Hi! I know that the web is essentially stateless, so I was wondering about how lost connections can be managed. I have an application that posts data to a web form. This form has a large number of items (about 38) and I''m a bit concerned about the connection being lost while posting the data. Is it safe to assume that the web application will reject the transmission if the right

Hi, I''m trying to follow the "AWDR" example of storing certain types of numbers (in my case, percentages not money) as integers in the database.

I tried using render_action to specify the template explicitly, and it "works". But I

There are areas of my application that "want" to use a url structure like domain/<human_readable_param>/<Module>/<Controller>/<Action>/<Id> Please note that the human readable parameter I need to inject is NOT related to the <id> being used by the action/controller pair.

I have two problems. I have a comment that has_many uploads. Before saving the comment, I want to be sure that the upload(s) has passed validation, but I also need to validate in other ways. For example, I do not want to save the comment if there is no comment or upload. Or, I do not want to save the comment if the image has been uploaded previously (comparing md5s with past upload md5s

I''m trying to re-flow email messages, removing the line breaks that get added by mail programs so that the lines don''t exceed 72 characters. Mail.app and Thunderbird seem to insert a space character before each added line break.

Hello all. Am relatively new to RoR and I am pondering how to do something without using components since they appear to be "coda non grata". I have a standard layout that is used by all controllers. In this layout I want to list the next 5 events that are upcoming based on todays date. These events are currently stored in the Event model (created using scaffolding). Currently only

What I want: I get a normal http request containing a URL from a remote server. Instead of redirecting to that URL, I want to load it into an iframe on an existing page. I''ve tried a number of approaches with no success. Can anybody suggest a good way to do this? Alternatively, if you can say "this is bloody impossible, because....", that would be helpful, too. --Al Evans

"Beast" is more appropriate than you know. It''s definately Frankenstein code. (read: it ain''t pretty, but it works - some of the time). Anyway, it entertains my wife; not sure if hardcore programmers will get anything out of it or not.
