I'm rather new to Django but am getting pretty competent doing most of
the basic things. This is not so much a problem, more so trying to
find the best way to do something.
We are creating a website for searching our resources here in the
office. We have an advanced search that allows us to search
information that is related to the "Resource" being searched. The
advanced search allows for a keyword and then 3 select fields that are
information from other tables. A simple version of my model is below.
class Resource(models.Model):
first = models.ManyToManyField(First)
second = models.ManyToManyField(Second)
third = models.ManyToManyField(Third)
So now when I search from our advanced form, the URL looks something
like:
http://site/search/?keyword=stuff&first_id=1&second_id=2
What is the best way to create a queryset for this without doing tons
of if statements, like:
if request.GET['first_id']
if request.GET['second_id']
if request.GET['third_id']
queryset =
Resource.objects.filter(first__id__exact=request.GET['first_id'],
second__id__exact=request.GET['second_id'],
third__id__exact=request.GET['third_id'])
else
queryset =
Resource.objects.filter(first__id__exact=request.GET['first_id'],
second__id__exact=request.GET['second_id'])
else
queryset =
Resource.objects.filter(first__id__exact=request.GET['first_id'])
elseif
#... so on
That just seems like the worst way to do it. Can I pass a dictionary
to it somehow? What's the best way to do something like this?
Hope this wasn't extremely confusing. Let me know if you need any
other information from me.
Thanks a lot,
Stephen Mizell
