I've an existing project that works fine on another machine, but I've just upgraded and from within the project development directory, everytime I run a heroku command I have to post-fix it with --app
I feel like I've missed an application setup stage, but I can't figure out what, as everytime it states: Run this command from an app folder or specify which app to use with --app APP.
Help appreciated.
You can solve this by adding the Heroku app to your .git/config folder.
If you are in the root of your project, run the following command:
git remote add heroku git@heroku.com:appname.git
This will set a line in your .git/config file which the heroku command line tool uses to figure out what app you're using :)
In other words, your local repo doesn't have Heroku app URL configured against an app name
Similarly what we do with git remote add ( we pass git URL as a destination for push/pulling of code ) that how our git know which repo/URL to hit (push/pull from )
Heroku also follows the same method/process. All you have to do is add Heroku app URL (so that ur Heroku command have a reference for app URL )
it will know against which URL you are running your command against
To confirm if remote named Heroku has been set for your app:
git remote -v
if not configured or if you want it for an existing app
heroku git:remote -a app_name
it's a way to link your folder to the Heroku app
The Heroku recommended way:
heroku git:remote -a my-heroku-app-id -r what-i-want-to-call-it
Run this command from an app folder or specify which app to use with --app APP
The other answers address the first part of that statement, it is perfectly acceptable to run heroku commands in any directory. For example I have a customer facing front end project /front-end and a rails based /back-end project. I often work in the /front-end directory and if I have to connect to the production database I'll run heroku run rails c -a back-end. After I exit irb then I'm back in my desired directory.
