Yep, that's true. I based my code on the canonical blog posts / comments example, so in views/premises/edit.html.erb, I wrote: <%= form_for([@premise, @premise.metered_services.build(:account_identifier => "gas")]) do |f| %> <%= f.submit "add gas account" %> <% end %> ... and it clearly calls build() whenever it renders the page. But this leads to two questions: * (Curiosity:) How did render(... :collection) know about the newly created metered_service without an ID? I know that premise.metered_services.build will create a new record, but it appears that the new record doesn't appear on the premises.metered_services list until it's saved. * (Necessity:) Assume the user is looking at views/premises/edit.html.erb. I want a button that says "add metered_service to the current premise". What's the right way to do that? (Clearly, I haven't made friends with form_for() just yet.)
