我有一个看起来像这样的表单 - 一个有下拉选择的表单:
class ContactUs(forms.Form):
TYPES = (
('hi', 'Say Hi'),
('restaurant', 'Introducing a Restaurant'),
('event', 'An Event is coming up'),
('promotion', 'Interesting Promotion'),
)
subject = forms.ChoiceField(choices=TYPES)
我想从request.GET.get('subject')
读取,以便我可以动态选择
所以它看起来像这样:
subject = forms.ChoiceField(choices=TYPES, initial=request.GET.get('subject'))
显然,选择是:嗨,餐厅,活动或促销,网址看起来像这样:
http://localhost:8000/contact?subject=promotion
问题是我不能做request.GET.get('subject')
我们如何解决这个问题?
答案 0 :(得分:2)
contact_us = ContactUs(initial={'subject': request.GET.get('subject')})
