How to verify the fields?

[nymlc]

I have a User model with age field and I want to verify the field is number
I can think of, just check resolveParams in wrapResolve

thanks

By default graphql checks that field has number type. But if you want to add some additional checks you may do it via wrapResolve.

How I understood you want to do it with mutation, so it can be done in such way:

graphql-compose-mongoose/src/__tests__/github-issues-test.js

Lines 109 to 113 in dad8908

	UserTC.wrapResolverResolve('createOne', next => rp => {
	if (rp.args.record.age < 21) throw new Error('You are too young');
	if (rp.args.record.age > 60) throw new Error('You are too old');
	return next(rp);
	});
