Where to convert an error into a text message?

Question

Django

The model has a method that processes the sent data and returns an error if something happens.
Where is the best place in the framework to translate the error code into a message for the user?
View or template?

Answer 1

In view via messages

Answer 2

views.py

from django.contrib import messages

def feedback(request):
    form = FeedbackForm(request.POST or None)
    if form.is_valid():
        instance = form.save(commit=False)
        instance.save()
        messages.success(request, 'Ваше сообщение отправлено! Мы свяжемвся с Вами в скором времени!')
        return render(request, "feedback.html")
    context = {
        'form': form,
    }
    return render(request, 'feedback.html', context)

html

{% for message in messages %}
    <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li>
    {% endfor %}
