[Answer]-Django generic CBVs passing variables from templates to views

Ignore my comment regarding keyword arguments – that shouldn’t make a difference.

You have a mistake in your url. The regex group board_id has it’s parenthesis in the wrong place. It should be:

url(r'^view_board/(?P<board_id>\d+)/$', ViewBoardDetails.as_view(), name='view_board'),

Hard to spot, but ?P(<board_id>\d+) should be (?P<board_id>\d+)
