The form field won't show up in the browser. There is only the submit button showing up.
views.py code:
def vote(request, pk):
# check if request is post
if request.method == 'POST':
# create a form and populate it with data from request
form = forms.Vote(request.POST)
if form.is_valid():
fact = Fact.objects.get(pk=pk)
fact.votes += int(form.cleaned_data['vote'])
fact.save()
return HttpResponseRedirect(reverse(
'facts:detail',
args=(pk,)
))
else:
form = forms.Vote()
return render(request, 'facts/fact_detail.html', {'form': form})
template(fact_detail.html) code:
<form method='POST'>
{% csrf_token %}
{{ form }}
<input type="submit" value="vote" />
</form>
Form class(forms.py) code:
VOTE_CHOICES = [
(1, 'upvote'),
(0, 'downvote')
]
class Vote(forms.Form):
vote = forms.ChoiceField(choices=VOTE_CHOICES, widget=forms.RadioSelect())
In views.py for the vote method initialize the form variable locally, before passing it as a parameter.
def vote(request, pk):
form=""
//rest of the code//
return render(request, 'facts/fact_detail.html', {'form': form})
我建议从Django文档中检查通用编辑视图,我认为它具有解决方案[ https://docs.djangoproject.com/en/1.11/ref/class-based-views/generic-editing/#createview][1]
