title: Get all fields except one
body: <p>I am currently displaying my fields in the django admin interface via <code>model._meta.get_all_field_names()</code>. Now this works fine, but it also displays the Primary key  of the dataset (which doesn't look very nice in my opinion). </p>
  
  <p>So my question is: Is there a "lazy" way to get all fields except for one/multiple? Or do I have to write every single field except for the one(s) I don't want to have displayed into a <code>list_display = array_of_fields_to_be_displayed</code></p>
