如何使用RemovedInNextVersionWarning？

Question

我已经写了一个库Django，我想更新它。但是我需要对使用它的人说这个功能将来会被删除，我该怎么说呢？你知道吗

class ModelAdmin(admin.ModelAdmin):
      def __init__(self, *args, **kwargs):
          super(ModelAdmin, self).__init__(*args, **kwargs)
          self.formfield_overrides = overrides
          warnings.filterwarnings(
              'ignore',
              'please use "ModelAdminJalaliMixin". example: class YourClass (admin.ModelAdmin, ModelAdminJalaliMixin):',
               RemovedInNextVersionWarning
          )

Answer 1

from django.utils.deprecation import RemovedInNextVersionWarning
import warnings     
warnings.warn('WarningString', RemovedInNextVersionWarning)

warnings是python模块，RemovedInNextVersionWarning是在DeprecationWarning上扩展的django类
