Question

All,
I’m trying to basically do keyword notifications, so whenever an object with a name is created, anyone who wants to be notified of any of the words in this name will be.
e.g.

Records:
   keyword: Hello
   keyword: World

New Name: "Hello World"

Returns both records

I’ve created a query that correctly works for this in sqlite, and I know how to translate it across databases.

SELECT * FROM table t
WHERE "a constant string" LIKE "%" || t.field || "%";

I’ve determined that within django, one can use F() objects to compare one field to another field, like so:

Entry.objects.filter(n_comments__gt=F('n_pingbacks'))

Now anyone know how to replace the first field with a constant string? Like so:

Entry.objects.filter("constant string"__icontains=F('n_pingbacks'))

Or am I going about this backwards?

You should not try to fight with django ORM. It covers the most often things but your case is not the one. Just use extra to get what you need (or even raw).
