I'm creating an API using peewee as the ORM and I need the ability to convert a peewee model object into a JSON object to send to the user. Does anyone know of a good way to do this?

推荐答案

您可以执行以下操作:

class MyModel(peewee.Model):

  def __str__(self):
    r = {}
    for k in self._data.keys():
      try:
         r[k] = str(getattr(self, k))
      except:
         r[k] = json.dumps(getattr(self, k))
    return str(r)


class User(MyModel):
    email = CharField()
    status = CharField(default="enabled")
    firstname = CharField()
    lastname = CharField()
    class Meta:
        database = db
