NoReverseMatch：没有参数'（1，）'的'complete'反向。尝试了1个模式：['complete /< todo_id>']

问题描述

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）

views.py( portion of a program)

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

return redirect('index')

index.html（程序部分）我想这就是问题所在。

index.html(portion of program) I guess this is where the problem is coming.

 <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>

推荐答案

您的正则表达式表达式错误：

Your regex expression is wrong:

而不是此：

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

尝试以下操作：

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

或者如果您想使用

Or in case you want to use path

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

EDIT

因为您使用的是Django 1. *，所以不能使用 path（）
设置所有URL的正确方法是使用 url 正则表达式

Since you're using Django 1.*, you can't use path()The correct way to set up all your URLs is with url regex expressions

注意

'$'：匹配项必须位于字符串的结尾

'$': The match must occur at the end of the string

'\d +'：匹配所有数字

'\d+': Match all digits

r 开头代表 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')
