rake：db迁移不在Refinery CMS应用程序中发生

Question

在http://refinerycms.com/guides/getting-started#rails-application-templates和

处进行使用Refinery CMS的教程

6使用您的第一个引擎扩展炼油厂

表示要运行

rails generate refinery:engine singular_model_name attribute:type [attribute:type ...]

然后运行

rails generate refinery:engine event title:string date:datetime photo:image blurb:text

之后我完成了剩下的工作，但rake db:migrate似乎无法正常工作，因为当我尝试运行rake db:seed时，我遇到了运行rake db:migrate所需的错误。我尝试在本地运行应用程序并获得此

这是在某个地方的终端，看起来很相关

ActionView::Template::Error (Could not find table 'refinery_events'):
1: <%= render 'refinery/admin/search_header', :url => refinery.events_admin_events_path %>
2: <div class='pagination_container'>
3:   <% if @events.any? %>
4:     <%= render 'events' %>
5:   <% else %>
6:     <p>

我也有关于作者的错误，但教程没有提到它

Using refinerycms-events (1.0) from source at vendor/extensions
refinerycms-events at /Users/juan.gallardo/Desktop/myfiles/test-projects/rickrockstar/vendor/extensions/events did not have a valid gemspec.
This prevents bundler from installing bins or native extensions, but that may not affect its functionality.
The validation message from Rubygems was:
  authors may not be empty

Using refinerycms-singular_model_names (1.0) from source at vendor/extensions
refinerycms-singular_model_names at /Users/juan.gallardo/Desktop/myfiles/test-projects/rickrockstar/vendor/extensions/singular_model_names did not have a valid gemspec.
This prevents bundler from installing bins or native extensions, but that may not affect its functionality.
The validation message from Rubygems was:
  authors may not be empty

所以我再次完成了这个过程

jgallardo:rickrockstar juan.gallardo$ rails generate refinery:events
    rake  refinery_events:install:migrations
  append  db/seeds.rb
jgallardo:rickrockstar juan.gallardo$ rake db:migrate
rake aborted!

这一次，我清楚地看到rake aborted，但无论如何都试过了

jgallardo:rickrockstar juan.gallardo$ rake db:seed
You have 2 pending migrations:
  20130826173639 CreateSingularModelNamesSingularModelNames
  20130826173941 CreateEventsEvents
Run `rake db:migrate` to update your database then try again.

我在Google上搜索了有待迁移的内容，我看到有人告诉其他有类似问题的人与--trace一起运行，所以这是我的尝试

jgallardo:rickrockstar juan.gallardo$ rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config

Answer 1

如果您阅读并思考他们所说的内容而不仅仅是复制＆amp;将部分内容粘贴到终端中。

在这种情况下，您复制和粘贴的示例是：

rails generate refinery:engine singular_model_name attribute:type [attribute:type ...] 

但是，在生成事件扩展名时，您已成功将此替换为正确的语法，因此没有问题。

删除名为CreateSingularModelNamesSingularModelNames的迁移及其整个相应的扩展名。您复制粘贴的示例语法，该语法不会产生有效的Ruby。

Answer 2

正如在接受的答案中指出的那样，我复制粘贴了错误的代码，如下面6.2所示

我最终只是删除了项目并重新开始。但后来我从下面粘贴了

一切都运转良好。
