¿Por qué rake db: migrate: reset no listado en rake-T? (6)

¿Por qué algunas tareas de rake no aparecen en la lista de rake -T ? Al igual que db:migrate:reset ? Puedo ejecutarlo sin ningún problema, pero ¿por qué no aparece en la lista? ¿Hay alguna manera de obtener una lista completa de tareas de rake?

% rake -T (in /home/zeus/projects/my_project) rake about # List versions of all Rails frameworks and the environment 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 an SQL file rake db:version # Retrieves the current schema version number rake doc:app # Generate docs for the app -- also availble doc:rails, doc:guides, doc:plugins (options: TEMPLATE=/rdoc-template.rb, TITLE="Custom Title") rake erd # Generate an Entity-Relationship Diagram based on your models rake log:clear # Truncates all *.log files in log/ to zero bytes rake middleware # Prints out your Rack middleware stack rake notes # Enumerate all annotations (use notes:optimize, :fixme, :todo for focus) rake notes:custom # Enumerate a custom annotation, specify with ANNOTATION=CUSTOM rake rails:template # Applies the template supplied by LOCATION=/path/to/template rake rails:update # Update both configs and public/javascripts from Rails (or use just update:javascripts or update:configs) rake routes # Print out all defined routes in match order, with names. rake secret # Generate a crytographically secure secret key (this is typically used to generate a secret for cookie sessions). rake spec # Run all specs in spec directory (excluding plugin specs) rake spec:acceptance # Run the code examples in spec/acceptance rake spec:controllers # Run the code examples in spec/controllers rake spec:helpers # Run the code examples in spec/helpers rake spec:lib # Run the code examples in spec/lib rake spec:mailers # Run the code examples in spec/mailers rake spec:models # Run the code examples in spec/models rake spec:rcov # Run all specs with rcov rake spec:requests # Run the code examples in spec/requests rake spec:routing # Run the code examples in spec/routing rake spec:views # Run the code examples in spec/views rake stats # Report code statistics (KLOCs, etc) from the application rake test # Runs test:units, test:functionals, test:integration together (also available: test:benchmark, test:profile, test:plugins) rake test:recent # Run tests for recenttest:prepare / Test recent changes rake test:uncommitted # Run tests for uncommittedtest:prepare / Test changes since last checkin (only Subversion and Git) rake time:zones:all # Displays all time zones, also available: time:zones:us, time:zones:local -- filter with OFFSET parameter, e.g., OFFSET=-6 rake tmp:clear # Clear session, cache, and socket files from tmp/ (narrow w/ tmp:sessions:clear, tmp:cache:clear, tmp:sockets:clear) rake tmp:create # Creates tmp directories for sessions, cache, sockets, and pids

Como seguimiento de la respuesta de Thomas Obermüller, dado que el indicador -T toma un argumento posicional, para obtener solo las tareas del espacio de nombres ''db'' (al menos con el rastrillo 10.0.3) debe hacer: rake -T db -A

Para el usuario de Windows, usted hace este rake -P | encontrar "rake"

Puede usar rake -P | grep rake rake -P | grep rake para mostrar los nombres de todas las tareas de Rake.

También puede usar rake db -T -A para mostrar todas las tareas, incluso las no comentadas. Como referencia, estos modificadores hacen lo siguiente:

-T, --tasks [PATTERN] Display the tasks (matching optional PATTERN) with descriptions, then exit. -A, --all Show all tasks, even uncommented ones (in combination with -T or -D)
