The article has the title of ‘How to Solve Error Message : AttributeError: ‘str’ object has no attribute ‘get’ in Django’ and it exist in this link.

Django Application Configuration and Setting

Before moving on, the following below are the Django-based application description :

First of all, the existence of a Django-based application in the Django project’s folder. In this context, the application name is ‘sysapp’ as an example. It exist in the installed application list inside ‘settings.py’ file as file which has the responsible for defining the project configuration. Those configuration lines exist below :
```
# Application definition
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'crispy_forms',
    'sysapp',
]
```
Read an article with the title of ‘How to Create a New Application using Django Web-based Framework in Ubuntu Linux via Command Line’ in this link to create a Django-based application. The command for doing that is simple. Just execute ‘django-admin startapp app_name’ where in this example, ‘app_name’ is ‘sysapp’. Just choose any preferable name accordingly

Next, using the ‘urls.py’ file, define the URL for displaying the page. This is the content of the file :

from django.contrib import admin
from django.urls import path, include, reverse
from django.views.generic import RedirectView
from . import views
urlpatterns = [
    path('', views.main),
]

The most important line exist below :

    path('', views.main),

Following after, it is including the ‘urls.py’ file of the application to the ‘urls.py’ file of the project. So, any URL address of the application is being accessed, the project recognize to process it further. Below is the content of the ‘urls.py’ file :
```
from django.contrib import admin
from django.urls import path, include, reverse
from django.views.generic import RedirectView
from . import views
urlpatterns = [
    path('admin/', admin.site.urls),
    path('sysapp', include('sysapp.urls')),
]
```
The most important from the above is in the following line :
```
    path('sysapp', include('sysapp.urls')),
```

After that, just create a file with the name of ‘views.py’ for the application. It is defining the function for displaying or printing the page. The following is the content of the file :

from django.shortcuts import render, redirect, HttpResponse
from django.template import loader
# Create your views here.
def main(request):
    return HttpResponse("templates/sysapp/main.html")

Last but not least, it is for defining the HTML static page file with the name of ‘main.html’. In case of the ‘main.html’ file, the content is simple and it is exist as follows :
```
<html>
  <head>
    <title>Test</title>
  </head>
  <body>
    <h2>Hello World</h2>
  </body>
</html>
```
So, the HttpResponse object will print it. But unfortunately, it is printing the actual string of the path. So, the following display will appear :
