A quick tip for generating HTML ID attributes from Rails: there is a helper
method named #dom_id. You use it like this: dom_id(designation_dict), and by
default, you get [object classname]_[numerical id] as a string. It takes an
optional prefix as the second argument, which gets prepended, so if you did
dom_id(designation_dict, :edit), you would get edit_designation_dict_42 out of
it. This comes in really handy when you are setting up an ID in a view, and
then again in a UJS file or similar. You don't have to fiddle around with a lot
string concatenation in two places that way.
