What steps to create a class diagram of a project done with Django? How can I represent MVC in the diagram? My project has only one Post class:
from django.db import models
from django.utils import timezone
class Post(models.Model):
author = models.ForeignKey('auth.User')
title = models.CharField(max_length = 250)
content = models.TextField()
published_date = models.DateTimeField(blank = True, null = True)
def publish(self):
self.published_date = timezone.now()
self.save()
def __str__(self):
return self.title
I also created the following views:
from django.shortcuts import render
from django.utils import timezone
from .models import Post
from django.shortcuts import render, get_object_or_404
from .forms import PostForm
from django.shortcuts import redirect
def post_list(request):
posts = Post.objects.filter(published_date__lte = timezone.now()).order_by('published_date').reverse()
return render(request, 'blog/post_list.html', {'posts': posts})
def post_detail(request, pk):
post = get_object_or_404(Post, pk=pk)
return render (request, 'blog/post_detail.html', {'post': post})
def post_new(request):
if request.method == "POST":
form = PostForm(request.POST)
if form.is_valid():
post = form.save(commit=False)
post.author = request.user
post.published_date = timezone.now()
post.save()
return redirect('blog.views.post_list')
else:
form = PostForm()
return render(request, 'blog/post_create.html', {'form': form})
def post_edit(request, pk):
post = get_object_or_404(Post, pk=pk)
if request.method == "POST":
form = PostForm(request.POST, instance=post)
if form.is_valid():
post = form.save(commit=False)
post.author = request.user
post.save()
return redirect('blog.views.post_detail', pk=post.pk)
else:
form = PostForm(instance=post)
return render(request, 'blog/post_edit.html', {'form': form})
def post_delete(request, pk):
post = get_object_or_404(Post, pk=pk)
post.delete()
return render(request, 'blog/post_delete.html')
In trying to build a diagram I did just this:
