Overview

An Engine with the responsibility of coordinating the whole boot process.

Initialization

Application is responsible for executing all railties and engines initializers. It also executes some bootstrap initializers (check Bootstrap) and finishing initializers, after all the others are executed (check Finisher).

Configuration

Besides providing the same configuration as Engine and Railtie, the application object has several specific configurations, for example enable_reloading, consider_all_requests_local, #filter_parameters, logger, and so forth.

Check Configuration to see them all.

Routes

The application object is also responsible for holding the routes and reloading routes whenever the files change in development.

Middlewares

The Application is also responsible for building the middleware stack.

Booting process

The application is also responsible for setting up and executing the booting process. From the moment you require config/application.rb in your app, the booting process goes like this:

require "config/boot.rb" to set up load paths.
require railties and engines.
Define application as class {MyApp::Application} < Rails::Application.
Run config.before_configuration callbacks.
Load config/environments/ENV.rb.
Run config.before_initialize callbacks.
Run Railtie#initializer defined by railties, engines, and application. One by one, each engine sets up its load paths and routes, and runs its config/initializers/* files.
Custom Railtie#initializers added by railties, engines, and applications are executed.
Build the middleware stack and run to_prepare callbacks.
Run config.before_eager_load and #eager_load! if eager_load is true.
Run config.after_initialize callbacks.

#deprecators

#encrypted(path, key_path: "config/master.key", env_key: "RAILS_MASTER_KEY")

Returns an ::ActiveSupport::EncryptedConfiguration instance for an encrypted file. By default, the encryption key is taken from either ENV["RAILS_MASTER_KEY"], or from the config/master.key file.

my_config = Rails.application.encrypted("config/my_config.enc")

my_config.read
# => "foo:\n  bar: 123\n"

def generators(&blk)

#initializer(name, opts = {}, &block)

Sends the initializers to the initializer method defined in the Initializable module. Each Application class has its own set of initializers, as defined by the Initializable module.

def initializer(name, opts = {}, &block)

end

#key_generator(secret_key_base = self.secret_key_base)

Returns a key generator (ActiveSupport::CachingKeyGenerator) for a specified #secret_key_base. The return value is memoized, so additional calls with the same #secret_key_base will return the same key generator instance.

[ GitHub ]

# File 'railties/lib/rails/application.rb', line 161


def key_generator(secret_key_base = self.secret_key_base)
  # number of iterations selected based on consultation with the google security
  # team. Details at https://github.com/rails/rails/pull/6952#issuecomment-7661220
  @key_generators[secret_key_base] ||= ActiveSupport::CachingKeyGenerator.new(
    ActiveSupport::KeyGenerator.new(secret_key_base, iterations: 1000)
  )
end

#message_verifier(verifier_name)

Returns a message verifier object.

This verifier can be used to generate and verify signed messages in the application.

It is recommended not to use the same verifier for different things, so you can get different verifiers passing the verifier_name argument.

Parameters

verifier_name - the name of the message verifier.

Examples

message = Rails.application.message_verifier('sensitive_data').generate('my sensible data')
Rails.application.message_verifier('sensitive_data').verify(message)
# => 'my sensible data'

See the ::ActiveSupport::MessageVerifier documentation for more information.

[ GitHub ]

# File 'railties/lib/rails/application.rb', line 222


def message_verifier(verifier_name)
  message_verifiers[verifier_name]
end

#message_verifiers

Returns a message verifier factory (ActiveSupport::MessageVerifiers). This factory can be used as a central point to configure and create message verifiers (ActiveSupport::MessageVerifier) for your application.

By default, message verifiers created by this factory will generate messages using the default ::ActiveSupport::MessageVerifier options. You can override these options with a combination of ActiveSupport::MessageVerifiers#clear_rotations and ActiveSupport::MessageVerifiers#rotate. However, this must be done prior to building any message verifier instances. For example, in a before_initialize block:

# Use `url_safe: true` when generating messages
config.before_initialize do |app|
  app.message_verifiers.clear_rotations
  app.message_verifiers.rotate(url_safe: true)
end

Message verifiers created by this factory will always use a secret derived from #secret_key_base when generating messages. clear_rotations will not affect this behavior. However, older #secret_key_base values can be rotated for verifying messages:

# Fall back to old {secret_key_base} when verifying messages
config.before_initialize do |app|
  app.message_verifiers.rotate(secret_key_base: "old secret_key_base")
end

[ GitHub ]

# File 'railties/lib/rails/application.rb', line 197


def message_verifiers
  @message_verifiers ||=
    ActiveSupport::MessageVerifiers.new do |salt, secret_key_base: self.secret_key_base|
      key_generator(secret_key_base).generate_key(salt)
    end.rotate_defaults
end

#rake_tasks(&block)

If you try to define a set of Rake tasks on the instance, these will get passed up to the Rake tasks defined on the application’s class.

[ GitHub ]

# File 'railties/lib/rails/application.rb', line 338


def rake_tasks(&block)
  self.class.rake_tasks(&block)
end

#reload_routes!

Reload application routes regardless if they changed or not.

[ GitHub ]

# File 'railties/lib/rails/application.rb', line 153


def reload_routes!
  routes_reloader.reload!
end

#runner(&blk)

# File 'railties/lib/rails/application.rb', line 351


def runner(&blk)
  self.class.runner(&blk)
end

#sandbox (rw) Also known as: #sandbox?

[ GitHub ]

# File 'railties/lib/rails/application.rb', line 100


attr_accessor :assets, :sandbox

#secret_key_base

The secret_key_base is used as the input secret to the application’s key generator, which in turn is used to create all ::ActiveSupport::MessageVerifier and ::ActiveSupport::MessageEncryptor instances, including the ones that sign and encrypt cookies.

In development and test, this is randomly generated and stored in a temporary file in tmp/local_secret.txt.

You can also set ENV["SECRET_KEY_BASE_DUMMY"] to trigger the use of a randomly generated secret_key_base that’s stored in a temporary file. This is useful when precompiling assets for production as part of a build step that otherwise does not need access to the production secrets.

Dockerfile example: RUN SECRET_KEY_BASE_DUMMY=1 bundle exec rails assets:precompile.

In all other environments, we look for it first in ENV["SECRET_KEY_BASE"], then credentials.secret_key_base, and finally secrets.secret_key_base. For most applications, the correct place to store it is in the encrypted credentials file.
