django models timefield o min:sec format

Question

How can I set TimeField format in django models to be [min:sec] like for an audio track?

class Song(models.Model):
    title = models.CharField(max_length=128)
    duration = models.TimeField(null=True)

Answer 1

Create form.py in app and inherit this form in view also if you want to use same concept in admin then also inherit in django admin

from django import forms
from .models import Song
class SongForm(forms.ModelForm):
    duration = forms.TimeField(widget=forms.TimeInput(format='%H:%M'))
    class Meta:
        model = Song
