我的 user.rb 看起来像这样:
class User < ActiveRecord::Base
attr_accessible :password, :password_confirmation, :crypted_password, :username, :password_salt, :persistence_token
acts_as_authentic
has_many :assignments
has_many :roles, :through => :assignments
def role_symbols
roles.map do |role|
role.name.underscore.to_sym
end
end
end
但是我在rails控制台中得到了这个:
x = User.create(:username => "foo", :password => "bar", :password_confirmation => "bar")
(0.2ms) BEGIN
User Exists (0.4ms) SELECT 1 AS one FROM "users" WHERE LOWER("users"."username") = LOWER('foo') LIMIT 1
User Exists (0.6ms) SELECT 1 AS one FROM "users" WHERE "users"."persistence_token" = 'e3c363da87d37fc7f17d3d1f4d4c851b93cf974ae614ec0b0cb9eb1935dd2dc2ccab34d0a06b4580881dc38e5b65027cce0f2e53a005860fc81d7f5e4c245d6a' LIMIT 1
(0.3ms) ROLLBACK
