创建一个使用两个不同模型属性的表单

我认为使用2个表单没有问题,但我有点不确定如何继续(也许我不需要!)。

模型如下所示:

class PersonBenefit(models.Model):
     benefit = models.ForeignKey(Benefit, null=True)
     user = models.ForeignKey(User)

class Friend(models.Model):
     first_name = models.CharField(max_length=40)
     last_name = models.CharField(max_length=40)
     has_benefit = models.BooleanField(default=False)
     ben_id_num = models.CharField(max_length=10, blank=True, null=True)
     person = models.ForeignKey(User)

 #good, better, best
class BenefitType(models.Model):
    name = models.CharField(max_length=25)

    def __str__(self):
        return self.name


class Benefit(models.Model):
    type = models.ForeignKey(BenefitType)
    name = models.CharField(max_length=25)

表格。py看起来像这样:

class GoodBenefitForm(forms.Form):
    benefit = forms.ModelChoiceField(
        queryset=Benefit.objects.filter(type__name='Good'),
        widget = forms.Select(attrs={'class':'g-1-3'})
    )
 # THIS SHOWS A LIST OF ALL THE FRIENDS FOR THIS USER - DISPLAYS THEIR NAMES NICELY WITH CHECKBOXES
    friend = forms.ModelMultipleChoiceField(
        queryset = Friend.objects.none(),
        widget = forms.CheckboxSelectMultiple(),
    )
 # I WANT THIS TO BE A BUNCH OF TEXTBOXES INSTEAD OF CHECKBOXES - ONE FOR EACH FRIEND FOR THE USER
    friend_group_id = forms.ModelMultipleChoiceField(
        queryset = Friend.objects.none(),
        widget = forms.CheckboxSelectMultiple(),
    )

    def __init__(self, *args, **kwargs):
        self.user = kwargs.pop('user')
        queryset = Friend.objects.filter(person=self.user)
        super(FriendBenefitForm, self).__init__(*args, **kwargs)
        self.fields['friend'].queryset = queryset
        self.fields['friend_group_id'].queryset = queryset

ben_id_num

再一次,在阅读之后,我认为拥有两个单独的表单可能是最好的方式,但我不确定我是否只是在表单中做了一些愚蠢的事情。py原样,只需1个表单即可。

这基本上是:

对于每个“朋友”,显示一个小表单,其中有一个复选框,该复选框后面紧跟着朋友的名字和一个文本字段(对应于他们的 ben\u id\u num
