I have the requirement to empty the association records and add the
association records as new (as below).
@task = Task.find(params[:task_id])
@task.task_users = []
params[:ids].split(", ").each do |court_user_id|
task_user = TaskUser.new(:court_user_id => court_user_id)
@task.task_users << task_user
end
@task.save
This is not working. Following error is thrown.
ActiveRecord::AssociationTypeMismatch (TaskUser expected, got TaskUser):
C:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.15.6/lib/active_record/associations/association_proxy.rb:148:in

`<<''
C:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.15.6/lib/active_record/connection_adapters/abstract/database_statements.rb:59:in
`transaction''
Any body know why this error has thrown for the above logic.
Task.rb has the following code.
belongs_to :court
has_many :workflow_tasks
has_many :task_users, :dependent => :destroy
has_many :court_users, :through => :task_users
I would appreciate if anyone can address this issue.
Thanks,
Ayyanar. A

At present, iam using the below logic to make the application work, but
i don''t like this logic since you know the loopholes in the logic. No
transaction.
I want the above logic to work.
@task = Task.find(params[:task_id])
TaskUser.delete_all("task_id=#{params[:task_id]}")
params[:ids].split(", ").each do |court_user_id|
task_user = TaskUser.new(:court_user_id => court_user_id, :task_id =>
params[:task_id])
task_user.save
end

This is the same problem as your undefined method: the autoloading is getting screwed, probably because of you requiring a class by hand that you didn''t need to. This results in there being more than one instance of the TaskUser class hanging around: the one from before rails reset your application following the previous request and the one from the new request.

Inspect your params data, and see if what is being passed to update_attributes (I assume that''s what''s at line 45 of the clistings_controller) is what you expect. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
