title: Django get_absolute_url (Return user to the same page after form submission)
body: <p>Learning django. I have one question.
  I have done feedback form and I need to redirect the user to the same page after feedback form confirmation. Below is the code:</p>
  
  <p><strong>models.py</strong></p>
  
  <pre><code>class Feedback(models.Model):
        title = models.CharField(max_length=255)
        text = models.TextField(max_length=5000)
        user_name = models.CharField(max_length=255)
        user_lastname = models.CharField(max_length=255)
        email = models.EmailField(max_length=255)
        send_time = models.DateTimeField(auto_now_add=True)
        update_time = models.DateTimeField(auto_now=True)
  
        def get_absolute_url(self):
              return
  </code></pre>
  
  <p><strong>urls.py</strong></p>
  
  <pre><code>url(r'^feedback$',views.FeedbackSendForm.as_view(), name='feedback'),
  </code></pre>
  
  <p><strong>views.py</strong></p>
  
  <pre><code>class FeedbackSendForm(CreateView):
        model = Feedback
        fields = [
             'title',
             'text',
             'user_name',
             'user_lastname',
             'email',
             ]
        template_name = 'feedback.html'
  </code></pre>
  
  <p><strong>feedback.html</strong></p>
  
  <pre><code>&lt;form method="post"&gt;
      {% csrf_token %}
      {% for field in form %}
          &lt;span class="text-danger"&gt;{{ field.errors }}&lt;/span&gt;
          &lt;div&gt;
              &lt;label class="control-label"&gt;{{ field.label }}&lt;/label&gt;
              {{ field }}
          &lt;/div&gt;
      {% endfor %}
      &lt;button type="submit"&gt;Submit&lt;/button&gt;
  &lt;/form&gt;
  </code></pre>
