Django Error while trying to migrate model on Postgre DB


Django Error while trying to migrate model on Postgre DB



I'm still learning to use Django and I have an issue while trying to create a model.
Here's my models.py


class Identifiants(models.Model):
id = models.AutoField(primary_key=True)
taxon = models.IntegerField(unique=True)
noms = models.TextField(blank=True, null=True)
fiche = models.IntegerField(blank=True, null=True)
comestible = models.TextField(blank=True, null=True)
sms = models.NullBooleanField()
a_imprimer = models.NullBooleanField()
lieu = models.TextField(blank=True, null=True)
apparition = models.TextField()

class Meta:
managed = True
db_table = 'identifiants'



The makemigrations command works with no issues but the migrate one is where I have problems


Running migrations:
Applying app.0001_initial...Traceback (most recent call last):
File "/usr/lib/python3.5/site-packages/django/db/backends/utils.py", line 83,
in _execute
return self.cursor.execute(sql)
psycopg2.DataError: NUMERIC precision 65535 must be between 1 and 1000
LINE 1: ...iants" ("id" serial NOT NULL PRIMARY KEY, "taxon" numeric(65...



I'm using IntegerField method so I can't see why there is an issue ...



Can anyone help me ?



Thanks

Remove id = models.AutoField(primary_key=True) id is automatically created by django.


id = models.AutoField(primary_key=True)



check it here, its similar to your question.





Working ! Thanks a lot !
