Question

提交表单（输入）后，它将重定向到另一个页面（结果）。问题是它确实会转到所需的URL，但内容是空的。（如果我单独打开它不是空的）。提前感谢您的建议。

输入 - 网址

from inputform import views
from django.views.generic.list import ListView
from inputform.views import input
from django.views.generic import RedirectView
  urlpatterns = patterns('',
    url(r'^result_list/$',ResultView.as_view(),name='result'),
    (r'^input/$', RedirectView.as_view(url='/result_list/')),
      }

输入 - 视图

from django.http import HttpResponseRedirect
from django.shortcuts import render,render_to_response,get_object_or_404
from inputform.forms import Inputform
from inputform.models import Input
from dupont.models import Result
from django.views.decorators.csrf import csrf_exempt
from django.views.generic.list import ListView

@csrf_exempt

def input(request):
    if request.method == 'POST':
        form = Inputform(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
            print (cd['company'])
            form.save()
            return redirect(reverse,('','result_list'))

结果--views.py

＆＃13;

class ResultView(ListView):
    context_object_name = 'result_list'
    template_name = 'result_list.html'
    queryset = Result.objects.all()
 
def get_context_data(self, **kwargs):
        context = super(ResultView, self).get_context_data(**kwargs)
        context['input'] = Input.objects.all()
        return context

＆＃13;

结果 - html

<form action="result_list/" method="post">{% csrf_token %}
<div class="field" >
        <label> Select the Region:
        {{ form.regionlist }}
            {% for region in form.regionlist.choices %}
                 <option value="{{ val }}" {% ifequal data.val val %}selected {% endifequal %}></option>
            {% endfor %}
        </label>
    </div>

<div class="fieldWrapper"> 
    <p><input type="submit" value="Submit" /></p></div>
 </form>

如评论中所述，传递给reverse()的正确参数是“结果”，即网址的名称。

如果您使用django 1.7或更高版本，您可以跳过反向部分，django会自动为您完成。

def input(request):
if request.method == 'POST':
    form = Inputform(request.POST)
    if form.is_valid():
        cd = form.cleaned_data
        print (cd['company'])
        form.save()
        return redirect('result')
