美好的一天。也许我的问题是无稽之谈，但我在推特错误中单挑后：
Devise中的ArgumentError :: RegistrationsController #new
错误的参数数量（给定2，预期为0..1）
我在我的应用程序和其他工作中使用multiply singup
我的回调控制器：
class User < ApplicationRecord
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable,
:omniauthable, omniauth_providers: %i[google_oauth2 twitter github]
def self.from_omniauth(auth, _signed_in_resource = nil)
user = User.where(provider: auth.provider, uid: auth.uid).first
if user.present?
user
else
user_with_email = User.find_by_email(auth.info.email)
if user_with_email.present?
user = user_with_email
else
user = User.new
if auth.provider == 'github'
user.provider = auth['provider']
user.uid = auth['uid']
user.oauth_user_name = auth['info']['name']
user.email = auth['info']['email']
user.save
elsif auth.provider == 'twitter'
user.provider = auth.provider
user.uid = auth.uid
user.oauth_token = auth.credentials.token
user.oauth_expires_at = auth.extra.raw_info.name
elsif auth.provider == 'google_oauth2'
user.provider = auth.provider
user.uid = auth.uid
user.oauth_token = auth.credentials.token
user.first_name = auth.info.first_name
user.last_name = auth.info.last_name
user.email = auth.info.email
user.oauth_expires_at = Time.at(auth.credentials.expires_at)
user.save
end
end
end
user
end
def self.new_with_session(params, session)
if session['devise.user_attributes']
new(session['devise.user_attributes'], without_protection: true) do |user|
user.attributes = params
user.valid?
end
else
super
end
end
def password_required?
super && provider.blank?
end
end
感谢您的关注和帮助。
