jade tasks about express-example

Same issue here. I'm new to Node and Sequelize is the first ORM I'm choosing to test out but it's making it extremely difficult to get up and running with this error. (Using ExpressJS as well).

I just solved it!!!

1.In the file /models/users.js there's a line that starts with 'User.hasMany'. Change it so that it reads:
User.hasMany(models.Task, {as:'tasks'});
2.In the file /routes/index.js there's a line that starts with 'include'. Change it so that it reads:
include: [ {model: db.Task, as: 'tasks'} ]

Note: I'm using postgreSQL (the code is thought for mysql, however I'd bet this fact is not related with this issue)

The actual problem was that the code used user.tasks whereas it has to be user.Tasks. Though I wonder if that has always been the case.
