* Added that form helpers now take an index option #448 [Tim Bates]
|
||||
|
||||
Example:
|
||||
text_field "person", "name", "index" => 3
|
||||
|
||||
Becomes:
|
||||
<input type="text" name="person[3][name]" id="person_3_name" value="<%= @person.name %>" />
|
||||
|
||||
* Fixed three issues with retrying breakpoints #417 [Florian Gross]
|
||||
|
||||
1. Don't screw up pages that use multiple values for the same parameter (?foo=bar&foo=qux was converted to ?foo=barqux)

# used by render_collection_of_partials, the "index" option may come in handy. Example:
