django - 拡張ユーザーモデルの保存に関する問題

Question

ユーザーがDjango-Registerに登録された後、auth.Userから拡張されたユーザープロファイルを作成するフォームを送信する際に問題が発生しました。

エラーが表示されます:Please correct the following fields:テンプレート内のコードの文字列から:

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

フォームにエラーがあるかどうかがわかります。残りのフォームテンプレートは次のようになります。

<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>

私はエラーが何であるか知っています！これを参照してください！モデルのユーザーフィールドに入力しませんでした。誰でもそれを手伝って、使用するコードの量を減らすことができますか?

フォームは渡されるようになりましたが、常にエラーが発生します。

このバージョンの views.py を使用するIntegrityError at /register/ - accounts_userprofile.first_name may not be NULLと、行が表示されますprofile.save()

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

代わりにこのバージョンの views.py を使用すると:

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))`

base_profile.html に渡され、first_name と last_name だけが term_add/perm_add/nok_add/diet/med_cond/fears フィールドのいずれかで埋められます。誰でも助けることができますか？初心者でごめんなさい >.<

User と UserProfile を一度に登録するために使用された私の古い views.py は、次のようになりました。

ビューの場合、次のようにして減らすことができます：

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()

ここでは、ディクショナリを繰り返し処理し、すべてのキーと値をプロファイルオブジェクトに設定しています。すべてのキーが必要であることを確認してください。そうでない場合は、何らかの方法でそれらを削除するか、別のアプローチを試す必要があります。たとえば、次のようになります。

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

profile.save()

また、モデルフォームを使用する必要があります。

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

また、django のユーザーモデルには既に first_name、last_name フィールドがあるため、それらを再度追加する必要はありません。

モデルには多くのフィールドもあることがわかります。次のようなモデルを作成することをお勧めします。

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

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

このようにして、ユーザーに膨大な量のフィールドを用意する代わりに、すべての詳細などをより柔軟な方法で保存できます。もっと面白くして、変換する型と関数を追加できます (たとえば、値を整数にする必要がある場合)。

たとえば、次のようにUserProfileクラスにフィールドを追加する代わりに、次のようhome_numなdiet ことを行うことができます。

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

そして、次のいずれかにアクセスします。

print request.user.user_details_set.all()

そして、これらすべての詳細を出力する必要があります。このアプローチから私が見ることができる唯一の悪い点は、ModelFormsそれほど簡単に機能しないことですが、移行がより散発的であることを保証します:)
