我在django中使用postgresql,并试图使用 ArrayField(models.EmailField(max_length=200)) . 但我最终得到了一个 500 error code(TypeError) 提供无效电子邮件地址时。

如何验证ArrayField中的每个电子邮件。我尝试在序列化程序和模型中编写验证方法。但没什么帮助。验证ArrayFields的正确方法是什么?我使用的是django 2.1和python 3.6

错误的回溯如下…请查看

模特儿

billing_emails=arrayfield(models.emailfield(max_length=200))

company=models.onetoonefield(company,on_delete=models.cascade)
