几乎就是我标题中所说的。我正在使用充当可投票的宝石，并且从我的终端，代码正在记录投票，并将其存储在投票表中。当我选择赞成按钮时，它会在尝试总结帖子中评论的赞成票时出现未定义get_vote的错误。
我正在尝试设置它，以便人们可以对帖子的评论投赞成票或反对票。
我的路线
Rails.application.routes.draw do
devise_for :users
# For details on the DSL available within this file, see

resources :comments
member do
put "like", to: "comments#upvote"

用户模型

注释模型
class Comment < ApplicationRecord
validates :user_id, presence: true
belongs_to :user
belongs_to :post
acts_as_votable

我的评论控制器
class CommentsController < ApplicationController
before_action :upvote
def create
@post = Post.find(params[:post_id])
@comment = @post.comments.new(comment_params)
@comment.user = current_user
if @comment.save
redirect_to @post
else
redirect_to @post
end
end
def destroy
@post = Post.find(params[:id])
@comment = @post.comments.find(params[:id])
@comment.destroy
redirect_to @post
end
def upvote
@post = Post.find(params[:id])
@comment = @post.comments.find(params[:id])
@comment.upvote_from current_user
redirect_to @post
end
def downvote
@post = Post.find(params[:id])
@comment = @post.comments.find(params[:id])
@comment.downvote_from current_user
redirect_to @post
end
private
def comment_params
params.require(:comment).permit(:text, :user_id, :username)
end
end

这是我遇到的错误
NoMethodError at/posts/1 # 的未定义方法 'get_upvotes'
屏幕截图以及错误
看起来您已将Comment设置为acts_as_votable，但您正在Post实例上调用get_upvotes。您是否包括acts_as_votablePost？
(另外，您发布的错误消息似乎遗漏了一些有关接收get_upvotes的详细信息(
