Migrations were shown as down but already migrated?

Question

I've rails app that has some migrations. When I hit rake db:migrate:status to see what status is set, all except ********** NO FILE ********** were down. But the migrations have already made, so there seems no problem about model side. Here are files may help to explain:

Output of rake db:migrate:status:

 up     20130727003912  ********** NO FILE **********
down    20130728000151  Devise create users
down    20130728000335  Create friends
down    20130728000346  Create addresses
down    20130728000356  Create authies
down    20130728000413  Add indexes

At this time, rake db:migrate output:

==  DeviseCreateUsers: migrating ==============================================
-- create_table(:users)
NOTICE:  CREATE TABLE will create implicit sequence "users_id_seq1" for serial column "users.id"

An error has occurred, this and all later migrations canceled:

How can I fix this issue to make all migrations seem up?

Answer 1

Your users tables is already created in your database but your schema migration is not updated with latest migration. I dont no why it has not been updated. You need to fix it then you can do it in two ways 1. drop the database and create one more or 2. run the down migration then up migration

rake db:drop
rake db:create
rake db:migrate

Answer 2

You can set force to true:

create_table :users, force: true do
   ...
end

in your migration and delete the migration key in your "schema_migrations" table by hand and rerun the migration.

Answer 3

this worked perfectly for me:

rails db:drop
rails db:create
rails db:migrate

You will notice that the file developmen.sqlite3 was removed and created again and now everything will be up and running rails db:migrate:status
