Petition Against AI Research

Some big-time celebs (Musk, Wozniak, and more) have signed a petition to put a hold on the development of AI systems stronger than GPT-4. I’m really curious to hear what other people think about this. On the one hand, I get where they’re coming from, but even if it did happen, would it really make any difference? I kinda doubt it, to be honest.

As we all know, Django is a Python framework used for building complex web applications. Yet, it can also be used for building simple ones. In this tutorial, I’m going to show you how I built an English dictionary app, a simple Django project for beginners.

It takes time for a beginner to fully understand how Django works. But the key is consistency. If you keep building projects, you will gradually know enough to be dangerous with Django.

Scroll to the end to see the full code on GitHub!

A Dictionary App?

A dictionary is an application used to get a particular word’s meaning. No matter how proficient we are in English, some words are far beyond our understanding. There are also words we may not know how to pronounce efficiently, especially those originating from a different language.

Furthermore, we may want to know a synonym or antonym of a given word. This is where a dictionary comes in handy. With a dictionary, we get to know not only the meaning of a word but how it is pronounced, what parts of speech it belongs to, and how it is used in a sentence. Students, no doubt, appreciate the importance of having a dictionary.

How Will We Get The Data?

How will we build this dictionary app so that when users search for a particular word, they get the meaning?

We have two options. Either we use PyDictionary, a Python module and an API that scrapes an online dictionary website or we perform the web scraping ourselves. None of these methods comes without a drawback.

Recommended: Is Web Scraping Legal?

The drawback is the challenge that comes with web scraping. Many websites sometimes change their HTML structures to prevent people or bots from accessing their content. So, if an API is not actively maintained, it can quickly become useless. This is the case with PyDictionary. Therefore, we are going to perform web scraping.

Doing so will undoubtedly gain some valuable experience in web scraping, a very broad concept in Python programming. Still, we are at the mercy of website owners. They can change the HTML structures of their websites unexpectedly.

Prerequisites

This tutorial assumes you are familiar with Python, HTML, and Bootstrap. If not, please you are required to have at least a basic knowledge before attempting this project. Basic knowledge of Django, though not required, can speed up the learning process.

Getting started

Create a new folder for this project. Then you do the following:

1. Create a virtual environment
   python3 -m venv .venv
2. Activate the virtual environment
   source .venv/bin/activate
3. Install the required libraries in the virtual environment
   pip install django tzdata requests bs4
4. Create a requirements.txt file to keep a record of the module versions.
   pip freeze > requirements.txt

Creating Django Project and Application

i. Creating the project
django-admin startproject project .
This creates a folder called project in the current directory.

ii. Creating the application
python3 manage.py startapp dictionary
The manage.py file is an executable file used to run Django commands

iii. Applying migrations
python3 manage.py migrate

iv. Checking to see if the installation was successful
python3 mange.py runserver

Once you see the above image, you are good to go.

Registering the App

1. In settings.py file
   This step is important whenever an app is created. Navigate to the project folder. Open the settings.py file and scroll down to the INSTALLED_APPS section.

 # Application definition INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', # custom app 'dictionary', ]

We have registered the app in the settings.py file. The settings.py file is used to configure the whole project.

2. In the urls.py file
   Open the urls.py file in the project folder and add this:

 from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('dictionary.urls')), ]

We have registered the app-level URL. Let’s now create it.

Creating the App URL

This will be done inside the dictionary folder. Create a urls.py file inside the folder and add this:

from django.urls import path

from . import views urlpatterns = [ path('', views.homeView, name='home'), path('search', views.searchView, name='search'),

]

“from . import views” tells Django to import the views.py file residing in the dictionary folder.

The empty string indicates the home page URL which is http://127.0.0.1:8000/ if you are using the local server.

This is where users will be directed when the web page is opened.

For the 'search' string, the URL will be http://127.0.0.1:8000/search. We will be creating two functions in the views.py file as indicated.

Notice the name argument in the path() function, this is another way to refer to the URLs in the template files without using the exact URLs.

Creating Views

In this file, we are going to perform the web scraping we mentioned earlier. The first function, the homeView() is fairly simple. We just render the index.html page once the app is opened.

from django.shortcuts import render

import requests

from bs4 import BeautifulSoup as bs # Create your views here. def homeView(request): return render(request, 'index.html')

But the searchView() function is a little bit complex. We want to display three things when a user searches for the meaning of a word: meaning, synonyms, and antonyms.

