Couldn't find Class with ID=#num
Reported by Ryan Bigg | August 18th, 2008 @ 01:53 AM | in 2.x
In Rails 2.1, in my controller I have:
Client.find(params[:id], :joins => [:address, :mailing_address])
where the mailing_address association is possibly nil. Doing a find on a client with this code where the client's mailing address is nil, it says:
Couldn't find Client with ID=1
This is misleading, since the Client with the id of 1 DOES exist.

The :joins parameter adds an INNER JOIN clause to the query, which causes the database to filter out clients without a mailing_address.
Replacing :joins with :include gives the desired behaviour (by using a LEFT JOIN clause).
The error might seem misleading, but there's no way rails could tell the difference between a missing mailing_address and a missing client when :joins is used.
This ticket should probably be closed.

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"..
