Changing id column to string "breaks" schema.rb

Reported by Martin Vielsmaier | March 3rd, 2009 @ 08:21 AM | in 3.x

When you change the datatype of your id column with a migration like

change_column :users, :id, :string

your schema.rb will not contain this column:

...
create_table "users", :force => true do |t|
  t.string   "email"
  t.string   "pwd_hash"
  t.boolean  "is_active"
  t.datetime "last_activity"
  t.string   "pwd_salt"
  t.string   "activation_key"
  t.datetime "signup_date"
end

So you will end up with

rake db:migrate

and

rake db:schema:load

creating different schemas.

Same behavior when your create a table with

create_table :objects, :id => false do |t|
  t.string :id
end

1. I'm running into this problem right now. I use schema.rb to create the test db but I end up having to modify it before I do so. Fortunately it doesn't happen that much but it should never have to happen.

+1, we're reusing the id space of an external service as our own PK's and it goes beyond 2 ** 31 - 1

This issue has been automatically marked as stale because it has not been commented on for at least three months.

The resources of the Rails core team are limited, and so we are asking for your help. If you can still reproduce this error on the 3-0-stable branch or on master, please reply with all of the information you have about it and add "[state:open]" to your comment. This will reopen the ticket for review. Likewise, if you feel that this is a very important feature for Rails to include, please reply with your explanation so we can consider it.

Thank you for all your contributions, and we hope you will understand this step to focus our efforts where they are most helpful.