So, we perform web scraping on two online dictionary websites. The first will display the meaning and the second will display the synonyms and antonyms.

def searchView(request): word = request.GET['search'] response = requests.get(f'https://dictionary.com/browse/{word}') response2 = requests.get(f'https://thesaurus.com/browse/{word}') if response: soup_1 = bs(response.text, 'html.parser') meaning = soup_1.find_all('div', {'value': '1'}) meaning_1 = meaning[0].getText() else: word = f'Sorry, we couldn\'t find your word {word} in our records.' meaning = '' meaning_ = '' if response2: soup_2 = bs(response2.text, 'html.parser') synonyms = soup_2.find_all('a', {'class': 'css-1kg1yv8 eh475bn0'}) synonym_list = [] for i in range(len(synonyms)): synonym_list.append(synonyms[i].text.strip()) antonyms = soup_2.find_all('a', {'class': 'css-15bafsg eh475bn0'}) antonym_list = [] for i in range(len(antonyms)): antonym_list.append(antonyms[i].text.strip()) else: synonym_list = '' antonym_list = '' results = { 'word': word, 'meaning': meaning_1, 'synonyms': synonym_list, 'antonyms': antonym_list } return render(request, 'search.html', results)

We import the requests module which uses the get() method to scrape the contents of the two websites.

Recommended: My First Python Get Request

The result is a cruel HTML code staring at you. BeautifulSoup, invaluable for web scraping does its job well to pull the data out of the HTML content. This now makes it possible to search the parsed data.

For our first search using the find_all() method from BeautifulSoup, we want a text wrapped in a div tag with the value 1. This is where the website owners kept the meaning of a particular word on the dictionary.com website.

So, we use the getText() method to get the text.

The second and third searches look similar to the first but instead of a div, we search in a tag. The words were kept in a tag to make it easy for visitors to be redirected to that particular word if they want to find the definition.

Instead of searching for a value, we search for a CSS class. We then append the results to their respective variables. If you are new to web scraping, you may wonder how we know where those particular words reside.

The answer is found in a browser’s developer tools, preferably Chrome Developer Tools. This is the reason I suggest familiarizing yourself with HTML before attempting this project.

Finally, we render the results on the search.html page. Notice the else statements. This is run if the word is not found on the website. Let’s now create the HTML files.

Creating Templates

Create a folder named templates in the current directory (not in the project or app folder). Then go to the settings.py file to let Django know of this development. In the file, import the os module. Then scroll to the TEMPLATES section and add this:

TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates')], # add these 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, },

]

Then create three files in the templates folder:

• base.html,
• index.html, and
• search.html.

The main HTML files will inherit from the base.html file. Open the base.html file and add the following:

<!DOCTYPE html>

<html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Dictionary App</title> <!-- CSS only --> <!-- we are getting bootstrap5 from the CDN --> <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.2.0-beta1/dist/css/bootstrap.min.css" rel="stylesheet">

</head> <body> <div class="container mt-4"> <div class="row"> <div class="mt-4 p-5 bg-success text-white rounded mb-3"> <h1>Django English Dictionary</h1> </div> <div class="col-md-12"> {% block content %} <!-- here we will inject the content of every page that inherits from the base page --> {% endblock %} </div> </div> </div>

</body> </html>

Then, in the index.html add the following:

<!-- the index page is inheriting from the base page -->

<!-- the extends tags are used for inheriting from the base page -->

{% extends 'base.html' %} <!-- the block content tags for containing content of the page -->

{% block content %} <form action="search"> <div class="input-group"> <input type="text" required class="form-control" name="search" placeholder="Search your favorite word......."> <div class="input-group-append"> <button class="btn btn-success" type="submit"> Search </button> </div> </div> </form> {% endblock %}

Recall in the searchView() function, we send a GET request to get the word input by our user from a form that bears the name 'search.' Can you now see it in the form?

There will be a problem if you use it otherwise. Finally, add the following to the search.html file.

<!-- SEARCH.HTML -->

{% extends 'base.html' %}

{% block content %} <div> <h2 align="center"> {{ word | title }} </h2> <br> <p> <b>Meaning: </b>{{meaning}} </p> <br> <p> <b>Synonyms: </b> {{ synonyms }}

</p>

<br>

<p> <b>Antonyms: </b> {{ antonyms }} </p> <p><a href="{% url 'home' %}>Home</a></p> </div>

{% endblock %}

We use Django templating language to render the results of the searchView() function to the HTML. Alright, we are done. Run the server once again and you should see something similar to the images below.

That is the index.html web page. Once you search for a word, the search.html page is displayed as you can see below.

Do you see how each of the pages inherits everything in the base.html file?

Conclusion

We have successfully come to the end of this project. I strongly believe you have learned a lot of things you can apply to your projects. If certain things aren’t clear you may wish to read other project articles.

