I have an existing Django app on Bitbucket and I'm able to deploy to Heroku whith hg-git. Whenever i want to run some heroku command inside my app folder i get the following errors:
$ heroku ps
! No app specified.
! Run this command from an app folder or specify which app to use with --app <app name>
$ heroku logs
! No app specified.
! Run this command from an app folder or specify which app to use with --app <app name>
etc.
Current workaround is to specify the app name: heroku ps --app <app name> but i'm looking for a way to link my repository name to the remote Heroku app name like how it's done using git.
I'm not in a position to move my app to github for now.
I'd suggest trying Hg-Git's "intree" configuration option. Set that by adding the following to your hgrc:
[git]
intree = True
With that set, the Git repository used internally by Hg-Git will be stored as a ".git" directory within the working copy, rather than nested within the ".hg" directory.
Heroku will then see this repository's config. Add a remote as suggested in the other answer (quoted below), and you should be all set.
git remote add heroku git@heroku.com:<app-name>.git
For now, the best documentation of Hg-Git configuration options that I've found is the README displayed on the project's Bitbucket page: https://bitbucket.org/durin42/hg-git
Considering heroku is looking at the .git/config file to get the app name, just do the following inside your local repository:
git init
git remote add heroku git@heroku.com:<app-name>.git
In order not to mess your repository, you'll also add the following lines to .hgignore:
#Git setup
.git/**
Now, usual heroku commands no more ask for the default app name.
