The purpose of this method

Ajedi32 ยท Feb 8, 2013

This method keeps track of whether a hidden id field needs to be created when the form builder is generating fields for a nested model. It gets set to true by #hidden_field when that method is used to create a field named 'id'.

Here's an example of what this can be useful for: http://railsforum.com/viewtopic.php?id=39640
