Schema is not reloaded on OAuth2 Authorization

[BramEsposito]

Describe the bug
I am running:

• Django 4.2.10
• django-oauth-toolkit 2.3.0
• djangorestframework 3.14.0
• drf-spectacular 0.27.1

I have configured drf-spectacular to authorize with OAuth2, which appears as an option in the Swagger-ui authorize popup.
However, after authorizing, the schema is not reloaded.

To Reproduce
my spectacular settings are as follows:

SPECTACULAR_SETTINGS = {
   "TITLE": "Your Project API",
    "DESCRIPTION": "Your project description",
    "VERSION": "1.0.0",
    "SERVE_INCLUDE_SCHEMA": False,
    "SERVE_PUBLIC": False,
    # OTHER SETTINGS
    "OAUTH2_FLOWS": ["clientCredentials"],
    "OAUTH2_AUTHORIZATION_URL": "/o/authorize/",
    "OAUTH2_TOKEN_URL": "/o/token/",
}

Expected behavior
I expect the schema to reload after authenticating successfully with OAuth2 as per the reloadSchemaOnAuthChange plugin

yes it should reload. not exactly sure why. I have only tested this for non-oauth cases myself.

• is there something in the browser console? warnings?
• has this ever worked before for you?
• are you sure it is not reloading? maybe it is reloading but the credentials are not injected?

Wow, you respond faster than I anticipated. 😄

I am able to authorize and reload with other authorization methods, but not with OAuth

I have solved this for myself by customising the swagger_ui plugin and adding an additional actionwrapper:

const reloadSchemaOnAuthChange = () => {
  return {
    statePlugins: {
      auth: {
        wrapActions: {
// ADD THIS BLOCK
          authorizeOauth2:(ori) => (...args) => {
            schemaAuthFailed = false;
            setTimeout(() => ui.specActions.download());
            return ori(...args);
          },
// END OF ADDED BLOCK
          authorize: (ori) => (...args) => {
            schemaAuthFailed = false;
            setTimeout(() => ui.specActions.download());
            return ori(...args);
          },
          logout: (ori) => (...args) => {
            schemaAuthFailed = false;
            setTimeout(() => ui.specActions.download());
            return ori(...args);
          },
        },
      },
    },
  };
};

Excellent! Of course they used another method. doh.

Do you want to make a PR or should I add it when I come around to it?

[BramEsposito]

I'll make a PR right away
