I have created a calendar that is embedded in my website. There is an option for admins to create events and when I try to create an event, I get faced with a 405 Error. Could someone please point me in the right direction into why this isn't working, when in previous versions of Python Django, it was working?
My code is below for convenience:
urls.py
from django.urls import path
from main_website import views
from main_website.views import (AboutView, ArticleCreateView,
ArticleDeleteView, ArticleUpdateView,
CalendarView, ContactUsView, DonateView,
EditEventView, EventView, HelpUsView,
ImageAddView, ImageCategoryAddView,
ImageDetailView, ImageGalleryView, IndexView,
SearchView, TaggedView)
urlpatterns = [

Your calendar/event/new/ route points to EventView, which only has a get method defined. Posting to a view without a post method will produce a 405 error.
Also, your EditEventView doesn't edit an event, but instead always creates a new event.
To fix this, you need to do this:
- Copy the post method in
EditEventViewtoEventView. - Change the original post method in
EditEventViewto only edit existing events:
EventEditView post method:
def post(self, request, event_id):
instance = get_object_or_404(Event, pk=event_id)
form = EventForm(request.POST or None, instance=instance)
if form.is_valid():
form.save()
return redirect('main_website_calendar')
You should also implement some error handling in these post requests, but I'll leave that to you.
EDIT:
EventView post method:
def post(self, request):
instance = Event()
form = EventForm(request.POST or None, instance=instance)
if form.is_valid():
form.save()
return redirect('main_website_calendar')
