Question

可以帮我识别并解决为什么我无法看到我的us_show.html.erb模板吗？这是我在控制器中的功能：

def update_info

    respond_to do |format|

        if @traveler_info.update_attributes(traveler_info_params)
            flash[:notice] = 'Provided information has been submitted successfully.'
            # @traveler_info = TravelerInfo.where(user_id:current_user.id).first
            if true#@traveler_info.country == 'US'
                format.html { render :action => :us_show }
                format.js{ render :action => :us_show }
            else
                format.html {  render :action => :non_us_show}
                format.js{ render :action => :non_us_show }
            end
            # render :index, status: :ok, location: @contact_info
            # format.json { render action: 'edit', status: :created, location:    @traveler_info }
            format.js { render action: 'edit', status: :created, location: :us_show }
        else
            flash[:error] = "Provided information couldn't be saved. Please try again"
            format.html { render :action => :edit }
            format.json { render :json => @trav_info.errors.full_messages.join("</br>"), :status => :bad_request }
        end
    end     
end

这是我的服务器日志

它说它已成功呈现，但事实并非如此。

如果您查看日志，则说

通过Traveler :: PassportController＃update处理为JS

现在在你的update方法中，这行被执行，因为格式是JS

format.js{ render :action => :us_show }

现在让我们再看一下你的日志。你有

呈现旅行者/护照/ us_show.html.erb（0.1ms）

注意它是.html而不是.js所以在你的us_show动作中你不是在处理一个js请求。所以，虽然您的模板正在呈现 ，但由于它是一个js请求，所以服务器不知道如何处理它。

<强>修正

您最好渲染部分而不是动作。将模板中的代码分离为部分代码，然后按js渲染。 您可以这样做：

format.js{} #this will make rails look for a file called update_info.js.erb in app/views/controller_name directory

#update_info.js.erb
("#some_parent_id").html(<%=j render "your_partial_name" %>);

您应该结帐Working with JavaScript in Rails

Rails：HTML.erb页面不呈现，服务器说，它呈现
