覆盖加密数据的django-admin编辑表单字段值

问题描述

我在加密的数据库中有值，我如何覆盖django的管理员编辑表单，以便这些字段可以显示解密的数据？只是为了澄清我知道如何解密值，我只需要知道如何获得解密的值到字段中。是否有可能使用的change_view方法的django信号？

解决方案

可以覆盖您使用的模型形式modeladmin ，在这种情况下我会考虑使用，并加密加密/解密成数据库序列化/反序列化

I have values in a database that are encrypted, how can I override django's admin edit form so that the fields can display the decrypted data? Just to clarify I know how to decrypt the values I just need to know how to get the decrypted values into the fields. Is there a django signal for the change_view method that I could perhaps use?

解决方案

while it's possible to override the modelform used by your modeladmin (docs), in this case i would consider using a custom field type, and building in the encryption/decryption into the database serialisation/deserialisation
