javascript - How do you remove a model from mongoose?

Question

I don't mean remove a document or documents. I mean remove the model entirely so that mongoose is no longer aware of it. After declaring a model I can't figure out how to make mongoose forget that model so that it could be recreated.

mongoose.model('Book', bookSchema);
mongoose.model('Book', bookSchema);

Currently the above throws an exception.

OverwriteModelError: Cannot overwrite 'Book' model once compiled.

I'd like to be able do something like this...

mongoose.model('Book', bookSchema);
mongoose.removeModel('Book');
mongoose.model('Book', bookSchema);

...and not get any errors. Any ideas?

Answer 1

try this

delete mongoose.connection.models['Book'];

and then re-register/re-initialize it . it will work fine
