将json保存为django的postgres db中的数组

from django.contrib.postgres.fields import ArrayField
from django.db import models

class Product(models.Model):
    name = models.CharField(max_length=100)
    tags = ArrayField(models.CharField(max_length=50), default=list)

# 创建一个新的产品实例
product = Product(name="Laptop", tags=["electronics", "computers"])
product.save()

# 查询具有特定标签的产品
products_with_tag = Product.objects.filter(tags__contains=["electronics"])

import json

json_data = '{"tags": ["electronics", "computers"]}'
data = json.loads(json_data)
product = Product(name="Laptop", tags=data['tags'])
product.save()

from django.contrib.postgres.indexes import GinIndex

class Product(models.Model):
    name = models.CharField(max_length=100)
    tags = ArrayField(models.CharField(max_length=50), default=list)

    class Meta:
        indexes = [
            GinIndex(fields=['tags']),
        ]
