Basic Setup : Change directory to weather – cd weather

Start the server – python manage.py runserver

To check whether the server is running or not go to a web browser and enter http://127.0.0.1:8000/ as URL. Now, you can stop the server by pressing

ctrl-c

Implementation :

python manage.py startapp main

Goto main/ folder by doing : cd main
and create a folder with index.html file: templates/main/index.html

Open the project folder using a text editor. 
The directory structure should look like this :

Now add main app in settings.py

Edit urls.py file in weather :

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
path(‘admin/’, admin.site.urls),
path(”, include(‘main.urls’)),
]

edit urls.py file in main :

from django.urls import path

from django.shortcuts import render
# import json to load json data to python dictionary
import json
# urllib.request to make a request to api
import urllib.request

def index(request):
if request.method == ‘POST’:
city = request.POST[‘city’]
”’ api key might be expired use your own api_key
place api_key in place of appid =”your_api_key_here ” ”’

# source contain JSON data from API

source = urllib.request.urlopen(
‘http://api.openweathermap.org/data/2.5/weather?q =’
+ city + ‘&appid = your_api_key_here’).read()

# converting JSON data to a dictionary
list_of_data = json.loads(source)

# data for variable list_of_data
data = {
“country_code”: str(list_of_data[‘sys’][‘country’]),
“coordinate”: str(list_of_data[‘coord’][‘lon’]) + ‘ ‘
+ str(list_of_data[‘coord’][‘lat’]),
“temp”: str(list_of_data[‘main’][‘temp’]) + ‘k’,
“pressure”: str(list_of_data[‘main’][‘pressure’]),
“humidity”: str(list_of_data[‘main’][‘humidity’]),
}
print(data)
else:
data ={}
return render(request, “main/index.html”, data)

Navigate to templates/main/index.html and edit it to index.html file.

Make migrations and migrate it:

python manage.py makemigrations
python manage.py migrate

Now let’s run the server to see your weather app.

python manage.py runserver
