我想改变formfield widget取决于其他域的值。默认选择是因为模型字段是外键。我的型号如下:Django管理内联表单动态改变charfield的选择域
class ProductFeatureValue(BaseName):
feature = models.ForeignKey('ProductTypeFeature')
class Meta:
verbose_name = _(u'Product Feature Value')
verbose_name_plural = _(u'Product Feature Values')
class ProductFeature(models.Model):
product = models.ForeignKey('Product')
feature = models.ForeignKey('ProductTypeFeature')
value = models.ForeignKey('ProductFeatureValue')
我的形式如下:
class ProductFeatureFormForInline(ModelForm):
class Meta:
model = ProductFeature
def __init__(self,*args,**kwargs):
super(ProductFeatureFormForInline,self).__init__(*args,**kwargs)
if isinstance(self.instance,ProductFeature):
try:
widget_type = self.instance.feature.product_type.producttypefeature_set.all()[0].widget #TODO Fix that 0 slice
if widget_type == u'TEXT':
self.fields['value'] = CharField(widget=TextInput())
if widget_type == u'MULTIPLE_SELECT':
self.fields['value'].widget = MultipleChoiceField()
except:
pass
它改变了场组件,但是,当它使它charfield与实例填充它,它显示了该模型的ID不是价值(作者:1),并且以这种方式展示它是有道理的,但我想展示(作者:Dan Brown)。 我尝试过初始值但不工作。任何提示,这将是高度赞赏。谢谢
