drf-spectacular使用错误的AutoSchema生成Swagger

问题描述

以前，我使用的是drf-yasg，但想更新以使用OpenAPI3。我试图切换到drf-spectacular。在instruction之后，我运行了pip install drf-spectacular，删除了对drf-yasg包的所有引用，并按如下所示更新了Settings.py：

INSTALLED_APPS = [ 
    ...
    "drf_spectacular",]


REST_FRAMEWORK = {
    "DEFAULT_SCHEMA_CLASS": "drf_spectacular.openapi.AutoSchema",}

当我使用CLI生成架构时，出现以下提示AssertionError。如果有人以前遇到过这个问题并且有任何见识，将不胜感激！

我正在使用Python 3.7，Django 3.0，Django Rest Framework 3.11和DRF Spectacular 0.10.0。

AssertionError: Incompatible AutoSchema used on View. Is DRF's DEFAULT_SCHEMA_CLASS pointing to "drf_spectacular.openapi.AutoSchema" or any other drf-spectacular compatible AutoSchema?

解决方法

请更新Django Rest Framework 3.11至3.12，它将起作用。
