Instance Method Details

#do_assign(params, instance) ⇒ Object

Set the arguments on an instance of a given configuration class. This uses the safe_assign method that should be present in all configuration classes to determine which values are allowed to be passed via form fields (i.e. which ones are subject to validation)

def do_assign(params, instance)
  safe = instance.safe_assign

  params.each do |param, value|
    if safe.include? param.intern
      instance.send((param + '=').intern, value)
    end
  end
end

#extract_class_args(params, target_class) ⇒ Object

Extract arguments from a set of form data that are intended to go to a specific network configuration class. These fields have names of the form ‘ClassName/field_name’; this function returns a hash in the form { ‘field_name’ => ‘value } containing the configuration arguments.
