i know not worth serious time answer, haven't been able figure out. please help, , let me know if need more info. again in advance!

change

<%= form_for(:user, :url => {:action => 'edit'}) |f| %>

to

<%= form_for(@user) |f| %>

in instance, don't need specify action use. default conventions in rails take care of you.
