Джанго ошибки manage.py значения метания

Question

Вот трассировки стека я получаю, когда я бег любого manage.py команды

Я пытался Google ошибку или искать переполнения стека для некоторых ответов, но я не могу понять, что я сделал неправильно.

EDIT 1: После внесения предложений по изменению родственного имени для каждого из них я изменил их на sess_1 sess_2 и sess_3 с уважением. но теперь я получаю эту ошибку, которую я пытался избежать.

Answer 1

Я sugest попытке переписать код:

sector1_moist_prof = models.OneToOneField(MoistureProfileDict, related_name="%(class)") 
sector2_moist_prof = models.OneToOneField(MoistureProfileDict, related_name="%(class)") 
sector3_moist_prof = models.OneToOneField(MoistureProfileDict, related_name="%(class)") 

Вы объявлены три один на один отношений, но дать им все одно обратное имя, которое не обязательно - если вы будете пытаться сделать обратное - Джанго ОРМ не будет знать, что exacly отношение использовать

Try:

sector1_moist_prof = models.OneToOneField(MoistureProfileDict, related_name="sess_1") 
sector2_moist_prof = models.OneToOneField(MoistureProfileDict, related_name="sess_2") 
sector3_moist_prof = models.OneToOneField(MoistureProfileDict, related_name="sess_3") 

Answer 2

Вы упускаете в 'S' в форматере для related_name: %(class)s.

Использование

sector1_moist_prof = models.OneToOneField(MoistureProfileDict, \ 
related_name="%(class)s") 

вместо

sector1_moist_prof = models.OneToOneField(MoistureProfileDict, \ 
related_name="%(class)") 

(То же самое для других полей.)

Answer 3

Из TRACEBACK я могу сказать, что проблема связана с related_name с. Я думаю, что вы должны написать %(class)s вместо %(class) в них
