Question

我在处理draper gem时遇到了一些问题。

安装draper 宝石＆＃39; draper＆＃39;
```
$ bundle install
```

这是成功的。

做了rails generate draper:install
```
$ rails generate draper:install
```

但是我遇到了一些错误

    Expected string default value for '--test-framework'; got false (boolean)
    Expected string default value for '--helper'; got true (boolean)
    Expected string default value for '--assets'; got true (boolean)
    Expected string default value for '--test-framework'; got false (boolean)
    Expected string default value for '--helper'; got true (boolean)
    Expected string default value for '--decorator'; got true (boolean)
    Expected string default value for '--decorator'; got true (boolean)
    Expected string default value for '--jbuilder'; got true (boolean)
    Could not find generator draper:install.

没关系，我做了rails generate decorator Service

Expected string default value for '--test-framework'; got false (boolean)
Expected string default value for '--helper'; got true (boolean)
Expected string default value for '--assets'; got true (boolean)
Expected string default value for '--test-framework'; got false (boolean)
Expected string default value for '--helper'; got true (boolean)
Expected string default value for '--decorator'; got true (boolean)
Expected string default value for '--decorator'; got true (boolean)
Expected string default value for '--jbuilder'; got true (boolean)
Expected string default value for '--test-framework'; got false (boolean)
      create  app/decorators/service_decorator.rb

这是成功的。

在services_decorator中制作方法

class ServiceDecorator < Draper::Decorator
  delegate_all

  def hello
    'hello'
  end
end

从视图
调用此方法
```
<%= Service.first.decorate.hello %>
```

但这是错误，

    Could not infer a decorator for ActiveRecord::Base.

有人可以教我什么是错的以及如何解决这个问题？ rails版本为4.1.7，draper版本为2.1.0

要在使用rails生成器时删除错误，请将<fieldset> <legend>Reliable</legend> <div>More text here</div> <div>More text here</div> <div>More text here</div> <div>More text here</div> <div>More text here</div> <div>More text here</div> <div>More text here</div> <div>More text here</div> <div>More text here</div> </fieldset>版本更改为0.19.1

并尝试添加到gem thor application.rb

无法安装和使用＆＃34; draper＆＃34;宝石
