Django - clean_field（）没有被调用管理员内联表单的更新

我无法弄清楚为什么没有为在管理视图上更新的内联表单调用clean_field（）方法 . 我的代码似乎很简单（见下面的概要） .

当我通过管理界面（ http://admin/..../primary/1/ ）修改主表单时，如预期的那样，我看到：

• Admin.PrimaryAdminForm.clean_myfield（）调用

• Admin.PrimaryAdminForm.clean（）调用

• Model.Primary.clean（）调用

但是，当我修改主要内容时，在成员资格的管理员视图（ http://admin/..../membership/1/ ）中将其视为内联，我只看到：

• Model.Primary.clean（）调用

我尝试在以下位置放置“def clean_myfield（self）：”方法，但无法看到它从成员内联主要表单执行：

• Model.Primary.clean_myfield

• Admin.PrimaryAdmin.clean_myfield

• Admin.PrimaryAdminForm.clean_myfield

• Admin.PrimaryAdminInline.clean_myfield

还有其他地方应该放置这个clean_myfield代码吗？

我已经阅读（并重读）了[表格和字段验证] [docs.djangoproject.com/en/dev/ref/forms/validation/#form-and-field-validation]上的Django文档，它提供了很好的报道，但是内联验证没有任何内容 . 我还阅读了docs.djangoproject.com/en/dev/ref/contrib/admin/#adding-custom-validation-to-the-admin，但对内联特定验证没有帮助 . 还有其他文件吗？

---> Answered by Austin 提供了一个doc参考："If not specified"（见他的链接），这意味着答案 . 我在这个主题上添加了request to improve文档 .

经过进一步的实验，我通过将代码放入Model.Primary.clean（）方法找到了一种解决方法：

def clean(self):
    data = self.myfield
    data += "_extra" # not actual cleaning code 
    self.myfield = data

So the question remains ：为什么Model.clean（）似乎是唯一放置管理内联表单验证而不是clean_myfield（self）方法的地方？

---> Answered by Austin . 我需要将 form = PrimaryAdminForm 添加到PrimaryInline . 通过此添加，在成员资格表单上更新PrimaryInline myfield时，将调用PrimaryAdminForm.clean_myfield（self） . 由于添加了表单引用，代码排序已更新 .

Code synopsis:

没有forms.py文件 - 所有模型都通过管理界面更新

models.py：

class Membership(models.Model):
    name = models.CharField( max_length=NAME_LENGTH,
        null=True, blank=True, verbose_name="Membership Name Tag",
        help_text="Name of membership" )

class Primary(models.Model):
    user = models.OneToOneField(User, verbose_name="User Name")
    membership = models.OneToOneField(Membership, verbose_name="Membership Name")
    myfield = models.CharField("My Field", max_length=20, null=True, blank=True)


    # clean method altered as in Update comment 
    # Why must this be here? Why not in clean_myfield(self)
    def clean(self):
        data = self.myfield
        data += "_extra" # not actual cleaning code 
        self.myfield = data

admin.py：

class MembershipAdminForm(ModelForm):
    class Meta:
        model = Membership

class PrimaryAdminForm(ModelForm):
    class Meta:
        model = Primary

    def clean_myfield(self):
        data = self.cleaned_data['myfield']
        data += "_extra" # not actual cleaning code 
        return unicode(data)

    def clean(self):
        cleaned_data = super(PrimaryAdminForm, self).clean()
        # not actual cleaning code 
        return cleaned_data

# EDIT2: Moved PrimaryInline so it's defined after PrimaryAdminForm 
class PrimaryInline(admin.StackedInline):
    model = Primary
    form = PrimaryAdminForm   #EDIT2 as recommended by Austin
    raw_id_fields = ['user']
    verbose_name_plural = 'Primary Member'
    fieldsets = ((None, {'classes': ('mbship', ),
                         'fields': ('user', 'myfield')}), )

class MembershipAdmin(admin.ModelAdmin):
    form = MembershipAdminForm

    # inlines
    inlines = [PrimaryInline, ]

    fieldsets = ((None, {'classes': ('mbship',),
                         'fields': ('name'), }), )

class PrimaryAdmin(admin.ModelAdmin):
    form = PrimaryAdminForm
    list_display = ('__unicode__', 'user', 'status', 'date_used' )
    search_fields = ['user__first_name', 'user__last_name', 'user__email'] 

    fieldsets = ((None, {'classes': ('mbship',), 
                         'fields': ('user', 'membership', 'myfield'), }), )

    def clean_myfield(self):
        data = self.cleaned_data['myfield']
        data += "_extra" # not actual cleaning code 
        return unicode(data)
