Django — Views

Function-Based Views

# blog/views.py
from django.http import HttpResponse
from django.shortcuts import render, get_object_or_404

def home(request):
    return HttpResponse("Hello, World!")

def post_list(request):
    return render(request, 'blog/list.html', {'posts': posts})

def post_detail(request, pk):
    post = get_object_or_404(Post, pk=pk)
    return render(request, 'blog/detail.html', {'post': post})

Class-Based Views

from django.views.generic import ListView, DetailView
from .models import Post

class PostListView(ListView):
    model = Post
    template_name = 'blog/list.html'
    context_object_name = 'posts'

class PostDetailView(DetailView):
    model = Post
    template_name = 'blog/detail.html'
    context_object_name = 'post'

Request Object

def my_view(request):
    request.method      # 'GET' or 'POST'
    request.GET         # Query parameters
    request.POST        # Form data
    request.FILES       # Uploaded files
    request.user        # Current user
    request.session     # Session data

HttpResponse

from django.http import HttpResponse, JsonResponse, HttpResponseRedirect

def my_view(request):
    return HttpResponse("Hello")
    return JsonResponse({'key': 'value'})
    return HttpResponseRedirect('/success/')

Mini Practice

1. Create function-based views
2. Create class-based views
3. Access request data
4. Return different response types
