I'm trying to figure out the best way to create basic search forms in
Django. Currently I'm using newforms and have a simple view that takes
the parameters, calls the appropriate filters and returns the results.
--------------------------------------------------------------------------------
# newform
class ProjectSearchForm(forms.Form):
p_type = forms.ModelChoiceField(queryset =
ProjectType.objects.all(), required=False)
p_stage = forms.ModelChoiceField(queryset =
ProjectStage.objects.all(), required=False)
p_status = forms.ModelChoiceField(queryset =
ProjectStatus.objects.all(), required=False)
# view
def project_search(request):
p_type = request.GET.get('p_type', None)
p_stage = request.GET.get('p_stage', None)
p_status = request.GET.get('p_status', None)
data = {'p_type':p_type,
'p_stage':p_stage,
'p_status':p_status,
}
search_form = ProjectSearchForm(data)
if search_form.is_valid():
results = Project.objects.all.(),order('name')
if search_form.data['p_type']:
results =
results.filter(p_type=search_form.data['p_type'])
if search_form.data['p_stage']:
results =
results.filter(p_type=search_form.data['p_stage'])
if search_form.data['p_status']:
results =
results.filter(p_type=search_form.data['p_status'])
else
results = []
context = Context()
context.update({'search_form': search_form})
context.update({'results': results})
return render_to_response('projects/projects_list.html',
RequestContext(request, context))
--------------------------------------------------------------------------------
However, it seems like I should be able to abstract things so that I
the actual field only show up in the form declaration.
- I don't have to set each field to send into the form
- I don't have to set a filter for each field
Something more like this:
--------------------------------------------------------------------------------
#view
def project_search(request):
#create search form with current request variables or using intial
values for form?
search_form = ProjectSearch(request.GET)
if search_form.is_valid():
#QuerySet filter created by search form?
results = Project.objects.filter(search_form.filter)
else:
results = []
context = Context()
context.update({'search_form': search_form})
context.update({'results': results})
return render_to_response('projects/projects_list.html',
RequestContext(request, context))
--------------------------------------------------------------------------------
I've been looking around a bit at generic views, but it didn't seem to
be quite what I am looking for. Is this type of generic search form
currently possible?
Any help would be appreciated. Thanks!
