Weather app using Django - Python
Our task is to create a Weather app using Django that lets users enter a city name and view current weather details like temperature, humidity, and pressure. We will build this by setting up a Django project, creating a view to fetch data from the OpenWeatherMap API, and designing a simple template to display the results. Step-by-step, we’ll implement the core functionality to build a working weather app.
Prerequisites:
Basic Setup
Create a virtual environment, and install the packages:
pip install Django
Step 1: Create a Django Project
Start a new Django project named weather:
django-admin startproject weather
Step 2: Navigate to the Project Directory
cd weather
Step 3: Create a Django App
Create an app called main:
python manage.py startapp main
The directory structure should look like this:
Step 4: Add the main App to Settings
Open weather/settings.py and add 'main' to the INSTALLED_APPS list:
Step 5: Configure URLs
Edit weather/urls.py to include the todo app views:
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('main.urls')),
]
Step 6: Define URLs for main App
Create main/urls.py and add:
from django.urls import path
from . import views
urlpatterns = [
path('', views.index),
]
Step 7: Create the View
Edit main/views.py to fetch and process weather data:Note: Obtain your API key from "OpenWeatherApp" Replace "your_api_key_here" in views.py with your actual API key.
Step 7: Create the Template
Create main/templates/main/index.html with this content:
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8" />
<title>weather</title>
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css" />
<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<!-- Latest compiled JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>
</head>
<body>
<nav class="row" style="background: green; color: white;">
<h1 class="col-md-3 text-center">weather</h1>
</nav>
<br /><br />
<center class="row">
<form method="post" class="col-md-6 col-md-offset-3">
{% csrf_token %}
<div class="input-group">
<input type="text" class="form-control" name="city" placeholder="Search" />
<div class="input-group-btn">
<button class="btn btn-default" type="submit">
<i class="glyphicon glyphicon-search"></i>
</button>
</div>
</div>
</form>
</center>
<div class="row">
{% if country_code and coordinate and temp and pressure and humidity %}
<div class="col-md-6 col-md-offset-3">
<h3>Country Code: {{ country_code }}</h3>
<h5>Coordinate: {{ coordinate }}</h5>
<h5>Temperature: {{ temp }}</h5>
<h5>Pressure: {{ pressure }}</h5>
<h5>Humidity: {{ humidity }}</h5>
</div>
{% endif %}
</div>
</body>
</html>
Step 9: Make Migrations (Optional)
Run migrations to keep your environment updated (even though this app has no models):
python manage.py makemigrations
python manage.py migrate
Step 10: Run the Server
Start the Django development server:
python manage.py runserver
Open your browser at "http://127.0.0.1:8000/", enter a city name, and check the weather!
