Django 2.0，使用 check_method 导致最大递归的 URL 路由

Posted 2023-02-24

【中文标题】Django 2.0，使用 check_method 导致最大递归的 URL 路由

【英文标题】：Django 2.0, URL Routes Causing Max Recursion with check_method

【发布时间】：2018-12-18 21:16:25

【问题描述】：

我对 Django 完全陌生，将 Django“应用程序”添加到创建的 Django“项目”时遇到问题。我正在使用 Docker 和 Docker-Compose，当我尝试使用添加的“文档”应用程序构建和启动我的实例时，它会引发最大的递归错误。

如果我从项目中删除文档应用程序，则不会出现此问题，因此显然我的应用程序配置错误。

是否有人看到我在将默认 URL ('') 设置为文档中的索引视图时做错了什么？

感谢您的宝贵时间！

【问题讨论】：

你应该粘贴错误日志

【参考方案1】：

如果您使用 Django 2.0，您应该阅读此文档：https://docs.djangoproject.com/en/2.0/ref/urls/，此版本中的 url 配置已更改。但是，如果你真的想在 Django 2.0 中使用正则表达式，你可以更改：

from django.conf.urls import url

到;

from django.urls import re_path

---

你的例子；

from django.conf.urls import url

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^', Index.as_view())
    # url(r'$^', documents.views.index, name='index')
]

到;

from django.urls import re_path

urlpatterns = [
    re_path(r'^admin/', admin.site.urls),
    re_path(r'^$', Index.as_view()),
]

谢谢！我错过了迁移到 2.0 的变化。

这解决了我的问题的一部分，我遇到的另一个问题是使用表单数据的基于类的视图的错误实现。我还需要从 django 导入表单添加并通过“self.variableName”将我的变量传递给我的模板。现在它起作用了！非常感谢！
