I've got a table that includes a column named "valid". This has caused a problem after updating to Rails 2. ActiveRecord is expecting "def valid?" to do validation, not return a boolean value from the database. How do I work around this problem? Is renaming the column my only option? ...
Hello, I am writing a document for a Rails application that I wrote. Apart from a word document, I need it to be a web document as well. And since I do not have a lot of time, I was wondering if there is a CSS framework that will help me facilitating the process. So is there a CSS framework that is specifically designed for documentat...

I'm using the task gettext:find getttext_18n_rails. I tried before with the classic updatepo task but was the same. Perhaps am I missing any gem? ...
What's the best way to keep users from sharing session cookies in Rails? I think I have a good way to do it, but I'd like to run it by the stack overflow crowd to see if there's a simpler way first. Basically I'd like to detect if someone tries to share a paid membership with others. Users are already screened at the point of login fo...

Hi, This is a pretty basic question but I can't find a good answer for it. I have a page in my Rails app where there are many objects that can be 'flagged'. Clicking the flag button should display a little box with a confirmation, little form, etc. The trouble is I can't figure out how to do this using RJS templates. I've been usin...
Sorry for such a trivial question, but I'd feel silly building this if it already existed. I have a vague memory of there being a Rails helper that could turn ['one', 'two', 'three'] into "one, two, and three", but I could be totally making things up. And I can't quite figure out where in the API to look since it's not in the TextHelper...

Is it possible to create a .zip/.tar file on S3 without first copying them back to the server? Our app runs on a large dedicated box and I'd love to save...

I've come across a weird bug for ie7 where the css styles get applied differently when I access "/400.html" and "/500.html" directly as opposed to being redirected to it by a controller. The controller code for redirection is: respond_to do |format| format.html { render :file => "#{RAILS_ROOT}/public/404.html", :status => "404 Not ...

Still new to Rails. I'm certain there's a naming convention for what I'm trying to do here. You've got posts, and then you've got tags (I'm not actually making a blog but this a scenario we're all familiar with). I'd set up my tags like this: ruby script/generate scaffold tag name:string Then I'd create a linking table like this: ...
