我已经为模态表单创建了一个FBV（弹出窗口），我希望拥有相同的视图来处理创建和更新，我使用FBV的原因是通过查询分配外键，而不是通过URL传递ID。 。请注意，JS脚本正在用来调用Modal并在其中渲染表单。
**Models.py:**
class Startup ( models.Model ) :
author = models.OneToOneField ( User , on_delete = models.CASCADE )
startup_name = models.CharField ( 'Startup Name' , max_length = 32 , null = False , blank = False )
class Startup_About ( models.Model ) :
str_about = models.OneToOneField ( Startup , on_delete = models.CASCADE )
about = models.TextField ( 'About Startup' , max_length = 2000 , null = False , blank = False )
problem = models.TextField ( 'Problem/Opportunity' , max_length = 2000 , null = False , blank = False )
business_model = models.TextField ( 'Business Monitization Model' , max_length = 2000 , null = False ,blank = False )
offer = models.TextField ( 'Offer to Investors' , max_length = 2000 , null = False , blank = False )
def __str__(self) :
return str(self.str_about)
**forms.py:**
class startupform(forms.ModelForm):
class Meta:
model = Startup
fields = ('startup_name',)
widgets = {
'startup_name': forms.TextInput(attrs = {'class':'form-control'}),
}
def clean(self):
super ( ).clean ( )
startup_name = self.cleaned_data.get ( 'startup_name' )
startup_qs = Startup.objects.filter ( startup_name = startup_name )
if startup_qs.exists ( ):
raise forms.ValidationError ( 'This Startup Already Exist!' )
class startupaboutform(forms.ModelForm):
class Meta:
model = Startup_About
fields = ('about','problem','business_model','offer',)
widgets = {
'about' : forms.Textarea ( attrs = { 'class' : 'form-control' } ) ,
'problem' : forms.Textarea ( attrs = { 'class' : 'form-control' } ) ,
'business_model' : forms.Textarea ( attrs = { 'class' : 'form-control' } ) ,
'offer' : forms.Textarea ( attrs = { 'class' : 'form-control' } ) ,
}
**Views.py:**
@login_required
@str_required
def create_startupform(request):
q = Startup.objects.filter(author=request.user)
if q.exists():
return redirect ( 'appwizard')
else:
form = startupform ( request.POST or None )
if form.is_valid ( ) :
instance = form.save (commit = False)
instance.author = request.user
instance.save()
return redirect ( 'appwizard', pk = instance.pk )
else:
form = startupform()
return render ( request , 'str_name.html' , { 'form' : form } )
decorators = [str_required, login_required]
@method_decorator(login_required, name='dispatch')
@method_decorator(str_required, name='dispatch')
class aboutview(FormView):
template_name = 'create_about.html'
form_class = startupaboutform
@login_required
@str_required
def create_startupaboutform(request) :
q = Startup.objects.filter ( author = request.user )[0]
R = get_object_or_404(Startup, startup_name=q)
if request.method == 'POST':
form = startupaboutform ( request.POST )
stup = Startup_About.objects.get_or_create(str_about=R )[0]
if form.is_valid ( ) :
instance = form.save ( commit = False )
instance.str_about = R
instance.save ( )
return redirect('/appwizard/')
else :
form = startupaboutform ()
return render ( request , 'create_about.html' , { 'form' : form } )
**urls.py:**
urlpatterns = [
path ( 'appwizard/' , views.applicationwizard , name = 'appwizard' ) ,
path('create_startupaboutform/', views.create_startupaboutform, name='create_startupaboutform'),
path ( 'aboutview/' , views.aboutview.as_view() , name = 'aboutview' ) ,
]
**Template - appwizard:**

**Template - creaye_about - form in a Modal:**

您的clean方法应返回已清除的数据，因此：
