Question

我有一个允许用户评论帖子的应用程序。

rails generate model Comment commenter:string body:text post:references

如何更改，以便将commenter设置为发布评论的用户

Answer 1

您需要建立关联：

rails generate model Comment author_id:integer body:text post:references

class Comment < ActiveRecord::Base

  belongs_to :post
  belongs_to :author, class_name: <User or whatever your user model is called>, foreign_key: :author_id

end

class User < ActiveRecord::Base
  has_many :comments, foreign_key: :author_id
end

创建新评论时，您还需要指定此值：

#Comment controller? Hard to say how it is being saved from the code you posted. :P

  def create
    @comment = Comment.new(params[:comment])
    @comment.user = current_user
    if @comment.save
      ...
    end
  end

Answer 2

我终于找到了解决问题的方法。

rails generate model Comment user_id:integer body:text listing:references

将:user_id添加到attr_accessible文件中的\app\models\comments.rb，然后将隐藏属性添加到评论表单中：

<%= f.hidden_field :user_id, :value => current_user.id %>

然后使用<%= comment.user.id %>和/或<%= comment.user.name %>

将评论与用户关联
