我論文模型和管理模型顯示beloy增加額外排在Django聯模板
我想在模型交易,顯示總金額(那是量字段的總和)
有不是在Inline中更改列表的方法如何執行此操作
class TransactionAdmin(admin.ModelAdmin):
inlines = [TransactionAmountInline, AmountPaidInline, PhotosInline]
fields = ('customer', 'title', 'description', 'created_at')
readonly_fields = ('updated_at',)
list_display = ('title', 'customer')
class AmountPaidInline(admin.TabularInline):
model = AmountPaid
extra = 0
class AmountPaid(models.Model):
transaction = models.ForeignKey(Transactions)
description = models.TextField(null=True)
amount = models.DecimalField(max_digits=19, decimal_places=4)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
謝謝您的回答居然是我我要的是顯示在變化形式sum_amount(當你點擊交易鏈接)我知道我可以覆蓋更改列表視圖並將總額添加到額外的上下文中,但我想要顯示總金額顯示在其將要顯示的AmountPaidInline表單中 – user2388404 2014-12-10 18:55:16
簡而言之,我想在內聯中添加另一行以顯示AmountPaind模型中的總金額 – user2388404 2014-12-10 19:02:20
