title: Ignore a particular field (column) in Realm Android
body: <p>I have referred <a href="https://github.com/realm/realm-java/issues/2288" rel="nofollow">this</a> applied some work around but didn't find the solution for ignoring a particular field during <code>realm.copyToRealmOrUpdate(...)</code> unless and until modified externally.
  Any solution or idea will be appreciated</p>
  
  <p>using below dependency</p>
  
  <pre><code>compile 'io.realm:realm-android:0.87.2'
      //compile 'com.github.realm:realm-android:v1.0.0'
  compile 'com.github.realm:realm-android-adapters:v1.0.0'
  </code></pre>
