Add multiple database support for write operations during GET requests - #1791

@copilot rename active_record_options config option to enable_multiple_databases - let's avoid coupling to ActiveRecord so any Doorkeeper extension (like for Sequel or any other ORM) can use it's own implementation to support primary-replica. |

All was good @copilot before you changed 3000+ files. Why did you touch vendor/ folder? Remove these changes |
I apologize for the issue. The vendor/bundle files were accidentally committed in afc4fca when running tests locally. The files are now properly excluded via .gitignore (commit 0e013e7), but they remain in the commit history. To completely remove them from the repository history, the branch needs to be force-pushed after rewriting history with Would you like me to:
The actual code changes in afc4fca (guard clause and condition swap in write_to_primary.rb) are correct and working. |

@copilot rebase the branch |
I'm unable to rebase the branch because:
To rebase this branch, you'll need to run these commands locally: git fetch origin main
git rebase origin/main
# Or for interactive rebase to squash/reorganize commits:
git rebase -i origin/main
git push --force-with-leaseAlternatively, if you want me to make any specific changes to the code itself, I can do that and create new commits. |
