Python 填充下拉菜单django modelform

forms.py：

class BetaUser(ModelForm):
    Industry = forms.ModelChoiceField(queryset = homepagelaunch_industries.objects.all(), initial=1)
        class Meta:
            model = BetaUsers
            fields = ['Industry']

model.py

class BetaUsers(models.Model):
    Industry = models.CharField(verbose_name="Industry",max_length=100)
    #Industry = forms.ModelChoiceField(verbose_name="Industry", queryset=Indus.objects.all())

class Industries(models.Model):
    IndustryChoice = models.CharField(max_length=60)

def BetaUserDisplayForm(request):
    BetaUserGatherForm = BetaUser(request.POST or None)
    if request.method == 'POST':
        if BetaUserGatherForm.is_valid():
            BetaUserIndustry = BetaUserGatherForm.cleaned_data['Industry']
            BetaUserGatherForm.save()
            try:
                return HttpResponseRedirect('/BetaUserThankYou/')
            except:
                raise ('Invalid request')
        else:
            BetaUserGatherForm = BetaUser()

    return render(request, 'apage.html', {
        'BetaUserGatherForm': BetaUserGatherForm
    })

view.py

class BetaUsers(models.Model):
    Industry = models.CharField(verbose_name="Industry",max_length=100)
    #Industry = forms.ModelChoiceField(verbose_name="Industry", queryset=Indus.objects.all())

class Industries(models.Model):
    IndustryChoice = models.CharField(max_length=60)

def BetaUserDisplayForm(request):
    BetaUserGatherForm = BetaUser(request.POST or None)
    if request.method == 'POST':
        if BetaUserGatherForm.is_valid():
            BetaUserIndustry = BetaUserGatherForm.cleaned_data['Industry']
            BetaUserGatherForm.save()
            try:
                return HttpResponseRedirect('/BetaUserThankYou/')
            except:
                raise ('Invalid request')
        else:
            BetaUserGatherForm = BetaUser()

    return render(request, 'apage.html', {
        'BetaUserGatherForm': BetaUserGatherForm
    })

我只是试图从模型类的数据库列

IndustryChoice

填充

Industry

的值：

Industries

。 我做错了什么？有人能帮忙吗

我收到错误消息：

name 'homepagelaunch_industries' is not defined

---

谢谢

您遇到了什么问题/错误？很抱歉，我用错误更新了问题。我想您没有在

forms.py

中导入您的型号

homepagelaunch\u industries

，我尝试过这样做，但似乎没有解决问题。它仍然告诉我：

名称“homepagelaunch\u industries”未定义

。我更新了上面的代码。你能发布你的

表单吗？
