formfield_for_choice_fieldのキーエラーを無効にする

Question

私は何も変更しなくても、インラインadminのキーを投げてformfield_for_choice_fieldを無効にしますか？

ProfileInline：

class ProfileInline(admin.StackedInline): 
    model = Profile 
    can_delete = False 
    classes = ['collapse', ] 
    form = ProfileForm 
    readonly_fields = ('thumbnail_img',) 
    extra = 1 
    max_num = 1 
    min_num = 1 
    fieldsets = (
     (None, { 
      'fields': (
       'thumbnail_img', 'avatar', 'nickname', 'gender', 
       'phone_number', 'birth_place', 'birth_date', 'angkatan', 
       'year_registered', 'year_graduation', 'religion', 'jobs' 
      ) 
     }), 
     ('Alamat saat sekolah di sman 3 Padang', { 
      'fields': ('old_address',) 
     }), 
     ('Alamat sekarang', { 
      'fields': ('curr_country', 'curr_province', 
        'curr_city', 'curr_street') 
     }), 
     ('Media Sosial', { 
      'fields': ('link_facebook', 'link_twitter', 'link_instagram', 
        'link_whatsup', 'link_bbm') 
     }), 
     ('Sembunyikan Data Pribadi', { 
      'fields': ('show_phone', 'show_curr_address', 'show_jobs', 
        'show_social_link', 'show_family') 
     }) 
    ) 

    def formfield_for_choice_field(self, db_field, request, **kwargs): 
     super(ProfileInline, self).formfield_for_choice_field(db_field, request, **kwargs)

フィールドセットをインラインから削除しようとしましたが、エラーは発生しません。フィールドセットが原因ですか？

トレースバックを振り返ると、見つからなかったキーは選択肢を使用しているフィールドであることがわかりました。

class Profile(models.Model): 
    GENDER_CHOICES = choices.GENDER_CHOICES 
    RELIGION_CHOICES = choices.RELIGION_CHOICES 
    ANGKATAN_CHOICES = choices.ANGKATAN_CHOICES 
    YEAR_REGISTERED_CHOICES = choices.YEAR_REGISTERED_CHOICES 
    YEAR_GRADUATION_CHOICES = choices.YEAR_GRADUATION_CHOICES 

    gender = models.CharField(
     verbose_name="jenis kelamin", 
     max_length=1, 
     choices=GENDER_CHOICES 
    ) 
    angkatan = models.PositiveIntegerField(
     verbose_name="angkatan", 
     choices=ANGKATAN_CHOICES, 
     help_text="Angkatan di Sman 3 Padang." 
    ) 
    year_registered = models.PositiveIntegerField(
     verbose_name="tahun masuk", 
     choices=YEAR_REGISTERED_CHOICES, 
     help_text="Tahun masuk di Sman 3 Padang." 
    ) 
    year_graduation = models.PositiveIntegerField(
     verbose_name="tahun lulus", 
     choices=YEAR_GRADUATION_CHOICES, 
     help_text="Tahun lulus dari Sman 3 Padang." 
    ) 
    religion = models.PositiveIntegerField(
     verbose_name="agama", 
     choices=RELIGION_CHOICES 
    ) 

これらの5つのフィールドがProfileFormで発見されていない。ここで

は私のモデルのサブセットです。

このためハックのが見つかりました並べ替え、formfield_for_choice_fieldでスーパーを呼び出し、django.contrib.admin.options.BaseModelAdminクラスで見つかったベースの実装を使用していないことによって：

def formfield_for_choice_field(self, db_field, request, **kwargs): 
    # super(ProfileInline, self).formfield_for_choice_field(db_field, request, **kwargs) 
    if db_field.name == "angkatan" and not request.user.is_superuser: 
     kwargs['choices'] = (
      (request.user.admin.angkatan, str(request.user.admin.angkatan)), 
     ) 

    # Base implementation bellow 
    if db_field.name in self.radio_fields: 
     # Avoid stomping on custom widget/choices arguments. 
     if 'widget' not in kwargs: 
      kwargs['widget'] = widgets.AdminRadioSelect(attrs={ 
       'class': get_ul_class(self.radio_fields[db_field.name]), 
      }) 
     if 'choices' not in kwargs: 
      kwargs['choices'] = db_field.get_choices(
       include_blank=db_field.blank, 
       blank_choice=[('', _('None'))] 
      ) 
    return db_field.formfield(**kwargs) 

Answer 1

formfield_for_choice_fieldオーバーライドが何かを返す必要があります。

def formfield_for_choice_field(self, db_field, request, **kwargs): 
    if db_field.name == "some_field": 
     # do stuff 
    return super(ProfileInline, self).formfield_for_choice_field(db_field, request, **kwargs) 

あなたべき意識し、またformfield_for_choice_field説明以下note：あなたはそれをこのように書く必要があります。詳細はhereで説明します。
