Hi.

We differentiate transactions by using methods with different names depending on the target DB.
So I would like to be able to leave the transaction on_lock as the default and add another method name to use it.

like..

Rails/TransactionExitStatement:
  TransactionMethods:
    - transaction
    - on_lock
    - some_custom

Before submitting the PR make sure the following are checked:

  • The PR relates to only one subject with a clear title and description in grammatically correct, complete sentences.
  • Wrote good commit messages.
  • [ ] Commit message starts with [Fix #issue-number] (if the related issue exists).
  • Feature branch is up-to-date with master (if not - rebase it).
  • Squashed related commits together.
  • Added tests.
  • Ran bundle exec rake default. It executes all tests and runs RuboCop on its own code.
  • Added an entry (file) to the changelog folder named {change_type}_{change_description}.md if the new code introduces user-observable changes. See changelog entry format for details.
  • [ ] If this is a new cop, consider making a corresponding update to the Rails Style Guide.

I understand the use case. However built-in transaction methods and custom methods should not be treated the same I think. So, can you update this PR to mixin the AllowedMethods and AllowedPatterns modules in Rails/TransactionExitStatement to specify allowable custom methods.
e.g. rubocop/rubocop#11019

Thanks for review.
As requested, I rewrote it using the AllowedMethods, AllowedPatterns modules.
Did you mean treating built-in transaction methods as separated constants not default of AllowedMethods?
If there is something different from your intention, please let me know.

That's just my two cents. Can you rename this file to changelog/new_add_allow_methods_and_allow_patterns_to_transaction_exit_statement.md?

It should be CustomModel instead of extending ApplicationRecord, right?

…nExitStatement`

Follow up rubocop#1072.

This PR renames `AllowedMethods` to `TransactionMethods` for `Rails/TransactionExitStatement`
because it's a configuration for detecting, not for allowing custom transaction methods.

@marocchino I made a mistake and merged this. This is a configuration to detect, not to allow custom transaction methods. So I've opened #1088.
