GeoIP.country_code_by_name(query)

select_related(*fields) Returns a QuerySet that will “follow” foreign-key relationships, selecting additional related-object data when it executes its query. This is a performance booster which results in a single more complex query but means later use of foreign-key relationships won’t require database queries. The following examples illustrate the difference between plain lookups and select_related() lookups. Here’s standard lookup: # Hits the database. e = Entry.objects.get(id=5) # Hits

fields Returns a list of the names of the fields of data associated with the feature. This will be the same for all features in a given layer and is equivalent to the Layer.fields property of the Layer object the feature came from.
