Question

我目前正在获得投票以访问数据库，但我现在遇到了让更新操作在我的控制器中工作的问题。投票不会记录更新操作，但不会将其记录下来。但是，我为Pits＃update丢失了模板错误。任何帮助表示赞赏。感谢。

终端错误

我目前有

坑控制器

class PitsController＆lt; ApplicationController中

def new
  @pit = Pit.new
end

def index
  @pit = Pit.all
  @user = User.find_by(params[:id])
  @pits = Pit.paginate(:page => params[:page]).order('created_at ASC').group_by { |pit| pit.created_at.strftime("%B %Y") }
end




def create
  @user = current_user
  @pit = current_user.pits.create(pit_params)
    if @pit.save
      redirect_to @pit
    else
      render 'new'
    end
end



def show
  @pit = Pit.find(params[:id])
end

def edit
end

def update
   @user = current_user
   @pit = current_user.pits.find(params[:id])
   if @pit.update_attributes(pit_params)
      redirect_to @pit
end
end

private

def pit_params
    params.require(:pit).permit(:topic, :summary, :image, :video_url, :author, :user_id)
end

end

评论控制器

class CommentsController < ApplicationController


 def create
  @pit= Pit.find(params[:pit_id])
  @comment = @pit.comments.build(comments_params)
  @comment.user = current_user
  @comment.save

  redirect_to pit_path(@pit)
end

  def destroy
    @pit = Pit.find(params[:pit_id])
    @comment = @pit.comments.find(params[:id])
    @comment.destroy
    redirect_to pit_path(@pit)
end

def upvote
  @pit = Pit.find(params[:pit_id])
  @comment = @pit.comments.find(params[:comment_id])
  @comment.upvote_by current_user
  redirect_to pit_path(@pit)
end

def downvote
  @pit = Pit.find(params[:pit_id])
  @comment = @pit.comments.find(params[:comment_id])

def update
end




def show  
end

def comments_params
    params.require(:comment).permit(:body, :user_id, :votable, :voter, :vote_scope)

不确定您在此处所做的一切，但我怀疑该错误与使用current_user查找pit有关。如果current_user不是坑的user_id，它将找不到任何坑（确切地说是你的错误）。

尝试调整到这个，它应该能够正确地找到坑。

def update
   @pit = Pit.find(pit_params[:id])
   if @pit.update_attributes(pit_params)
      redirect_to @pit
end

使用acts_as_votable进行更新操作的问题
