Django的錯誤：「訪問器用於與相關領域的場衝突」

Question

當運行「蟒manage.py的runserver」，下面2個錯誤信息，則打印4次：

transcription.treatment: Accessor for field 'treatment_ptr' clashes with related field 'Treatment.treatment'. Add a related_name argument to the definition for 'treatment_ptr'. 
transcription.treatment: Reverse query name for field 'treatment_ptr' clashes with related field 'Treatment.treatment'. Add a related_name argument to the definition for 'treatment_ptr'. 

下面是我的代碼。在共享/ models.py：

class Treatment(models.Model): 
    code = RandomCharField(length=6) 
    experiment_id = models.CharField(max_length = 10, null = True) 


    base_pay = models.PositiveIntegerField(default=20) 

    def was_started_recently(self): 
     expiry_time = timedelta(minutes = 5) 
     if datetime.now() - self.time_started < expiry_time: 
      return True 

class OfferTreatment(Treatment): 
    max_offer_amount = models.PositiveIntegerField(default=50) 
    increment_amount = models.PositiveIntegerField(default=5) 

    def offer_choices(self): 
     return range(0, self.max_offer_amount + 1, self.increment_amount) 

    def is_valid_offer(amount): 
     return amount in self.offer_choices() 

    class Meta: 
     abstract = True 

在遊戲/轉錄/ models.py：

class Treatment(shared.models.OfferTreatment): 
    short_name = 'tr' 
    long_name = 'Transcription' 

有什麼建議？

Answer 1

你有兩個模型叫做治療。雖然OfferTreatment是抽象的，但共享版本的治療不是。您應該將其標記爲抽象，並將其重命名爲BaseTreatment。

或者，您可能需要進行轉錄。治療成代理模式。
