问题 I'm trying to display a form (ModelForm) with a select field filtered by currently logged in user. The select field in this case contains a list of categories. I want to display only the categories which "belong" to the currently logged in user. The category field is a foreign key to the IngredienceCategory model. Here is what I've come up with so far but it's giving me an error (unexpected keyword queryset). Any ideas what I'm doing wrong? # models.py class IngredienceCategory(models.Model):

问题 I like to raise 404 with some error message at different places in the script eg: Http404("some error msg: %s" %msg) So, in my urls.py I included: handler404 = Custom404.as_view() Can anyone please tell me how should I be handling the error in my views. I'm fairly new to Django, so an example would help a lot. Many thanks in advance. 回答1: In general, 404 error is "page not found" error - it should not have customizable messages, simply because it should be raised only when a page is not found

问题 I'm new to Django (and Python), and am trying to figure out how to conditionalize certain aspects of form validation. In this case, there's a HTML interface to the application where the user can choose a date and a time from widgets. The clean method on the form object takes the values of the time and date fields and turns them back into a datetime . In addition to the HTML interface, there's also an iPhone client making calls into the application, and I'd like to pass a UNIX timestamp-style

问题 I have to insert 2 forms in the same page: 1) Registration form 2) Login form . So if I use this in the views.py: if request.method == 'POST': form = registrationForm(request.POST) if form.is_valid(): form.save() return render_to_response('template.html', { 'form': form, }) I will get error by submitting one of two forms. How can I distinguish the 2 forms submitting in the views ? 回答1: You can also do like this, <form method='POST'> {{form1.as_p}} <button type="submit" name="btnform1">Save
