使用"current_user"；在Ruby on Rails中的模型中

问题描述

我正在使用Devise，它在助手中提供了"current_user"方法，以便可以在视图和控制器中使用.

I'm using Devise and it offers "current_user" method in helpers, so that I can use in views and controllers.

但是，现在我想访问模型中的"current_user"方法.这就是我现在在控制器中拥有的东西.

However now I'd like to access to the "current_user" method in the models. Here's what I have in controllers now.

def create
  set_email_address(params[:email_address])
  Comment.new(params[:content], set_email_address)
  # [snip]
end

private
def set_email_address(param_email)
  if current_user
    @email_address = current_user.email
  else
    @email_address = param_email
  end
end

我想将"set_email_address"移动到模型中，因为我认为这是一种逻辑，应该将其交给模型.我打算将这种方法与Rails回调之一联系起来.

I would like to move the "set_email_address" to a model because I think that is a logic and should be handed in the model. I'm planning on hooking up this method with one of the Rails callbacks.

推荐答案

老实说，几乎总结了一下.这根本不属于模型逻辑.正如另一个答案还说的那样，如果您想在模型中使用它，则可以并且应该从控制器传递current_user值.

In all honesty, this answer pretty much sums it up. This doesn't belong in Model logic at all. As the other answer also says though, you can and should pass the current_user value from the controller if you'd like to use it inside your model.
