Heroku rails migration problem?

It could be that the error is happening on a different migration, as you're not including devise recoverable column, and your script doesn't reference the column *reset_password_token.

Class DeviseCreateUsers false t. Recoverable t. Rememberable t.

Timestamps end add_index :users, :email, :unique => true add_index :users, :reset_password_token, :unique => true end def self. Down drop_table :users end end Remember that when you use heroku you push your git repository, so if you have uncommitted changes (as you've mentioned), heroku won't see them.

Git commit -a -m "updated some files" Then git push heroku master.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
