title: Pulling 'id' from sqlite3 into fieldset?
body: <p>I'm using django and python to create a web app. I have my sqlite3 DB and on the admin class I have:</p>
  
  <pre><code>class Job_Admin(admin.ModelAdmin):
      fieldsets = [
          (None,               {'fields': ['project', 'customer', 'pub_date', 'closed', ('contract','abamount')]}),
          ('Sales', {'fields': ['sales', 'office_choice'], 'classes': ['wide']}),
      ]
      list_display = ('project', 'id', 'sales', 'pub_date')
      search_fields = ['id', 'project']
  
  
  admin.site.register(New_job, Job_Admin)
  </code></pre>
  
  <p>Now the 'id' is the incremented number the sqlite db gives it. Im also using this as the 'job' number since I need it to increment as well. My issue is that I can use 'id' in the list_display and it works. But I can't put it into the fieldset, it errors out saying "'Job_Admin.fieldsets[0][1]['fields']' refers to field 'id' that is missing from the form."</p>
  
  <p>Extra: I am curious if I can give it a label/variable name because I will most likely need to pull this data out later too. </p>
