如何在Django ORM中映射PostgreSQL数组字段

pip install psycopg2

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'mydatabase',
        'USER': 'myuser',
        'PASSWORD': 'mypassword',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

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

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

from myapp.models import MyModel

my_model = MyModel.objects.create(tags=['tag1', 'tag2', 'tag3'])

{% for tag in my_model.tags %}
    <span>{{ tag }}</span>
{% endfor %}
