在http://refinerycms.com/guides/getting-started#rails-application-templates上学习使用 Refinery CMS 的教程
6 使用您的第一个引擎扩展炼油厂
说要运行
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
之后我完成了其余的工作，但rake db:migrate似乎没有工作，因为当我尝试运行时，rake db:seed我得到了一个我需要运行的错误rake db:migrate。我尝试在本地运行应用程序并得到了这个
这是在某个终端的某个地方，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>
我也收到了这个关于作者的错误，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
所以我再次经历了这个过程
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!
这次我清楚地看到了，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 上搜索了未决迁移的含义，我看到有人告诉其他有类似问题的人要运行，--trace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
** Execute db:migrate
rake aborted!
