I need help setting up my existing project on another computer
I’ve got a Rails application with PostgreSQL that lives on GitHub. Right now I only work on it from my laptop and commit changes there.
I want to get this same codebase running on my desktop computer so I can switch between machines when coding. The app is currently deployed on Heroku too, so I’ll need to sync the database changes and other stuff.
Git is already installed on my desktop machine. What’s the best way to clone this repository and get everything working locally? Are there specific git commands I should use to download the source code to my desktop?
hey! to get your code, just use git clone https://github.com/yourusername/yourrepo.git. then go into the folder and run bundle install. remember to also adjust your database.yml for postgres and run rails db:create db:migrate. u’ll be all set!
Git clone grabs your source code, but here’s what people miss - you only get the main branch locally. Push any unpushed feature branches from your laptop first. On your desktop, run git branch -a to see remote branches, then git checkout -b feature-name origin/feature-name for the ones you need. Set up git config with the same username and email so your commits stay consistent. Database setup’s easy with migrations, but make sure Gemfile.lock gets committed - it keeps both machines on identical gem versions and kills those “works on my machine” headaches.
Since you’ve got Git already, it’s pretty straightforward but Rails apps have some gotchas. After you clone it, copy over your environment variables file or make a new one - Rails needs database credentials and other secrets that don’t get committed. Check your Ruby version matches the project, then run bundle install for the gems. For the database, if you need actual data from your laptop’s dev database, dump it with pg_dump and restore on your desktop. Otherwise just run migrations on a fresh database. The trickiest part’s usually getting the environment config right.
