Answer 1

I don’t know if you put the wrong code in the question, but the indentation is wrong, the right one would be:

class Midia(models.Model):

    analista = models.CharField(max_length=50)
    denuncia = models.CharField(max_length=50)
    linkDenuncia = models.CharField(max_length=500)
    ticketAxur = models.CharField(max_length=50)
    numeroFacebook = models.IntegerField(null=True)

    class Meta:
        ordering = ["-analista", "-denuncia"]

    def __str__(self): 
        return self.analista

    def get_absolute_url(self):
        return reverse("midia:update", kwargs={"id": self.id})

If you can, enter the error that appears in Terminal, the error line, etc.
