Django表单 - 附加到类的meta排除和小部件 [英] Django forms - append to class meta exclude and widgets
本文介绍了Django表单 - 附加到类的meta排除和小部件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
是否可以附加到继承的表单的排除或小部件变量?
我到目前为止设置了以下设置。
class AddPropertyForm(forms.ModelForm):
pre>
num_months = forms.ChoiceField(choices = MONTHS)
request_featured = forms.BooleanField(required = False)
featured_months = forms.ChoiceField(choices = MONTHS)
class Meta():
model = RentalProperty
exclude =('listing_id','active_listing ','active_listing_expiry_date','featured_property','featured_expiry_date','slug','property_manager')
widgets = {
'property_type':forms.Select(attrs = {'onchange':'propertyType ()'}),
}
class EditPropertyForm(AddPropertyForm):
request_reactivation = forms.BooleanField(required = False)
class Meta(AddPropertyForm.Meta) :
exclude =('address1','property_type')
widgets = {
'request_reactivation':forms.CheckboxInput(attrs {'onchange':'reactivateProperty()'}),
}
我试图让EditPropertyForm的最终结果看起来像排除和小部件语句一样。
exclude =('address1','property_type','listing_id','active_listing','active_listing_expiry_date','featured_property','featured_expiry_date','slug','property_manager' )
widgets = {
'request_reactivation':forms.CheckboxInput(attrs {'onchange':'reactivateProperty()'}),
'property_type':forms.Select attrs = {'onchange':'propertyType()'}),
}
如果有一个更好的方法,请建议。
非常感谢任何帮助。
解决方案从t获取属性怎么样?他的父母Meta类和更新他们?
这样的东西(未经测试):
class Meta(AddPropertyForm.Meta):
exclude = tuple(list(AddPropertyForm.Meta.exclude)+ ['address1','property_type'])
widgets = AddPropertyForm.Meta.widgets .copy()
widgets.update({
'request_reactivation':forms.CheckboxInput(attrs {'onchange':'reactivateProperty()'}),
})
它不漂亮,但应该让你想要的。
Is it possible to append to the exclude or widgets variables of an inherited Form?
I have the following set up so far.
class AddPropertyForm(forms.ModelForm): num_months = forms.ChoiceField(choices=MONTHS) request_featured = forms.BooleanField(required=False) featured_months = forms.ChoiceField(choices=MONTHS) class Meta(): model = RentalProperty exclude = ('listing_id', 'active_listing', 'active_listing_expiry_date', 'featured_property', 'featured_expiry_date', 'slug', 'property_manager') widgets = { 'property_type': forms.Select(attrs={'onchange':'propertyType()'}), } class EditPropertyForm(AddPropertyForm): request_reactivation = forms.BooleanField(required=False) class Meta(AddPropertyForm.Meta): exclude = ('address1', 'property_type') widgets = { 'request_reactivation': forms.CheckboxInput(attrs {'onchange':'reactivateProperty()'}), }
I am trying to get the end result for EditPropertyForm to look like the following for the exclude and widgets statements.
exclude = ('address1', 'property_type', 'listing_id', 'active_listing', 'active_listing_expiry_date', 'featured_property', 'featured_expiry_date', 'slug', 'property_manager') widgets = { 'request_reactivation': forms.CheckboxInput(attrs {'onchange':'reactivateProperty()'}), 'property_type': forms.Select(attrs={'onchange':'propertyType()'}), }
If there is a better approach, please suggest.
Any help is most appreciated.
解决方案What about grabbing the properties from the parent Meta class and updating them?
Something like this (untested):
class Meta(AddPropertyForm.Meta): exclude = tuple(list(AddPropertyForm.Meta.exclude) + ['address1', 'property_type']) widgets = AddPropertyForm.Meta.widgets.copy() widgets.update({ 'request_reactivation': forms.CheckboxInput(attrs {'onchange':'reactivateProperty()'}), })
It's not pretty, but should get you what you want.
