Bir Django kullanıcı modeli örneği kaydetmeye çalışırken TransactionManagementError alıyorum ve onun post_save sinyal, ben yabancı anahtar olarak kullanıcı olan bazı modelleri kaydediyorum.
Bağlam ve hata bu soruya oldukça benzer django TransactionManagementError sinyalleri kullanırken
Ancak, bu durumda, hata yalnızca birim sınama sırasında ortaya çıkar .
Manuel testte iyi çalışır, ancak birim testleri başarısız olur.
Kaçırdığım bir şey var mı?
