我不知道为什么会这样.一切都在本地很好,但不是在heroku上.我在研究之后尝试了各种不同的修复方法,但我可能不得不完全重命名这个类的CommentsController(希望这很有效).最好的方法是什么？我对Rails很新,所以我需要一些帮助才能正确地改变它们.

以下是CommentsController看起来像FYI的内容：

class CommentsController < ApplicationController
  def new
    @post = Post.new(params[:post])
  end

  def show
    @comment = Comment.find(params[:id])
    respond_to do |format|
      format.js
    end
  end

  def create
    @post = Post.find(params[:post_id])
    @comment = Comment.new(params[:comment])
    @comment.micropost = @post
    @comment.user = current_user
    if @comment.save
      redirect_to(:back)
    else
      render partial: 'shared/_comment_form',locals: { post: @post }
    end
  end
end

评论与每个帖子相关联(用户可以对帖子发表评论).如果需要,我也会发布其他代码.

这是heroku日志的错误

当我在rails app文件夹中运行高级索引搜索时,会出现相关文件
