I added my Urls bellow:

from django.conf.urls import include, url
from django.contrib import admin  
from django.urls import path  
from employee import views  

urlpatterns = [  
    path('index', views.show), 
    path('admin/', admin.site.urls),  
    path('emp', views.emp),  
    path('show',views.show),  
    path('edit/<int:id>', views.edit), 
    path('update/<int:id>', views.update),  
    path('delete/<int:id>', views.destroy),  
]

View:

from django.shortcuts import render, redirect  
from employee.forms import EmployeeForm  
from employee.models import Employee  
# Create your views here.  
def emp(request):  
    if request.method == "POST":  
        form = EmployeeForm(request.POST)  
        if form.is_valid():  
            try:  
                form.save()  
                return redirect('/show')  
            except:  
                pass  
    else:  
        form = EmployeeForm()  
    return render(request,'index.html',{'form':form})  
def show(request):  
    employees = Employee.objects.all()  
    return render(request,"show.html",{'employees':employees})  
def edit(request, id):  
    employee = Employee.objects.get(id=id)  
    return render(request,'edit.html', {'employee':employee})  
def update(request, id):  
    employee = Employee.objects.get(id=id)  
    form = EmployeeForm(request.POST, instance = employee)  
    if form.is_valid():  
        form.save()  
        return redirect("/show")  
    return render(request, 'edit.html', {'employee': employee})  
def destroy(request, id):  
    employee = Employee.objects.get(id=id)  
    employee.delete()  
    return redirect("/show")

I think the error says the template does not exist but the templates exist. Please inform me what is wrong in my application.

Answer 1

Here, your troubles come from your understanding of your project architecture. As you can see in your screenshoot here

Your template files are in the */DjangoWebProject5/employee/templates/ employee/

So you have too call them with the right path like 'employee/index.html'

def emp(request):  
    if request.method == "POST":  
        form = EmployeeForm(request.POST)  
        if form.is_valid():  
            try:  
                form.save()  
                return redirect('/show')  
            except:  
                pass  
    else:  
        form = EmployeeForm()  
    return render(request,'employee/index.html',{'form':form})  ## Here 'employee/index.html'

You can fix that on all your views.

Answer 2

Check this

It appears that TEMPLATE_DIRS was used prior to 1.8 but in the current version it has changed to a DIRS option in the TEMPLATES setting.

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [
        '/home/html/templates/lawrence.com',
        '/home/html/templates/default',
    ],
},

]
