If both forms are used in the same view, I see little reason to make them
separate and ModelForms, the form class I put above should be a better
choice.
In order to do the actual filtering, you can do something like this
class ScreeningForm(forms.Form):
haircolor = forms.ChoiceField(choices=CandidateLook.HAIRCOLOR_CHOICES,
required=False)
status = forms.ChoiceField(choices=CandidateToJob.STATUS_CHOICES,
required=False)
def filter_job_candidates(job):
assert self.is_valid()
job_candidates = job.applied_to.all().order_by('candidate')
if self.cleaned_data['haircolor']:
# You need to change the "user" field in CandidateLook to a
OneToOneField for this to work, which doesn't change anything since the
field is already a primary key that can't be repeated either way
job_candidates = job_candidates
.filter(candidate__candidatelook__haircolor=self.cleaned_data['haircolor']
if self.cleaned_data['status']:
job_candidates = job_candidates
.filter(status=self.cleaned_data['status']
return job_candidates
And in your view...
class Screening(generic.DetailView):
model = Job
template_name = 'dashboard/screening.html'
def get_context_data(self, **kwargs):
context = super(Screening, self).get_context_data(**kwargs)
# Fetch the sender_id for each unread message.
# Count the number of times that the sender_id was included.
# Then convert the list of tuples into a dictionary for quick
lookup.
sent_messages = dict(
self.request.user.received_messages.filter(
read_at__isnull=True
).values('sender_id').annotate(
messages_sent=Count('sender_id')
).values_list('sender_id', 'messages_sent')
)
form = ScreeningForm(self.request.GET)
if form.is_valid():
job_candidates = form.filter_job_candidates(self.object)
else:
# Fallback, since the form will always be valid unless someone
tampered with the form parameters manually
job_candidates =
self.object.applied_to.all().order_by('candidate')
candidates = []
for candidate in job_candidates:
candidate.messages_sent = sent_messages.get(
candidate.candidate.user.id)
candidates.append(candidate)
context['candidate_list'] = candidates
context['form'] = form
return context
