dependent => :delete_all
Reported by Sergei | August 17th, 2008 @ 06:39 PM | in 2.x
By mistake, when describing a model I said "dependent => delete_all" without the leading colon before "delete_all". Rails complained and I put the colon in. The surprise came when I saw that all development data from the table that the model described were gone.
Now, I understand that delete_all in the context of a rails class describing a model will indeed delete everything but somehow I didn't expect that side effect while describing a "has_many" association :)
Maybe this report could be useful.
Thanks, Sergei

In Ruby, a method called at the class level is called directly on the class.
Item.delete_all # is the same as class Item delete_all endI do see how it's an easy mistake to make, but I don't think there's an easy solution to this since it's how Ruby behaves.

Creating a feature request
Please don't. If you want a new feature in Rails, you'll have to pull up your sleeves and get busy yourself. Or convince someone else to do it. See the contributor guide on how to get going. But posting them here is just going to lead to ticket root.
Creating a bug report
When creating a bug report, be sure to include as much relevant information as possible. Post the code sample that causes the problem. Preferably, alter the unit tests and show through either changed or added tests how the expected behavior is not occuring.
Security vulnerabilities should be reported via an email to security@rubyonrails.org, do not use trac for reporting security vulnerabilities. All content in trac is publicly available as soon as it is posted.
Then don't get your hopes up. Unless you have a "Code Red, Mission Critical, The World is Coming to an End" kinda bug, you're creating this ticket in the hope that others with the same problem will be able to collaborate with you on solving it. Do not expect that the ticket automatically will see any activity or that others will jump to fix it. Creating a ticket like this is mostly to help yourself start on the path of fixing the problem and for others to sign on to with a "I'm having this problem too".
