Hello experts, I have a very weird problem, when storing my session in Memcached. From time to time some users takes the session of others. E.g.

In the home page I want to show only quizzes that are ready for consumption: they must have a number of questions and a number of possible answers. Of course I could query with SQL, or create a class method retrying all objects whe...

I'm wondering if it's possible to configure a Rails email derived from ActionMailer to send to a different recipient based on the environment. For example, for development I'd like it to send mail to my personal email so I don't clog up our company email account with "Testing" emails; for production however I want it to use the real add...
Hi there, We're running 3 Apache Passenger servers sharing the same file system, each running 11 Rails applications. We've set PassengerPoolIdleTime = 0 to ensure none of the applications ever die out completely, and PassengerMaxPoolSize = 20 to ensure we have enough processes to run all the applications. The problem is that whe...
Hello, I'm wondering why this is not working for me: Recipe.find_or_create_by_user_id(current_user.id, :name => "My first recipe") That creates the recipe fine if one does not exist by the user's id, but the name ("My first recipe") isn't included into the newly created entry. Is there something I'm doing wrong? I can't quite figure ...

I have a Rails app that's getting hit by ScanAlert calling /login.php, but the app is throwing a 500. I'd like to filter any format that's not supported by my site, and 404 instead. My original inclination was to create a before_filter in application_controller.rb that removes any :format that's not :html, :xml, or :js, then render 404....

I run a Rails app, and we're in the process of splitting out our signup process to a separate app. The signup app has its own separate database (for CMS and collecting prospects), but it also needs to have access to the main database. This works really well using ActiveRecord::Base.establish_connection. However, I'd like to be able to ...
I am using Lightbox Gone Wild to display a modal dialog with a form inside. I am using a vanilla New view. This works like a champ up until a user doesn't input valid form data. Invalid data causes the controller to direct the user to the New view directly with the error message. Obviously, I would prefer the error be returned to the mod...
I'm using a javascript call to dynamically remove a field from a form. My problem is that the action happens very quickly, and it's not reversible. So I'd like to add the standard Rails delete confirmation, but I can't figure out how to make it work. Basically, I want to add this ... :confirm => ‘Are you sure?’ Here's the line of j...

That is, Every such entity had a title, descriptions, tags, a user_id etc and some other attributes....
I'm using s3-swf-upload-plugin in a Rails project to upload directly to S3. Pretty nifty, but can't seem to figure out how to make the uploaded files public. S3 doesn't seem to have the concept of public "buckets". Any ideas? ...
So for an ERB file, what's the difference between <%- ... -%> vs. <% ... %>? As far as I can tell, they serve the same purpose but one requires more typing than the other. ...
I notice it's used primarily for sending emails. Let's say I want to send an email after every comment is created. Is using Observers really necessary when you could just place the Mailer.deliver_email(user) in your comments_controller.rb's create action instead? ...
