コンソール内でmigrateする方法

コンソールでUserを作成しようとした際にエラーでできず、最終的にコンソール内でmigrateするのに時間がかかったので備忘録にする。

> User.create(name: "山田次郎")
=> ActiveRecord::StatementInvalid (PG::UndefinedTable: ERROR:  relation "users" does not exist)

> User
=> User(Table doesn't exist)

> rails db:migrate
=> NameError (undefined local variable or method `migrate' for main:Object)
> class CreateUsers < ActiveRecord::Migration[6.0]
>   def change
>     create_table :user do |t|
>       t.string :name

>       t.timestamps
>     end
>   end
> end

> ActiveRecord::Migration.run(CreateUsers)
-- create_table(:users)
   -> 0.0132s
=> [CreateUsers]

これでUser.createすることができた。
