How to list all Rails 3 rake tasks
If you run the “classic” rake -T, only the tasks with descriptions will be appear, for instance:
$ rake -T db
Will display something like:
rake db:create # Create the database from config/database.yml for the current Rails.env (use db:create:all to create all dbs in the config) rake db:drop # Drops the database for the current Rails.env (use db:drop:all to drop all databases) rake db:fixtures:load # Load fixtures into the current environment's database. rake db:migrate # Migrate the database (options: VERSION=x, VERBOSE=false). rake db:migrate:status # Display status of migrations rake db:rollback # Rolls the schema back to the previous version (specify steps w/ STEP=n). rake db:schema:dump # Create a db/schema.rb file that can be portably used against any DB supported by AR rake db:schema:load # Load a schema.rb file into the database rake db:seed # Load the seed data from db/seeds.rb rake db:setup # Create the database, load the schema, and initialize with the seed data (use db:reset to also drop the db first) rake db:structure:dump # Dump the database structure to db/structure.sql. Specify another file with DB_STRUCTURE=db/my_structure.sql rake db:version # Retrieves the current schema version number
But the rake task db:test:prepare is not listed. If you want to list all the tasks, no matter if have a description or not, use this:
$ rake -P
And if you want to avoid the noise, use the following to show the names of all Rake tasks:
$ rake -P | grep rake
