我的WizardView
流程ModelForm
有两步。我不明白为什么,当我第二步时,django告诉我需要以前的字段。我尝试在这样的步骤之间发送数据:
forms.py
class RequestForm1(forms.ModelForm):
class Meta:
model = Product
fields = ('title', 'product_class', )
class RequestForm2(forms.ModelForm):
class Meta:
model = Product
fields = ( 'dimension_x', )
views.py
class RequestView(SessionWizardView):
instance = None
def get_template_names(self):
return [TEMPLATES[self.steps.current]]
def get_form_initial(self, step):
current_step = self.storage.current_step
if current_step == 'step2':
prev_data = self.storage.get_step_data('step1')
print(prev_data)
title = prev_data.get('step1-title', '')
product_class = prev_data.get('step1-product_class', '')
return self.initial_dict.get(step, {
'title': title,
'product_class': product_class
})
return self.initial_dict.get(step, {})
def done( self, form_list, **kwargs ):
self.instance.save()
return HttpResponseRedirect('/catalogue/request/')
答案 0 :(得分:0)
请在下面找到我的解决方案
forms.py
class RequestForm1(forms.ModelForm):
class Meta:
model = Product
fields = ('title', 'product_class', )
class RequestForm2(forms.ModelForm):
class Meta:
model = Product
fields = ( 'title', 'product_class', 'dimension_x', )
widgets = {
'title': forms.HiddenInput(),
'product_class': forms.HiddenInput()
}
views.py
class RequestView(SessionWizardView):
instance = None
def get_template_names(self):
return [TEMPLATES[self.steps.current]]
def get_form_instance( self, step ):
if self.instance is None:
self.instance = Product()
return self.instance
def get_form(self, step=None, data=None, files=None):
form = super(RequestView, self).get_form(step, data, files)
if step == 'step2':
prev_data = self.storage.get_step_data('step1')
title = prev_data.get('step1-title', '')
product_class = prev_data.get('step1-product_class', '')
form.fields['title'].initial = title
form.fields['product_class'].initial = product_class
return form
def done(self, form_list, **kwargs):
self.instance.save()
return HttpResponseRedirect('/catalogue/request/success')
