使用非current_page时遇到问题?隐藏按钮

Question

我试图在Rooms模型的所有显示页面中隐藏此按钮。我在@extra中存储了一组房间id，但每当我尝试使用current_page?(room_path(@extra))时，它都不起作用，但当我指定id时，例如current_page?(room_path(6))，它起作用并隐藏按钮。我做错了什么？

<% unless current_page?(controller: 'rooms') || current_page?(room_path(@extra))%>
<button onclick="myFunction()" class="button btn btn-light bg-white rounded-pill shadow-sm px-4 mb-4" 
style="vertical-align:middle">
<span>
<small class="text-uppercase font-weight-bold"> Nav-bar Toggle</small>
</span>
</button>
<% end %>

Answer 1

基于注释中提供的信息。show路径需要一个id才能完成。你可以通过进行检查

current_page?(controller: 'rooms', action: 'show', id: room_id)

而不是

current_page?(controller: 'rooms', action: 'show')

---

如果您想对照特定的房间id进行检查，您可以使用

current_page?(controller: 'rooms', action: 'show', id: room_id)

如果您只想检查控制器和操作，而不考虑房间id，则必须使用另一种策略。你可以使用，

if params[:controller] == :rooms && params[:action] == :show

或与正则表达式匹配

if request.fullpath =~ //rooms/d+/
