Does sails.js support database views? - node.js

Question

I would like to migrate my application to sails.js. But, I use database views on my PostgreSQL database for some functions.
I try to make a model for this view. But, it causes an ORM error when I perform sails lift.
error: A hook (`orm`) failed to load!
error: error: relation "homeview" already exists

Does sails.js support database views, and if so do they require special configuration?

Answer 1

You can use a database view with your Sails app by setting the migrate property to safe in the model that uses the view:
module.exports = {
migrate: 'safe',
attributes: {
...
}
}
This will restrict Sails from performing migrations on the view, meaning that if you add new attributes to the model, they will not be automagically added to the database view. You'll have to keep your Sails model and your database view in sync manually.
