12. Reason #4 Models, Views, URLs, Templates
13. Blog - Models # models.py class Post(models.Model): title = models.CharField(max_length=200) author = models.ForeignKey( 'auth.User', on_delete=models.CASCADE, ) body = models.TextField()
14. Blog - Views # views.py from django.views.generic import DetailView from .models import Post class BlogDetailView(DetailView): model = Post template_name = 'post_detail.html'
15. Blog - URLs # urls.py from django.urls import path from .views import BlogDetailView urlpatterns = [ path('post/<int:pk>/', BlogDetailView.as_view(), name='post_detail'), ]
16. Blog - Template # post_detail.html {% extends 'base.html' %} {% block content %} <div class="post-entry"> <h2>{{ post.title }}</h2> <p>{{ post.author }}</p> <p>{{ post.body }}</p> </div>
17. Reason #5 Multiple Ways to Do the Same Thing
18. Example 1 - Templates App-level └── blog_project ├── posts ├── templates ├── pages ├── post_detail.html Project-level └── blog_project ├── posts ├── templates ├── post_detail.html
19. Example 2 - Settings files • Two Scoops advocated using local, dev, and production settings.py files • Environment variables the more modern approach but not well documented yet. • Most beginners are super confused by this!
20. Example 3 - About Page 3 ways # views.py from django.shortcuts import render def about_page_view(request): return render(request, 'about.html')
21. Example 3 - About Page 3 ways # views.py from django.views.generic import TemplateView class AboutPageView(TemplateView): template_name = 'about.html'
22. Example 3 - About Page 3 ways # urls.py from django.views.generic import TemplateView urlpatterns = [ path(‘about/', TemplateView.as_view(template_name=’about.html’), name='about'), ]
23. Reason #6 FBVs vs CBVs
24. Two Scoops of Django
25. FBVs > CBVs > GCBVs
26. Reason #7 User model
