Enforce request body match validation schema

@fedeci

How to make sure the schema of the body is exactly of this form.

{
    'name': ...
    'description': ...
}

I mean if the body contains other fields than these (name, description), then I want to signal them by raising an exception.

Ex:

{
    'name': 'Bob'
    'description': 'Card player'
    'age' : 54
}

In this case, the validation should fail because the field age is not part of the wanted schema.

Obviously, it’s possible to create a custom task, but it would be a great asset to have this functionality in express-validator. Some kind of matchSchema(true)?

@erakis That’s integrated! You can chain that validation with all the others… As per deep validation, as I said, you just do some refactor using recursion… Here in Italy we say “Non esiste la pappa pronta”, which means you can’t find exactly what you need nice and ready to use 😃 Cheers

It would, just be sure to open and develop it against the v7-features branch!
