Why is Sequelize Missing My Foreign Key Column in Model Associations?

Sequelize Model Association Foreign Key Column Creation Discrepancy

When defining model associations in Sequelize, it can be puzzling to encounter scenarios where foreign key columns are not consistently created in all models. In this situation, the user has observed that the role_id foreign key is missing from the User model table.

To resolve this issue, it is important to ensure that all models and their associations are registered in a centralized location. This can be achieved by following these steps:

1. Create a central database module (e.g., database.js) where models are imported as shown in the provided code snippet. This ensures that all models and their associations are loaded and registered with Sequelize.
2. In the main application logic, include the database module to access the models.

By implementing these steps, the foreign key column will be consistently created for all models, resolving the discrepancy encountered in the User model.
