Question

def show
    #find parent call_flow
    @call_flow = CallFlow.where('dnis' => params[:dnis]).first

    if @call_flow.nil?
        @response = ["no result"]
    else
        #find first routable options (should be a message)
        @call_flow_options = @call_flow.routable_type.constantize.find(@call_flow.routable_id).options

        #if there is a route after the first route, find it
        unless @call_flow_options.first.target_routable_type.nil?
            @target_routable = @call_flow_options.first.target_routable_type.constantize.find(@call_flow_options.first.target_routable_id).options
            @call_flow_options.to_a.push(@target_routable.to_a)
        end
        @response = @call_flow.to_a.push(@call_flow_options)
    end
    respond_with @response 

end

我收回数据但浏览器无法将其识别为JSON，因为所有"双引号都替换为"。

如果您希望整个响应都是JSON（而不是使用JSON的HTML / JavaScript），您可以这样做：

render :json => @response

Rails控制器返回转义的JSON
