Get a value of object field inside fields_for loop

Question

In the following scenario, I need to check the value of the object property in the fields_for loop.

<%= f.semantic_fields_for :review_details do          


        

Answer 1

I got it, I can use

rd.object.review_criteria_id

object is the default wrapper object for the fields_for loop.

Answer 2

Formtastic adds additional features to the Rails code, but doesn't take away existing functionality so the following should work for you:

rd.object.review_criteria_id

'object' can be used in plain Rails form helpers to access the underlying bound object, and Formtastic honours this convention.
