How do you remove a model from mongoose?
It appears that you'd have to overwrite some of the source code in order to be able to remove a model an add a new one since Mongoose makes sure that a model doesn't exist before it's willing to create a new one, which may or may not be more than you care to do:
if (this.models[name] && !collection) {
// model exists but we are not subclassing with custom collection
if (schema instanceof Schema && schema != this.models[name].schema) {
throw new MongooseError.OverwriteModelError(name);
}
return this.models[name];
}

Question Author's Update:
Thanks to this answer I discovered that you can access the models defined on the connection through connection.models
. In my scenario I was testing a mongoose plugin with Mocha and and I wanted to clear the models between each unit test.
afterEach(function () {
mongoose.connection.models = {};
});
try this
delete mongoose.connection.models['Book'];
and then re-register/re-initialize it . it will work fine
