Rails：試圖在點擊上呈現一個parial的邏輯有什麼問題？

Question

我試圖讓活動時，在用戶點擊按鈕叫display 控制器：

def display 
    @activities = Activity.all 
    @activities = Activity.order("created_at desc") 

    #we will need to find the Post id Through Users relation to the Comments 
    #And this is because Activity Track, tracks Users actions, it breaks down from there. 

    @posts = Post.all 
    @user_comments = UserComment.all  
    respond_to do |format|    
    format.js { @activities = Activity.order("created_at desc") } 
    end 

查看：

<%= link_to "Display", activities_path, :remote => true %> 
<div id="notify" class="section-link"> 
    </div> 

display.js.erb

$('#notify').append("<%= escape_javascript(render :partial => 'layouts/activity') %>"); 

_activity.html.erb

<% @activities.each do |activity| %> 
     <%= ActivityPresenter.new(activity, self).render_activity %> 
    <% end %> 

Answer 1

試試這個在display.js.erb：

$('#notify').append('<%= escape_javascript(render :partial => 'layouts/activity', :collection => @activities) %>');

然後，嘗試這_activity.html.erb：

<%= ActivityPresenter.new(activity, self).render_activity %>

爲了確保每當用戶點擊「顯示」display動作被調用，您需要調整您的routes.rb文件，它位於config目錄中。你可以這樣做在routes.rb中是這樣的：

get '/activities/display', 'activities#display', as: :activity_display

一旦你在routes.rb中這種變化，您可以編輯link_to這樣的：

<%= link_to "Display", activity_display_path, :remote => true %>
