我有以下型号:
class Model1(models.Model):
name = models.CharField(max_length=255, null=True)
class Model2(models.Model):
model1 = models.ForeignKey(Model1, null=True)
impressions = models.PositiveIntegerField(default=0)
clicks = models.PositiveIntegerField(default=0)
spend = models.PositiveIntegerField(default=0)
user = models.ForeignKey(User, null=True)
我正在尝试创建一个视图,其中显示每个模型1登录用户与之关联的广告数量+展示次数,点击次数和支出次数。
快速模型就像:
===================================================
=Model1 Name=Model2 Count=Total Impressions=TotalClicks=
= First = 10 = 1 = 1 =
= Second = 6 = 100 = 20 =
========================================================
我一直在想着为每个model1键设置多个值的dict,但我无法弄清楚如何去做。
非常感谢任何帮助

以下内容应该可以用来获取你所指的词典:
data = {}
for m1 in Model1.objects.all():
data[m1.name] = Model2.objects.filter(model1=m1)

最后,我选择了一个存储计算字段列表的字典,如下所示:
data = {}
for m1 in Model1.objects.all():
list = []
model2s = m1.model2_set.filter(user=request.user)
if model2s:
list.append(calculated field)
list.append(Another calculated field)
data[m1.name] = list
