我剛開始學習Django,我有一個問題。如何覆蓋modelform類的save()方法並添加缺少的信息?
我試圖在保存表單數據時自動添加缺少的信息。我可以通過覆蓋modelform類的save()方法來更改/添加所需的「cleaned_data」信息,但是更改不會記錄在數據庫中。其實,如何編寫修改後的信息?這是代碼:
def save(self, commit = True, *args, **kwargs):
temp = ServiceMethods(url = self.cleaned_data.get('url'), wsdl_url = self.cleaned_data.get('wsdl_url'))
if not temp.get_wsdl_url():
temp.make_wsdl_url()
if temp.get_wsdl_url():
temp.make_wsdl()
self.cleaned_data['wsdl_url'] = temp.get_wsdl_url()
self.cleaned_data['wsdl_description'] = temp.get_wsdl_description()
super(ServiceForm, self).save(commit = commit, *args, **kwargs)
和型號:
class Services(models.Model):
name = models.CharField('Имя', max_length=256)
url = models.URLField('Ссылка', unique = True)
wsdl_url = models.URLField('Ссылка на WSDL-документ', blank=True)
description = models.TextField('Описание сервиса',blank=True)
wsdl_description = models.TextField('WSDL описание', blank=True, editable=False)
added = models.DateTimeField('Добавлено', auto_now_add=True)
TIA
是的,它的工作原理!非常感謝! – User 2010-12-20 21:16:14
