I have tried updating the urls and the views to this but i keep getting error responses
path("add_page/<str:title>", views.add_page, name="addpage"),
def add_page(request, title):
Please advise where this error response could be coming from as the above edits is what i saw in some other stackoverflow responses to clear the error but this didn't work for me.
Thank you
When you make a redirect to entrypage, you need to specify the title, so:
from django.shortcuts import redirect
def add_page(request):
if request.method == "POST":
form = AddPageForm(request.POST)
entries = util.list_entries()
if form.is_valid():
title = form.cleaned_data['title']
content = form.cleaned_data['content']
util.save_entry(title, content)
for entry in entries:
if title.upper() == entry.upper():
return render(request, "encyclopedia/errorpage.html")
# specify title ↓
return redirect('encyclopedia:entrypage', title=title)
# …I would also strongly advise to make use of a database, and not fetch all entries from the utility: a database is optimized to search effective, whereas accessing the list of files takes linear time to search. If you define a database model, you can add db_index=True [Django-doc] to build an index which can boost searching enormously.
