get_absolute_url function not working?

[mp3909]

I change my code to incorporate crispy_forms.
Anyways, this is what my final code looks like so far:

models.py:

from django.db import models
from django.urls import reverse

# Create your models here.
class Album(models.Model):
	artist = models.CharField(max_length=250)
	album_name = models.CharField(max_length=500)
	genre = models.CharField(max_length=100)
	album_logo = models.ImageField()

	def get_absolute_url(self):
		return reverse('music:detail', kwargs={'pk':self.pk})

	def __str__(self):
		return self.album_name + " - " + self.artist

class Song(models.Model):
	album = models.ForeignKey(Album, on_delete=models.CASCADE)
	file_type = models.CharField(max_length=100)
	song_title = models.CharField(max_length=250)
	is_favourite = models.BooleanField(default=False)

	def __str__(self):
		return self.song_title

views.py:

from django.views import generic
from .models import Album, Song


# Create your views here.
class IndexView(generic.ListView):
	template_name = 'music/index.html'
	queryset = Album.objects.all()
	context_object_name = 'all_albums'


class DetailView(generic.DetailView):
	model = Album
	template_name = 'music/detail.html'


class AlbumCreate(generic.CreateView):
	model = Album
	fields = ['artist', 'album_name', 'genre', 'album_logo']

	def form_valid(self, form):
		return super().form_valid(form)

album_form.html:

{% extends 'music/base.html' %}
{% load crispy_forms_tags %}

{% block title %}Add a New Album{% endblock %}
{% block body %}
	<form method="post">
		{% csrf_token %}
		{{ form|crispy }}
		<input type="submit" value="Add">
	</form>
{% endblock %}

The issue I am having now is that when I fill in the form and upload a .jpg image in the album_logo field,
after clicking the Add button, it gives me an error saying no file was uploaded for the album_logo field, this field is required. I don't know why it is complaining as this is not true, I did upload an image from my desktop into this field.
This is the form:
