Rake db：migrate - 如何知道是否存在非运行迁移

Question

I am working on an existing rails application, making changes and updating it.

How do I check if there are unrun rake db:migrate in it? Is there a direct command?

Answer 1

Running this:

rake db:migrate:status

Would give you this:

   up     20130415141113  Rename coupon to discount coupon
   up     20130416144722  Create ratings
  down    20130419102623  Add published to product
  down    20130419124429  Add attachment photo to users

Anything that is 'down' has NOT been migrated.

Answer 2

rake db:migrate:status

会给你这些信息
