在用户向 Django-Register 注册后，我在提交创建从 auth.User 扩展的用户配置文件的表单时遇到问题。

我收到错误消息：Please correct the following fields:来自模板中的一串代码：

{% if form.errors %}<p>Please correct the following fields:</p>{% endif %}

这告诉我表单中是否有错误，其余的表单模板如下所示：

<div class='register_div'>
  {% if form.first_name.errors %}
    <p class='error'>{{ form.first_name.errors }}</p>
  {% endif %}
  <p>
    <label for='first_name'{% if form.first_name.errors %}class='error'{% endif %}>
      First Name:
    </label>
  </p>
  <p>{{ form.first_name }}</p>
</div>

任何帮助深表感谢！如果有人能告诉我如何减少代码以及我发现过多的代码，那就太好了。感谢你的帮助 ：）

更新：

我知道错误是什么！参考这个！我没有填写模型的用户字段。谁能帮我解决这个问题并减少我使用的代码量？

更新 2：

表格现在通过了，但总是有错误。

当我使用这个版本的views.py时，我得到IntegrityError at /register/ - accounts_userprofile.first_name may not be NULL了这条线profile.save()

`if form.is_valid():
        user = User.objects.get(username=request.user)

如果我改用这个版本的views.py：

if form.is_valid():
        profile = User.objects.get(username=request.user)

        for key in UserProfileForm.base_fields.keys():
            for val in form.cleaned_data.values():

        profile.save()

        return render_to_response('base_profile.html', context_instance=RequestContext(request))`

我被传递给 base_profile.html，只有 first_name 和 last_name 填充了 term_add/perm_add/nok_add/diet/med_cond/fears 字段。任何人都可以帮忙吗？对不起，我是个菜鸟>.<

我用于一次注册 User 和 UserProfile 的旧 views.py 看起来像这样：

对于视图，您可以通过以下方式减少它：

if form.is_valid():
    profile = UserProfile(user=request.user)  # you already have the user in the request.

    for key, val in form.cleaned_data.values():
        setattr(profile, key, val)

    profile.save()

在这里，您将遍历字典并将所有键和值设置为配置文件对象。请检查是否需要所有密钥，如果不需要，您将不得不以某种方式删除它们或尝试不同的方法，例如：

my_keys = ('key1', 'key2', 'key3', ...)
for key in my_keys:
    profile[key] = form.cleaned_data.get(key, "")

profile.save()

你也应该使用模型形式：

class RegistrationForm(forms.ModelForm):
    class Meta:
        model = UserProfile
        exclude = ('user',)

此外，来自 django 的用户模型已经有一个 first_name、last_name 字段，因此您无需再次添加这些字段。

我可以看到你的模型上也有很多字段，我建议你创建一个这样的模型：

class UserDetails(models.Model):
    user = models.ForeignKey(User)        

    name = models.CharField(max_length=255)
    value = models.CharField(max_length=255)

这样，您可以以更灵活的方式保存所有详细信息等，而不是为用户提供大量字段。你可以让它变得更有趣，并添加一个类型和一个函数来转换它（例如，如果你需要这个值是一个整数）。

因此，例如，不要向UserProfile类中添加字段，home_num或者diet 您可以执行以下操作：

for key, value in form.cleaned_data.values():
    UserDetails(user=request.user, name=key, value=value).save()

然后访问任何：

print request.user.user_details_set.all()

它应该打印所有这些细节。我可以从这种方法中看到的唯一不好的事情是它ModelForms不会那么容易工作，但我向你保证迁移会更加零星:)
