you got that error because @user was nil
if you're using devise, you can try this instead "current_user.avatar.url(:thumb)"
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>
