爲什麼django object.get會在何時引發DoesNotExist？

Question

我有這個奇怪的例外：對象在我的數據庫存在，get不工作，但過濾器是...

(Pdb) p ProjectPhase.objects.get(slug='done-complete') 
*** DoesNotExist: DoesNotExist('ProjectPhase matching query does not exist.',) 

(Pdb) p ProjectPhase.objects.all().filter(slug='done-completed') 
[<ProjectPhase: 8 - Done - Completed>] 

任何提示？

Answer 1

兩種文本都不同。首先是：done-complete和第二個done-completed。

所以，

ProjectPhase.objects.get(slug='done-completed') 

應工作
