I have been following the DAL tutorial and can access a json object at
http://127.0.0.1:8000/entry/river-autocomplete/?q=S
So i know my view is working. Beyond that I cannot seem to get anything but the standard widget for ForignKey. From looking at the following posts in stackoverflow I feel that some static files or javascript libraries are not loading properly but for the life of me I cannot figure out how to fix this.
django-autocomplete-light template not rendering autocomplete widget
django-autocomplete-light displays empty dropdown in the form
Below are all of the files that I think pertain to this issue. If I can clarify things any further please let me know.
views.py (edit added full views.py)
class CreateEntry(LoginRequiredMixin, generic.CreateView):
fields = ('date', 'river', 'flow', 'description', 'public')
model = JournalEntry
def form_valid(self, form):
self.object = form.save(commit=False)
self.object.user = self.request.user
self.object.save()
return super().form_valid(form)
def get_success_url(self):
return reverse_lazy('home')
#autocomplete view
class RiverAutocomplete(autocomplete.Select2QuerySetView):
def get_queryset(self):
#User filtering code goes here
if not self.request.user.is_authenticated:
return River.objects.none()
qs = River.objects.all()
if self.q:
qs = qs.filter(river_name__istartswith=self.q)
return qs

I have tried to use the exact {% block content %} that is in the tutorial without a differing result. Any help would be much appreciated.
Second question: I am pretty new to posting on stackoverflow and wonder if anybody has a good rule of thumb about how many hours one should spend researching and trying on your own before you post a question?
CodePudding user response：
You are not passing your form class to the view, just passing fields means that the form you are using is just an auto-generated ModelForm without your custom widget
class CreateEntry(LoginRequiredMixin, generic.CreateView):
model = JournalEntry
form_class = JournalForm
