Devise + omniauth + carrierwave doesn't save facebook profile image

问题

I am using devise with omniauth facebook. I upload avatars for people that are not signing in with facebook with carrierwave, with the AvatarUploader.

But when I try fetching the avatar from the facebook user, it does not save - user.avatar = auth.info.image does not save, and after signing in equals nil.

Why is that and how can I fix it? Thanks in advance.

  def self.from_omniauth(auth)
    where(auth.slice(:provider, :uid)).first_or_create do |user|
      user.provider = auth.provider
      user.uid = auth.uid
      user.email = auth.info.email
      user.avatar = auth.info.image
    end
  end

Have you tried this?

In your method, change the line

user.avatar = auth.info.image

to

user.remote_avatar_url = auth.info.image
