我需要你的帮助.问题:我有一个用于创建新用户的模板,视图和表单,如果我在注册时出现相同的错误(例如:password1!= password2),我应该在模板中看到错误,但它们不是.SOS!

观点:

def registration(request):
if request.method == "POST" :
    form = UserCreationForm(request.POST, request.FILES)
    if form.is_valid():
        print "form is valid"
        form.save()
        return render_to_response("action_succes.html")
    else:
        print form.is_valid()
        print form.errors
        form = UserCreationForm(request.POST)
else:
    form = UserCreationForm()

args = {}
args.update(csrf(request))
form = UserCreationForm()
#args["form"] = UserCreationForm()
#return render_to_response("registration.html", args)
return render(request, "registration.html", {'form':form})

模型:

class User(AbstractBaseUser):
email = models.EmailField(
    verbose_name='Email address',
    max_length=45,
    unique=True,
    db_index=True,
)
username = models.TextField(verbose_name='Nick', max_length=15, unique=True)
profession = models.TextField(verbose_name='Profession', max_length=15)
avatar = models.FileField(upload_to=get_upload_file_name, blank=True, null=True)
profile_vkontakte = …

需要你的帮助.我尝试使用mongoengine,烧瓶,烧瓶登录.

我的模特:

class Post(db.Document):
   text = db.StringField(max_length=240)
   pub_date = db.DateTimeField(default=datetime.datetime.now)
   author = db.ReferenceField(Member)

我得到当前用户(flask-login):

from flask.ext.login import current_user

比在views.py中:

new_post = Post()
    new_post.text = 'bla-bla'
    #new_post.author = current_user                                 #- DON`T WORK
    new_post.author = Member.objects.get(id=current_user.id)        #-WORK (WHY?)
    new_post.save()

有什么错new_post.author = current_user,如果new_post.author = Member.objects.get(id=current_user.id)-工作正常.

如果尝试new_post.author = current_user- 获取错误:

mongoengine.errors.ValidationError
ValidationError: ValidationError (Post:None) (A ReferenceField only accepts DBRef or documents: ['author'])

谢谢,人.
