Mongoose Schema hasn't been registered for model

Question

I\'m learning the mean stack and when I try to start the server using

npm start

I get an exception saying that:

schema has         


        

Answer 1

If someone coudn't fix it with the approach of the correct answer (like me), try to look at the creation of the schema. I wrote the 'ref' as 'User', but the correct was 'user'.

Wrong:

createdBy: {
    type: Schema.Types.ObjectId,
    ref: 'User'
}

Correct:

createdBy: {
    type: Schema.Types.ObjectId,
    ref: 'user'
}
