</div>

\<%= task.task\_users.collect{|task\_user| task\_user.court\_user.user.name}

The above code throwing the following error.

undefined local variable or method `task\_users’ for  
#\<#Class:0x5e8899c:0x5e88974\>

Task.rb has the following code:

has\_many :task\_users, :dependent =\> :destroy

This happens only in the development server.

in the forums.
