Adding message to Storage Views

In the last two videos, we learnt how to use message framework in function based view and class based view. In this video, we are going to learn how to use message framework in generics views.

Import

At first, open your views.py file of center. Since we are dealing with generic views, we need a mixin calles SuccessMessageMixin.

from django.contrib.messages.views import SuccessMessageMixin

We will utilize this mixin in the generic views in order to add support for message framework.

Create Storage View

In the create storage view, you have to inherit the SuccessMessageMixin.

class CreateStorage(SuccessMessageMixin, generic.CreateView):

You need to make sure that SuccessMessageMixin comes before generic.CreateView

Now, to add success mesage to this view, you need to add "success_message" in the class.

success_message = "Storage Created Successfully"

In this way, we can add a success message in the generic CreateView.

Storage Update View

Similary, in the storage update view, at first, we will inherit SuccessMessageMixin.

class StorageUpdate(SuccessMessageMixin, generic.UpdateView):

Now, we have to add success_message in this class.

success_message = "Storage Updated Successfully"

In this way, we can add a success message in the generic UpdateView.

Storage Delete View

At last, in the storage delete view, we will inherit SuccessMessageMixin.

class StorageDelete(SuccessMessageMixin, generic.DeleteView):

Now, we will add success_message in this class.

success_message = "Storage Deleted Successfully"
