大家好。我想知道如何通过定义的会话列表中的项目数来更改模型字段的值
我已经制作了一个个人档案模型(用户模型是OneToOne字段) 并在“ models.py;
在view.py中,我创建了一个名为“ answer_list”的会话,该会话存储了用户提供的所有正确答案的列表。
class UserProfile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='profile')
level = models.CharField(max_length=1, choices=[('Newbie', 'N'), ('Regular', 'R'), ('Expert', 'E')], default='Newbie')
def index(request):
if 'answer_list' in request.session: #answer_list has been created previously #request.session['answer_list'] = []
ok = request.session['answer_list']
print (ok) #just to check the content of 'answer_list' which is correct
if len(ok) == 4:
user=request.user
user.profile.level = 'R'
user.profile.save()
return render(request, 'index.html', {})
一旦会话“ answer_list”中的项目数达到4,我希望user.profile.level的值从“新手”更改为“常规”。
答案 0 :(得分:0)
尝试
UserProfile.object.filter(user=request.user).update(level='R')
