Hi, i''m having trouble implementing a sortable drag and drop list. in
my controller i have the following code:
def sort
@test_case = TestCase.find(params[:id])
@test_case.tasks.each do |task|
task.position =
params[''task-list''].index(task.id.to_s) + 1
task.save
end
render :layout => false
end
the drag and drop operations work but the database does not get
updated. The list to be updated is in another controller though. I
have tried several ways but still haven''t got the DB to update. The
code where i call the function:
<%= sortable_element ''task_list'', :url => { :action
=> "sort", :id =>
test_case.id, :controller => ''test_case'' },
:complete => visual_effect(:highlight, ''task_list'')%>
Any help is greatly appreciated, thanks!

Thanks for the reply. It actually works now but using bugzilla I see that internally theres the error You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating nil.index I just don''t understand why. It does now update the pos in the database, and the list is correct... I guess I shouldn''t complain anymore, but I would still like to understand this behavior.
