Django - 表單提交沒有重定向

我在我的繩索盡頭弄清楚爲什麼一個簡單的表單重定向不起作用。我通過POST請求提交了一個帶有一個文本字段的表單，該表單與相同views.py文件中某個函數的某些數據組合在一起，然後將其保存到數據庫的模型中。出於某種原因，通過我在提交表單時設置的重定向方案，我得到了表單的第二個副本。Django - 表單提交沒有重定向

feedbackapp/views.py

from django.shortcuts import render, redirect 
from django.http import HttpResponseRedirect 
from django.urls import reverse 

from .forms import FeedbackForm 
from .models import Feedback 


def record_feedback(request): 
    if request.method == 'POST': 
     form = FeedbackForm(request.POST) 
     if form.is_valid(): 
      feedback = Feedback() 
      feedback.submitter_ip = get_client_ip(request) 
      feedback.feedback_text = form.cleaned_data['feedback'] 
      feedback.save() 
      return HttpResponseRedirect(reverse('feedbackapp:thanks')) 

    elif request.method == 'GET': 
     form = FeedbackForm() 
     return render(request, 'feedbackapp/feedback_form.html', {'form': form}) 


def thanks(request): 
    return render(template_name='feedbackapp/thanks.html',request=request) 


# https://stackoverflow.com/questions/4581789/how-do-i-get-user-ip-address-in-django 
def get_client_ip(request): 
    x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR') 
    if x_forwarded_for: 
     ip = x_forwarded_for.split(',')[-1] # needs to be the last element in array for Heroku 
    else: 
     ip = request.META.get('REMOTE_ADDR') 
    return ip

feedbackapp/forms.py

from django import forms 


class FeedbackForm(forms.Form): 
    feedback = forms.CharField(label='Feedback', max_length=5000)

feedbackapp/templates/feedbackapp/feedback_form.html

<!DOCTYPE html> 
<html lang="en"> 
<head> 
    <meta charset="UTF-8"> 
    <title>Anonymous Feedback</title> 
</head> 
<body> 
    <form action="/" method="post"> 
     {% csrf_token %} 
     {{ form }} 
     <input type="submit" value="Submit"/> 
    </form> 
    <p><i>Note: IP addresses are collected with each submission.</i></p> 
</body> 
</html>

feedbackapp/templates/feedbackapp/thanks.html

<!DOCTYPE html> 
<html lang="en"> 
<head> 
    <meta charset="UTF-8"> 
    <title>Thanks!</title> 
</head> 
<body> 
<p>Thanks for your feedback.</p> 
</body> 
</html>

feedbackapp/urls.py

from django.conf.urls import url 
from .views import record_feedback, thanks 


urlpatterns = [ 
    url('', record_feedback, name='feedback'), 
    url('thanks/', thanks, name='thanks'), 
]

anonfeed/urls.py

from django.conf.urls import url, include 
from django.contrib import admin 

urlpatterns = [ 
    url(r'^admin/', admin.site.urls), 
    url('', include('feedbackapp.urls'), namespace='feedbackapp'), 
]

這幾乎是如果thanks觀點不符合URL和模板關聯。

交換你的'feedbackapp.urls.urlpatterns'的順序，或者把'$'的'feedback'模式，以表明它僅應如果後面什麼也沒有，那麼去那裏，否則無論你去哪個網址，它都會進入你的「反饋」視圖。 – Jorden

您的空正則表達式覆蓋thanks的正則表達式。更改以下行：

url('', record_feedback, name='feedback'),

到

url('^$', record_feedback, name='feedback'),

當它是簡單的事情時就得愛。謝謝！ – nerdenator
