ActiveRecord migrations from the console
If you ever run into the situation where one migration doesn’t complete sucessfully, and you’re stuck with a column in a table or a new table, so you can’t drop the migration or execute the migration again, you can always call the migration methods from the console like this:
ActiveRecord::Migration.drop_table :table_name ActiveRecord::Migration.remove_column :table_name, :column_name
Hopefully this will help you when you’re developing your migrations.
