Disabling Rails' db:reset task

Question

To avoid an accidental 'rake db:reset' on our production environments, I was thinking about disabling 'rake db:reset' and related tasks that drop the database in the production environment. Is there an easy way to do this, or do I have to redefine the rake task?

Is there a better alternative?

Answer 1

In your Rake file you can add

Rake.application.instance_variable_get('@tasks').delete('db:reset')

and the command is not available any more. If you want to disable multiple commands, put it in a remove_task method for readability.

But a better alternative seem to just not type the rake db:reset command, which is not something you'd accidentally type.

Having a nice backup of your (production) database is also a better solution I suppose.

Answer 2

Put this in lib/tasks/db.rake:

if Rails.env == 'production'
  tasks = Rake.application.instance_variable_get '@tasks'
  tasks.delete 'db:reset'
  tasks.delete 'db:drop'
  namespace :db do
    desc 'db:reset not available in this environment'
    task :reset do
      puts 'db:reset has been disabled'
    end
    desc 'db:drop not available in this environment'
    task :drop do
      puts 'db:drop has been disabled'
    end
  end
end
