Question

我有两个依赖的Django模板，也就是说，一旦我在第一个模板的表单上点击提交，我应该重定向到第二个模板中查看结果但我遇到错误：{{1}其中 tickets_per_day_results 是应显示结果的模板。

表单

NoReverseMatch at /tickets_per_day_results/

Views.py

class DropDownMenuForm(forms.Form):
    week = forms.ChoiceField(choices=[(x,x) for x in range (1,53)])
    year = forms.ChoiceField(choices=[(x,x) for x in range (2016,2021)])

urls.py

class ChartData8(APIView):

def get(self, request):
    template_name = 'personal_website/tickets_per_day_no_results.html'
    form = DropDownMenuForm()
    return render(request, template_name, {'form': form})

def post(self, request):
    template_name = 'personal_website/tickets_per_day_results.html'
    #print(template_name)
    if request.method == "POST":
        year = request.POST.get('select_year', None)
        week = request.POST.get('select_week', None)
        ... do stuff ....
    return render(request, template_name, data)

模板1：tickets_per_day_no_results ：这是您从下拉菜单中选择选项的第一个模板。我的猜测是对第二个模板的操作导致了问题。

url(r'^tickets_per_day_no_results/$', ChartData8.as_view()),
url(r'^tickets_per_day_results/$', ChartData8.as_view()),

模板2：tickets_per_day_results ：这是您应该看到结果的第二个模板。

{% extends "personal_website/header.html"%}
{% block content %}
<h3>Please, select the year and week number to retrieve the data.</h3>
<form id="search_dates" method="POST" action="/tickets_per_day_results/"> {% csrf_token %}
<h6>Select year</h6>

<div class="row">
    <div class="col-sm-8">
        <select name="select_year">
            <option value = {{form.year}}></option>
        </select>
    </div>
    <div class="col-sm-8">
        <h6>Select week</h6>
        <select name="select_week">
            <option value= {{form.week}}></option>
        </select>
        <button type="submit">Search</button>
    </div>
</div>
</div>

如何解决此问题，以便在浏览器的第二个模板中看到结果？

Answer 1

这是在某些应用程序中定义的吗？是否在表格中完全提到了网址？ “/ tickets_per_day_results /”。可能是因为你错过了与app相关的url后缀，你在root urls.py中提到了这个后缀。也许“something_here / tickets_per_day_results /".

Django模板不在浏览器中显示结果
