Can't perform Querying using Q objects

[Ajay M]

Hi I'm a newbie to Django. I'm trying to implement a search feature like this.

query_results = Shops.objects.filter\
                            (Q(shop_name__icontains=search_text)\
                            |Q(state__state_name__icontains=search_text)\
                            |Q(city__city_name__icontains=search_text)).distinct()

I would like to search Shops based on the shop_name, state_name and city_name. State and city fields are foreign keys. For some 'Shops' stateandcity are null. However, shop_name contains the search_text. So I'm not getting those 'Shops' by running this query. Any help on this is appreciated.

At least when using Postgres that query makes a LEFT OUTER JOIN so it shouldn't discard Shops just because they don't have a state or city.

So your query seems to be OK

are you sure your search text is fine? the orm will not automatically strip the search_text into a list of keywords or things like that. For example, searching for "ski shop" will not match a Shop with name "ski super shop".

Hi Vijay,
The search text is okay.. I think when  using the state__state_name and city__city_name relations Django INNER JOIN removes the shop without existing relation from the result.

At least when I tested a similar query it makes an OUTER JOIN, not an INNER JOIN

What's the actual SQL command being executed?

print Shops.objects.filter(...).query
