Rake aborted... table 'users' already exists
If you wanna play safe and don't want to lose any data then you can check if the table exists in your database.
class DeviseCreateUsers < ActiveRecord::Migration
def up
if table_exists?(:users)
# update or modify columns of users table here accordingly.
else
# create table and dump the schema here
end
end
def down
# same approach goes here but in the reverse logic
end
end
You need to drop that table from the sql lite console (You will lost all the data contained in it)
Access the sql lite console, type in terminal
mysql <DB NAME HERE>
Drop table (dont forget the last ; (semicolon))
drop table table_name;
run db:migrate again
bin/rake db:migrate
Hope it helps, it worked for me
The migration is trying to create a table that already exists in your database.
Try to remove the user table from your database. Something went wrong with you migration process. You should also compare your schema.rb version with your db/migrate/*.rb files.
Clarification:
It seems that many SO users don't agree with my reply, either because they consider it inaccurate or not recommended.
Removing a table is always destructive, and I think that everyone understands that.
I should have mentioned add_column, since the table was being created in another migration file.
In your create_users
migration (APP_ROOT/db/migrate/..), add drop_table :users
right before create_table :users
and run rake db:migrate
. It will remove the users table before recreating it. You can remove that line of code after running this migration so it doesn't give you errors later on. Just a small fix if you dont have UI access to a database (on heroku, for example).
