如何在django中保存数组数据？

from django.db import models

class MyModel(models.Model):
    array_field = models.CharField(max_length=255)

# 保存数组数据
my_model = MyModel()
my_model.array_field = ','.join(my_array)
my_model.save()

# 获取数组数据
my_model = MyModel.objects.get(pk=1)
array_data = my_model.array_field.split(',')

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

class MyModel(models.Model):
    array_field = JSONField()

# 保存数组数据
my_model = MyModel()
my_model.array_field = my_array
my_model.save()

# 获取数组数据
my_model = MyModel.objects.get(pk=1)
array_data = my_model.array_field

from django.db import models

class MyModel(models.Model):
    array_field = models.ManyToManyField(OtherModel)

# 保存数组数据
my_model = MyModel()
my_model.save()
my_model.array_field.set(my_array)

# 获取数组数据
my_model = MyModel.objects.get(pk=1)
array_data = my_model.array_field.all()
