double underscore are used for field lookup. It is similar to SQL WHERE clause.

Im Getting this error. Tried a lot but couldnt get through:

NoReverseMatch at /boards/1/topics/1/
Reverse for 'boards_topics' with arguments '('',)' not found. 1 pattern(s) tried: ['boards/(?P\d+)/$']

Did you later figure this out?

The numbering of topics does not start newly for every board, but is global for all topics, regardless of the board, they are created in. Therefore topics/1/ refers to the first topic you created on the whole forum. If this was in a different board, then boards/1/topics/1/ does not exist. There might exist boards/2/topics/1/ or boards/3/topics/1/ or ... depending on the board, where you created the very first topic. Also you might find boards/1/topics/2/ or boards/1/topics/3/ or ... depending on the order in which you created topics.
