Hey @timothyarmes,
Sequelize handle createdAt and updatedAt by default, and so does FA. You can disable these column manually using something like
sequelize.define('user', { /* bla */ }, {
// don't add the timestamp attributes (updatedAt, createdAt)
timestamps: false,
// If don't want createdAt
createdAt: false,
// If don't want updatedAt
updatedAt: false,
// your other configuration here
});
(See node.js - disable updatedAt (update date) field in sequelize.js - Stack Overflow)
For your second question, I think Smart fields/Smart relationships is what you are looking for.
Let me know if that helps
