从定义“方法”界定的方法中得出的表面表面的正当论点没有得到支持
原标题:Implicit argument passing of super from method defined by define_method() is not supported

Agile Web Development withrails (third edition) page 537 - 541, it has “Custom Form Buildingers” Code as follows:

  class TaggedBuilder < ActionView::Helpers::FormBuilder
    # <p> # <label for="product_description">Description</label><br/> # <%= form.text_area  description  %> #</p>
    def self.create_tagged_field(method_name) 
      define_method(method_name) do |label, *args|
        @template.content_tag("p" , @template.content_tag("label" , label.to_s.humanize, 
        :for => "#{@object_name}_#{label}") + "<br/>" + super)
      end
    end
    field_helpers.each do |name| 
      create_tagged_field(name)
    end 
  end

该法典与Rub.1.9.1条不合作。 错误如下:

<代码>从定义“方法”界定的方法中转出超级表面的简单论点没有得到支持。 明确列举所有论点。 (行动意见:TemplateError)

我的问题是:我应该对法典作什么改动以解决这个问题?

问题回答

在定义中,我遇到了这一问题,即:在没有任何理由的情况下采取的方法。

define_method :"#{info_type}_info" do

  info = super
  .......

end

这个问题依然存在。 我必须明确指出:

define_method :"#{info_type}_info" do

  info = super()
  .......

end
