对于我的数据模型,我有两种不同的类型:家人和 friend 。我的计划是让每个人都有一个指向由 Devise 创建的 User 表的外键。因此,当用户注册时,我希望他们转到/friends/sign_up 或 family_members/sign_up 。所以,我的 friend 类是
class Friend < ActiveRecord::Base
belongs_to :label
belongs_to :user
belongs_to :gender
belongs_to :location
belongs_to :orientation
belongs_to :matchmaker
def after_initialize
self.build_user if self.user.nil?
end
#accepts_nested_attributes_for :user
delegate :username, :to => :user
delegate :email, :to => :user
delegate :password, :to => :user
delegate :password_confirmation, :to => :user
delegate :rememebr_me, :to => :user
# Include default devise modules. Others available are:
# :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :username, :email, :password, :password_confirmation, :remember_me
end
我的用户类是
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
# devise :database_authenticatable, :registerable,
# :recoverable, :rememberable, :trackable, :validatable
attr_accessor :username, :email, :password, :password_confirmation, :remember_me
# Setup accessible (or protected) attributes for your model
attr_accessible :username, :email, :password, :password_confirmation, :remember_me
end
我也在使用 Formtastic 作为我的观点。
现在,我得到
unknown attribute: username
带参数
{"utf8"=>"✓", "authenticity_token"=>"8ScsJebuCWnflaRQkp9MsBuaaqfzQKaZBXotLyNwNyM=",
"friend"=>{"username"=>"aaaa",
"email"=>"aaa@aaa.com",
"password"=>"[FILTERED]",
"password_confirmation"=>"[FILTERED]"},
"commit"=>"Create Friend"}
现在,我只是随机尝试向两个模型添加 nested_attributes 和任何内容。我可以使用表继承,但我不想这样做(除非我可以向指向父类(super class)的子类添加外键,否则就可以了)。
最佳答案
好的,我已经解决了我满意的问题。这是我的新代码以供将来引用:
class Friend < ActiveRecord::Base
belongs_to :friend_user, :class_name =>
end
class FriendUser < User
set_table_name :users
has_one :friend
end
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :username, :email, :password, :password_confirmation, :remember_me
end
