Django REST Framework在文件之间共享类实例 [英] Django REST Framework share class instance between files

问题描述

我的apps.py的 ready（）方法中包含一些代码，该方法使用authlib模块加载一些Oauth提供程序。基本上我是这样做的（apps.py）：

I have some code in my apps.py's ready() method that loads some Oauth providers using the authlib module. Basically I am doing this (apps.py):

from django.apps import AppConfig
from authlib.integrations.django_client import OAuth
from django.core.cache import caches

class ApiConfig(AppConfig):
    name = 'api'

    def ready(self):
        import api.receivers
        defaultcache = caches['default']
        from .modules.oauth import fetch_token
        from .models import OauthProvider, OAuth2Token

        oauth = OAuth(fetch_token=fetch_token)
        print('settings oauthproviders')
        allproviders = OauthProvider.objects.all()
        for provider in allproviders:
            oauth.register(
                name=provider.name,
                client_id=provider.client_id,
                client_secret=provider.client_secret_decrypted,
                access_token_url=provider.access_token_url,
                access_token_params=provider.access_token_params,
                authorize_url=provider.authorize_url,
                authorize_params=provider.authorize_params,
                api_base_url=provider.api_base_url,
                client_kwargs=eval(provider.client_kwargs),
            )

        print(OAuth2Token.objects.get(name='enelogic'))
        defaultcache.set('oauth', oauth)
        #defaultcache.get('oauth') # <--- this line gives error

错误：

Fatal Python error: Cannot recover from stack overflow.

此命令注册了一些可以作为使用 oauth 变量（例如 oauth.get_authorization_url（）），它可以为我提供该Oauth提供程序的授权URL。

This registers some oauth credentials (info) that can be used using the oauth variable (for example oauth.get_authorization_url() which gets me the authorize URL for that Oauth Provider.

现在，我有很多不同的文件（我将views.py拆分为多个文件）。如何在那些文件中访问此oauth变量？我曾经尝试过使用django缓存，但是当我尝试访问该变量时却出现了一个奇怪的溢出错误。

Now, I have a lot of different files (I split my views.py into multiple files). How can I access this oauth variable in those files? I have tried with django caches, but then I get a weird overflow error when I try to access the variable.

您会如何建议？

oauth类在文件中本地运行良好，我只需要将其传输到其他文件

The oauth class is working fine locally in the file, I just need to transfer it to some other file

推荐答案

为什么不提取该文件

# oauth_providers.py

from authlib.integrations.django_client import OAuth

from .modules.oauth import fetch_token
from .models import OauthProvider, OAuth2Token


def register_providers(oauth):
    print('settings oauthproviders')
    allproviders = OauthProvider.objects.all()
    for provider in allproviders:
        oauth.register(
            name=provider.name,
            client_id=provider.client_id,
            client_secret=provider.client_secret_decrypted,
            access_token_url=provider.access_token_url,
            access_token_params=provider.access_token_params,
            authorize_url=provider.authorize_url,
            authorize_params=provider.authorize_params,
            api_base_url=provider.api_base_url,
            client_kwargs=eval(provider.client_kwargs),
        )

    print(OAuth2Token.objects.get(name='enelogic'))

oauth = OAuth(fetch_token=fetch_token)

# apps.py
from django.apps import AppConfig


class ApiConfig(AppConfig):
    name = 'api'

    def ready(self):
        from .oauth_providers import oauth, register_providers
        register_providers(oauth)

现在，您可以通过简单的导入在视图中使用它

And now you can use it in your views by simple import

# views.py

from .oauth_providers import oauth

# do whatever with oauth

是的，有些警告将是bal变量（因此，请勿尝试更改，我认为您不需要这样做），也不要尝试将文件导入到 models.py 中应在应用程序 ready（）之后导入。

Yes, there are some caveats it will be a global variable (so don't try to change, I don't think you'll need to) and don't try to import the file in your models.py since this should be imported after the app is ready().

这篇关于Django REST Framework在文件之间共享类实例的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
