I've just upgrade my rails application from the 3.0.7 version to the release candidate 3.1.0 and I got a strange error located in my atom feed builder:
ActionView::Template::Error (wrong number of arguments (1 for 0)):1: atom_feed do |feed|2: feed.title("site name")3: 4: for post in @postsapp/views/posts/index.atom.builder:1:in `_app_views_posts_index_atom_builder___1517323884_2197638100'It seems to need an argument in the atom_feed method, but I tried to put something in it and it hasn't fixed the problem. It worked before the upgrade.
