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,正如预期的那样,我看到:
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:
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中执行:
是否应该在其他地方放置这个clean_myfield代码?
我已经[形式和字段验证] [docs.djangoproject.com/en/dev/ref/forms/validation/#form-and-field-validation]阅读(并重读)了Django文档。覆盖范围,但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?
---> Austin回答提供了一个文档参考:“如果没有指定”(请参阅他的链接),这意味着答案。我在这个主题上添加了request to improve个文档。
在进一步试验后,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
所以问题仍然存在: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?
---> Austin回答。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。
代码简介:
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)
答案 0 :(得分:8)
验证发生在ModelForm
个对象上,而不是ModelAdmin
个对象上。如果要覆盖任何干净的方法,则必须为每个所需的模型创建自己的ModelForm
后代。
在您的示例中,PrimaryInline
类未指定form
。 If not specified,使用的表单为ModelForm
,没有任何自定义清理方法。
试试这个:
class PrimaryInline(admin.StackedInline):
# ... existing code ...
form = PrimaryAdminForm
现在,您将使用自定义PrimaryAdminForm
和相关的clean()
方法。
