How to display the posts of the user (author)?

Question

Django

models.py

class Post(models.Model):
    author = models.ForeignKey('auth.User', on_delete=models.CASCADE)

views.py

def beats_by_user(request, author):
    beats = Post.objects.get(author=author)
    return render(request, 'blog/beat_list.html', {'beats': beats})

urls.py

url(r'^profile_view/(?P<author>\w+)/$', views.beats_by_user, name='beats')

What am I doing wrong?
Post.objects.filter(author='keal')
Outputs Invalid literal for int()
Although author_id outputs

Answer 1

Post.objects.filter(author__username='keal')
