Using Django's 'get_absolute_url' (return the user to the same page after form submission)

Question

I am learning Django and have one question.

I have done a feedback form and I need to redirect the user to the same page after the feedback form confirmation. Below is the code:

models.py

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

urls.py

url(r'^feedback$',views.FeedbackSendForm.as_view(), name='feedback'),

views.py

class FeedbackSendForm(CreateView):
      model = Feedback
      fields = [
           'title',
           'text',
           'user_name',
           'user_lastname',
           'email',
           ]
      template_name = 'feedback.html'

feedback.html

<form method="post">
    {% csrf_token %}
    {% for field in form %}
        <span class="text-danger">{{ field.errors }}</span>
        <div>
            <label class="control-label">{{ field.label }}</label>
            {{ field }}
        </div>
    {% endfor %}
    <button type="submit">Submit</button>
</form>

How can I fix this?

Answer 1

If you want to override the get_absolute_url for your model, the following code can help you:

from django.urls import reverse

class Feedback(models.Model):
    # The model fields

    def get_absolute_url(self):
        # reverse expects the view name
        return reverse('feedback')

The absolute URL for any Feedback object will be the view FeedbackSendForm. That is specified by passing the view name feedback to reverse.
