I have the following setup

class Education \< ActiveRecord::Base  
has\_and\_belongs\_to\_many :users  
end

class User \< ActiveRecord::Base  
has\_and\_belongs\_to\_many :educations  
end

In my user-view-rhtml i have:

```
  <% @user.educations do |education| %>
    <li><%= education.name%></li>

```

This generates empty data…

Question…is my .rhtml wrong or my models??

guess…

I think the problems is in the iteration in your view, it should be:  
\<% @user.educations.each do |education| %\>

- \<%= education.name%\>
