Hi,
Just a guess…

<% for email in @contact.emails %> <% fields_for "contact[email_attributes][]", email do |e| %>

So this will generate
params[:contact][:email_attributes][<email_id>][<email_field>] =>

Each element in this params is a hash.
Check your server logs to verify that that is what you’re getting.

def email_attributes=(email_attributes)
email_attributes.each do |attributes|

email_attributes is a hash with keys being email id’s pointing to
email attributes.
See previous note above.
When you do email_attributes.each |attributes| , ‘attributes’ will be
an array with the first
value being the key and the 2nd element being the value.

emails.build(attributes) unless attributes["email"].empty?

Calling attributes[“email”] would trigger the above conversion error
because arrays expect numeric indexes.

end
end

Also, I noticed you’re saying “:id => @contact” . I would have though
@contact.id but might be missing something.
