Rails：如何在控制器中呈现其他动作，在js中不在html中？

Question

I have two actions in my controller :

def find
  @item = Item.find(params[:id])
  render 'result', :id => @item.id
end

def result
  @item = Item.find(params[:id])
  respond_to do |format|
    format.js
  end
end

The issue in that I call first the find action, then it calls the result action but in the html format. So the 'format.js` is never triggered.

How can render, at the end of the find action, the result action in the js format ?

Thanks a lot !

Answer 1

在find方法中尝试这个。

render 'result', :id => @item.id, :format => :js

Answer 2

Try this

<%= render 'components/activity-slider', populer_packages: @populer_packages %>

    components/activity-slider

    <div class="slider sliderSecondary activitiesSlider">
    <% populer_packages.each do |package| %>
        <a href="#" class="sliderGrid ">
          <div class="sliderCont">
            <div class="sliderGradient"></div>
            <div class="sliderThumb">
              <div class="sliderImgWrap">
                <%= image_tag "#{package.image}", class: "img-fluid sliderImg" %>
                <div class="overlayCaptionCont">
                  <div class="overlayCaptionWrap">
                    <div class="overlayCaption">
                      <ul class="list-unstyled captionList">
                        <li>test</li>
                      </ul>
                    </div>
                  </div>
                </div>
              </div>
            </div>
          </div>
        </a>
      <% end %>
    </div>

Answer 3

render方法只渲染视图，不调用另一个动作

Answer 4

The bigger issue here is that you are trying to call another action, which breaks MVC pattern. Even though actions are defined as methods, think of them as something else, that cannot call other actions.

Also, please reply with code from your views that are calling/trigger these actions.
