我在 Twitter 身份验证方面遇到了一点麻烦。我不断收到电子邮件不能为空,并重定向到注册,但插入电子邮件并单击注册后,我仍然收到相同的错误。我试着让它变得不需要,但我得到一个错误,说已经存在带有“”电子邮件的人。谢谢。
设计路线.rb
def has_role?(role)
return true;
end
def self.from_omniauth(auth)
where(auth.slice(:provider, :uid)).first_or_create do |user|
user.provider = auth.provider
user.uid = auth.uid
user.username = auth.info.nickname
end
end
def self.new_with_session(params, session)
if session["devise.user_attributes"]
new(session["devise.user_attributes"]) do |user|
user.attributes = params
user.valid?
end
else
super
end
end
def password_required?
super && provider.blank?
end
def update_with_password(params, *options)
if encrypted_password.blank?
update_attributes(params, *options)
else
super
end
end
end
Call Back Controller
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
def all
user = User.from_omniauth(request.env["omniauth.auth"])
if user.persisted?
flash.notice = "Signed in!"
sign_in_and_redirect user
else
session["devise.user_attributes"] = user.attributes
redirect_to new_user_registration_url
end
end
alias_method :twitter, :all
end
