I have a sortable list that I serialize and pass to ruby to parse the
results and update my array of hashes.
eg.
$tasks = [
{ :id => 1, :name => ''Do the dishes'', :position =>
3 },
{ :id => 2, :name => ''Take out the trash'', :position
=> 2 },
{ :id => 3, :name => ''Shovel the driveway'', :position
=> 1 }
]
My hurdles:
(1) serializing and passing with Ajax
var list = Sortable.options(''tasks'').element;
new Ajax.Request(''/tasks'', { parameters:
Sortable.serialize(list)});
I get this:
tasks%5B%5D=2&tasks%5B%5D=1&tasks%5B%5D=3
would it be more useful if It was formating it as such?
task{id}={position}&
Where are the %5B%5D coming from?
(2) parsing it in ruby
I grab the request with web brick and I pass the query to params
params = request.query
How do I go about parsing it and updating my array of hashes?

Even though JSON is really cool I''m not sure if thats what I need. I have the Pragmatic Prototype and Scriptaculous book and in there AJAX samples they didn''t need toJSON. check out my pastie. I just not sure how to work with serialized info once its passed to webrick.

Prototype is certainly well equipped for it.

That would be the simpler solution but it may not be practical for my me. I''ll moving this code over to an asp classic system. I was just using it in ruby for simple testing and showing purposes. When should I use JSON over send requests with Ajax?

I try to help people if they''re using the built-in Rails helpers to generate their JavaScript for them, but generally server-side talk is best taken to other lists that specialize in the technology you are using. Especially if we''re talking about old school ASP ;)> When should I use JSON over send requests with Ajax?I''m not sure I understand your question. Are you asking when is it appropriate to use JSON to send data over Ajax? If so, the answer is really up to you. Some people use JSON exclusively for Ajax communication, and other people may use it rarely, if ever. It''s up to what works best for your environment/style. Since you mentioned switching to ASP, then maybe most of the questions you have in this thread are irrelevant since ASP will unescape parameters for you *and* have the methods in place to extract the values you are looking for in the Request object, like: Request("tasks[0]"). -justin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

Im not the one implementing it in asp, or yet that I know of. I''d be railing if it were up to me. But for my testing purposes I''d like to know how its possible just passing a request similar to what Pragmatic did in there book.
