rails-destroy: Destroy a migration that creates Posts.

rails

$ rails destroy migration ${CreatePosts}

try on your machine

The "rails destroy" command is used in Ruby on Rails to undo or delete certain resources that were previously generated by Rails generators. It is especially useful when you want to remove a specific migration file.

In this specific command, "rails destroy migration ${CreatePosts}", you are instructing Rails to delete the migration file named "CreatePosts".

Migrations in Ruby on Rails are used to manage changes to your database schema over time. They allow you to create, modify, or delete database tables and columns. When you generate a migration using the "rails generate" command, Rails creates a migration file with a specific name.

However, if you created a migration called "CreatePosts" and want to undo it, you would use the "rails destroy migration" command followed by the name of the migration file. The command will find and delete the "CreatePosts" migration file, effectively rolling back any changes associated with that migration.
