title: Django - updating application after adding rows to database?
body: <p>I have a <code>Django</code> web application which is synced to a <code>PostgreSQL</code> database.
  After adding some rows to a couple of tables (using <code>pgAdmin</code>, not the <code>Django</code> application itself) i started experiencing some problems with the application.
  For example, i would get the following error in some tables:</p>
  
  <blockquote>
    <p>Duplicate key value violates unique constraint "some_key_pkey" DETAIL:
    Key (id)=736284 already exists.</p>
  </blockquote>
  
  <p>My assumption is that i had to let the <code>Django</code> application know somehow that i have added new rows to the database.</p>
  
  <p>Could that really be the case? If so, how can i solve it?</p>
