我正在創建一個應用程式，我想在我的模板中顯示某個委員會的所有成員串列，但我還想顯示他們當月是否支付的狀態。現在我很困惑，因為我的會員表沒有鏈接到付款明細。我可以從付款明細表中獲取付款人的串列，但我想要的是顯示成員的所有串列，然后在他們旁邊顯示狀態。
class Members(models.Model ):
user = models.ForeignKey(Users,verbose_name='User Id', on_delete=models.CASCADE)
com = models.ForeignKey(Committees, on_delete=models.CASCADE,verbose_name='Committee Name')
mem_status = models.CharField( max_length=20,choices=MEMBER_STATUS, verbose_name='Member Status')
mem_note = models.TextField(null=True, blank=True)
class PaymentDetails(models.Model):
mem = models.ForeignKey(Members,on_delete=models.CASCADE,verbose_name='Memeber Phone no')
com = models.ForeignKey(Committees, on_delete=models.CASCADE,verbose_name='Committee Name')
payment_month = models.DateField(default=datetime.now())
payment_amount_debit = models.IntegerField(null=True,blank=True)
payment_amount_credit = models.IntegerField(null=True,blank=True)
payment_status = models.CharField(max_length=16, choices=PAYMENT_DETAILS_CHOICES)
uj5u.com熱心網友回復：
您可以做反向關系，因為 django 會自動在另一邊創建關系：
視圖.py：
def your_view(request):
members = Members.objects.all().select_related()
members_context = [member.paymentdetails_set.values("payment_month", "payment_status") for member in members]
return render(request, 'your_template', {'members': members_context})
your_template_tag.py：
from django.template.defaulttags import register
@register.filter
def get_item(dictionary, key):
return dictionary.get(key)
your_template.html：
{% for member in members %}
<p> Payment Month: {{ member|get_item:"payment_month" }}</p>
<p> Payment Status: {{ member|get_item:"payment_status" }}</p>
{% endfor %}
