AttributeError: module 'purchase.views' has no attribute 'viewPDF'
我在按照教程进行操作后遇到此错误，我对此还很陌生，但无法弄清楚哪里出了问题，因为我已经检查过、双重检查过、三次检查过等等。这可能是一个简单的错误，但对我这个初学者来说并不简单 ;)

Because Django’s URL resolver expects to send the request and associated arguments to a callable function, not a class, class-based views have an as_view() class method which returns a function that can be called when a request arrives for a URL matching the associated pattern.
将你的urls.py从
path('pdf_view/', views.viewPDF, name="pdf_view")
对此
path('pdf_view/', views.viewPDF.as_view(), name="pdf_view")
我在按照教程进行操作后遇到此错误，我对此还很陌生，但无法弄清楚哪里出了问题，因为我已经检查过、双重检查过、三次检查过等等。这可能是一个简单的错误，但对我这个初学者来说并不简单 ;)
