Django get_absolute_url（將表單提交後返回到同一頁面）

Question

學習django。我有一個問題。 我已經完成了反饋表單，我需要在反饋表單確認後將用戶重定向到同一頁面。下面是代碼：

models.py

class Feedback(models.Model): 
     title = models.CharField(max_length=255) 
     text = models.TextField(max_length=5000) 
     user_name = models.CharField(max_length=255) 
     user_lastname = models.CharField(max_length=255) 
     email = models.EmailField(max_length=255) 
     send_time = models.DateTimeField(auto_now_add=True) 
     update_time = models.DateTimeField(auto_now=True) 

     def get_absolute_url(self): 
      return 

urls.py

url(r'^feedback$',views.FeedbackSendForm.as_view(), name='feedback'), 

views.py

class FeedbackSendForm(CreateView): 
     model = Feedback 
     fields = [ 
      'title', 
      'text', 
      'user_name', 
      'user_lastname', 
      'email', 
      ] 
     template_name = 'feedback.html' 

個feedback.html

<form method="post"> 
    {% csrf_token %} 
    {% for field in form %} 
     <span class="text-danger">{{ field.errors }}</span> 
     <div> 
      <label class="control-label">{{ field.label }}</label> 
      {{ field }} 
     </div> 
    {% endfor %} 
    <button type="submit">Submit</button> 
</form> 

任何想法？請幫忙。 預先感謝您

Answer 1

如果你想覆蓋get_absolute_url您的機型，下面的代碼可以幫助你：

from django.urls import reverse 


class Feedback(models.Model): 
    # the model fields 

    def get_absolute_url(self): 
     # reverse expects the view name 
     return reverse('feedback') 

任何Feedback對象的絕對URL將是視圖FeedbackSendForm。這通過將視圖名稱feedback傳遞到reverse來指定。

這就是你需要的嗎？

例CreateView的：

views.py：

class FeedbackSendForm(CreateView): 
     model = Feedback 
     fields = ['title','text','user_name','user_lastname','email',] 
     template_name = 'feedback.html' 
     form_class = form_name 

     def form_valid(self, form): 
      """ 
      If the form is valid, redirect to the supplied URL. 
      """ 
      return HttpResponseRedirect(self.get_success_url()) 
      """ 
      define `get_success_url' to your model or use `get_absolute_url` instead. 

希望這有助於。
