渲染部分不顯示

我有軌應用程序，用戶可以like a post，當用戶點擊「喜歡」鏈接時，「喜歡」鏈接將更改爲「不喜歡」鏈接（使用渲染部分），也可以創建一個記錄like，它的工作保存到數據庫，我可以看到部分已在日誌中呈現，但部分未在視圖上顯示也刪除了「喜歡」鏈接。渲染部分不顯示

你渲染它作爲'create_like.js'的集合，但你只有一個對象。我不確定這是唯一的問題，但它可能是其中的一部分。 –

@Baloo謝謝baloo，我已經改變了集合到本地對象看起來像這樣'$（'＃like _ <％= dom_id（@post）％>'）。empty（）。append（'<％= j render：partial = >「homes/like_dislike」，：locals => {：post => @post}％>'）;'並且它的工作原理 – itx

您說：「當我嘗試重新加載/刷新頁面時，顯示不喜歡鏈接。這是否意味着部分**被顯示，但是您看到的是「不喜歡」鏈接而不是來自部分的「喜歡」鏈接？ –

Baloo說：「您將它作爲create_like.js中的集合呈現，但您只有一個對象。」所以，我想改變這種

$('#like_<%= dom_id(@post) %>').empty().append('<%= j render :partial => "homes/like_dislike", :collection => @post, :as => :post %>');

到

$('#like_<%= dom_id(@post) %>').empty().append('<%= j render :partial => "homes/like_dislike", :locals => {:post => @post } %>');