QR code (Quick Response code) is a machine-readable pictorial format containing black and white squares. It is used for storing information like URLs, product ID, etc. It is a type of matrix barcode or a two-dimensional barcode.

It is a convenient form of storing and retrieving simple data and has become even more popular with the advent of smartphones. The camera in the smartphone can act as a reader and read the QR code and help to decipher the data stored in it.

This article gives many examples if you want a solution to generate QR codes in PHP. There are a lot of PHP libraries available to generate QR codes. This article uses the PHP QR code library.

1. Quick example

This quick example returns the QR code to the browser in one line. It produces the output as a PNG stream.

<?php

require_once __DIR__ . '/vendor/phpqrcode/qrlib.php'; // Displays QR Code image to the browser

QRcode::png('PHP QR Code :)');

Installing PHP QR code library

Download the latest library version and extract it into your application vendor folder. The source code downloadable in this article has the library.

All the examples in this article have the code to include the suitable library file to use its feature.

In a previous article, we have seen code for a PHP QR code generator using the tc-lib-barcode library.

2. Display the QR code using an HTML image

To display the QR code using an HTML image tag, link the HTML image source to the PHP file that returns the QR code PNG data.

The generate.php file returns the QR code in the below code using the PHP QrCode library. The HTML image refers to this file to show the QR code in the browser.

show-qr-code-in-HTML-img/generate.php

<?php

require_once __DIR__ . '/vendor/phpqrcode/qrlib.php'; // Displays QR Code image to the browser

QRcode::png('PHP QR Code :)');

<?php

require_once __DIR__ . '/../vendor/phpqrcode/qrlib.php'; // outputs image as PNG that can be refered to a HTML image 'src'

QRcode::png('PHP QR Code :)');

?>

show-qr-code-in-HTML-img/view.php

<img src="generate.php" />

2. Passing arguments to the QR code generator

Passing parameters to a QR code generator helps to perform dynamic processing about the parameter.

For example, we can pass a contact id to retrieve contact information to bundle it with the QR code output.

This example shows how to send parameters and process them in the QR generator.

The view.php file prepares the QR code parameter in PHP. Then, it sends it to the generate.php in query. This URL with the QR code parameter is specified to an HTML image source.

show-qr-code-in-html-img/view.php

<?php

// initialize PHP parameter to send to the QR code generator

$QRParameter = 1234;

?>

<img src="generate.php?id=<?php echo $QRParameter; ?>" />

In this generate.php file, it does simple manipulation to the passed argument. It prefixes a string with the GET parameter received and bundles the manipulated line to the QR code PNG.

show-qr-code-in-html-img/generate.php

<?php

if (empty($_GET['id'])) { echo "<b>ERROR:</b> Bad request. Required parameters are missing."; exit;

} else { require_once __DIR__ . '/../vendor/phpqrcode/qrlib.php'; $inputString = $_GET['id']; // Do not return anything to the browser ob_start("callback"); // Process the input string $codeText = 'DEMO - ' . $inputString; // end of processing $debugLog = ob_get_contents(); ob_end_clean(); // outputs QR code as a PNG data QRcode::png($codeText);

}

?>

3. Save the QR code on the server

This example saves the generated QR code on the server.

It defines the QR code data and the png file name suffix in an array. Then, it uses them while creating the target to save the QR code.

save-qr-code-in-server.php

<?php

require_once __DIR__ . '/vendor/phpqrcode/qrlib.php'; // how to configure silent zone (frame) size

$qrContent = array('content' => 'Contact information', 'slug' => 'contact-info'); $target = "uploads/qr-code-dir/";

$filePath = $target . 'ouput-qr-code-' . $qrContent['slug'] . '.png'; if (!file_exists($filePath)) { QRcode::png($qrContent['content'], $filePath);

}

?>

<img src="<?php echo $filePath; ?>" />

4. Configure QR code ECC Level, Zoom factor, and Frame size

The PHP QRCode Library defines constants for different ECC levels, Zoom factor, and Frame size. These factors are used for the following purposes when generating a QR code.

This program creates QR codes in L, M, Q, and H levels with appropriate QR constants.

