Instance Method Details

#adapter(options) ⇒ Object #adapter ⇒ Hash

Adapter configuration. The application will instantiate adapter instance based on this configuration.

The given options must have key pairs :type and :uri If it isn’t, at the runtime the framework will raise a ‘ArgumentError`.

This is part of a DSL, for this reason when this method is called with an argument, it will set the corresponding instance variable. When called without, it will return the already set value, or the default.

Examples:

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
    configure do
      adapter :sql, 'sqlite3://uri'
    end
  end
end

Bookshelf::Application.configuration.adapter
  # => [:sql, 'sqlite3://uri']

Overloads:

  • #adapter(options) ⇒ Object

    Sets the given type and uri

    Parameters:

    • options (Hash) —

      a set of options for adapter

  • #adapter ⇒ Hash

    Gets the value

    Returns:

    • (Hash) —

      adapter options

#controller ⇒ Hanami::Config::FrameworkConfiguration

It lazily collects all the low level settings for Hanami::Controller’s configuration and applies them when the application is loaded.

NOTE: This forwards all the configurations to Hanami::Controller, without checking them. Before to use this feature, please have a look at the current Hanami::Controller version installed.

NOTE: This may override some configurations of your application.

Examples:

Define a setting

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
    configure do
      controller.default_request_format :json
    end
  end
end

Override a setting

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
    configure do
      handle_exceptions            false
      controller.handle_exceptions true
    end
  end
end

# Exceptions will be handled

Returns:

#controller_pattern(value) ⇒ Object #controller_pattern ⇒ String

Defines a relative pattern to find controllers.

Hanami supports multiple architectures (aka application structures), this setting helps to understand the namespace where to find applications’ controllers and actions.

By default this equals to "Controllers::%{controller}::%{action}" That means controllers must be structured like this: Bookshelf::Controllers::Dashboard::Index, where Bookshelf is the application module, Controllers is the first value specified in the pattern, Dashboard the controller and Index the action.

This pattern MUST always contain "%{controller}" and %{action}. This pattern SHOULD be used accordingly to #view_pattern value.

This is part of a DSL, for this reason when this method is called with an argument, it will set the corresponding instance variable. When called without, it will return the already set value, or the default.

Examples:

Getting the value

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
    configure do
      routes do
        get '/', to: 'dashboard#index'
      end
    end
  end

  module Controllers::Dashboard
    class Index
      include Bookshelf::Action

      def call(params)
        # ...
      end
    end
  end
end

Bookshelf::Application.configuration.controller_pattern
  # => "Controllers::%{controller}::%{action}"

# All the controllers MUST live under Bookshelf::Controllers

# GET '/' # => Bookshelf::Controllers::Dashboard::Index

Setting the value

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
    configure do
      controller_pattern "%{controller}Controller::%{action}"

      routes do
        get '/', to: 'dashboard#index'

  end
end

Bookshelf::Application.configuration.controller_pattern
  # => "%{controller}Controller::%{action}"

# All the controllers are directly under the Bookshelf module

#model ⇒ Hanami::Config::FrameworkConfiguration

It lazily collects all the low level settings for Hanami::Model’s configuration and applies them when the application is loaded.

NOTE: This forwards all the configurations to Hanami::Model, without checking them. Before to use this feature, please have a look at the current Hanami::Model version installed.

NOTE: This may override some configurations of your application.

Examples:

Define a setting

require 'hanami'
require 'hanami/model'

module Bookshelf
  class Application < Hanami::Application
    configure do
      model.adapter :sql, 'sqlite://db/bookshelf_development'
    end
  end
end

Override a setting

require 'hanami'
require 'hanami/model'

module Bookshelf
  class Application < Hanami::Application
    configure do
      adapter       :sql, 'postgres://localhost/database'
      model.adapter :sql, 'sqlite://db/bookshelf_development'
    end
  end
end

# The sqlite adapter will override the SQL one

Returns:

#port(value) ⇒ Object #scheme ⇒ String

The URI port for this application. This is used by the router helpers to generate absolute URLs.

By default this value is ‘2300`.

This is part of a DSL, for this reason when this method is called with an argument, it will set the corresponding instance variable. When called without, it will return the already set value, or the default.

