我在设计注册时收到此错误：

undefined method `users_url' for #<Devise::RegistrationsController:0x00000003b299b0>

使用 Omniauth facebook，登录，一切正常。

class User < ActiveRecord::Base
  has_one :profile, :dependent => :destroy

  after_save :myprofile

  def myprofile
    if self.profile
    else
      Profile.create(user_id: self.id, user_name: self.name)
    end
  end
end

class Profile < ActiveRecord::Base
  belongs_to :user
end

使用设计注册进行此工作的解决方案可能是什么？

重要提示：它适用于 omniauth facebook，但不适用于设计注册。

编辑：我在 Profile.create 中收到此错误！方法：

NoMethodError - undefined method `users_url' for #<Devise::RegistrationsController:0x00000005946e20>:

问题解决了：

在 profile.rb 中：

validates_uniqueness_of :slug

导致问题，因为对于 Profile.user_name 在 user.rb 中有以下内容：

after_save :myprofile

def myprofile
  Profile.create!(user_id: self.id, user_name: self.name)
end

通过向 User.name 添加唯一性验证来解决问题，然后将其作为唯一性传递给配置文件，然后创建一个唯一的 :slug。

用户.rb：

validates_uniqueness_of :name

The profile you're creating with Profile.create(user_id: self.id, user_name: self.name) isn't associated with any User. In order to build a has_one dependency, use the build_resource method on self in an after_create callback:

# app/models/user.rb
class User < ActiveRecord::Base
    has_one :profile, :dependent => :destroy

    after_create :myprofile

    def myprofile
        profile = Profile.create!(user_id: self.id, user_name: self.name) # `.create!` will throw an error if this fails, so it's good for debugging
        self.profile = profile
    end
end
