django - 在 Django 数据库中存储整数数组

Question

在 Django 数据库中存储整数数组的最佳方法是什么？

Answer 1

CommaSeparatedIntergerField自 Django 1.9 起不再可用:

From Docs :

Deprecated since version 1.9: This field is deprecated in favor of CharField with validators=[validate_comma_separated_integer_list].

默认情况下，它设置一个逗号分隔的整数列表字段。

int_list_validator

Returns a RegexValidator instance that ensures a string consists of integers separated by sep. It allows negative integers when allow_negative is True.

from django.db import models
from django.core.validators import int_list_validator


class YourModel(models.Model):
    ....
    ....
    int_list = models.CharField(validators=int_list_validator)   
    ....
