Question

我使用User的其他字段创建了一个新模型。

models.py：

class UserProfile(models.Model):

        user = models.OneToOneField(User)
        email = models.CharField(max_length=50)
        birthday = models.DateField(u'Birthday', blank=True, null=True)
        avatar = models.ImageField(Avatar', upload_to='profile/avatar', blank=True)

        def __unicode__(self):
                return self.user

然后我为用户创建注册表单：

class RegistrationForm(ModelForm):
        username = forms.CharField(label=(u'Enter Your Username'))
        email = forms.EmailField(label=(u'Enter Your E-mail'))
        password = forms.CharField(label=(u'Enter Password'), widget=forms.PasswordInput(render_value=False))
        password1 = forms.CharField(label=(u'Verify Your Password'), widget=forms.PasswordInput(render_value=False))

        class Meta:
                model = UserProfile
                exclude = ('user',)

        def clean_email(self):
                email = self.cleaned_data['email']
                try:
                        User.objects.get(email=email)
                except User.DoesNotExist:
                        return email
                raise forms.ValidationError("User with same e-mail is already exist, please type another email")

        def clean_password(self):
                password = self.cleaned_data.get('password')
                password1 = self.cleaned_data.get('password1')

                if not password1:
                        raise forms.ValidationError("You have ti verify your password")
                if password != password1:
                        raise forms.ValidationError("Your passwords doesn't match")
                return password1

这是我对注册页面的看法：

def UserProfileRegistration(request):
        if request.user.is_authenticated():
                return HttpResponseRedirect('/info/')
        if request.method == 'POST':
                form = RegistrationForm(request.POST)
                if form.is_valid():
                        user = User.objects.create_user(username=form.cleaned_data['username'], email=form.cleaned_data['email'], password=form.cleaned_data['password'])
                        user.save()
                        user_profile = UserProfile(user=user)
                        user_profile.save()
                        return HttpResponseRedirect('/info/')
                else:
                        return render(request, 'profiles/registration.html', {'form':form})
        else:
                form = RegistrationForm()
                context = {'form':form}
                return render (request, 'profiles/registration.html', context)

看起来像我的html页面：

 <form action="." method="POST">
 {% csrf_token %}
 {% if form.username.errors %}
    {% for error in form.username.errors %}
       <p>This field is required</p>
    {% endfor %}
 {% endif %}
 {{ form.username.label_tag}}
 {{ form.username }}
 {% if form.email.errors %}
    {% for error in form.email.errors %}
       <p>This field is required</p>
    {% endfor %}
 {% endif %}
 {{ form.email.label_tag }}
 {{ form.email }}
 {% if form.password.errors %}
    {% for error in form.password.errors %}
       <p>This field is required</p>
    {% endfor %}
 {% endif %}
 {{ form.password.label_tag }}
 {{ form.password }}
 {% if form.password1.errors %}
    {% for error in form.password1.errors %}
       <p>This field is required</p>
    {% endfor %}
 {% endif %}
 {{ form.password1.label_tag }}
 {{ form.password1 }}
 </form>

但是当我尝试注册用户时，我有错误

此字段是必填字段

表示password字段。我不明白为什么。

如果你帮助我，我会很高兴。

Answer 1

而不是print predefind错误消息尝试打印实际错误消息。

而不是

<p>This field is required</p>

使用

<p>{{ error }}</p>

Answer 2

在clean_password方法中，验证后返回password1。您应该返回密码对象。对于模型表格，这很重要。

保存模型时，表单字段名称用于决定哪个模型字段是哪个表单字段。

Django：密码字段“此字段是必填的”错误
