NoReverseMatch: Reverse for 'complete' with arguments '(1,)' not found. 1 pattern(s) tried: ['complete/']

Question

urls.py

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

urlpatterns = [
url(\'\', views.index, name= \'index\'),
url(\'add\', views.addTodo, name =\'add\')         


        

Answer 1

Your regex expression is wrong:

Instead of this:

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

try this:

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

Or in case you want to use path

path('complete/', views.completeTodo, name='complete'),

EDIT

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

Note

'^': The match must start at the beginning of the string or line.

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

'\d+': Match all digits

The r at the beginning stands for regex

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