Hehe not a silly question, yes, I have, I also got a recommendation to
try using the :inverse_of argument on the relationships too. Which
didn't haven any effect on the problem.
I've come to the conclusion that accepts_nested_attributes_for works
kinda like url_for... Where the presence of ID makes it assume the
relationship exists. Rendering accepts_nested_attributes_for not
suitable for what I want to do.
I've worked around this with a before filter:
def find_line_item_types
params[:category][:line_item_types] =
LineItemType.find(params[:category][:line_item_types].collect { |a|
a[0].to_i }) if params[:category] and
params[:category][:line_item_types]
end
Thanks for replying! :)
