Python常见问题
我想从表格中输入的数据来检查这个人是否存在于数据库中，如果是的话，我们将把登记表跳转到另一个表格中。唉，我的代码不起作用。有人能帮我
表格：
FORMS = [
("stage1-1", RegisterIdentification),
("stage1-2", RecRegister),
("stage2-1", BirthIdentification),
("stage2-2", RecBirth),
("stage3-1", FatherIdentification),
("stage3-2", RecFather),
("stage4-1", MotherIdentification),
("stage4-2", RecMother),
]模板
TEMPLATES = {
"stage1-1": "fr/public/births-wizard/stage1-1.html",
"stage1-2": "fr/public/births-wizard/stage1-2.html",
"stage2-1": "fr/public/births-wizard/stage2-1.html",
"stage2-2": "fr/public/births-wizard/stage2-2.html",
"stage3-1": "fr/public/births-wizard/stage3-1.html",
"stage3-2": "fr/public/births-wizard/stage3-2.html",
"stage4-1": "fr/public/births-wizard/stage4-1.html",
"stage4-2": "fr/public/births-wizard/stage4-2.html",
}视图：
class BirthsWizard(SessionWizardView):
instance = None
def get_form(self, step=None, data=None, files=None):
"""
change the form or the step instance dynamically from the data we entered
at the previous step
"""
# get the default form
form = super(BirthsWizard, self).get_form(step, data, files)
if step is None:
step = self.steps.current
if step == 'stage1-2':
# get prev datas and chek if they are in Database
step1_data = self.get_cleaned_data_for_step('stage1-1')
register_doctype = step1_data.get('registerDoctype')
register_nationality = step1_data.get('registerNationality')
register_idNum = step1_data.get('registeridNum')
if register_doctype and register_nationality and register_idNum:
check_register = BirthsDeclarer.objects.filter(doctype=register_doctype,
nationality=register_nationality,
idNum=register_idNum)
if check_register:
# if prev datas are in Database jump to a specific step
form_name = "stage2-1"
form = form_name
return form
def get_template_names(self):
return TEMPLATES[self.steps.current]
@method_decorator(login_required)
def dispatch(self, *args, **kwargs):
return super(BirthsWizard, self).dispatch(*args, **kwargs)
def done(self, form_list, **kwargs):
# i will process data here
return render(self.request, 'fr/public/births-wizard/done.html', {'form_data': [ form.cleaned_data for form in form_list ] })Result: the page displays without the form结果：页面显示时没有窗体
