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?

Are you getting an error when running this? If yes, could post the Traceback? — Adam Jaamour, Sep 13 '17 at 10:48

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.

Example Createview:

views.py:

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

    def form_valid(self, form):
        """
        If the form is valid, redirect to the supplied URL.
        """
        return HttpResponseRedirect(self.get_success_url())
        """
        define `get_success_url' to your model or use `get_absolute_url` instead.

More information: class CreateView

If we define get_absolute_url in the model class then, while posting the form, we can leave the action tag as empty like this:

<form action="" method="post">

In this case, it now searches for the get_absolute_url in our model class defined as below:

def get_absolute_url(self):
    return reverse("post_detail", kwargs={"pk": self.pk})

After updating or adding data in the model, our page is redirected to the URL named as post_detail.
