有没有办法在django的模型中创建一个文件数组？

from django.db import models

class MyModel(models.Model):
    files = models.FileField(upload_to='uploads/', blank=True, null=True, max_length=255)

from django.db import models

class MultipleFileField(models.Field):
    def __init__(self, *args, **kwargs):
        kwargs['max_length'] = 255
        super().__init__(*args, **kwargs)

    def get_internal_type(self):
        return 'CharField'

    def from_db_value(self, value, expression, connection):
        if value is None:
            return []
        return value.split(',')

    def to_python(self, value):
        if isinstance(value, list):
            return value
        if value is None:
            return []
        return value.split(',')

    def get_prep_value(self, value):
        if isinstance(value, list):
            return ','.join(value)
        return value

class MyModel(models.Model):
    files = MultipleFileField(upload_to='uploads/', blank=True, null=True)
