问题 I am very new to Django and at the end of my rope and really need some help. I do not know how to use a "class based view" and change the incoming datetimefield from my MySQL database into a Time Zone Supported entry that it seems to need. The database stores it in UTC and my system is on PST. I am getting this error: DateTimeField received a naive datetime (2012-09-01 00:00:00) while time zone support is active On my MonthArchiveView, DayArchiveView, DateDetailView 's only.

问题 I am looking to add a a variable into the file name section of my below python code so that the downloaded file's name will change based on a user's input upon download.

I saw a similar question but based in PHP and couldn't figure out how to adapt it to python. response = HttpResponse(content_type='application/vnd.ms-excel') response['Content-Disposition'] = 'attachment; filename= "Data.xlsx"' Thanks

问题 I'm uploading an image file in a basic Django web app. There's an upload button in the html template wrapped around by a form tag. Once the upload button is pressed, the underlying view takes over and processes image upload. In the Chrome browser of my colleague's Macbook, pressing upload multiple times really quickly manages to call the underlying function multiples times too. I end up getting a plethora of copies of the image being uploaded. However, this isn't replicatable in my own

问题 I am getting a 405 METHOD NOT ALLOWED response when I am trying to submit a POST request through an AJAX call: "POST /events/profile_update/ HTTP/1.1" 405 0 I'm trying to set this up with the most basic view: def profile_update(request): if request.method == "POST": name_form =forms.EventName(request.POST) if name_form.is_valid(): name = name_form.cleaned_data['name'] else: name_form = forms.EventName() return render(request, 'event_edit_profile.html', {"name": name}) my urls.py: urlpatterns

问题 I'm surprised to find that an ORDER BY DESC query on a FloatField in Django returns null fields higher than fields with positive values. # In models.py class City(models.Model): name = models.CharField(max_length=30) country = models.ForeignKey(Country) value = models.FloatField(null=True, blank=True) # In views.py cities = City.objects.filter(country__id=country.id).order_by('-value') # In template.html {% for city in cities %}{{ city.name }}: {{ city.value }} --{% endfor %} I get back the
