module ActiveScaffold::Configurable

Exposes a configure method that accepts a block and runs all contents of the block in two contexts, as opposed to the normal one. First, everything gets evaluated as part of the object including Configurable. Then, as a failover, missing methods and variables are evaluated in the original binding of the block.

Note that this only works with “barewords”. Constants, instance variables, and class variables are not currently supported in both contexts.

May add the given functionality at both the class and instance level. For the former, use extend, and for the latter, use include.

Public Instance Methods

configure(&configuration_block) click to toggle source
# File lib/active_scaffold/configurable.rb, line 8
def configure(&configuration_block)
  return unless configuration_block
  @configuration_binding = configuration_block.binding.eval('self')
  ret = instance_exec(self, &configuration_block)
  @configuration_binding = nil
  ret
end
method_missing(name, *args) click to toggle source

this method will surely need tweaking. for example, i'm not sure if it should call super before or after it tries to eval with the binding.

Calls superclass method
# File lib/active_scaffold/configurable.rb, line 17
def method_missing(name, *args)
  super
rescue NoMethodError, NameError
  if @configuration_binding.nil?
    raise
  else
    @configuration_binding.send(name, *args)
  end
end
