Heroku Drop Table Rails Help

Question

I am using Ruby on Rails and I no longer need my table Order so I deleted it using SQLite manager.. How can I make the table deletion take place in heroku?

Answer 1

In case you don't want to create a migration to drop table and cant rollback the previous migrations because you don't want to lose the data in the tables created after that migration, you could use following commands on heroku console to drop a table:

$ heroku console
Ruby console for heroku-project-name
>> ActiveRecord::Migration.drop_table(:orders)

Above command will drop the table from your heroku database. You can use other methods like create_table, add_column, add_index etc. in the ActiveRecord::Migration module to manipulate database without creating and running a migration. But be warned that this will leave a mess behind in the schema_migrations table created by Rails for managing migration versions.

This could only be useful if your application is still under development and you don't want to lose the data you have added on remote staging server on heroku.
