I'm working with a project with docker-compose, where I have a postgre container.

When I run:

docker-compose -f dev.yml run django python manage.py migrate

I get the error:

django.db.utils.ProgrammingError: multiple default values specified for column "id" of table "scrapy_scrapy"

That is happening before I made some changes to my models.py file. But now the file is correct and should be working. This is the content of the models.py file:

from django.db import models
import django

# Create your models here.
class Scrapy(models.Model):
    user = models.CharField(max_length=50,blank=True)
    password = models.CharField(max_length=50,blank=True)
    projecte = models.CharField(max_length=100)
    estat_last_check = models.CharField(max_length=700, default="", blank=True)
    date = models.DateTimeField(default=django.utils.timezone.now, blank=True)

    app_label = ''
    def __str__(self):              # __unicode__ on Python 2
        return self.projecte + " - " + self.user

    class Meta:
        app_label = 'scrapy'

As you can see, no id filed is defined anymore, so, why is complaining about that field?

I've done my research and tried some possible solutions, but no luck. I've already tried deleting the full Docker container and creating it again, or trying to delete the database.

Any ideas?
