Question

我有app1的 Model1

class Event(models.Model):
    name = models.CharField(max_length=100)
    description = models.TextField(max_length=500)
    eventdate = models.DateField()
    created = models.DateTimeField(auto_now_add=True)

app2的

模型1

class Register(models.Model):
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)
    select_the_event = models.ManyToManyField(Event)
    created = models.DateTimeField(auto_now_add=True)

事件数据库包含一整年的事件信息。

如何填充＆＃34; select_the_event＆＃34;哪些活动列表在接下来的60天内有效？

Answer 1

如果您有Register模型的forms.py，那么在RegisterForm类中您可以添加属性

class RegisterForm(forms.ModelForm):
    ....
    ....
    select_the_event = forms.ModelMultipleChoiceField(queryset=Event.objects.filter(
        event_date__range=[datetime.datetime.now().date(), datetime.datetime.now().date() + datetime.timedelta(60)])
)

Answer 2

在您的ModelForm中，为select_the_event的ModelMultipleChoiceField分配自定义查询集：

select_the_event = forms.ModelMultipleChoiceField(
                     queryset=Event.objects.filter(...))

使用来自另一个django模型的自定义数据填充Django ManyToManyField
