Solution for deleting by "name"

Question

I need solution for deleting Profesor by his 'name':

class Profesor(models.Model):
    user = models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE)
    name = models.CharField(max_length=200, null=True)
    suername = models.CharField(max_length=200, null=True)

Imagine is to ask user on html page to input 'name' of Profesor that he want to delete And then in views.py to delete Profesor by that 'ime' How can i do that?

I try to create form where i get 'name':

class getName(forms.Form):
    name = forms.IntegerField()

And then i views.py:

def obrisiProfesora(request):
    form = getName()
    if request.method=="POST":
        form = getName(requst.POST)
        form.save()
        context = {'form':form}
    profesor = Profesor.objects.filter(name=form.name)

    return render(request, 'brisanje_profesora.html', context)

But i dont know how to contionue this

Answer 1

• Class names are idiomatically PascalCase in Python, so getName would be GetName. However, NameForm might be more apt, since that's what it is, a form for a name.
• Similarly, functions are idiomatically snake_case.
• Why would the name field be an integer field, when the name field in the model is a CharField?
• form.save() isn't a thing for forms that aren't modelforms. That being said, I don't think you've tried that code very hard, since it'd crash at requst not being a thing, nor context having been defined.

All in all, with a plain function view you might want something like

class NameForm(forms.Form):
    name = forms.CharField(required=True)


def delete_professor(request):
    form = NameForm(data=(request.POST if request.method == "POST" else None))
    if form.is_bound and form.is_valid():
        professor = Profesor.objects.get(name=form.cleaned_data["name"])
        professor.delete()   
    return render(request, 'brisanje_profesora.html', context)

or with a class-based view (so you don't need to do so much work yourself),

class DeleteProfessorView(FormView):
    form_class = NameForm
    template_name = 'brisanje_profesora.html'

    def form_valid(self, form):
        professor = Profesor.objects.get(name=form.cleaned_data["name"])
        professor.delete()

Some error handling is elided from both solutions.
