I have submitted this PR <https://github.com/rails/rails/pull/9622> without
any discussion, but maybe i should have asked here first: what do you think
about adding new Action View helpers to generate hidden input fields from a
nested hash?
This can be used to store data in HTML form instead of cookies. I would
work like this:
hidden_field_tags_from_nested_hash({ :a => { :b => ['c', 'd']}, 'e' => 5 }, :id
=> nil)
Output:
<input name="a[b][]" type="hidden" value="c" /><input name="a[b][]"
type="hidden" value="d" /><input name="e" type="hidden" value="5" />
