我想在模型django中进行多重选择及其结果(我使用了library),现在我尝试确保仅从模型字段中显示选择的项。表格,但我面临一个小问题:
AttributeError: 'MSFList' object has no attribute 'get_choices_selected'
1)我知道在该库中有一个函数get_choices_selected
返回选定的项目
2)我试图仅使用模型的输出,但是它返回字符串数据类型:((
我的模型。py
CHOSE_SIZE = (('XS', 'XS'),
('S', 'S'),
('M', 'M'),
('L', 'L'),
('XL', 'XL'),
('XXL', 'XXL'),
('XXXL', 'XXXL'))
.......
available_size = MultiSelectField(choices=CHOSE_SIZE, verbose_name='Available Sizes', default=None)
我的表格。py
class item_add_form(forms.Form):
quantity = forms.IntegerField(max_value=21, min_value=0)
size = forms.ChoiceField(widget=forms.RadioSelect, choices=CHOSE_SIZE)
def __init__(self, *args, **kwargs):
choices = kwargs.pop('choices', None)
super(item_add_form, self).__init__(*args, **kwargs)
self.fields['size'] = forms.ChoiceField(widget=forms.RadioSelect, choices=choices)
我的views.py
class MainPage(views.View):
products = Product.objects.get(ordered__gt=0)
form = item_add_form(choices =products.available_size.get_choices_selected())
contex = {'products' : products, 'form_input': form }
def get(self, request):
return render(request, 'MainPage/Mainpage.html', context=self.contex)
我将很高兴为您提供帮助,并向您提出建议:
1)是否可以以某种方式解决此问题?
2)或如何做得更好?
