我的目的是动态生成 Django 模型。
我使用以下代码来创建模型。

def create_model(name, fields=None, app_label='', module='', options=None, admin_opts=None):
  class Meta:
    # Using type('Meta', ...) gives a dictproxy error during model creation
    pass

  if app_label:
    # app_label must be set using the Meta inner class
    setattr(Meta, 'app_label', app_label)

  # Update Meta with any options that were provided
  if options is not None:
    for key, value in options.iteritems():
        setattr(Meta, key, value)

  # Set up a dictionary to simulate declarations within a class
  attrs = {'__module__': module, 'Meta': Meta}

  # …
