collection_select doesn't populate the drop down list

I'm having an issue using collection_select to create a drop down menu. All the guides say that this

<%= collection_select(:page, :user_id, @users, :id, :full_name, :include_blank => false) %>

should work but when I run the server, instead of a list of users appearing it's just a blank list. The associations are that page belongs a user and a user has many pages, and there are users in the database that should be obtained in the controller when I call @users = User.all

Any idea on how to get the drop down list to populate?

This is the html code that is generated so something is missing/wrong but I'm not sure what it is.

<select id="page_user_id" name="page[user_id]"> <option value="1"> </option> <option value="2"> </option> <option value="3"> </option> <option value="4" selected="selected"> </option> <option value="5"> </option> <option value="6"> </option> <option value="7"> </option> </select>

Do those numbers look like valid user_id values? If so, are you sure your User model has a full_name method?
