is_user

Test if a resource is a user.

A resource is a user when it has at least one identity of a user-defining type. These types are configured with auth_identity_types; by default this includes username_pw.

The filter accepts a resource id, unique name, or other value accepted by m_rsc:rid/2. It returns true when the resource exists and is a user, otherwise it returns false.

If the resource is not visible to the current user, it will return false, even if the resource is a user.

For example:

{% if id|is_user %}
    This resource can log on.
{% endif %}

Note that a user does not have to be a person. Any resource can have identities attached to it.
