在Rails中呈现JSON时包括关联的模型

问题描述：

现在我有这行:

 render json: @programs, :except => [:created_at, :updated_at]

但是，由于程序属于公司，我想显示公司名称而不是公司ID.

However, since a Program belongs_to a Company I would like to show the Company name instead of the Company Id.

在渲染程序时如何包含公司名称?

How can I include the company name when rendering Programs?

答

类似的方法应该起作用:

Something like this should work:

render :json => @programs, :include => {:insurer => {:only => :name}}, :except => [:created_at, :updated_at]
