I run into problems now because they are executed parallel of course :) How can I garuantee that the Calls are executed when the page has loaded completely ? And, more interesing, how can I make one AJAX-Call start when the previous has completely finished ? I''ve read about Effect.Queues - is

I was recently having problems accessing attributes in an object. Can somebody explain to me why this is, and if it is a bug?

Hi All Not specifically a scriptaculous question, but I was wondering how people were going about maintaining access to their applications via standard urls.

Here''s the scenario. I have a main tree-like table (actually it''s more of a hierarchy), where the entries (or at least some of them) can be categorised as one or more of a fixed number of types (prob about 6 poss types). So an entry could be a Type A and a Type D; a Type C, D, E; just a Type F; etc. Having a join table would seem like it might get rather expensive since

Hello, Is it possible to trigger an action in a controller when a table from database changes? I thought about using an utility like cron (railscron) to check every, e.g. 2 s, if the table changed, but I am wondering if there is a solution a bit more ''elegant'': to trigger an action exactly when the change is made.

Somebody suggested SmallCap and that sounds great. This is by no stretch of the imagination Capistrano, so it might better be named MicroCap but it may be useful to some who have (as I do) modest needs in this regard, especially for on-server versioning.

Instead of using sequential integers for IDs for my objects I was wondering if I could easily make it so that my IDs where longer auto- generated random strings/integers. So instead of: http://www.mydomain.com/user/view/1 Would be: http://www.mydomain.com/user/view/d81096b87a7c5565f On top of that... is there big benefits for security reasons to use non-sequential numbers? Is it worth

Firstly, I''m still learning Ruby and rails, so there could be a very simple solution to this. I want to search across multiple tables with a "like" query eg: (SQL is probably the easiest way to describe it): select products.* from products inner join brands on products.brand_id = brands.id where products.name like ''%canon%'' or brands.name like

Greetings! Is there a way to get RoR to redirect_to another action after doing a sendfile? My little app lets the user enter a bunch of data and then creates an XML file from it. I''m using sendfile to let the user download the XML file. Once they download the file I want to take them to a new view that presents a logout button that will trigger a cleanup.

OK, general question for the community -- what''s the coolest startup using Rails? I don''t think "37 Signals" is a fair answer. I''m curious as to what kind of other developments are happening.
