Question

我的models.py文件中有模型名为模板

class template(models.Model):
    id = models.AutoField(primary_key=True)
    customer_id = models.ForeignKey(customer,on_delete=models.CASCADE)
    name = models.CharField(max_length=255,blank=False,null=False)
    data = RichTextField()

    def __unicode__(self):
        return self.name

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return reverse("templatedetail",kwargs={"id": self.id})

然后我在我的views.py

中导入此模型

from .models import template

然后当我尝试获取方法中的所有对象时

def assign_user_template(request,email=None):
    if 'credentials' not in request.session:
        return redirect('/oauth2callback/')

    credentials = client.OAuth2Credentials.from_json(request.session['credentials'])
    if credentials.access_token_expired:
        return redirect('/oauth2callback/')
    else:
        http = httplib2.Http()
        http = credentials.authorize(http)
        user_service = build('admin','directory_v1',http=http)
        user_profile = user_service.users().get(userKey=email).execute()
        user_profile_email = user_profile.get('primaryEmail')
        user_profile_service = build('oauth2', 'v2', http=http)
        user_info = user_profile_service.userinfo().get().execute()
        user_email = user_info.get('email')
        admin_service = build('admin','directory_v1',http=http)
        admin_profile = admin_service.users().get(userKey=user_email).execute()
        customer_id = admin_profile.get('customerId')
        templates = template.objects.filter(customer_id = customer_id)
        template_user_object = template_user_map.objects.filter(user_email = email)
        if template_user_object:
            template_user_object = template_user_map.objects.get(user_email = email)
            template_user = template_user_object.template_id            
        else:
            template_user = None
        if request.method == 'POST':
            form = TemplateSelectForm(request.POST)
            if form.is_valid():
                template = form.cleaned_data['selected_template']
                user_template_map_object = template_user_map(user_email=user_profile_email,template_id=template)
                user_template_map_object.save()
                user_profile = user_service.users().get(userKey=user_profile_email).execute()
                customer_id = user_profile.get('customerId')
                customer_object = customer.objects.get(id = customer_id)
                //some code
                return HttpResponseRedirect('/userlist/')
        else:
            form = TemplateSelectForm()
        return render(request,'assign_user_template.html',{"form":form})

但是我得到了这个本地变量＆＃39;模板＆＃39;在赋值错误之前引用。模型以正确的方式导入。当我在不同的模型上尝试这个时，它没有给出任何错误。

完全追溯

Answer 1

 template = form.cleaned_data['selected_template']

我认为它的名称与类模板相冲突。盖上所有课程。

局部变量＆＃39;模板＆＃39;在分配之前引用
