How do you rake a Heroku database?

I have an application on Heroku. However, whenever I change my database locally and then push the changes to the application, the database doesn't not change.

I realized that I need to run a rake on the Heroku database. However when I try heroku rake db:migrate I get the following error.

rake aborted! uninitialized constant Rake::DSL`

How do I solve this problem?

I've been improvising with heroku db:push, but that will not be able to hold because it deletes the current database.

Solution

  • If you are using the new Cedar Stack, you should use

    heroku run rake db:migrate
