It is the URL of the script that you write to be the Ajax backend: you can call it what you like, and put it where you like (though it introduces many problems if it isn't on the same domain as the script it's being called from). > Since my app is a Rails one I tried to create a partial (list_item) > with the list item and I passed it as a url but I get "Couldn't find > Person with ID=list_item > If I remove the url parameter I get " > ActionController::MethodNotAllowed Only get, put e delete requests > are allowed." even if I specify get as a method. I don't know Rails, but if it's anything like symfony, a partial isn't enough: it needs to be its own page, which will parse the arguments from the query string, generate the output, and send it with the proper headers. It could be bare text, XML, HTML or it could be empty and return the data in an X-JSON heaader. But if you're going to use Ajax.Updater, you need to return an HTML fragment (not a whole HTML page). In any case, though, it needs to have suitable HTTP headers. I'm guessing that Rails has a way of creating a page which only returns the headers and text you want.

[Proto-Scripty] Re: autocomplete variant
Hello,
I have an issue with Ajax.updater.
Since I'm a prototype newbie I guess it is something easily solvable.
Basically I don't understand what I have to put as url.
In any example I can find on prototype website they show '/some_url'
without specifying its meaning.
Since my app is a Rails one I tried to create a partial (list_item)
with the list item and I passed it as a url but I get "Couldn't find
Person with ID=list_item
If I remove the url parameter I get "
ActionController::MethodNotAllowed Only get, put e delete requests
are allowed." even if I specify get as a method.
How can I fix it?
Any help is greatly appreciated.
Sig

Thanks Colin for your reply.
Your second option sounds exactly what I need.
I try to make it works.
Have a nice day.

There are several separate parts of this:
- generating the entries to include the checkboxes
- acting on the result.
The Ajax.Autocompleter in scriptaculous requires you to return an
unordered list for the 'drop-down', and there's nothing to stop you
putting elements inside the 's. If you still want to use
the "pick an entry from the list and it will be as if that had been
typed in the text input box", you can do that - make sure the
elements are inside , and the Autocompleter
code will ignore them in generating the value to return.
However, I'm guessing that that is not what you want, but rather for
the user to proceed by ticking some of the boxes. In that case, I
don't think Ajax.Autocompleter is going to be much use to you, and you
might just as well use Ajax.Updater and do the rest yourself. You can
possibly copy some code from Ajax.Autocompleter.
The code you want (in very sketchy form) is something like
observe($('textbox'), 'keypress', function() {
Ajax.Updater('listdiv', ...
{parameters: { partname: $F('textbox'), ...
});
And then your Ajax backend would match the 'partname', and deliver a
list of
Tom
or maybe just lines with between
You'll need more than this - probably want to put a delay on before
sending, so as not to send until the user has stopped typing for a
bit, and to handle ESC and things. You can copy some of these out of
Ajax.Autocomplete.
