title: Django admin site adding "city object" instead of "City"
body: <p>I'm trying to create a basic weather forecast site on Django and this error arises. I successfully made a &quot;Cities&quot; section but when adding any city name, &quot;City Object 1&quot; is added. This then creates errors when reading JSON from the API key.</p>
  <pre><code>from django.db import models
  
  class City(models.Model):
      name = models.CharField(max_length=25)
  
      def _str_(self): #show the actual city name on the dashboard
          return self.name
  
      class Meta: #show the plural of city as cities instead of citys
          verbose_name_plural = 'cities'
  </code></pre>
  <p>admin.py</p>
  <pre><code>from django.contrib import admin
  from .models import City
  
  admin.site.register(City)
  </code></pre>
