Rails - 使用设备以访客身份撰写评论。设计主张？

发布于 2024-12-09 11:41:28 字数 1134 浏览 0 评论 0原文

我希望能够以访客或注册用户的身份使用设备撰写评论。

我的评论模型包含 :title、:content、:user_id、:guest_email、:guest_website< /strong> 和 :write_as_guest 作为布尔值。

我想仅在没有用户登录时验证 :guest_email 是否存在。但我认为我并没有朝着好的方向发展。

我正在使用 AJAX/jQuery 管理表单，我想要一个访客表单，其中 :content 和 :guest_email 是必需字段。另一方面，我希望用户表单中只需要 :content 。

以下是我尝试的方法。

class Comment < ActiveRecord::Base
  before_validation :set_write_as_guest

  belongs_to :user

  validates_presence_of :content
  validates_presence_of :guest_email, :if => :write_as_guest?

  private

  def write_as_guest?
    self.write_as_guest
  end

  def set_write_as_guest
    if user_signed_in?
      self.write_as_guest = false
    else
      self.write_as_guest = true
    end
  end

end

好像是user_signed_in？方法需要 before_filter :authenticate_user!然后我的 comments_controller 中有以下内容

before_filter :authenticate_user!, :only => :create

但是我不想验证创建，因为那是访客...

所以如果有人能够向我提出一种以访客或用户身份编写的方法，那就是真的很感激。

谢谢

I want to be able to write a comment as a guest or as a registered user with devise.

My comment model contains :title, :content, :user_id, :guest_email, :guest_website and :write_as_guest as a boolean.

I wanted to validate the presence of :guest_email only when no user is signed_in. But I think I'm not going in the good direction.

I'm managing the form with AJAX/jQuery and I wanted to have a guest form where :content and :guest_email are necessary fields. In another hand, I want to have the user form where only the :content is necessary.

Here is how I tried to go for it.

class Comment < ActiveRecord::Base
  before_validation :set_write_as_guest

  belongs_to :user

  validates_presence_of :content
  validates_presence_of :guest_email, :if => :write_as_guest?

  private

  def write_as_guest?
    self.write_as_guest
  end

  def set_write_as_guest
    if user_signed_in?
      self.write_as_guest = false
    else
      self.write_as_guest = true
    end
  end

end

It seems that user_signed_in? method needs before_filter :authenticate_user! then I have the following in my comments_controller

before_filter :authenticate_user!, :only => :create

But however I don't want to authenticate to create because that's a guest...

So if somebody would be able to propose me a way to write as a guest or as a user, that would be really appreciated.

Thx

您可以像这样进行自定义验证

class Comment < ActiveRecord::Base
  validate :guest_commentator

    def guest_commentator
      user = User.find(user_id)
      self.errors.add(:user_id => "some error message here ") unless user.nil? 
    end
  end

You can do a custom validation like this

class Comment < ActiveRecord::Base
  validate :guest_commentator

    def guest_commentator
      user = User.find(user_id)
      self.errors.add(:user_id => "some error message here ") unless user.nil? 
    end
  end
