Create, Update and Delete in Django - django

Question

I am only creating entries for some fields in my models.py at the moment. Now I want to add Delete and Update functions to my Application. Let's take this Model for example:
class todoList(models.Model):
trainee = models.ForeignKey(trainee, verbose_name = "Azubi", blank = True)
todoLearningObjective = models.ManyToManyField(learningObjective, verbose_name = "Lernziel", blank = True, null = True)
tasks = models.TextField(verbose_name = 'Aufgaben')
levyDate = models.DateField(verbose_name = 'Abgabedatum', blank = True, null = True)
priority = models.IntegerField(verbose_name = 'Prioritaet', blank = True, null = True)
class Meta:
verbose_name = "To-Do Liste"
verbose_name_plural = "To-Do Listen"
The matching Form:
class todoListForm(forms.Form):
formtrainee = forms.IntegerField(required = False)
formtodoLearningObjective = forms.CharField(required = False)
formtasks = forms.CharField(required = True)
formlevyDate = forms.DateField(required = False)
formpriority = forms.IntegerField(required = False)
And the View:
def todo(request):
trainee_objects = trainee.objects.all()
usernameID = 1
for traineeUser in trainee_objects:
if traineeUser.username == request.user.username:
usernameID = traineeUser.id
if request.method == 'POST':
forms = todoListForm(request.POST)
if forms.is_valid():
formtasks = forms.cleaned_data['formtasks']
formtodoLearningObjective = forms.cleaned_data['formtodoLearningObjective']
formlevyDate = forms.cleaned_data['formlevyDate']
formpriority = forms.cleaned_data['formpriority']
neueTodo=todoList(tasks=formtasks, levyDate=formlevyDate, priority=formpriority, trainee_id = usernameID)
neueTodo.save()
for todo in learningObjective.objects.filter(learningObjectives=formtodoLearningObjective):
neueTodo.todoLearningObjective.add(todo)
else:
forms = todoList()
return render(request, 'todo.html', {'todo': todoList.objects.all(), 'Lernziel': learningObjective.objects.all()})
As you can see, I have M to M relations and I am just creating new entries. My question is now: Do I have to create a new update and delete method for every model ? Or is there an easier way ? I want to keep my project DRY although I probably failed that mission already. It would be awesome if you could give me example or documentation on how Deleting and Updating in Django works all in all.

Answer 1

You have built class based views for that.
from django.views.generic import CreateView,UpdateView,DeleteView
class Todo(CreateView):
formClass = todoListForm
template_name = 'your_template_name.html'
