I have a date select:

\<%= form\_fields.date\_select :birthday\_on, :order =\> [:month, :day,  
:year], :start\_year =\> 1900 %\>

In my controller I want to set the individual attribute. How do I do  
this?

user.birthday\_on = params[:user][:birthday\_on]

How do I convert this to a date so it set properly?

Thanks for your time!
