The first thing to check when a No Reverse Match occurs in Django

NoReverseMatch

When there is a chobomis that you still do.

The cause is mostly URL dispatcher

myapp/urls.py


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

urlpatterns = [
    url(r'^', views.myapp_index, name='myapp_index'),
]

As a countermeasure, of course, add code.

myapp/urls.py


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

urlpatterns = [
    url(r'^', views.myapp_index, name='myapp_index'),
    url(r'^delete/', views.data_delete, name='data_delete'),
]

This way to insert in the template

{% url 'myapp:data_delete' %}

'namespace:name'

Because it is a rule of, if not a valid view function or pattern name. Appears, it was a story to review urls.py.
