Elasticsearch: Find all documents that have invalid entries in an array

We had a problem where invalid data got stored in elasticsearch. An array of objects had some objects placed in it that are missing a mandatory field. After fixing the mistake, we wanted to update all offending entires. For this, we need to get the IDs of affected items.

The "obvious" query would be _exists_:general_information AND !(_exists_:general_information.value). But as soon as there is any array element with a value, the second condition will consider the value existing. If there are any valid entries in the array, the query will not work as expected.

The solution we found was to use an ES script that loops over the elements in the source document and returns 1 if it finds one that has no data. To our positive surprise, running this on an index with over 1M entries only took a couple of seconds. Definitely not something for a routine query, but an acceptable time for a one-off query to fix a problem.

Symfony2: Role Hierarchy check independent of firewall

We needed to decide whether a user loaded from FOSUserBundle is granted a specific role. Because of the role hierarchy, this is not as simple as doing in_array($role, $user->getRoles()). The user model only knows about its roles, not about what other roles those roles grant it.

The only thing that handles this situation that i found is the SecurityContext::isGranted method. But the problem of that is that its a check about the role of the "current" user. We needed this information in a command that generates a file and needs to know which user has permission for a specific role.

The RoleHierarchy service can not do decisions but only explode roles into all roles granted through the tree. The RoleHiararchyVoter is part of the security manager. Both are private service and thus not intended to be reused in application code.

The simplest we could come up with is this code, which we use like this:

$roleHierarchy = $this->getContainer()->get('');
You can’t perform that action at this time.