• ECC level is the allowed percentage of damage without affecting reading data.
• Zoom factor is the allowed resolution that can be changed based on the use cases.
• Silent zone Frame size – The silent or quiet zone frame size varies based on different matrices. Setting the QR code above or equal to 4 blocks is recommended.

qr-code-ecc-level.php

<?php

require_once __DIR__ . '/vendor/phpqrcode/qrlib.php';

require_once __DIR__ . '/vendor/phpqrcode/qrconst.php'; $qrContent = 'Demo data to bundle into a QR code'; $target = "uploads/ecc-level/"; // generating QR code in the 4 ECC level

QRcode::png($qrContent, $target . 'l.png', QR_ECLEVEL_L);

QRcode::png($qrContent, $target . 'm.png', QR_ECLEVEL_M);

QRcode::png($qrContent, $target . 'q.png', QR_ECLEVEL_Q);

QRcode::png($qrContent, $target . 'h.png', QR_ECLEVEL_H); ?>

<img src="<?php echo $target; ?>l.png" />

<img src="<?php echo $target; ?>m.png" />

<img src="<?php echo $target; ?>q.png" />

<img src="<?php echo $target; ?>h.png" />

This program adds the zoom factor 1 to 4 with the QR_ECLEVEL_L ECC constant.

qr-code-pixel-zoom-factor.php

<?php

require_once __DIR__ . '/vendor/phpqrcode/qrlib.php'; $qrContent = 'Demo data to bundle into a QR code with zoom factor'; $target = "uploads/pixel-zoom-qr-code/"; // generating QR code with 4 ECC level and zoom factor

QRcode::png($qrContent, $target . 'l_1.png', QR_ECLEVEL_L, 1);

QRcode::png($qrContent, $target . 'l_2.png', QR_ECLEVEL_L, 2);

QRcode::png($qrContent, $target . 'l_3.png', QR_ECLEVEL_L, 3);

QRcode::png($qrContent, $target . 'l_4.png', QR_ECLEVEL_L, 4); ?>

<img src="<?php echo $target; ?>l_1.png" />

<img src="<?php echo $target; ?>l_2.png" />

<img src="<?php echo $target; ?>l_3.png" />

<img src="<?php echo $target; ?>l_4.png" />

This program creates QR codes with all these factors ECC, Zoom, and Frame constants of the library.

5. Add phone, email, and contact info to a QR code

This section has PHP examples to create QR codes to attach contact information.  It prepares the QR code content with the “tel:”. “sms:” and “mail:” links and attaches it to the QR code.

add-phone-to-call.php

<?php

require_once __DIR__ . '/vendor/phpqrcode/qrlib.php';

$target = "uploads/qr-code-phone/";

$phone = '(091)700-001-710';

// attache phone to call

$qrContent = 'tel:' . $phone;

QRcode::png($qrContent, $target . 'phone-to-call.png', QR_ECLEVEL_L, 3);

?>

<img src="<?php echo $target; ?>phone-to-call.png" /> 

add-phone-to-text.php

<?php

require_once __DIR__ . '/vendor/phpqrcode/qrlib.php';

$target = "uploads/qr-code-phone/";

$phone = '(091)700-001-710';

// Attach the phone to text

$qrContent = 'sms:' . $phone;

// generating

QRcode::png($qrContent, $target. 'phone-to-text.png', QR_ECLEVEL_L, 3);

?>

<img src="<?php echo $target; ?>phone-to-text.png" />

Attaching an email adds the mail subject and body as part of the mail recipient data. But the subject and the body parameters are optional.

add-recipient-to-send-mail.php

<?php

require_once __DIR__ . '/vendor/phpqrcode/qrlib.php';

$target = "uploads/qr-code-phone/";

$recipient = 'vincy@example.com';

$mailSubject = 'Enquiry';

$mailBody = 'Post enquiry content';

// Prepare QR content with email recipient, subject and body

$qrContent = 'mailto:' . $recipient . '?subject=' . urlencode($mailSubject) . '&body=' . urlencode($mailBody);

// Attach maileto link to the QRCode

QRcode::png($qrContent, $target. 'mail.png', QR_ECLEVEL_L, 3);

?>

<img src="<?php echo $target; ?>mail.png" /> 

This QR code example creates a v-card to bundle with the QR code. It includes basic details with the v-card.

This library allows adding more details to the QR code. For example, it can attach a contact avatar to a QR code.

In a previous article, we have seen how to generate and download a v-card for contact information.

save-vcard-to-qr-code.php

<?php

require_once __DIR__ . '/vendor/phpqrcode/qrlib.php';

$target = "uploads/qr-code-phone/";

// Contact details

$name = 'Example1';

$phone = '(091)700-001-711';

// QR code content with VACARD

$qrCode = 'BEGIN:VCARD' . "\n";

$qrCode .= 'FN:' . $name . "\n";

$qrCode .= 'TEL;WORK;VOICE:' . $phone . "\n";

$qrCode .= 'END:VCARD';

// Attaching VCARD to QR code

QRcode::png($qrCode, $target. 'vcard-qr-code.png', QR_ECLEVEL_L, 3);

?>

<img src="<?php echo $target; ?>vcard-qr-code.png" />
