Question

首次尝试通过扩展用户模型来创建学生用户。

问题：点击注册btn ieLogin（btn）代替   重定向到home它显示以下内容：NameError at / register /   ...名称'用户'未定义

文件“E：\ ifb299 \ tutorial2 \ accounts \ views.py”，第33行，在寄存器中       Students.objects.create（user = user）NameError：未定义名称'user'[25 / Mar / 2018 14:38:07]“POST / register / HTTP / 1.1”500 67801

不确定我做错了什么，为什么Students.objects.create（用户=用户）错了，我该如何解决呢？

    # Once register page loads, either it will send to the server POST data (if the form is submitted), else if it don't send post data create a user form to register
    if request.method == "POST":
        form = RegistrationForm(request.POST)
        if form.is_valid():
            form.save()
            Students.objects.create(user=user)
            return redirect('../home/')
    else:
        #  Create the django default user form and send it as a dictionary in args to the reg_form.html page.
        form = RegistrationForm()
    args = {'form': form}
    return render(request, 'accounts/reg_form.html', args)

     # Handle post request - if the user submits a form change form details and pass the intance user
    if request.method == 'POST':
        form = EditProfileForm(request.POST, instance=request.user)

        if form.is_valid():
            form.save()
            return redirect('../profile')
    # Handles the get request - if no post info is submitted then get the form and display it on the edit profile page. 
    else:

        user.last_name = self.cleaned_data['last_name']
        user.email = self.cleaned_data['email']

        if commit:
            user.save()

        return user

#  Inherits from UserChangeForm class - we keep everything i.e. methods, functionality same but change the things we want to show - connected to the User model 
class EditProfileForm(UserChangeForm):

    class Meta:
        model = User
        # Create fields variable get has all the fields we want to show 
        fields = (
            'email',
            'first_name',
            'last_name',
            'password'
        )

Answer 1

首先，您没有将form.save()的返回值保存到变量user。

第二，您的模型user没有字段Student。
