django-forms

问题 When I try to save my inline formset it just returns an empty list and no changes are reflected in the database. I have tried doing it with no option and commit=False but they both have the same result. I know there is data because I printed the formset as a table, and I know it is valid because the property is_valid() method returns true. Here is the code: def edit(request): if request.method == 'POST': print(request.POST) form = TombstoneForm(request.POST) print(form.is_valid()) t = form

问题 I'm looking into Python/Django to evaluate suitable e-commerce solution. For now Satchmo package seems to deliver solution to satfy most of my needs with Subscription product type. However, I still have home requirements to meet and I ended wondering that is Satchmo or some other cart/commerce package suitable for personalized products? I need the user to fill in some "personal details" regarding Subscription since Subscription products/orders can be assigned to other users and/or to non-user

问题 I want to create a search box in Django that is situated at the URL /search, and redirects to a friendly URL like /search/queryterm - rather than having ?q=queryterm in the URL) So the user types in a query term, it takes them to /search/queryterm, and shows a list of results. I can get and display the results OK given a URL like /search/queryterm. But I don't know the best way to handle the URL redirect from the form. Should this be a redirect in pure HTML in the form (which feels slightly

问题 I have an UpdateView that will display a form to either create the user profile or update the user profile. It works well, however, for some reason I can't get it to show the form errors. There should be form errors based on the ValidationErrors I have put in the model form. I suspect my views.py to be the cause of the form not displaying the errors. Here's my view: class ProfileSettings(UpdateView): model = Profile template_name = 'profile/settings.html' form_class = ProfileForm success_url

问题 So I've spent the day trying to chase down a custom thing that I wanted to achieve using FormView. When I use FormView with HTML form method="POST", I am able to get the desired result, mostly. If a user clicks to submit a form and an empty field exists, they get an error message telling them the form is required. I'm aware that I can make the ModelChoiceField required on the form, but was trying to implement my own logic for this. I found through my searching that if I'm not updating

问题 I have a contactform in the footer of a website. So it is on every page. It works, with one problem: as soon as it is sent, it doesn't show anymore.

问题 I am currently struggling with Django forms. Based on the tickets model I generate this formset where users can choose the qty of tickets they want. After they will be redirected to the checkout page. My problem is, when I use {{ form.ticket }} I get a select field but that's not what I'm looking for.

问题 I feel like I'm really close, but not quite there yet. Please bear with me as I am very much so in the beginner stages of learning django. I have a feature where users can comment on each blog post. I want to display the total number of comments each user has next to his name. If that user has left 4 comments on 4 different posts, I want it to show "4 total comments" next to his name on each one of his individual comments throughout my website. I have made a model method that I put in my view
