在多個模板中顯示相同的表格

Question

我有一個表單需要在兩個不同的模板中顯示。一個是主頁，即在邀請頁面上顯示只有邀請表格和另一個在主頁上。當從主頁填寫表格時，如果有錯誤，應從該表格的主頁面（即邀請模板）顯示錯誤。

我可以在邀請模板中顯示錶單並且錯誤顯示工作正常，但是如果我從主頁填寫表單，即使我傳遞正確的值，我總是會得到'該字段是必需的'錯誤。

這裏是我的代碼

def requestInvitation(request): 
    form = InviteForm(request.POST or None) 
    if form.is_valid(): 
     join = form.save(commit=False) 
     email = form.cleaned_data.get('email') 
     already_join, created = Invitation.objects.get_or_create(email=email) 
     if created: 
      already_join.invite_code = get_invite_code() 
      already_join.save() 
      send_request_received_email.delay(email,already_join.email_tracker) 
      messages.success(request, "Thank you for your interest.") 
     return HttpResponseRedirect('/') 
    context = {"form": form} 
    return render(request, 'invitation/invitation.html', context) 


def index(request): 
    form = InviteForm(request.POST or None) 
    context = {"form": form} 
    if not request.user.is_authenticated(): 
     return render(request, "home.html", context) 
    else: 
     return render(request, "home.html", context) 


url(r'^request/$', requestInvitation, name='request-invitation'), 

UPDATE

def index(request): 
    form = InviteForm(request.POST or None) 
    if form.is_valid(): 
     join = form.save(commit=False) 
     print ('noin', join) 
     email = form.cleaned_data.get('email') 
     already_join, created = Invitation.objects.get_or_create(email=email) 
     print ('already_join', already_join, created) 
     if created: 
      already_join.invite_code = get_invite_code() 
      already_join.save() 
      send_request_received_email.delay(email,already_join.email_tracker) 
      messages.success(request, "Thank you for your interest") 
      return HttpResponseRedirect('/') 
     else: 
      return HttpResponseRedirect('/invitations/request') 
    # return HttpResponseRedirect('/invitations/request') 
    context = {"form": form} 
    return render(request, 'index.html', context) 

我改變了我的索引視圖來此。如果我填寫正確的值，數據將被保存，但如果有錯誤，它不會重定向到/邀請/請求頁面以顯示該錯誤。如果我在form.is_invalid（）的else條件中使用HttpResponseRedirect，那麼當我進入主頁時，我會立即重定向到/ invitation/request頁面。

您還沒有驗證和保存在您的主頁視圖的形式，所以基本上它仍然是空
