对象不可脚本化意味着什么? [英] What does it mean for an object to be unscriptable?

问题描述

我不知道这里发生了什么...我只想检查模型字段的值，然后相应地更新它...任何帮助或见解表示赞赏！

I don't know what's going on here... I just want to check the value of a model field and then update it accordingly... any help or insight is appreciated!

型号:

class UserProfile(models.Model):
    user = models.ForeignKey(User, unique=True)
    beta = models.CharField(max_length=1, blank=True, null=True)

查看:

from internal.accounts.models import UserProfile
from django.contrib.auth.models import User
@login_required    
def beta_testers(request):
    user = User.objects.get(username=request.user.username)
    user_profile = user.get_profile()

    count = UserProfile.objects.filter(beta='1').count()

    if count < 50 and not user_profile['beta']:
        user_profile['beta'] = '1'
        user_profile.save()

错误:

TypeError at /utilities/beta-signup/
'UserProfile' object is unsubscriptable
Request Method: GET
Request URL:    http://localhost/utilities/beta-signup/?x=1&y=15
Django Version: 1.2.1
Exception Type: TypeError
Exception Value:    
'UserProfile' object is unsubscriptable
Exception Location: C:/djangointernalcms_helperviews.py in beta_testers, line 284

推荐答案

错误是unSUBscriptable".您的 user_profile 对象不是字典.使用 user_profile.beta，而不是 user_profile['beta'].

The error is "unSUBscriptable". Your user_profile object isn't a dictionary. Use user_profile.beta, not user_profile['beta'].
