姜戈: NoReverseMatch在‘’。‘‘不是有效的视图函数或模式名称

Question

我试图从表单输入中检索数据并将它们插入到模型中。但我收到了这个错误：

[Error NoReverseMatch.“test-management/test/add_test/”不是有效的视图函数或模式名称。1

包含窗体.的.html文件

<form class="form" method="POST" action="{% url 'test-management/test/add_test/' %}">
                        {% csrf_token %}
                        <h2>Add Test</h2>
                        <div class="card-body">
                            <div class="form-group bmd-form-group">
                                <div class="input-group">
                                    <p>Name :</p>
                                    <input type="text" class="form-control" name="name" placeholder="Test Name...">
                                </div>
                            </div>
                            <div class="form-group bmd-form-group">
                              <div class="input-group">
                                  <p>Type :</p>
                                  <input type="text" class="form-control" name="type" placeholder="Test Type...">
                              </div>
                            </div>
                            <div class="form-group bmd-form-group">
                                <div class="input-group">
                                    <p>Date :</p>
                                    <input type="date" class="form-control" name="date" placeholder="Test Date...">
                                </div>
                            </div>
                        </div>
                        <div class="modal-footer justify-content-right">
                            <input type="submit" value="Add">
                            <a href="." class="btn btn-primary btn-link btn-wd btn-lg" id="close">Close</a>
                            <a href="#pablo" class="btn btn-primary btn-link btn-wd btn-lg" id="add_new">Add & New</a>
                            <a href="." class="btn btn-primary btn-link btn-wd btn-lg" id="add">Add</a>
                        </div>
                    </form>

错误可能是由表单的操作引起的，但我不知道如何纠正它。

urls.py

from test_management.views import (test_list, subject_list, topic_list, question_list, import_question, add_test)

urlpatterns = [
    url(r'^test-management/test/add_test/', add_test, name='add_test'),
]+ static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

views.py

from django.shortcuts import render
from django.http import HttpResponse
from django.http import HttpResponseRedirect
from .models import Test

def add_test(request):
    if request.method == 'POST':
        test_name = request.POST.get('name')
        test_type = request.POST.get('type')
        test_date = request.POST.get('date')
        test_obj = Test(test_name = test_name, test_type = test_type, test_date = test_date)
        test_obj.save()
        tests = Test.objects.all()
    return render(request, 'test_list.html', {'tests' : tests})

models.py

class Test(models.Model):
    # candidate_id = models.ForeignKey('Candidate', on_delete=models.CASCADE)
    # admin_id = models.OneToOneField('Admin', on_delete=models.CASCADE)
    test_name = models.TextField(max_length=45)
    test_type = models.TextField(max_length=45)
    test_date = models.DateField()
    create_date = models.DateTimeField(auto_now_add=True)

    def __str__(self): 
        return self.test_name

谢谢你帮我解决这个错误！

作为url标记的参数，您应该使用url，而不是正则表达式：

<form class="form" method="POST" action="{% url 'add_test' %}">

而不是

<form class="form" method="POST" action="{% url 'test-management/test/add_test/' %}">
