# Policy Lookup

Action Policy tries to automatically infer policy class from the target using the following _probes_:

1. If the target responds to `policy_class`, then use it;
2. If the target's class responds to `policy_class`, then use it;
3. If the target's class responds to `policy_name`, then use `#{target.class.policy_name}Policy`;
4. Otherwise, use `#{target.class.name}Policy`.

> \* [Namespaces](namespaces.md) could be also be considered when `namespace` option is set.

You can call `ActionPolicy.lookup(record, options)` to infer policy class for the record.

When no policy class is found, an `ActionPolicy::NotFound` error is raised.

You can [customize lookup](custom_lookup_chain.md) logic if necessary.
