在我仅使用Omni auth + devise为用户注册之前。一切工作正常。后来我决定使用设计的简单注册形式。我配置了它,它也工作正常,但是当用户想要使用Omni认证注册时出现问题。即使Facebook/Github正在将链接返回到个人资料图片,但头像始终设置为零。我试过这solution但是,仍然不工作,我知道载波远程位置上传方法。我用于Omni auth的宝石是omniauth-facebook和omniauth-github。Devise + Omniauth + Carrierwave不保存facebook/github个人资料图片

User.rb
代码:
class User < ApplicationRecord
include Storext.model
devise :database_authenticatable, :registerable, :omniauthable,
:recoverable, :rememberable, :trackable, :validatable
validates :first_name, :last_name, :email, :experience_level,
:goal_level, :theoretical_learner_level, presence: true
mount_uploader :avatar, AvatarUploader
# Override devise method for Oauth
def self.new_with_session(params, session)
if session['devise.user_attributes']
new(session['devise.user_attributes'].merge(session[:user_attributes])) do |user|
user.attributes = params
user.valid?
end
else
super
end
end
def self.from_omniauth(auth)
where(auth.slice(:provider, :uid).to_hash).first_or_create do |user|
OauthUserGenerator.new(user: user, auth: auth).generate
end
end
# If sign in through Oauth, don't require password
def password_required?
super && provider.blank?
end
# Don't require update with password if Oauth
def update_with_password(params, *options)
if encrypted_password.blank?
update_attributes(params, *options)
else
super
end
end
end

oauth_user_generator.rb
代码:
class OauthUserGenerator
def initialize(user:, auth:)
@user = user
@auth = auth
end
def generate
@user.provider = @auth.provider
@user.uid = @auth.uid
@user.email = @auth.info.email
@user.password = Devise.friendly_token[0, 20]
@user.first_name = @auth.info.name.split[0]
@user.last_name = @auth.info.name.split[1]
@user.remote_avatar_url = @auth.info.image
end
end

omniauth_callbacks_controller.rb
代码:
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
def omniauth_providers
process_oauth(request.env['omniauth.auth'].merge(session.fetch(:user_attributes, {})))
end
alias facebook omniauth_providers
alias github omniauth_providers
private
def process_oauth(omniauth_params)
user = User.from_omniauth(omniauth_params)
if user.persisted?
flash.notice = 'Signed in!'
sign_in_and_redirect user
else
session['devise.user_attributes'] = user.attributes
redirect_to new_user_email_registration_path
end
end
end
谢谢。
