Django窗體在POST後不顯示

Question

在下面的示例中，我試圖獲取所有要在模板中顯示的錯誤消息。我已經嘗試了所有論壇中提到的幾乎所有內容。以下是我的代碼。請告訴我，我錯過了什麼

表

class RegistrationForm(UserCreationForm): 
    email = forms.EmailField(required=True) 

    class Meta: 
     model = User 
     fields = (
      'username', 
      'first_name', 
      'last_name', 
      'email', 
      'password1', 
      'password2' 
     ) 

     def save(self, commit=True): 
      user = super(RegistrationForm, self).save(commit=False) 
      user.first_name = self.cleaned_data['first_name'] 
      user.last_name = self.cleaned_data['last_name'] 
      user.email = self.cleaned_data['email'] 

      if commit: 
       user.save() 

      return user 

查看

def register (request): 
    print(request.method) 
    if request.method == 'POST': 
     form = RegistrationForm(request.POST) 
     if form.is_valid(): 
      form.save() 
      print("Saved") 
      return render(request, 'main/product.html',{}) 
     else: 
      print("Some Error", form.errors) 
      args = {'form':form,'carousel':'display:none'}  
      print(args['form']) 
      return render(request, 'accounts/register.html',args) 
     # if a GET (or any other method) we'll create a blank form 
    else: 
     form = RegistrationForm() 

    args = {'form':form,'carousel':'display:none'} 
    return render(request, 'accounts/register.html',args) 

HTML模板

<form id="register" method="post" action="{% url 'register' %}"> 
    {% csrf_token %} 
    <div class="form-register-with-email"> 
    <div class="form-white-background"> 
    <div class="form-title-row"> 
     <h1>Create an account</h1> 
    </div> 
    {{ form.errors }} 
    {% for field in form %} 
    <div class="form-row"> 
     <label> 
     <span>{{field.label}}</span> 
     {{ field }} 
     </label> 
    </div> 
    {% endfor %} 

    <div class="form-row"> 
     <button type="submit">Register</button> 
    </div> 
    </div> 
    </div> 
</form> 

在我按下submit之後觸發視圖，當我在render語句之前打印時，表單顯示所有錯誤信息。但提交後，渲染實際上並未觸發屏幕上的任何更改。

下面是印刷中的django輸出。

我在想什麼？

Answer 1

做這樣的

print(request.method) 
if request.method == 'POST': 
    form = RegistrationForm(request.POST) 
    if form.is_valid(): 
     form.save() 
     print("Saved") 
     return render(request, 'main/product.html',{}) 
else: 
    form = RegistrationForm() 
    args = {'form':form,'carousel':'display:none'} 
    return render(request, 'accounts/register.html',args)

解決了這個問題。這是我的JavaScript文件中的一箇舊代碼，導致了這個問題。一旦這個問題得到解決，表單就會正確提交
