Description
I have an array of simple scalar values and I want validation to fail when there is a duplicate.
This works, however I want to be able to see all duplicates at once and not resolve them one at a time.
So I added the allErrors option into the solution and I still only see a single error.
Code to reproduce:
var Ajv = require('ajv')
var ajv = new Ajv({ allErrors: true, uniqueItems: true });
var schema = {
"type": "array",
"items": [
{ "type": "number" }
],
"uniqueItems": true
}
var data = [1, 1, 2, 3, 3];
var validate = ajv.compile(schema);
console.log(validate.errors);
Result:
[ { keyword: 'uniqueItems',
dataPath: '',
schemaPath: '#/uniqueItems',
params: { i: 4, j: 3 },
message:
'should NOT have duplicate items (items ## 3 and 4 are identical)' } ]
From the docs: allErrors: check all rules collecting all errors. Default is to return after the first error.
