问题 I want to create records on two different tables (venue and parking) via one form using accepts_nested_attributes_for. I want a user to be able to create a new venue, and also specify the parking options available to that venue via checkboxes.

It's a pretty basic setup, with a minor complication in that my LineItem model is a two-word relationship (:line_items). However, I've followed Rails guidelines and it seems to be working OK. My fixtures are creating the proper relationships between line_items and invoices, and everything is showing up properly in my views, but I can't get any line_item records to save