Examples:

Getting the value

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
  end
end

Bookshelf::Application.configuration.port # => 2300

Setting the value

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
    configure do
      port 8080
    end
  end
end

Bookshelf::Application.configuration.port # => 8080

Overloads:

  • #port(value) ⇒ Object

    Sets the given value

    Parameters:

    • value (#to_int) —

      the URI port

    Raises:

    • (TypeError) —

      if the given value cannot be coerced to Integer

  • #scheme ⇒ String

    Gets the value

    Returns:

    • (String)

#root(value) ⇒ Object #root ⇒ Pathname

The root of the application

By default it returns the current directory, for this reason, **all the commands must be executed from the top level directory of the project**.

If for some reason, that constraint above cannot be satisfied, please configure the root directory, so that commands can be executed from everywhere.

This is part of a DSL, for this reason when this method is called with an argument, it will set the corresponding instance variable. When called without, it will return the already set value, or the default.

Examples:

Getting the value

require 'hanami'

  end
end

Bookshelf::Application.configuration.root # => #<Pathname:/path/to/root>

Setting the value

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
    configure do
      root '/path/to/another/root'
    end
  end
end

Overloads:

  • #root(value) ⇒ Object

    Sets the given value

    Parameters:

    • value (String, Pathname, #to_pathname) —

      The root directory of the app

  • #root ⇒ Pathname

    Gets the value

    Returns:

    • (Pathname)

    Raises:

#sessions(adapter, options) ⇒ Object #sessions(false) ⇒ Object #sessions ⇒ Hanami::Config::Sessions

Configure sessions Enable sessions (disabled by default).

This is part of a DSL, for this reason when this method is called with an argument, it will set the corresponding instance variable. When called without, it will return the already set value, or the default.

Given Class as adapter it will be used as sessions middleware. Given String as adapter it will be resolved as class name and used as sessions middleware. Given Symbol as adapter it is assumed it’s name of the class under Rack::Session namespace that will be used as sessions middleware (e.g. :cookie for Rack::Session::Cookie).

By default options include domain inferred from host configuration, and secure flag inferred from scheme configuration.

Examples:

Getting the value

require 'hanami'

module Bookshelf
  class Application < Hanami::Application

#view_pattern(value) ⇒ Object #controller_pattern ⇒ String

Defines a relative pattern to find views:.

Hanami supports multiple architectures (aka application structures), this setting helps to understand the namespace where to find applications’ views:.

By default this equals to "Views::%{controller}::%{action}" That means views must be structured like this: Bookshelf::Views::Dashboard::Index, where Bookshelf is the application module, Views is the first value specified in the pattern, Dashboard a module corresponding to the controller name and Index the view, corresponding to the action name.

This pattern MUST always contain "%{controller}" and %{action}. This pattern SHOULD be used accordingly to #controller_pattern value.

This is part of a DSL, for this reason when this method is called with an argument, it will set the corresponding instance variable. When called without, it will return the already set value, or the default.

Examples:

Getting the value

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
    configure do
      routes do
        get '/', to: 'dashboard#index'
      end
    end
  end

  module Views
    module Dashboard
      class Index
        include Bookshelf::View
      end
    end
  end
end

Bookshelf::Application.configuration.view_pattern
  # => "Views::%{controller}::%{action}"

# All the views MUST live under Bookshelf::Views

# GET '/' # => Bookshelf::Views::Dashboard::Index

Setting the value

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
    configure do
      view_pattern "%{controller}::%{action}"

      routes do
        get '/', to: 'dashboard#index'
      end
    end
  end

  module Dashboard
    class Index
      include Bookshelf::View
    end
  end
end

Bookshelf::Application.configuration.view_pattern
  # => "%{controller}::%{action}"

# All the views are directly under the Bookshelf module

# GET '/' # => Bookshelf::Dashboard::Index

Setting the value for a top level name structure

require 'hanami'

module Bookshelf
  class Application < Hanami::Application
    configure do
      view_pattern "%{controller}::%{action}"

      routes do
        get '/', to: 'dashboard#index'

  # => "%{controller}::%{action}"

# All the views: are at the top level namespace

# GET '/' # => Dashboard::Index

Overloads:
