您好我尝试bundle exec rake db:migrate时遇到问题
我从来没有遇到过这个问题，这就是代码
bundle exec rake db:migraterake aborted!

Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)
这是我做rails generate controller AccountActivations \ edit --no-test-framework
然后routes.rb
Rails.application.routes.draw do
get 'account_activations/ edit'
get 'account_activation/ edit'
get 'sessions/new'
root 'static_pages#home'
get 'help' => 'static_pages#help'
get 'about' => 'static_pages#about'
get 'contact' => 'static_pages#contact'
get 'signup' => 'users#new'
get 'login' => 'sessions#new'
post 'login' => 'sessions#create'
delete 'logout' => 'sessions#destroy'
resources :users
resources :account_activations, only: [:edit]
end
然后我运行这段代码：
$ rails generate migration add_activation_to_users \
> activation_digest:string activated:boolean activated_at:datetime
我修改这个新文件
class AddActivationToUsers < ActiveRecord::Migration
def change
add_column :users, :activation_digest, :string
add_column :users, :activated, :boolean, default: false
add_column :users, :activated_at, :datetime
end end
最后bundle exec rake db:migrate
然后我收到错误消息，有没有人看到任何问题？提前致谢！
顺便说一下，这是第10章ruby on rails教程。
答案 0 :(得分：1)
help和about路线缺少它的控制器（可选动作）参数。
root路线也缺少它的选项。

您的routes.rb错了。
Rails.application.routes.draw do
get 'account_activations/edit'
get 'account_activation/edit'
get 'sessions/new'
root :to => 'static_pages#home'
get 'help' => 'static_pages#help'
get 'about' => 'static_pages#about'
get 'contact' => 'static_pages#contact'
get 'signup' => 'users#new'
get 'login' => 'sessions#new'
post 'login' => 'sessions#create'
delete 'logout' => 'sessions#destroy'
resources :users
resources :account_activations, only: [:edit]
end
答案 2 :(得分：0)
可能只是删除这两行将解决它：
get 'account_activations/ edit'
get 'account_activation/ edit'
您已在此处和资源中定义了此路线两次。
答案 3 :(得分：0)
我认为您可能正在使用
resources :account_activations
错误...应该在模型上使用资源，在这种情况下，它是一个控制器 - ＆gt;这是你的日志抱怨的。 以下是您的一些参考：http://guides.rubyonrails.org/routing.html#resources-on-the-web
资源路由允许您快速声明给定资源控制器的所有常用路由。而不是为索引，显示，新建，编辑，创建，更新和销毁操作声明单独的路由，而是一条资源丰富的路由在一行代码中声明它们。
也许跑一个
rake routes
查看您有哪些路线，以及“资源：account_activations”是否正在制作修改路线。
