body: <p>I'm getting an error:</p>
  
  <pre><code>AlreadyRegistered at / The model Post is already registered
  </code></pre>
  
  <p>Why is this happening, and how do I fix it? Here's my models.py :</p>
  
  <pre><code>from django.db import models from
  django.contrib import admin
  
  
  class Post(models.Model):
      title = models.CharField(max_length=60)
      body = models.TextField()
      created = models.DateTimeField(auto_now_add = True)
  
      def __unicode__(self):
          return self.title
  
  
  class PostAdmin(admin.ModelAdmin):
      search_fields = ["title"]
  
  admin.site.register(Post,PostAdmin)
  </code></pre>
