- used with: standalone
- any other relevant information: Not expected behavior
What are you trying to achieve or the steps to reproduce ?
I'm expecting an error when using { stripUnknown: true }
'use strict';
const Joi = require('joi');
const schema = Joi.object().keys({
emails: Joi.array()
.items(
Joi.object().keys({
value: Joi.string().email()
})
)
});
const data = {
emails: [{
value: 'hagrid@ potterworld'
}, {
value: 'hagrid@harrypotterworld.com'
}]
};
const resultDefault = Joi.validate(data, schema);
console.log(require('util').inspect(resultDefault, { depth: 3 }));
const resultStripUnknown = Joi.validate(data, schema, { stripUnknown: true });
console.log(require('util').inspect(resultStripUnknown, { depth: 3 }));Which result you had ?
[resultDefault] { error:
{ [ValidationError: child "emails" fails because ["emails" at position 0 fails because [child "value" fails because ["value" must be a valid email]]]]
isJoi: true,
name: 'ValidationError',
details:
[ { message: '"value" must be a valid email',
path: 'emails.0.value',
type: 'string.email',
context: [Object] } ],
_object: { emails: [ [Object], [Object] ] },
annotate: [Function] },
value:
{ emails:
[ { value: 'hagrid@ potterworld' },
{ value: 'hagrid@harrypotterworld.com' } ] } }
[resultStripUnknown] { error: null,
value: { emails: [ { value: 'hagrid@harrypotterworld.com' } ] } }What did you expect ?
I expect both results to be an error. Considering I'm specifically testing the value inside an array I was expecting the behavior to be an error, instead the value was removed. It may very well be intentional, I was just confused by the behavior.
