title: Add button not showing up in Django tutorial 02
body: <p>I am new to Django and have been going through the official tutorial on www.djangoproject.com. I have successfully implemented the tutorial 1 in my system but I am unable to figure out why the <strong>"plus" or "add" button is not showing up</strong> in the admin panel.</p>
  
  <p>I am using <strong>django 1.6.1</strong> 
  It is a pretty simple code but I am unable to figure it out since I don't have any prior knowledge of Django. Help will be appreciated.</p>
  
  <p>Below is the code for the files models.py and admin.py</p>
  
  <p>models.py</p>
  
  <pre><code>from django.db import models
  
  class Poll(models.Model):
      question = models.CharField(max_length=200)
      pub_date = models.DateTimeField('date published')
      def __unicode__(self):  # Python 3: def __str__(self):
          return self.question
  
  class Choice(models.Model):
      poll = models.ForeignKey(Poll)
      choice_text = models.CharField(max_length=200)
      votes = models.IntegerField(default=0)
      def __unicode__(self):  # Python 3: def __str__(self):
           return self.choice_text
  </code></pre>
  
  <p>admin.py</p>
  
  <pre><code>from django.contrib import admin
  from polls.models import Choice, Poll
  
  """class ChoiceInline(admin.TabularInline):
      model = Choice
  
  class PollAdmin(admin.ModelAdmin):
      fieldsets = [
          (None,               {'fields': ['question']}),
          ('Date information', {'fields': ['pub_date'], 'classes': ['collapse']}),
      ]
      list_display = ('question', 'pub_date')
      inlines = [ChoiceInline]
      list_filter = ['pub_date']
      search_fields = ['question']
  """
  admin.site.register(Choice)
  </code></pre>
