Re: unique_together does not work in django 2.0

[James Bennett]

You've indented the 'Meta' declaration too much, and Python thinks it's
part of the '__str__()' method of your class.

Un-indent it one level.

Hello, Problem solved. 
For it to work I have to put the META class between the silo class and the 
method. Thank you

To be clear, you started with an empty database and the duplicate values 
exist after adding data?

unique_together does not work in django 2.0

[FernandoJMM]

Hello,
I have the following class:

==
class Silo(models.Model):
nave = models.ForeignKey(Nave, on_delete=models.CASCADE)
codSil = models.CharField(
'Código Silo', db_index=True, max_length=2, default='01')
notas = models.TextField(null=True, blank=True)

def __str__(self):
return "%s %s" % (self.nave, self.codSil)

class Meta:
order_with_respect_to = 'nave'
unique_together = ('nave', 'codSil')


But the option unique_together does not work because duplicate values 
​​exist in the SQLite database for nave and codSil.

To solve it, I have to create the index nave + codSil by hand in the SQLite 
database ???

Thank you
