我正在尝试设置 Devise像这样:
$ rails generate devise:install
...
$ rails generate devise User
...
$ rake db:migrate --stack
rake db:migrate --stack 行导致此错误:

Tasks: TOP => db:migrate => environment
user.rb 看起来像这样:
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable, :lockable and :timeoutable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me
end
如果我注释掉 devise :database_authenticatable... 行，然后运行 rake db:migrate --stack，我会收到此错误:

User does not respond to 'devise' method. This usually means you haven't loaded your ORM file or it's being loaded too late. To fix it, be sure to require 'devise/orm/YOUR_ORM' inside 'config/initializers/devise.rb' or before your application definition in 'config/application.rb'

是什么导致了这些错误？
我正在运行 Rails 3.0.1 和 Ruby 1.9.2
最佳答案
您使用的是 ruby 1.8.7 和 rake 0.9~？
试试这个:
module ::YOUR_APP_NAME
class Application
include Rake::DSL
end
end
关于ruby-on-rails - 是什么导致了这些 Devise 错误？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7129490/
