Question

I logged in to my app’s directory in Heroku’s server:

Heroku run bash -app appname

Then I deleted my database:

Rm -r dev.db

However when I try to sync my database it doesn’t create new tables. And when I go to the production site, it still has all database contents and lets me log in, etc.

Any insight into what I’m doing wrong? I want to completely recreate the database.

Note: I have a Django app

Update: Here are my database settings

DATABASES = {
    "default": {
        "ENGINE": "django.db.backends.sqlite3", # Add "postgresql_psycopg2", "postgresql", "mysql", "sqlite3" or "oracle".
        "NAME": PROJECT_ROOT + os.sep + "dev.db",                       # Or path to database file if using sqlite3.
        "USER": "",                             # Not used with sqlite3.
        "PASSWORD": "",                         # Not used with sqlite3.
        "HOST": "",                             # Set to empty string for localhost. Not used with sqlite3.
        "PORT": "",                             # Set to empty string for default. Not used with sqlite3.
    }
}

then I have this injection code for Heroku:

import dj_database_url
DATABASES = {'default': dj_database_url.config(default='postgres://localhost')}

Heroku gives you a Postgres database by default. To completely remove it run:

heroku addons:remove heroku-postgresql:dev

Then to create a new one:

heroku addons:add heroku-postgresql:dev

If it does not automatically promote this to your main DB (you should a config var DATABASE_URL if so) then run:

heroku pg:promote HEROKU_POSTGRESQL_COLORHERE
