生成一个Padrino应用之后，在应用文件夹内没有一个Rakefile（Rake任务）；实际上，我们可以使用很多Padrino内建的Rake任务：
padrino rake
# or for a list of tasks
padrino rake -T
如果需要定制任务，可以将其加入下列文件中：
Padrino会自动搜索这些目录内的任何 *.rake 文件。
Padrino默认会执行一些很有用的任务。
同其他一些框架一样，我们使用一些 :environment 任务加载我们在这些 environment 下的一些应用。例如：
# 这是一个定制的任务
# 文件位置：task/version.rake
task :version => :environment do
puts Padrino.version
end
我们已经提供一个列出应用内所有具名路由的任务。
padrino rake routes
上面命令将会应用内所有具名路由：
Application: core
URL REQUEST PATH
(:guides, :search) GET /guides/search
(:guides, :index) GET /guides
(:guides, :show) GET /guides/:id
Application: foo
(:blog, :index) GET /blog
(:blog, :show) GET /blog/:id
当使用Padrino进行测试的时候，可以使用内建的 padrino rake test 或者rspec的 padrino rake spec.
padrino rake test # => for bacon, riot, shoulda
padrino rake spec # => for rspec
可以定制 test/test.rake 或者 spec/spec.rake
您可以通过程序自动生成模型的本地化 yml 文件：
padrino rake locale:models
具体细节查看 本地化章节。
Padrino针对不同的对象关系模型（ORM）都有内建的任务支持，例如 DataMapper ， ActiveRecord， Sequel， Mongomapper，和 Mongoid 都有针对性的命令。
注意：我们针对不同的ORM使用不同的命名空间，因此Padrino可以在一个应用中挂载不同的程序，每个程序都可以使用自己的ORM而互不影响。例如在一个大型应用内，这个程序使用了DataMapper，而另一个程序却使用了 ActiveRecord/MongoMapper/Couch/Sequel。我们就是使用这种方式防止冲突发生。
rake ar:abort_if_pending_migrations # Raises an error if there are pending migrations.
rake ar:auto:upgrade # Uses schema.rb to auto-upgrade.
rake ar:charset # Retrieves database charset.
rake ar:collation # Retrieves databsae collation.
rake ar:create # Creates the database as defined in config/database.yml
rake ar:create:all # Creates local databases as defined in config/database.yml
rake ar:drop # Drops the database for the current Padrino.env
rake ar:drop:all # Drops local databases defined in config/database.yml
rake ar:forward # Pushes the schema to the next version.
rake ar:migrate # Migrates the database through scripts in db/migrate.
rake ar:migrate:down # Runs the "down" for a given migration VERSION.
rake ar:migrate:redo # Rollbacks current migration and migrates up to version
rake ar:migrate:reset # Resets your database using your migrations.
rake ar:migrate:up # Runs the "up" for a given migration VERSION NUMBER
rake ar:reset # Drops and recreates the database using db/schema.rb.
rake ar:rollback # Rolls back the schema to previous schema version.
rake ar:schema:dump # Creates a portable db/schema.rb file.
rake ar:schema:load # Loads a schema.rb file into the database.
rake ar:schema:to_migration # Creates a migration from schema.rb
rake ar:schema:to_migration_with_reset # Creates a migration and resets the migrations log.
rake ar:setup # Creates the database, loads the schema, and seeds data.
rake ar:structure:dump # Dumps the database structure to a SQL file.
rake ar:version # Retrieves the current schema version number.
rake ar:auto:upgrade
这是一个对于不爱使用数据版本迁移（例如我）的人来说是超酷和超有用的工具。这有一个复制版本在 auto_migrations
实际上，不写数据版本迁移，也可以直接编辑 schema.rb 然后运行 padrino rake ar:auto:upgrade 来进行一次无伤大雅的数据迁移。
rake dm:auto:migrate # Performs an automigration (resets your db data)
rake dm:auto:upgrade # Performs a non destructive automigration
rake dm:create # Creates the database
rake dm:drop # Drops the database (postgres and mysql only)
rake dm:migrate # Migrates the database to the latest version
rake dm:migrate:down[version] # Migrates down using migrations
rake dm:migrate:up[version] # Migrates up using migrations
rake dm:reset # Drops the database, and migrates from scratch
rake dm:setup # Create the database migrate and initialize with the seed data
rake sq:migrate:auto # Perform automigration (reset your db data)
rake sq:migrate:to[version] # Perform migration up/down to VERSION
rake sq:migrate:up # Perform migration up to latest migration available
rake sq:migrate:down # Perform migration down (erase all data)
rake mm:translate # Generates .yml files for I18n translations
从0.9.21版本开始提供
rake mi:drop # Drops all the collections for the database for the current environment
rake mi:create_indexes # Create the indexes defined on your mongoid models
rake mi:objectid_convert # Convert string objectids in mongo database to ObjectID type
rake mi:cleanup_old_collections # Clean up old collections backed up by objectid_convert
像Rails一样，我们可议使用 db/seeds.rb 来输入数据到数据库，这是一个示例（来自padrino-admin）：
email = shell.ask "Which email do you want use for loggin into admin?"
password = shell.ask "Tell me the password to use:"
shell.say ""
account = Account.create(:email => email, :password => password,
:password_confirmation => password, :role => "admin")
if account.valid?
shell.say "Perfect! Your account was created."
shell.say ""
shell.say "Now you can start your server with padrino start and then login into /admin with:"
shell.say " email: #{email}"
shell.say " password: #{password}"
shell.say ""
shell.say "That's all!"
else
shell.say "Sorry but some thing went worng!"
shell.say ""
account.errors.full_messages.each { |m| shell.say " - #{m}" }
end
