NoReverseMatch：未找到参数“(1,)”的“完整”反转。尝试了 1 个模式：['complete/']

urls.py

from django.conf.urls import url
from . import views

urlpatterns = [
url('', views.index, name= 'index'),
url('add', views.addTodo, name ='add'),
url('complete/<todo_id>', views.completeTodo, name='complete'),
url('deletecomplete', views.deleteCompleted, name='deletecomplete'),
url('deleteall', views.deleteAll, name='deleteall')
]

views.py（程序的一部分）

def completeTodo(request, todo_id):
todo = Todo.objects.get(pk=todo_id)
todo.complete = True
todo.save()

return redirect('index')

index.html（程序的一部分）我想这就是问题所在。

 <ul class="list-group t20">
                    {% for todo in todo_list %}
                        {% if todo.complete %}
                        <li class="list-group-item todo-completed">{{ todo.text }}</li>
                        {% else %}
                        <a href="{% url 'complete' todo.id %}"><li class="list-group-item">{{ todo.text }}</li></a>
                        {% endif %}
                    {% endfor %}
                </ul>

您的正则表达式是错误的：

而不是这个：

url('complete/<todo_id>', views.completeTodo, name='complete'),

尝试这个：

url(r'^complete/(?P<todo_id>\d+)$', views.completeTodo, name='complete'),

或者如果你想使用path

path('complete/<int:todo_id>', views.completeTodo, name='complete'),

EDIT

由于您使用的是 Django 1.*，因此您不能使用path()设置所有 URL 的正确方法是url正则表达式

Note

'^'：匹配必须从字符串或行的开头开始。

'$'：匹配必须出现在字符串的末尾

'\d+'：匹配所有数字

The r在开始时代表regex

url(r'^$', views.index, name= 'index'),
url(r'^add$', views.addTodo, name ='add'),
url(r'^complete/(?P<todo_id>\d+)$', views.completeTodo, name='complete'),
url(r'^deletecomplete$', views.deleteCompleted, name='deletecomplete'),
url(r'^deleteall$', views.deleteAll, name='deleteall')
