PG :: UndefinedTable: ERROR: отношение "user_profiles" не существует при попытке запустить: heroku run rake db: migrate

Я создал веб-приложение в рельсах, и я использовал sqlite3. Сейчас я пытаюсь развернуть его с помощью heroku, который использует pg, но я сталкиваюсь с этой ошибкой: 

PG::UndefinedTable: ERROR:  relation "user_profiles" does not exist

Я немного осмотрелся, но все еще не могу заставить ее работать. Я вижу, что это связано с моими user_profiles. Модель моего профиля пользователя: 

class UserProfile < ApplicationRecord
    belongs_to :user, class_name: 'User', foreign_key: 'user_id'
    validates_uniqueness_of :user_id



end

Это миграция моего профиля пользователя: 

class CreateUserProfiles < ActiveRecord::Migration[6.0]
  def change
    create_table :user_profiles do |t|
      t.integer :user_id
      t.string :name
      t.integer :age
      t.string :address
      t.string :ptName
      t.string :bio

      t.timestamps
    end
    add_foreign_key :user_profiles, :users, column: :user_id
    add_index :user_profiles, :user_id, unique: true
  end
end

Ошибка возникает, когда я go для просмотра моего приложения через heroku я вижу это: Ошибка приложения. Вот я и пробую запустить: heroku запустить rake db: migrate и ошибка в названии происходит. Я думаю, это может быть связано с тем, что Pg более строг с внешними ключами. Есть предложения?

Из Rails 5 - когда мы ссылаемся на модель, автоматически создается индекс для foreign_key.

Просто сделайте это, как показано ниже - 

class CreateUserProfiles < ActiveRecord::Migration[6.0]
  def change
    create_table :user_profiles do |t|
      t.references :user, null: false, foreign_key: true
      t.string :name
      t.integer :age
      t.string :address
      t.string :ptName
      t.string :bio

      t.timestamps
    end
  end
end
