我用Rails 3.0.3，并有数据为我的类别表已经在数据库中，但想要从中创建一个种子文件。是否有任何rake任务，将产生seeds.rb格式我从这个表？

I'm using Rails 3.0.3 and have data for my "categories" table already in the database, but want to create a seed file from it. Is there any rake task that will generate the seeds.rb format for me from this table?

推荐答案

不知道任何现有的rake任务，但你可以尝试运行这样的事情在轨控制台和放大器;结果粘贴到您的seeds.rb文件

Not sure about any existing rake tasks, but you can try running something like this in the rails console & paste the results into your seeds.rb file

（警告：脏放大器;未经测试）

(warning: dirty & untested)

c = Category.all

c.each do |cat|
  puts "Category.create(:name => '#{cat.name}')"
end

调整为任何其他领域，你可能有。

Adjust for any additional fields you may have.

希望这有助于。
