Django錯誤：“字段訪問器與相關字段發生沖突”

Question

當我運行“ python manage.py runserver”時，以下2條錯誤消息被打印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shared / models.py中：

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games / transcription / models.py中：

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

有什么建議么？

Answer 1

您有兩個稱為“治療”的模型。 盡管OfferTreatment是抽象的，但Treatment的共享版本卻不是。 您可能應該將其標記為抽象，然后將其重命名為BaseTreatment。

或者，您可能需要進行轉錄。將其處理為代理模型。
