DRF-壮观 找不到检查员类

Question

我正在尝试设置drf-special，以便为我的djangorestframework API生成AutoSchema。

我已经按照Readme中的解释进行了设置，例如，在已安装的应用程序中，版本="~=0.11.1〃；，并且在其余框架设置中如下：

REST_FRAMEWORK = {
...,
'DEFAULT_SCHEMA_CLASS': ('drf_spectacular.openapi.AutoSchema',),
}

我的djangorest框架是3.12版本。运行以下命令时出现错误：./manage.py spectacular --file schema.yml

下面是我的一个示例视图：

class LinkListView(ListView):
permission_classes = [AllowAny]
template_name = "core/linklist.html"
context_object_name = "link_list"
def get_queryset(self):
return Org.objects.all()

在阅读了一堆关于模式的文章后，我想我有其他一些库与此相冲突，或者以前的一些其他招摇过市的替代方案与此相矛盾。基于错误，这有意义吗？有什么我想试试的吗？

谢谢！

这很可能只是一个小的设置问题。您将DEFAULT_SCHEMA_CLASS定义为字符串的元组，而不仅仅是字符串。Django可能将其解析为一个列表/元组，其中一个类作为项。因此，错误消息是有意义的，因为元组不是类。我希望这能解决你的问题。应该是这样的：

REST_FRAMEWORK = {
# YOUR SETTINGS
'DEFAULT_SCHEMA_CLASS': 'drf_spectacular.openapi.AutoSchema',
}
