- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?

我是Rails的新手,并且正在为我的雇主构建一个简单的项目跟踪应用程序。我一直在Mac上开发该应用程序,并将其推送到github。我只是设法将github存储库克隆到公司防火墙后面的Windows盒中,希望让同事试用该应用程序。
但是,当我转到rake db:migrate在Windows框中初始化数据库时,出现以下错误消息:
$ rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!

最佳答案
在过去的几个星期中,我一直在进行的一个辅助项目中遇到了这个确切的问题。当我用rake db:migrate
运行--trace.
时,答案才对我很清楚。在那里,我注意到堆栈跟踪提示factory_girl无法实例化丢失的表项。
我进入了factory.rb文件并删除了有问题的模型,之后我就可以运行rake db:migrate
了。另外,对我来说,问题是:
Factory.define :table1 do |b|
b.name "table1"
b.rating 5
b.table2_relation Factory(:table2)
end
Factory.define :table1 do |b|
b.name "table1"
b.rating 5
b.table2_relation {Factory(:table2)}
end
