I am creating a new migration like this:
rails g migration add_confirmable_to_devise
And it is generating the file in: db/migrate/YYYYMMDDxxx_add_confirmable_to_devise.rb
and I add this:
class AddConfirmableToDevise < ActiveRecord::Migration
# Note: You can't use change, as User.update_all will fail in the down migration
def up
add_column :users, :confirmation_token, :string
add_column :users, :confirmed_at, :datetime
add_column :users, :confirmation_sent_at, :datetime
# add_column :users, :unconfirmed_email, :string # Only if using reconfirmable
add_index :users, :confirmation_token, unique: true
# User.reset_column_information # Need for some types of updates, but not for update_all.
# To avoid a short time window between running the migration and updating all existing
# users as confirmed, do the following
User.update_all confirmed_at: DateTime.now
# All existing user accounts should be able to log in after this.
end
def down
remove_columns :users, :confirmation_token, :confirmed_at, :confirmation_sent_at
# remove_columns :users, :unconfirmed_email # Only if using reconfirmable
end
end
and then I do rake db:migrate
I get that Process finished with exit code 0
but when I try to test it to sign up I get: undefined local variable or method 'confirmed_at' for #User
I am following these instruction here
Is it because I have mongodb? Is it done differently in mongodb?
No
Taken from RailsApp GitHub Issue:
When you use Mongoid and MongoDB, there is no need to run rake
db:migrate
. An advantage of using MongoDB is there is no need for migrations or schemas.
From Mongo Doc:
Mongoid does not utilize ActiveRecord migrations, since MongoDB does not require a schema to be defined prior to storing data.
When using MongoDB, you only need to configure the fields on the model. Migrations (and Schemas) are used for SQL databases.
