错误：一个或多个模型未验证，在定义中添加 related_name 参数

Question

在我的应用程序中运行“manage.py validate”时出现此错误。

错误：一个或多个模型未验证： ipn.paypalipn：字段“自定义”的访问器与相关字段冲突 '演员.paypalipn_set'。在定义中添加一个 related_name 参数 '风俗'。 dashboard.paypalipn：字段“自定义”的访问器与相关字段冲突 '演员.paypalipn_set'。在定义中添加一个 related_name 参数 '自定义'。

这是我在 Dashboard/models.py 下获得的另一个 model.py

@csrf_exempt
def show_me_the_money(sender, **kwargs):

ipn_obj = sender

actor_id = ipn_obj.custom

if ipn_obj.payment_status == "Completed":

    from actors.models import Actor
    from commerce.models import Transaction

    actor = Actor.objects.get(id=actor_id)

    accountdetails = actor.account_set.latest('pk')

    signupbonus = 0


    transaction = Transaction()
    transaction.actor = actor
    transaction.amount = ipn_obj.mc_gross
    transaction.currency = ipn_obj.mc_currency
    transaction.transaction_flag = 'paid'
    transaction.transaction_type = 'deposit'
    transaction.payment_method = 'Paypal'
    transaction.payment_reference = ipn_obj.txn_id
    transaction.payment_message = 'OK'
    transaction.transaction_date = timezone.now()
    transaction.UserIp = actor_ip()
    transaction.save()           

    currentamount = accountdetails.balance
    accountdetails.balance = float(signupbonus) + float(currentamount) + float(ipn_obj.mc_gross)
    accountdetails.save()

payment_was_successful.connect(show_me_the_money)

在models.py中，演员

Answer 1

我认为您的项目有两个 models.py 文件，其中一个在仪表板目录下，另一个在 ipn 目录下。

在这两个models.py中，你有一个名为“Paypalipn”的模型，这两个模型有一个名为“custom”的字段和相关的“Actor”模型。

所以当 Django 尝试从“Actor”模型建立反向关系时，它们都是相同的“Actor.paypalipn_set”

因此，您需要在两个模型（dasboard/paypalipn 和 ipn/paypalipn）中为“自定义”字段的定义添加“related_name”参数
