This is the minimum code you need. Then you can add fields verification, or whatever you need:
这是您需要的最少代码。然后您可以添加字段验证，或您需要的任何内容：
publisher = Publisher(name=p1,address=p2)
publisher.save()

You need to create an instance of the model class (Publisher in this case), instantiate it with the appropriate values (name and address) and then call save(), which composes the appropriates SQL INSERTstatement under the hood.
您需要创建模型类的实例（在本例中为 Publisher），使用适当的值（名称和地址）对其进行实例化，然后调用save()，它在幕后组成了适当的 SQLINSERT语句。
book = Publisher(name=p1, address=p2)
book.save()
I recommend you read the model docs.
我建议您阅读模型文档。
