Question

我有两个模型如下：

class Types_of_Expenditures(models.Model):
    Expenditure_owner = models.CharField(default="None",max_length=50)
    Expenditure_Type = models.CharField(default="Miscellaneous",max_length=50)
    Expenditure_Type_Description = models.CharField(max_length=200)
    def __unicode__(self):
        return self.Expenditure_Type

class Expenditure(models.Model):
    exp_owner= models.CharField(default='None',max_length=50)
    exp_date = models.DateTimeField("Expenditure_Date")
    description = models.CharField(max_length=1000)
    amount = models.FloatField(default=0)
    currency = models.CharField(max_length=15,default="MYR",editable=True)
    exp_pocket = models.ForeignKey(Pockets, null=True, blank=True)
    exp_type = models.ForeignKey(Types_of_Expenditures)
    class Meta:
        unique_together = ('exp_date', 'description',)
    def __unicode__(self):
        return self.description

对于以上2种型号，我使用以下2种形式：

class Types_of_Expenditures_Form(forms.ModelForm):
    class Meta:
        model = Types_of_Expenditures

class ExpenditureDeleteForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(ExpenditureDeleteForm, self).__init__(*args, **kwargs)
        self.fields['exp_pocket'].widget = forms.TextInput(attrs={'readonly':'readonly'})
        self.fields['exp_type'].widget = forms.TextInput(attrs={'readonly':'readonly'})
        self.fields['amount'].widget = forms.TextInput(attrs={'readonly':'readonly'})
        for f in self.fields:
            self.fields[f].widget.attrs['readonly'] = "readonly"
    class Meta:
        model = Expenditure
        exclude = ['exp_owner','currency']
        fields = ['exp_date', 'description', 'exp_type', 'amount','exp_pocket']

在我看来，我称之为：

ExpDeleteFormSet = modelformset_factory(Expenditure,extra=0,
            can_delete=True,fields = ['exp_date', 'description', 'exp_type', 'amount','exp_pocket'],form=ExpenditureDeleteForm)
formset = ExpDeleteFormSet(queryset=Expenditure.objects.filter(exp_owner=str(request.user)))
return render_to_response('expenditure.html', {'formset':formset}, context)

现在呈现的formset如下图所示：

问题/问题： 正如您在图像中看到的那样，Type被编号为1或2。这个1在Types_of_Expenditure中具有相应的值Miscellaneous，而2具有其他内容，依此类推。是否可以将类型显示为Types_of_Expenditure的相应值？

我尝试过各种各样的事情，例如使用Baseformset尝试使用查询集但无法找到如何操作？

尝试了什么

使用如下的inlineformset_factory，但这样做会在模板中呈现任何内容：

ExpDeleteFormSet = inlineformset_factory(Types_of_Expenditures, 
                                     Expenditure, fk_name="exp_type",
                                     fields = ['exp_date', 'description', 'exp_type', 'amount','exp_pocket'],
                                     can_delete=True,form=ExpenditureDeleteForm)

替代方案效果很好： 我现在使用的另一种方法是将Expenditure_Type本身作为主键，但是我会寻找原始问题的答案：

Expenditure_Type = models.CharField(primary_key=True,max_length=50)

是否可以在modelformset中显示外键的值而不是id
