我正在尝试为我的应用程序构建身份验证系统
注册用户填写表格然后提交调用用户#signup
def signup
@user = User.new(params[:user])
@user.password(params[:user][:password])
@user.save
end`
我的用户模型包含
def password(pass)
@password=pass
self.salt = User.random_string(10)
self.hashed_password = User.encrypt(@password, self.salt)
end
尝试调试时,我检查了@user散列中包含的内容:
在@user = User.new(params[:user])
哈希包含我的参数exept'id','hashed_password'和'salt'(加上时间戳)之后
@user.password(params[:user][:password])
后,哈希值包含'hashed_password'和'salt'的值
@ user.save返回
UsersController#signup中的ArgumentError
错误的参数数量(0表示1)

有什么想法吗?
答案 0 :(得分:1)
我猜你有一个名为password
的列和/或你有一个引用:password
的验证。
在这种情况下,问题是你已经用password
(一个参数的设置器)覆盖了password(pass)
- 隐式零参数getter。您应该将您的setter移动到password=
,然后创建一个始终返回nil的getter:
def password
nil
end
def password=(pass)
@password = pass
self.salt = User.random_string(10)
self.hashed_password = User.encrypt(@password, self.salt)
end
作为奖励,这意味着您可以取消明确的密码设置调用,因为User.new(:password => 'xyz')
会自动调用password=
。
