CommentsController#create 中的 NoMethodError 和 LikesController#create 中的 NoMethodError

Question

我遇到了点赞和评论的未定义方法错误。你能帮忙吗？我的仓库分支是 https://github.com/sja-thedude/Blog-App/tree/Add-Forms

likes_controller.rb

class LikesController < ApplicationController
  def create
    @post = Post.find(params[:post_id])
    new_like = current_user.likes.new(
      user_id: current_user.id,
      post_id: @post.id
    )
    new_like.update_likes_counter
    if new_like.save
      redirect_to "/users/#{@post.user_id}/posts/#{@post.id}", notice: 'Success!'
    else
      render :new, alert: 'Error occured!'
    end
  end
end

comments_controller.rb

class CommentsController < ApplicationController
  def create
    @post = Post.find(params[:post_id])
    new_comment = current_user.comments.new(
      text: comment_params,
      user_id: current_user.id,
      post_id: @post.id
    )
    new_comment.update_comments_counter
    if new_comment.save
      redirect_to "/users/#{@post.user_id}/posts/#{@post.id}", notice: 'Success!'
    else
      render :new, alert: 'Error occured!'
    end
  end

  private

  def comment_params
    params.require(:comment).permit(:text)[:text]
  end
end

它说

app/controllers/likes_controller.rb:4:in create' 中出现错误并且app/controllers/comments_controller.rb:4:in创建'

来自 ApplicationController 的 current_user 方法实际上返回用户列表（尽管技术上仅包含 1 条记录）。

将 User.limit(1) 替换为 User.take 或 User.first 之类的内容。
