问题 I am trying to find the most injured player from my query but I am having trouble getting the proper results. I was thinking of putting the player ID's in a list but how do you go about counting duplicate entries and then producing a "top 5" most injured list? Here is my models.py class PlayerInjury(models.Model): player = models.ForeignKey(Player) injury_type = models.ForeignKey(Injury) injury_date = models.DateField(verbose_name='Injured On', null=True, blank=True) description = models

问题 I'm trying to create a marketplace website similar to craigslist. I created a form according to the Django tutorial "Working with forms", but I don't know how to render information I got from the POST forms. I want to make information(subject,price...etc) that I got from POST show up on another page like this. http://bakersfield.craigslist.org/atq/3375938126.html and, I want the "Subject"(please look at form.py) of this product(eg.1960 French Chair) to show up on another page like this. http:

问题 I am making a django application where it will have 2 apps. When you open www.webName.co.id it will use urls.py from app A, but when you open webName.co.uk it will use urls.py from app B This is the urls.py from the main project: urlpatterns = [ url(r'^tinymce/', include('tinymce.urls')), url(r'^filer/', include('filer.urls')), url(r'^ckeditor/', include('ckeditor_uploader.urls')), url(r'^admin/', admin.site.urls), ] I was planning to add something like this to that file: if settings.CURRENT

Do I do it in the template level or in the view level (I don't even know how to do it in the template level)? Or maybe I need to pass the actual object to the form and initiate in the form level? What is the best practice? EDIT: For @Bento: In my original Form , I'm doing something like this class

问题 My current setup in views.py looks like this def order_detail(request, pk): order = Order.objects.get(pk=pk) # Define the can_something variables here. include_fields = [] if can_edit_work_type: include_fields.append('work_type') if can_edit_vendor: include_fields.append('vendor') if can_edit_note: include_fields.append('note') class OrderDetailForm(forms.ModelForm): class Meta: model = Order fields = tuple(include_fields) form = OrderDetailForm(instance=order, data=request.POST) return

问题 Edit: I'm using Django dev version so I do have access to JsonResponse (as seen below). I'm messing around with Django and trying to make it work with AngularJS. Currently I'm attempting to query 4 rows from a database at a time and send the results as a JSON object to an Angular script. I just keep running into issues though - it won't work.

问题 In Rails, I used the application_controller to control things like user sessions, and create objects to populate parts of the site like the menu. How should this be done in Django, since there is no kind of "application view"? Do you have to use custom filters and partial templates to be included, for instance in the base template to do this? I have also been looking at class-based views, but am unsure if that is it. 回答1: There are several ways to accomplish this: Template Tags Context

问题 I am working on an application where a user can upload an image. I want to reduce the size of the image in 200-500kb.
