title: NgIF with 3 or clauses and null objects
body: <p>it looks like I do not know how to create an NgIf with 3 Or clauses together, but I can not find what is wrong or any example to copy from:</p>
  
  <pre><code>*ngIf="owner === photo.calbum.community.user.id || owner === photo.album.user.id || isAdmin == true"
  </code></pre>
  
  <p>Then I have a JSON object that in some records but sometimes it has a photo from an Album (or it is null), or sometimes it has a common album that belong to a community (or it is null because the photo belong to an Album). </p>
  
  <p>In both cases they all belong to a user, but through different objects. But one of them will be null always and I need to check the whole JSON file.</p>
  
  <p>Thanks.</p>
