Django Postgres ArrayField(models.IntegerField) 迁移错误

Question

I am new to Django and my aim is to store a list of integers in Django model using ArrayField but when I run migrations it gives the following error

django.db.utils.ProgrammingError: column "object_ids" is of type integer[] but default expression is of type integer
HINT:  You will need to rewrite or cast the expression.

The field that i am using is:

ids=ArrayField(models.IntegerField(null=True, blank=True), null=True, blank=True)

Any help would be appreciated

Answer 1

You can try this

from django.db import models
from django.contrib.postgres.fields import ArrayField
# Create your models here.
class YourModel(models.Model):
    ids = ArrayField(models.IntegerField(),null=True, blank=True)
