我正在编写一本书,教授自己Ruby-on-Rails。 页: 1
我开始使用废 rub/con,进入:
user = User.new(:screen_name => "example",
?> :email => "exampleATexample.com",
?> :password => "example")
但我没有将数据添加到非行,而是获得以下信息:
NameError: undefined local variable or method within for User:Class from D:/ruby/lib/gems/1.8/gems/activerecord-1.15.3/lib/active_record/base.rb:1235:in method_missing from ./script/../config/../config/../app/modules/user.rb:13
我并不真正理解正在发生什么。 非常感谢任何帮助,感谢你!
首先,我认为,你的主要铁路公司诉1.2.3号铁路公司,这是一个非常老的铁路,没有使用。
第二,你所进入的指挥机关错了Ruby syntax......而是试图这样做:
user =User.new(:screen_name => "example", :email => "exampleATexample.com", :password => "example")
第三点: 请颁布更多的法典......。
此外,正如检查一样。
无论在铁路做什么,只要与数据库做些什么,确保你经营。
rake db:migrate
有时,这可能lip倒你们的心灵,造成错误。
而且,正如一个方面指出的那样...... 我将确保你在用户模式中添加一些验证,要求用户确认其密码和电子邮件。 它一般是一种良好做法。
validates_confirmation_of :password, :email
最好的是学习铁路。 • 确保你接受@dvyjones的建议,并将之提升到最新铁路版本......自第1.2.3号案以来,已经发生了许多变化。
