12: <% each_page do |page| -%>
13: <% if page.current? -%>
Thanks.
I found this question : Rails heroku help kaminari view error. So i'd delete (and backup if necessary) your current views and regenerate them again

I checked everything and i didnt found an error, i had just created the project and installed the plugin.
I was using a old version of the devise plugin in the new version of the ror. =x
I'm experiencing a really weird issue. When I fork the active_admin gem and use the forked, unchanged version it gives me the following error:
Sprockets::CircularDependencyError in Active_admin/devise/sessions#new
/Users/Victor/.rvm/gems/ruby-1.9.2-p180/bundler/gems/active_admin-916ecdd04e3c/app/assets/javascripts/active_admin/base.js has already been required
Extracted source (around line #12):
9: <%= stylesheet_link_tag style.path, style.options %>
10: <% end %>
11: <% ActiveAdmin.application.javascripts.each do |path| %>
12: <%= javascript_include_tag path %>
13: <% end %>
14:
15: <%= csrf_meta_tag %>
When I use the original version there are no errors. How is this possible if the two versions are identical?
Yes.you can remove the line
//= require_directory ./
in
/.rvm/gems/ruby-1.9.2-p180/bundler/gems/active_admin-916ecdd04e3c/app/assets/javascripts/active_admin/application.js
Remove active_admin.js from your app/assets/javascripts folder - it looks like it is no longer needed.
I am running a pretty straight forward Rails 3.2 app on Dreamhost (I know its lame).
The error is:
NoMethodError in Products#edit

It sounds like #product is returning nil, but if you look at line 44, it didn't error when requesting #product in that case?
any ideas?
EDIT

I had the same problem and I made two changes, unfortunately not separately, and one or both solved the problem.
First, in your controller do you build a photo in your edit method?
#product.photos.build if #product.photos.empty?
I found that in the comments on this blog post.
Second, I added a symbol for the nested class to the 'link_to_add' line, which you already have.
I was switching from a has_many to has_one and was getting this same error. Azolo's response fixed my issue.
Removed the <%= f.link_to_add......%> tag and all is working nicely!
I really can't figure out why I can't access the user_id field for the class Post. I have it as a field in my database (I can see it, and it isn't blank. Yet for some reason, I'm getting this error:
undefined method `user_id' for #<Class:0x103497448>
Extracted source (around line #10):
7: <h2>Topics</h2>
8: <% #board.topics.each do |topic| %>
9: <% #post = topic.posts(1) %>
10: <b><%= User.find(#post.user_id).username %> says <%= link_to topic.subject, [#board, topic] %></b><br />
11: <% end %>
12: <% end %>
13:
topic.posts(1) will return an array. Hence #<Class:0x103497448>
The right way to get the first post for a topic would be
9: <% #post = topic.posts.first %>
10: <b><%= User.find(#post.user_id).username %> says <%= link_to topic.subject, [#board, topic] %></b><br />
Try <% #post = topic.posts.limit(1) %>
