title: How to change the name of objects in Django admin?
body: <p>What to do? I kept restarting my server but it still didn't work. This is the whole code snippet of my models.py:</p>
  
  <pre><code>from django.db import models
  
      class Blog(models.Model):
          title = models.CharField(max_length=50)
          pub_date = models.DateField(auto_now_add=True)
          # publication date
          image = models.ImageField(upload_to='images/')
          summary = models.CharField(max_length=200)
          body = models.TextField()
  
      def __str__(self):
          return self.title
  </code></pre>
  
  <p>But the names of each objects are still not changing:
