#583 √ resolved
Szymon Nowak

SQL queries with WHERE IN are incorrectly generated for named scopes

Reported by Szymon Nowak | July 9th, 2008 @ 11:17 AM | in 2.x 

class Post < ActiveRecord::Base
  named_scope :recent, :conditions => [...]
end

class Author < ActiveRecord::Base
  belongs_to :post
end

posts = Post.recent
Author.find_all_by_post_id(posts)

This generates the following query:

SELECT * FROM `authors` WHERE (`authors`.`post_id` = 107,108,109)

instead of using WHERE IN clause.

Casting ActiveRecord::NamedScope::Scope object into Array object using posts.to_a fixes the problem, but it should be done automatically by dynamic finder method.

Creating or reviewing a patch

See the contributor guide.

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"..
