Python Django-无法更新表单

我的模板在一个表单中有三列，它们分别工作。若我给联系人栏和男性栏输入，它将保存在我的数据库中。 所以基本上我只想更新男性作为联系人，男性和女性输入以相同的html形式出现。 我可以更新触点，但不包括公输入或母输入。 他们都在同一个页面。我想让他们分开工作，这样我可以更新他们

问题是，当我为项目提供输入时，它会被发布，而不是男性和女性的输入。 即使我在forms.py中包含了male类的contact1，表单也不会被提交

from django.urls import path , include
from  . import views



urlpatterns = [
    path('', views.index, name='index'),
    path('info/', views.info, name='info'),
    path('features/', views.features, name='features'),
    path('add/', views.add, name='add'),
    path('add/' ,views.success, name='success'),
    path('update/<str:pk_test>/' ,views.update, name='update')
   

]

models.py

class Male(models.Model):
    contact1 = models.ForeignKey(Contact,  on_delete=models.CASCADE,null=True)
    chest = models.CharField(max_length=30 , blank=True)
    neck = models.CharField(max_length=30 , blank=True)
    full_shoulder_width = models.CharField(max_length=30 , blank=True)
    right_sleeve = models.CharField(max_length=30 , blank=True)
    left_sleeve = models.CharField(max_length=30 , blank=True)
    bicep = models.CharField(max_length=30 , blank=True)
    def __str__(self):
        return chest

 

add.py

def add(request):
    template_name = 'add.html'
    c_form = commentForm()
    m_form = maleForm()   
    f_form = femaleForm()
                    

   
    contact = Contact.objects.all()  
    if request.method =='POST':
        c_form = commentForm(request.POST)
        m_form = maleForm(request.POST)
        f_form = femaleForm(request.POST)
        if c_form.is_valid() and (m_form.is_valid() or f_form.is_valid()):
                gender = c_form.cleaned_data.get('gender')
                username= c_form.cleaned_data.get('name')
                contact = c_form.save()     
                
                if gender == 'female':
                       
                        female = f_form.save(commit=False)
                        female.contact2 = contact
                        female.save()
                        messages.success(request, f"Form Submitted: {username}")
                        return redirect("success")
                else:
                        male = m_form.save(commit=False)
                        male.contact1 = contact
                        male.save()
                       
                        messages.success(request, f"Form Submitted: {username}")
                        return redirect("success")     
        else:     
                    c_form = commentForm()
                    m_form = maleForm()   

请先检查一下我刚才做的这个项目，它可以帮助您很多： --转到项目树内的帖子

在这里，我将举一个简单的例子来说明它是如何工作的：

class Update_Posts(UpdateView):
    form_class = Form_Change
    model = MyPosts
    template_name = 'form_page.html'

    # Define a post method
    def post(self, request, pk):
        if self.request.user.admin_user or self.request.user.staff_user or self.request.user.active_user:
            instance = get_object_or_404(MyPosts, pk=pk)
            form = self.form_class(
                self.request.POST, self.request.FILES or None, instance=instance)
            if form.is_valid():
                return self.form_valid(form)
            else:
                print('this data isn\'t Valid')

我是在基于函数的视图中练习的，所以我现在想在基于类的视图中练习。最好先练习基本功，祝你好运

Hay there k, 
Since You are working with Django , there is a built in Function called (UpdateView), 

class Update_Posts(UpdateView):
    form_class = Form_Change
    model = MyPosts
    template_name = 'form_page.html'

    # Define a post method
    def post(self, request, pk):
        if self.request.user.admin_user or self.request.user.staff_user or self.request.user.active_user:
            instance = get_object_or_404(MyPosts, pk=pk)
            form = self.form_class(
                self.request.POST, self.request.FILES or None, instance=instance)
            if form.is_valid():
                return self.form_valid(form)
            else:
                print('this data isn\'t Valid')
