[Validator] Unique constraint can't be applied to collection of object #48072
Description
Description
In its current state, the option fields in the constraint Unique only works for a collection of array. In my case, I have an array of object and thus, it doesn't work on it.
Example
Improving the current constraint is simple : using a PropertyAccessor instead of using array access completely solve the problem without breaking current usage :
private function reduceElementKeys(array $fields, array $element): array
{
$output = [];
foreach ($fields as $field) {
if (!\is_string($field)) {
throw new UnexpectedTypeException($field, 'string');
}
// Using property accessor (injected in constructor?)
if ($this->propertyAccessor->isReadable($element, $field)) {
$output[$field] = $this->propertyAccessor->getValue($element, $field);
}
// Old (using array access)
/*if (isset($element[$field])) {
$output[$field] = $element[$field];
}*/
}
return $output;
}If the idea is validated, I'll do the request right after if needed
