  24. Building Blocks of Django ORM ORM stands for Object-relational Mapper. Define your data models. You get a rich, dynamic database-access API for free but you can still write SQL if needed. URLs and Views Templates Forms from django.db import models Authentication Class employees(models.Model): firstname = models.CharField(max_length=10) Lastname = models.CharField(max_length=10) Admin def _str_(self): return self.firstname Internationalization Security Copyright © 2017, edureka and/or its affiliates.

  25. Building Blocks of Django ORM Like a table of contents for your app, it contains a simple mapping between URL patterns and your views. URLs and Views Templates from django.conf.urls import url Forms from . import views URL Authentication urlpatterns = [ url(r'^$', views.index, name='index'), ] Admin from Django.shortcuts import render def index(request): return HttpResponse (<h2> Hey!

URLs and Views Templates Forms Authentication Admin Internationalization Security Copyright © 2017, edureka and/or its affiliates. All rights reserved.

  28. Building Blocks of Django ORM It handles user accounts, groups, permissions and URLs and Views cookie-based user sessions. Templates Forms from django.contrib.auth.decorators import login_required from django.shortcuts import render Authentication @login_required def my_protected_view(request): return render(request, 'protected.html', {'current_user': request.user}) Admin Internationalization Security Copyright © 2017, edureka and/or its affiliates.
