In my application.html.erb, I have a navigation bar that stores the user avatar. He or she should be able to return to the main index or traverse through the different controllers without issue. I seem to be getting a "Cannot find avatar for type ActiveRecord::Relation"
undefined method `avatar' for nil:NilClass Application.html.erb <%= if user_signed_in? %> <li class="round-image-50"><%= image_tag(@user.avatar.url(:thumb), unless: avatar.nil?) %></li> User.rb has_attached_file :avatar, :styles => { :medium => "200x200>", :thumb => "100x100>" }, :unless => "avatar.blank?", :url => "/assets/users/:id/:style/:basename.:extension", :path => ":rails_root/public/assets/users/:id/:style/:basename.:extension" validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/ The avatar uploads successfully when the user registers, and the file itself is attached to the user object. Do you have a solution for this problem? And how would you enable the app to show all user avatars globally? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
