Rails 渲染 json 包括带参数的方法

问题描述

我在方法控制器中有这个渲染:

I have this render in a method controller:

render :json => @boats, :include => {:port => {:only => [:id, :name], :include => {:city => {:only => [:id, :name], :methods => :translatedCity}}}}

但是模型中的 translatedCity 方法应该接受语言参数.

but translatedCity method in the model should accept language parameter.

  def translatedCity
    language = params[:language]
    puts "translatedCity.language=" + language
    city = TranslationService.translateCity(self.city_id, language)
    return city.element_translation
  end

我在控制器中有参数.有没有办法把这个参数传递给模型中的方法?

I have the parameter in the controller. Is there any way to pass this parameter to the method in the model?

推荐答案

所有答案都很好！

我只是做了类似的事情:

I just did something like:

在控制器中:

boat.port.language = params[:language]

在模型中:

attr_accessor :language
  @language

  def translatedCity
    city = TranslationService.translateCity(self.city_id, language)
    return city.element_translation
  end

你怎么看?
