Netzke::Configuration::ClassMethods

Public Instance Methods

class_config_option(name, default_value) click to toggle source

Used to define class-level configuration options for a component, e.g.:

class Netzke::Basepack::GridPanel < Netzke::Base
  class_config_option :rows_reordering_available, true
  ...
end

This can later be set in the application configuration:

module RailsApp
  class Application < Rails::Application
    config.netzke.basepack.grid_panel.rows_reordering_available = false
    ...
  end
end

Configuration options can be accessed as class attributes:

Netzke::Basepack::GridPanel.rows_reordering_available # => false
# File lib/netzke/configuration.rb, line 55
def class_config_option(name, default_value)
  value = if app_level_config.has_key?(name.to_sym)
    if app_level_config[name.to_sym].is_a?(Hash) && default_value.is_a?(Hash)
      default_value.deep_merge(app_level_config[name.to_sym])
    else
      app_level_config[name.to_sym]
    end
  else
    default_value
  end
  class_attribute(name.to_sym)
  self.send("#{name}=", value)
end

  if block_given?
    define_method(:"weak_#{level}_options", &block)

      config_hash
    end
  end
end
