在 Rails 中渲染 JSON 时包含关联模型
问题描述：
现在我有这条线:
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.
如何在渲染程序时包含公司名称?
How can I include the company name when rendering Programs?
答
这样的事情应该可行:
render :json => @programs, :include => {:insurer => {:only => :name}}, :except => [:created_at, :updated_at]
