在create.js.erb中渲染rails部分的正確語法

我的註釋已成功從我的表單remote: true保存到數據庫，並從我的搜索中保存，以便在不重新加載需要的整個頁面的情況下更新這些新註釋使用create.js.erb文件呈現部分註釋。這一切都以自舉模式進行。在create.js.erb中渲染rails部分的正確語法

create.js.erb

$(".instacomments").html("<%= escape_javascript(render partial: "comments/comment", collection: photo.comments, as: :comment) %>");

CommentsController

def create 
    @photo = Photo.find(params[:photo_id]) 
    @comment = @photo.comments.build(comment_params) 
    @comment.save 
    respond_to do |format| 
     format.html { redirect_to :back } 
     format.js 
    end 
end

<%= comment.content %>

您的文件名實際上是'create.js.erb'而不是'_create.js.erb'。請在問題中改變它以避免混淆。 – Pavan

::的ActionView模板::錯誤（未定義局部變量或方法 `照片」爲＃<＃：0x007fa5594987d8>）

您需要create.js.erb

$(".instacomments").html("<%= escape_javascript(render partial: "comments/comment", collection: @photo.comments, as: :comment) %>");

你可以改變photo到@photo用戶這種語法它會正常工作

$('.instacomments').html('<%= escape_javascript render(:partial=>"comments/comment",collection: @photo.comments, as: :comment, :format => [:html]) %>');

這沒有奏效。它需要是@photo而不是照片。謝謝。 –
