_view(), name='other_view') url(r'^camera/create/(?P<pk>[-\w]+)$', views.LampCreateView.as_view(), name='lamp_create'), To solve the...

How to submit POST request to '“current_url”/submit' in HTML's form action using Django templates?

django,django-templates,django-views,html-form

It's a bad idea to try and parse/modify the existing URL. But there's no reason to. Your template presumably already has access to the post itself, so you should use this to construct the URL via the normal {% url %} tag. <form action="{% url "submit_comment" post_id=post.id %}" method="POST"> assuming...

Why I get MultiValueDictKeyError in django?

You're missing the enctype="multipart/form-data" in the HTML form tag. Otherwise no file data is sent by the browser. Nevertheless, you should not be referencing the request.POST and request.FILES dicts directly in your view: that's what the form is for: dform = ArticleForm(request.POST, request.FILES) if dform.is_valid(): article = dform.save(commit=False) article.user =...

DjangoRestFramework - registering a user: difference between UserSerializer.save() and User.objects.create_user()?

Neither of those is perfect. But View A looks promising. View A is a good start, but it is incomplete solution. Because User creation is not simply User.save, but rather you have to call User.create_user method. View B is the correct way to create user by calling User.create_user, however, the...

Django: form to query database

django,django-forms,django-templates,django-views,django-queryset

The issue lies at that line: cart_item = CartItem.objects.create(cart=cart, product=product) The create method expects product to be a Product instance, you are passing a string (u'2').
