how to send success message if we use django generic views

Question

I am new to django (1.2.4). I have created some crud with generic views. But How can I show something like "The student was added successfully" when student is created using django's messaging framework?

As of Django 1.6+, using any class-based generic views, you can rely on the successMessageMixin. It's as simple as adding the mixin to your class definition and setting success_message attribute to whatever you want.

As Olivier Verdier mentioned, please remember to display messages in your main template!

a simple example from the docs:

from django.contrib.messages.views import SuccessMessageMixin
from django.views.generic.edit import CreateView
from myapp.models import Author

class AuthorCreate(SuccessMessageMixin, CreateView):
    model = Author
    success_url = '/success/'
    success_message = "%(name)s was created successfully"

a more complex example:

from django.contrib.messages.views import SuccessMessageMixin
from django.views.generic.edit import CreateView
from myapp.models import ComplicatedModel

class ComplicatedCreate(SuccessMessageMixin, CreateView):
    model = ComplicatedModel
    success_url = '/success/'
    success_message = "%(calculated_field)s was created successfully"

    def get_success_message(self, cleaned_data):
        #  cleaned_data is the cleaned data from the form which is used for string formatting
        return self.success_message % dict(cleaned_data,
                                           calculated_field=self.object.calculated_field)
