I have two emails for a contact. The first email is primary.While saving  
a new contact I can only set one radio button for primary, but in edit  
page the primary radio button can be set for both emails(not mutually  
exclusive)

View

 \<% for email in @contact.emails %\> \<% fields\_for "contact[email\_attributes][]", email do |e| %\> Email \<%= e.select ('email\_type',%w{Business Personal}, :include\_blank =\> false) %\> \<%= e.text\_field :email,:size=\>"35",:maxlength=\>"80" %\> \<%= e.radio\_button ('isprimary', 'true') %\>Primary \<% end %\> \<% end %\>
