How to compare sourceItem.userInfo and domainUserInfo in FileProvider extension ActivationRule?

I'm creating a Rename-forbidden NSFileProviderUserInteractions rule.

My goal: if sourceItem owner is not currently logged-in user, Rename should be forbidden.

User-interaction rule in Info.plist file:

<dict>
  <key>ActivationRule</key>
  <string>action == &quot;Rename&quot; AND sourceItem.userInfo.owner != domainUserInfo.user</string>
  <key>SubInteractions</key>
  <array>
    <dict>
      <key>ActivationRule</key>
      <string>TRUEPREDICATE</string>
      <key>Alert</key>
      <dict>
        <key>LocalizedRecoveryOptions</key>
        <dict>
          <key>Cancel</key>
          <string>OK</string>
        </dict>
        <key>LocalizedSubTitle</key>
        <string>Only owners can rename items.</string>
        <key>LocalizedTitle</key>
        <string>Forbidden action</string>
        <key>RecoveryOptions</key>
        <dict>
          <key>Continue</key>
          <false/>
        </dict>
      </dict>
    </dict>
  </array>
</dict>

It smells like comparing

sourceItem.userInfo.owner != domainUserInfo.user

doesn't seem to work.

I also see an error in console:

[ERROR] User interaction  is not a dictionary

If, on the other hand I hard-code the ActivationRule like:

<key>ActivationRule</key>
<string>action == &quot;Rename&quot; AND sourceItem.userInfo.owner != "current_user_id"</string>

then the behavior is correct (Rename is forbidden only for items not belonging to current user).

Is there a way to compare sourceItem.userInfo and domainUserInfo in ActivationRule predicate?

Solution

  • In the end the problem seemed to be elsewhere: I didn't properly set the collection owner in FileProviderEnumerator.enumerateItems() method. Once I fixed that, things started working smoothly.

    Closing as resolved.
