The site uses the delayed_jobs plugin to handle some background tasks and I'd like to be able to run rake jobs:work on the development server to periodically process all jobs in the queu...

I then have a bunch of events which occupy some of these intervals, for example event = { start_at: somedatetime, end_at: somedatetime } Iterating over events from a certain date to a certain date, I create another ar...
I'm using the delayed_job plugin in Rails to do background processing, and I'm experiencing a hiccup in the 'agile development' I've been experiencing so far in Rails... Usually in rails if I hit an error / want to add some new functionality - I just add some code and refresh the page and the new code runs. With delayed_job, it seems l...

I don't know if this is bad form or not, but I needed to set a file path that's accessible to all objects within actions in my controller. One action in the controller creates a file and stores it in a path. Another action serves the file using send_file.

Unless specified, ActiveRecord fires up 4 default connections. I've noticed if I reload a simple page, which makes at least one ActiveRecord call, 4 times every thing functions normal. However, on the fifth time, it hangs for almost 5 seconds. So, every 5th page load it hangs for 5 seconds. I upped the default connection pool in my ada...

Hi There, I've been working with a rails form all day and I was just randomly testing it and tried the date 25/12/2009 and it came up with a huge error. It was at this point I realised that rails is set to american date mode (mm/dd/yyyy) instead of the UK style: dd/mm/yyyy. How can I set rails to automatically deal with all dates in d...

I have a Ruby on Rails app with Livepipe widgets - http://livepipe.net/ - and everything has been going great, until the client asked for a modal ontop of another modal. Swapping between modals isn't a problem, but they'd like to see one modal behind the other. I can tell that the tag with the id="control_overlay" is the issue - both ...
Hi, I have a page where a user can import data to the site. either in the form of copy and pasting into a text area from excel, or by uploading a .csv file. The controller checks if a csv has been uploaded - if so it processes this, else it will process the pasted content. (working on the assumption the user will only choose one option...

I get the following error: No route matches {:controller=>"application", :action=>"index"} I had many tests fail in the same way, but was able to fix them by including the correct parameters in the get call. So for insta...
