I am trying to do the same thing. I followed the same tutorial, added the
@user_session = UserSession.new
(tried both the home controller and application controller)
but I am still getting
ActionView::Template::Error (undefined method `model_name' for NilClass:Class):
1: = form_for @user_session do |f|
2: -if @user_session.errors.any?
3: #error_explanation
4: %h2= "#{pluralize(@user_session.errors.count, "error")} prohibited
this user_session from being saved:"
app/views/user_sessions/_form.html.haml:1:in
`_app_views_user_sessions__form_html_haml__892280163_96031200'
app/views/home/index.html.haml:6:in
`_app_views_home_index_html_haml__1051594895_96219820'
Any idea how to solve this? Everything else works fine, as described in the
tutorial. I am just unable to render the partial user_sessions/form from
anywhere else, i.e. it's only working from user_sessions/new.
I'd appreciate any help, I've been struggling with this for a while and cannot
figure it out.
