I''m developing an application using RoR that will generate enough email notifications that I don''t want them in the actual web application. So, I''m thinking about having an outgoing queue that a cron job would pick up and deliver. My question is if this is possible with a ruby script that uses ActiveRecord and ActiveMailer?

Hi Railers, A long, long, time ago, i made a Framework/CMS in php. There were two core models: Content and Content_type. Content_type was only a list of content types (as expected): new, article, etc. Content_type was not mandatory, but it allowed later to "deactivate" types of contents, for example. So then Content stored the common attributes/properties between the different content

I''m using ActionWebService to allow users to upload files to my rails app. I do this by encoding to Base64. The problem with this is that rails logs the file data so my log file size spirals out of control. Is there any way to selectively disable logging when the web api is invoked? ActiveRecord::Base.silence doesn''t seem too useful here as it''s only called AFTER

I have two tables ("products" and "categories") that have a has_and_belongs_to_many relationship, and I need to be able to arbitrarily sort products in the scope of a category using something like acts_as_list. Problem is, since each product can belong to multiple categories, it doesn''t work to use acts_as_list and have the "position" field be in the

Hi guys, After a few days of webrick seeming to use up a ton of ram (the longer it was running, the more ram); izayoi on #rubyonrails kindly suggested changing Dependencies.mechanism in development.rb to :require which appears to have fixed the prob - at the expense of having to restart webrick after making changes to .rb files. Is this a known issue, or is there an alternative solution?

Hello happy Railers, I used to develop with a local out-of-the-box Apache and load times were pretty slow (like a few seconds each page). "Well, it''s the price to pay for no compile / cache / etc..." I thought. Nonsense. Yesterday I installed SCGI, and now I''ve got the best of both worlds: rails development env uses my very latest modifications, while SCGI ensures I

So each sale has_many :products through => pops And each product has_many :sales

On my website people will be able to upload images of themselves. I was wondering how people are presently handling uploading, resizing and optimizing images in Rails?
