私のmodel.py .iで何が問題を引き起こす可能性があります何も試したことがありませんでした。私は私の外部キーを正しい方法を定義したと思う。私は私のforeginkeyでmemberid.user
を使用する必要がありますか、またはeffect.anyの貢献は歓迎されるでしょう。3つの問題(0沈黙)

この私のmodel.pyコード
from django.utils import timezone
from django.db import models
# Create your models here.
class tithe(models.Model):
memberid = models.ForeignKey('User')
membername = models.CharField(max_length=45)
receitcode = models.CharField(max_length=45)
tithes = models.IntegerField()
combinedoffering = models.IntegerField()
campmeetingoffering = models.IntegerField()
churchbuilding = models.IntegerField()
conference = models.IntegerField()
localchurch = models.IntegerField()
funds = models.IntegerField()
total = models.IntegerField()
created_date = models.DateTimeField(
default=timezone.now)
published_date = models.DateTimeField(
blank=True, null=True)
def publish(self):
self.published_date = timezone.now()
self.save()
def __str__(self):
return self.receitcode
class Meta:
unique_together = ["receitcode","IntegerField"]
ordering = ["published_date","membername"]
私は領収書に固有のコードを持たせたいから 'unique_together = [" receipt_code "]' – harri
'memberid'を' member_id'に、 'membername'を' member'に変更しました。これはmakeと思っていますsense now – harri
単一のフィールドをユニークにするために 'unique_together'は必要ありません。フィールド上で 'unique'オプションを使用するだけです。 – Alasdair
