How to search one model only in Haystack

How to search one model only in Haystack

I've got an app with two models, Restaurant and Dish. Dish has a foreign
key to Restaurant. I'm trying to build separate search forms using
Haystack, one for people to search by Restaurant.name and another to
search by Dish.name.
I'm having trouble separating this out and understanding how Haystack does
this. Since I created both of the indexes below, when I have a SearchForm,
if I type in "shrimp" in the search box it will return "grilled shrimp",
and if I enter in "ShakeShack" the results will return "ShakeShack". My
goal is to have a restaurant search form where if you type in "shrimp" you
shouldn't be getting anything back any results because there are no
restaurants with "shrimp" in the name. but right now my form seems to be
allowing searching both models.
My Indices:
class RestaurantIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
def get_model(self):
return Restaurant
class DishIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
def get_model(self):
return Dish
My search form:
class MySearchForm(SearchForm):
sqs = super(MySearchForm, self).search()
if not self.is_valid():
return self.no_query_found()
return sqs
I've tried inserting sqs.models(Restaurant) to limit to only search/return
results from the Restaurant model but it's not working. I've also tried
putting this in the url conf:
SearchView(searchqueryset=SearchQuerySet().models(Restaurant)
any help would be appreciated!
thanks! yin
