One field form - do i need Form class
I want to have search form with just one field. Should I use Form class or is it overkill? -- You received this message because you are subscribed to the Google Groups "Django users" group.

Django +Ajax + jQuery problem
My problem is that site registers only the first click on .upvote or
.downvote element and ignores next ones.

DJango upvoting, downvoting - functions in templates
I'm using this package https://pypi.org/project/django-vote/ and i want to
do something smilar to this guy
https://github.com/shellfly/django-vote/issues/51 - I need function
callable in template, which will tell me if user has downvoted or upvoted,
but exactly downvoted or exactly upvoted. I don't know where should I put
it's code to make it work. It should take two arguments: user_id and answer.
My view:
def question(request, question_id):
question = get_object_or_404(Question, pk=question_id)
form = AnswerForm()
return render(request, 'questions/question.html', {'question': question,
'form' : form},)
I'd like to use this function here with upvote, downvote elements.:
{% for answer in question.answers.all %}
{{answer.author}}
{{answer.content}}
↑
{{answer.votes.count}}
↓
{% endfor %}
Also I'm not sure which functions can be called in Django templates. Only
those having no arguments?

Ajax and Django and jQuery - .attr()
I have a problem with Ajax and Django templates. I'm new to Ajax and jquery.
Console log at the end of the script prints undefined. I don't know why let
answerid = $(this).attr("answer-id"); doesn't extract attribute from this
line: ↑
I also want to know if using template tags in javascript scripts like here $
.post("{% url 'upvote' %}", {answer_id:answerid}) is a good idea.

{% for answer in question.answers.all %}

Re: Redirect to login page without losing content of form
Ok. Now I've dealt with this returned None problem, but I still have no
idea what to do to keep my form content after clicking submit button. Does
next parmeter generated by login_required contain only link or also form
content?

Redirect to login page without losing content of form
*I* have problem similar to this one:

I want answer to be added if user is logged in otherwise redirect user to
login page, let him login and then add his answer. My problem is that I
lose content of the form.
At the moment I'm getting this errror:

returned None instead.

def answer(request, question_id):
question = get_object_or_404(Question, pk=question_id)
form = AnswerForm(request.POST) if request.method == 'POST' else
AnswerForm()
if form.is_valid():
answer = form.save(commit=False)
answer.author = request.user
answer.question = question
answer.save()
return HttpResponseRedirect(reverse('question', args=(question.id,)))
{% csrf_token %}
{{form.as_p}}
