发出可表示的传递选项-参数数目错误（1代表0）

Question

I'm trying to use passing options in representers gem

I have a decorator:

class ProductDecorator < Representable::Decorator
  include Representable::JSON

  property :code
  property :name

  property :store_id, getter: lambda { |opts| opts[:store_id] },
    type: Integer

  property :url, decorator_scope: true, getter: lambda { |options|
    File.join(options.fetch(:site,""), url)
  }, type: String

  def url
    File.join(represented.path ,"p")
  end

end

But when I try to pass my options using:

ProductDecorator.new(product).
        to_hash(store_id: 1, site: "my_url")

I'm getting the message wrong number of arguments (1 for 0)

I've tried many options, but I could find what's going on.

Answer 1

to_hash method doesn't take arguments that is the reason for error.

I suppose you meant to do something like:

ProductDecorator.new(product).to_json(store_id: 1, site: "my_url")

Or you can also go for:

JSON.parse(ProductDecorator.new(product).
to_json(store_id: 1, site: "my_url")).symbolize_keys
