Django报错： 'OrderingFilter' object has no attribute 'get_schema_fields'

Django报错： 'OrderingFilter' object has no attribute 'get_schema_fields'

• 在使用django restframework，我们通过include_docs_urls，生成接口文档。

from rest_framework.documentation import include_docs_urls

urlpatterns = [
    # 显示你当前接口信息
    # 需要安装coreapi
    path('docs/', include_docs_urls(title='接口文档')),

] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

• 需要安装coreapi

pip install coreapi==2.33

• 但仍然报错，报错信息

File "J:\pos\lib\site-packages\rest_framework\schemas\inspectors.py", line 217, in get_link
    fields += self.get_filter_fields(path, method)
  File "J:\pos\lib\site-packages\rest_framework\schemas\inspectors.py", line 413, in get_filter_fields
    fields += filter_backend().get_schema_fields(self.view)
AttributeError: 'OrderingFilter' object has no attribute 'get_schema_fields'

• pycharm进入 inspectors.py更改代码

for filter_backend in self.view.filter_backends:
	try:
		fields += filter_backend().get_schema_fields(self.view)
	except:
		pass
return fields

• 接口文档生成
