   Step 2: Add the PHP Repository

   The default Ubuntu repositories might not have the latest PHP versions. To get PHP 8.2, you'll need to add the ondrej/php repository:

4. Install the software-properties-common package if it’s not already installed:

   sudo apt install software-properties-common -y
   Add the PHP repository:

   sudo add-apt-repository ppa:ondrej/php

   For Apache:
   Install the PHP 8.2 module for Apache:
   sudo apt install libapache2-mod-php8.2 -y
    
    Disable the old PHP module and enable the new one:
   sudo a2dismod php8.1

Copy 000-default.com.conf to create a new file in /etc/apache2/sites-available:

$ cd /etc/apache2/sites-available
$ sudo cp 000-default.com.conf example.com.conf

    -include that directory to sites available using <directoryname>.conf file- sudo nano /etc/apache2/sites-available/directoryname.conf

Step-by-step tutorial for beginners to set up a Django project on Ubuntu:

 Step 1: Install Python and Pip

 Update the package list:

sudo apt update 

Install Python 3 and pip:
sudo apt install python3 python3-pip -y

Verify the installation:
 python3 --version
pip3 --version

Step 2: Install Virtual Environment

Install venv (if not installed):

sudo apt install python3-venv -y
 

Create a virtual environment: Navigate to your project directory and create the environment:

mkdir my_django_project
cd my_django_project
python3 -m venv env
 

Activate the virtual environment:

source env/bin/activate
Your terminal prompt should now show (env).

 

Step 3: Install Django

Install Django:

pip install django
 

Verify the installation:

django-admin --version

Step 4: Start a Django Project 

Create a new project:

django-admin startproject mysite

Navigate to the project directory:

 cd mysite
To verify that everything is working, run the Django development server.

python3 manage.py runserver
Step 7: Create a View

Edit myapp/views.py:

from django.shortcuts import render

def home(request):
    return render(request, 'home.html')

Create a URL pattern: Edit mysite/urls.py to include your app’s view: 

from django.contrib import admin
from django.urls import path
from myapp import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', views.home),
]

Run the server again:
python3 manage.py runserver

Step 8: Create a Template

mkdir -p myapp/templates
 

Create an HTML file myapp/templates/home.html:

<!DOCTYPE html>
<html>
<head>
    <title>Django App</title>
</head>
<body>
    <h1>Welcome to Django!</h1>
</body>
</html>

Modify the view to render the template: In myapp/views.py:
from django.shortcuts import render

def home(request):
    return render(request, 'home.html')
 

Run the server and refresh the browser. You should now see the HTML content rendered.

2. v=spf1 include:_spf.mlsend.com include:_spf.mlsend.com include:_spf.elasticemail.com include:spf.protection.outlook.com -all

Combined

3.  v=spf1 include:_spf.elasticemail.com include:spf.protection.outlook.com include:_spf.mlsend.com -all
   

4. Save Changes:

   • Save the changes to your DNS records.

Verify the SPF Record

After updating the SPF record, verify that it has been correctly applied:

• Use MXToolbox SPF Lookup https://mxtoolbox.com/SuperTool.aspx to check the SPF record for your domain.
• Ensure that the record includes all necessary includes (_spf.elasticemail.com, spf.protection.outlook.com, _spf.mlsend.com).

Adding Meta Tags

 

Steps to Implement

How to check if code is changed from LUMEN to LARAVEL

 Here are some ways to check your code after your team migrated it from Lumen to Laravel:

Here are some ways to check your code after your team migrated it from Lumen to Laravel:

General checks:

• Project Structure:
  • Verify the Laravel directory structure. Laravel has a specific directory layout with folders like app, config, resources, etc. Ensure these folders exist and contain the expected files.
• Configuration:
  • Check the composer.json file to see if Laravel dependencies are installed.
  • Review the config directory. Key Laravel configuration files like app.php, database.php, etc. should be present and configured correctly.
• Autoloading:
  • Ensure the autoload section in composer.json reflects the Laravel PSR-4 autoloading structure.
• Routing:
  • Look for the routes directory. Laravel uses routes defined in this directory for handling requests. Ensure routes are migrated properly from Lumen.
• Controllers:
  • Verify that controllers are located in the app/Http/Controllers directory (default Laravel location) and use Laravel controller features like dependency injection and middleware.

Framework-specific checks:

• Lumen-specific code: Identify and remove any Lumen-specific code that is no longer relevant in Laravel. This could include custom service providers, facades, or helper functions.
• Laravel features: Look for usage of new Laravel features like middleware, Eloquent ORM, or service providers that may have replaced Lumen functionality.

Testing:

• Unit Tests: Run any existing unit tests to ensure core functionalities still work after the migration.
• Manual Testing: Manually test critical functionalities of your application to identify any regressions introduced during the migration.

Additional resources:

• Laravel Documentation: The Laravel documentation provides a good starting point for understanding the framework and its features: https://laravel.com/docs/11.x/installation
• Upgrade Guide: If your team migrated from a specific Lumen version, there might be an official upgrade guide from Laravel that details specific migration steps: https://laravel.com/docs/9.x/upgrade

By following these steps and referencing the resources, you can gain a good understanding of the changes made during the migration and identify any potential issues. Remember, the specific checks will depend on the complexity of your application and the extent of the migration.
