Lighthouse has a new layout.
Prefer the old one? Return to the old layout,
and switch back any time from the link at the top of each page.
This project is archived and is in readonly mode.
ActionView::Helpers::FormHelper#fields_for API changed in master
#6727
ActionView::Helpers::FormHelper#fields_for now has four params
(record, record_object, options, block) in master instead of three
(record_or_name_or_array, args, &block) in Rails 3.0.6.
I'm mostly surprised that a public method has changed between
releases without deprecation warnings, documentation, etc. It also
bugs me that the params are different to
ActionView::Helpers::FormBuilder#fields_for. The change seems to
have been introduced in 58d3b9042302d41f90fc129f12787d83f7bdade9
("Speed up form_for by specializing extract_options!") by Yehuda in
August (can be found in the diff between v3.0.6 and master).
Ideally this change would be reverted, or perhaps a backwards
compatible way to keep the optimisation can be found.
