我刚刚将我的应用程序从Rails 2.3升级到3,并且我为before_create,update,save,destroy等获得了一些DEPRECATION WARNINGS.
有谁知道怎么解决这个问题？
这些是我的警告:
DEPRECATION WARNING: Base#before_create has been deprecated, please use Base.before_create :method instead. (called from /Users/macmini/qna/app/models/user.rb:32)
DEPRECATION WARNING: Base#before_update has been deprecated, please use Base.before_update :method instead. (called from /Users/macmini/qna/app/models/user.rb:40)
DEPRECATION WARNING: Base#after_save has been deprecated, please use Base.after_save :method instead. (called from /Users/macmini/qna/app/models/user.rb:50)
DEPRECATION WARNING: Base#before_destroy has been deprecated, please use Base.before_destroy :method instead. (called from /Users/macmini/qna/app/models/user.rb:56)
只是一个before_create的例子:
def before_create
self.username.downcase!
self.salt = User.make_salt(self.username)
self.hashed_password = User.hash_with_salt(@password, self.salt)
end
