Django 保存扩展用户模型的问题

我在提交一个表单时遇到了问题，该表单创建了一个从auth.user扩展而来的用户配置文件，该用户已经在Django Register注册

我收到错误：

请更正以下字段：

来自我模板中的一个代码字符串：

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

非常感谢您的帮助！如果有人能告诉我如何减少代码，我会觉得这太过分了。谢谢你的帮助：）

更新：

我知道是什么错误！我没有填写模型的用户字段。有谁能帮我减少代码的使用量吗

更新2：

表单现在已通过，但始终存在错误

使用此版本的my views.py时，我在/register/-accounts\u userprofile.first\u name处获取行

profile.save（）

的

我被传递到base_profile.html，其中只有名字和姓氏被填充为“添加/烫发添加/不添加/节食/中等/恐惧”字段。有人能帮忙吗？很抱歉成为这样一个noob>对于视图，您可以通过以下方式减少它：

else:
    form = RegistrationForm()
    context = {'form': form}
    return render_to_response('base_registration.html', context, context_instance=RequestContext(request))

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()

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

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

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

在这里，您将迭代字典并将所有键和值设置为profile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其他方法，例如：

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

profile.save()

此外，还应使用模型表格：

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

另外，django的用户模型已经有了名字和姓氏字段，因此您无需再次添加这些字段

我可以看到您的模型上也有很多字段，我建议您创建如下模型：

<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>

通过这种方式，您可以以更灵活的方式保存所有详细信息，而无需为用户保存大量字段。您可以让它变得更加有趣，并添加一个类型和一个函数来转换它（例如，如果您需要将值设置为整数）

因此，例如，您不必像
home\u num
或
diet
那样向
UserProfile
类添加字段，而可以执行以下操作：

<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>

然后只需访问任何：

print request.user.user_details_set.all()

它应该打印所有这些细节。从这种方法中我能看到的唯一一件坏事是，
ModelForms
不会那么容易工作，但我向您保证迁移会更加零星：）
您已经在“request.user”中找到了用户，为什么要再查一次？问题是我之前已经创建了这个用户，我不应该让他/她再输入用户名等。有什么解决方法吗？好的，刚刚更新了答案，问题是你正在做一个错误的查询，以获得用户@möter saidDo我仍然必须将用户字段添加到表单中？我仍然得到相同的错误，即用户字段是必需的>。哦，你应该在那里使用模型表单，你需要从元中排除该字段。只是更新一下
