First off, thank you for considering contributing to Active Admin. It's people like you that make Active Admin such a great tool.
If you've noticed a bug or have a question that doesn't belong on the mailing list or Stack Overflow, search the issue tracker to see if someone else in the community has already created a ticket. If not, go ahead and make one!
If this is something you think you can fix, then fork Active Admin and create a branch with a descriptive name.
A good branch name would be (where issue #325 is the ticket you're working on):
git checkout -b 325-add-japanese-translations
Make sure you're using a recent ruby and have the bundler
gem installed, at
least version 1.14.3
. The most reliable bundler
version to use is the same
Travis is using.
Install the development dependencies:
bundle install
Now you should be able to run the entire suite using:
bundle exec rake test
This will automatically run the tests against Rails 5.0. But you can easily run
tests against older versions of Rails too by changing the Gemfile
bundler
uses.
Run, for example,
export BUNDLE_GEMFILE=gemfiles/rails_42.gemfile
And then everything will be run against Rails 4.2.
The test run will generate a sample Rails application in spec/rails
to run the
tests against.
If your tests are passing locally but they're failing on Travis, reset your test environment:
rm -rf spec/rails && bundle update
-
Ensure the bug was not already reported by searching on GitHub under Issues.
-
If you're unable to find an open issue addressing the problem, open a new one. Be sure to include a title and clear description, as much relevant information as possible, and a code sample or an executable test case demonstrating the expected behavior that is not occurring.
-
If possible, use the relevant bug report templates to create the issue. Simply copy the content of the appropriate template into a .rb file, make the necessary changes to demonstrate the issue, and paste the content into the issue description:
At this point, you're ready to make your changes! Feel free to ask for help; everyone is a beginner at first 😸
Active Admin is meant to be used by humans, not cucumbers. So make sure to take a look at your changes in a browser.
To boot up a test Rails app:
bundle exec rake local server
This will automatically create a Rails app if none already exists, and store it
in the .test-rails-apps
folder.
You should now be able to open http://localhost:3000/admin in your browser. You can log in using:
User: admin@example.com
Password: password
If you need to perform any other commands on the test application, just pass
them to the local
rake task. For example, to boot the rails console:
bundle exec rake local console
Or to migrate the database:
bundle exec rake local db:migrate
Once you've implemented your code, got the tests passing, previewed it in a browser, you're ready to test it against multiple versions of Rails.
bundle exec rake test_all
This runs our test suite against a couple of major versions of Rails. Travis does essentially the same thing when you open a Pull Request. We care about quality, so your PR won't be merged until all tests pass.
At this point, you should switch back to your master branch and make sure it's up to date with Active Admin's master branch:
git remote add upstream git@github.com:activeadmin/activeadmin.git
git checkout master
git pull upstream master
Then update your feature branch from your local copy of master, and push it!
git checkout 325-add-japanese-translations
git rebase master
git push --set-upstream origin 325-add-japanese-translations
Finally, go to GitHub and make a Pull Request :D
If a maintainer asks you to "rebase" your PR, they're saying that a lot of code has changed, and that you need to update your branch so it's easier to merge.
To learn more about rebasing in Git, there are a lot of good resources, but here's the suggested workflow:
git checkout 325-add-japanese-translations
git pull --rebase upstream master
git push --force-with-lease 325-add-japanese-translations
A PR can only be merged into master by a maintainer if:
- It is passing CI.
- It has been approved by at least two maintainers. If it was a maintainer who opened the PR, only one extra approval is needed.
- It has no requested changes.
- It is up to date with current master.
Any maintainer is allowed to merge a PR if all of these conditions are met.
