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

I was also facing the same problem. The solution to my problem was looking at the ref parameter which had a different name compared to the model I was actually exporting and hence no such model was found.

userSchema.virtual('tasks', {
    ref: 'Task',
    localField: '_id',
    foreignField: 'owner'
})
  

Whereas what I had actually exported was :-

const Tasks = mongoose.model('Tasks', taskSchema)

module.exports = Tasks

After rectifying the Task as Tasks my problem was solved
