If you've found a bug in Ruby on Rails, this is the place to start. You'll need to create a (free) GitHub account in order to either submit an issue, comment on them or create pull requests.

|
||||
|
||||
NOTE: Bugs in the most recent released version of Ruby on Rails are likely to get the most attention. Also, the Rails core team is always interested in feedback from those who can take the time to test _edge Rails_ (the code for the version of Rails that is currently under development). Later in this guide you'll find out how to get edge Rails for testing.

||||
h4. Creating a Bug Report
|
||||
|
||||
If you've found a problem in Ruby on Rails which is not a security risk do a search in GitHub Issues in case it was already reported. If you find no issue addressing it you can "add a new one":https://github.com/rails/rails/issues/new. (See the next section for reporting security issues.)

If you've found a problem in Ruby on Rails which is not a security risk, do a search in GitHub under "Issues":https://github.com/rails/rails/issues in case it was already reported. If you find no issue addressing it you can "add a new one":https://github.com/rails/rails/issues/new. (See the next section for reporting security issues.)
|
||||
|
||||
At the minimum, your issue report needs a title and descriptive text. But that's only a minimum. You should include as much relevant information as possible. You need to at least post the code sample that has the issue. Even better is to include a unit test that shows how the expected behavior is not occurring. Your goal should be to make it easy for yourself - and others - to replicate the bug and figure out a fix.

|
||||
|
||||
Then don't get your hopes up. Unless you have a "Code Red, Mission Critical, The World is Coming to an End" kind of bug, you're creating this issue report in the hope that others with the same problem will be able to collaborate with you on solving it. Do not expect that the issue report will automatically see any activity or that others will jump to fix it. Creating an issue like this is mostly to help yourself start on the path of fixing the problem and for others to confirm it with a "I'm having this problem too" comment.

Please don't put "feature request" items into GitHub Issues.

Later in this guide you'll find detailed instructions for proposing a patch to Ruby on Rails. If you enter a wishlist item in GitHub Issues with no code, you can expect it to be marked "invalid" as soon as it's reviewed.

After applying their branch, test it out! Here are some things to think about:

You should not be the only person who looks at the code before you submit it. You know at least one other Rails developer, right? Show them what you’re doing and ask for feedback.
