Dom manipulation and Rails

Ruby on Rails Intermediate Rails Tutorial

Let’s say I have a list of items in the dom that can be reordered with javascript. How do I allow the user to make another request without affecting their reordering?

You’d probably need to persist their ordering somehow. Depending on what it is you’re doing, you would might be able to do this with the users’ cookies, and reorder them using Javascript when the page loads, or implement a table to order things server side with something like this:

create_table :orderings do |t|
  t.integer :sort
  t.belongs_to :orderable, polymorphic: true
  t.belongs_to :user
end

Thanks I’ll try that.
