from django.db import models

# Create your models here.
class Song(models.Model):
    title = models.CharField(max_length=255)
    artist = models.CharField(max_length=255)
    performer = models.CharField(max_length=255)
    duration = models.DurationField()

    def __str__(self):
        return '{} by {}'.format(self.title, self.artist)

In your models:

  • performer should be a foreign key in the Song class, as it refers to an object of the Performer class
  • no need to turn the name into a string with str() in Performer.__str__(). It's already a string.

In the views:

  • you need to get the data from the db
  • pass in the data to the render() methods

In the template:

  • you need to show the songs by each performer

@ursaminor Thank you for your answer, unfortunately, I found that in the tests there are several syntax errors, I saw this because I write the code in my local, so I could find this. The problem is when I copy and paste the code inside the test I've got the same general error so I really don't understand what's the error. :/
