Undefined method error

class Task < ActiveRecord::Base
  belongs_to  :court
  has_many    :workflow_tasks
  has_many    :task_users, :dependent => :destroy
  has_many    :court_users, :through => :task_users
end

class TaskUser < ActiveRecord::Base
  belongs_to  :task
  belongs_to  :court_user
end

I accessed the court_user as follows:

task.task_users.collect{|task_user|task_user.court_user.user.name}

Error:

undefined method `court_user'' for #<TaskUser:0x60f4320>

Anyone knows the solution. It only happens in the development mode. It
seams the autoloading not working properly.

If I find the TaskUser directly like following it will work, but this is
not the right solution.

task_users = TaskUser.find(:all,
:conditions=>[''task_id=?'',task.id])
task_users.collect{|task_user|task_user.court_user.user.name}

do you ever require a class that could be autoloaded? that can fox
autoloading. There was a thread about this recently here.

Re: Undefined method error

Ahh yes, but is it defined the other way around? Does a CourtUser have any
relationship defined to task_user inside court_user.rb?

Re: Undefined method error

I''m telling you that you haven''t defined it inside the file
app/models/court_user.rb! Please listen carefully, it stops me repeating
myself.

You need to either have a belongs_to :task_user or a has_one :task_user or..
a task_user method defined on CourtUser.

Your table structure has nothing to do with this.

Yeah, we have defined
has_many :task_users  in the court_user.rb.

Re: Undefined method error

The solution is simple: You have defined a has_many :task_users on
court_user meaning that there is no task_user (note the lack of an S) method
on court_user.

Either you define it as has_one :task_user or reference it as task_users.

Re: Undefined method error

The required classes were not included in the task_user.rb.

require ''court_user.rb''.

I missed this somehow.

Thanks all for your support.

Re: Undefined method error

This is a shot in the dark since I''m really struggling in
understanding how your tables work together, but instead of,
    "task.task_users.collect{|task_user|
task_user.court_user.user.name}"
how about,
    "task.task_users.collect{|task_user|
task_user.court_users.user.name}"
or this,
    "task.task_users.collect{|task_user|task_user.users.name}"
