Saya mendapatkan TransactionManagementError ketika mencoba untuk menyimpan contoh model Pengguna Django dan dalam sinyal post_save, saya menyimpan beberapa model yang memiliki pengguna sebagai kunci asing.
Konteks dan kesalahannya cukup mirip dengan pertanyaan ini django TransactionManagementError saat menggunakan sinyal
Namun, dalam kasus ini, kesalahan hanya terjadi saat pengujian unit .
Ini bekerja dengan baik dalam pengujian manual, tetapi pengujian unit gagal.
Apakah ada sesuatu yang saya lewatkan?
Berikut cuplikan kode:
