A Simple Password Generator Using Django With jQuery

In this tutorial we will create a Simple Password Generator With jQuery using django web framework. Django is a free and open source web application framework, written in Python. The official project site describes Django as "a high-level Python Web framework that encourages rapid development and clean, pragmatic design. So let's now do the coding... Getting Started First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/. After Python IDLE's is installed, open the command prompt then type "pip install Django", and hit enter. tut1 Wait for the django to be downloaded and installed at the same time. Then After that type "python -m django version" and hit enter to check if django is installed and what version of django is. tut2 Creating the App After setting django we will now create the web app for the web server. First create a new folder named "Python - Django A Simple Password Generator With jQuery", then cd to a newly created folder, then type "django-admin startproject website" and hit enter. A new folder will be created on the directory named 'website'. tut3 Running The Server After creating a project, cd to the newly created directory, then type "manage.py runserver" and hit enter to start the server running. The "manage.py" is a command of django-admin that utilize the administrative tasks of python web framework. Here is the image of python web server: tut4 Note: Type '127.0.0.1:8000' in the url browser to view the server. When there is code changes in the server just (ctrl + C) to command prompt to stop the server from running, then start again to avoid errors. Creating The Website This time will now create the web app to display the web models. First locate the directory of the app via command prompt cd, then type "manage.py startapp password" and hit enter. A new directory will be create inside the app named "password". tut5 Setting up The URL This time will now create a url address to connect the app from the server. First Go to website directory, then open urls via Python IDLE's or any text editor. Then import "include" module beside the url module and import additional module to make a redirect url to your site "from website import views". After that copy/paste the code below inside the urlpatterns.
  1. url(r'^$', views.index_redirect, name='index_redirect'),
  2. url(r'^password/', include('password.urls')),
It will be look like this:
  1. from django.conf.urls import include, url
  2. from django.contrib import admin
  3. from website import views
  4.  
  5. urlpatterns = [
  6.     url(r'^$', views.index_redirect, name='index_redirect'),
  7.     url(r'^password/', include('password.urls')),
  8.     url(r'^admin/', admin.site.urls),
  9. ]
Then after that create a view that will catch the redirect url. To do that create a file "views.py" then copy/paste the code below and save it as "views.py".
  1. from django.shortcuts import redirect
  2.  
  3. def index_redirect(request):
  4.     return redirect('/password/')
Creating The Path For The Pages Now that we set the connect we will now create a path for the web pages. All you have to do first is to go to password directory, then copy/paste the code below and save it inside "password" directory named 'urls.py' The file name must be urls.py or else there will be an error in the code.
  1. from django.conf.urls import url
  2. from . import views
  3.  
  4.  
  5. urlpatterns = [
  6.     url(r'^$', views.index, name='index'),
  7. ]
Creating A Static Folder This time we will create a directory to import the statics and templates. First go to the password directory then create a directory called "static", after that create a sub directory called "password". You'll notice that it is the same as your main app directory name, to assure the absolute link. This is where you import the css, js, etc directory. Creating The Views The views contains the interface of the website. This is where you assign the html code for rendering it to django framework. To do that first open the views.py, the copy/paste the code below.
  1. from django.shortcuts import render
  2.  
  3.  
  4. # Create your views here.
  5. def index(request):
  6.     return render(request, 'password/index.html')
Registering The App To The Server Now that we created the interface we will now then register the app to the server. To do that go to the website directory, then open "settings.py" via Python IDLE's or any text editor. Then copy/paste this script inside the INSTALLED_APP variables 'password'. It will be like this:
  1. INSTALLED_APPS = [
  2.     'password',
  3.     'django.contrib.admin',
  4.     'django.contrib.auth',
  5.     'django.contrib.contenttypes',
  6.     'django.contrib.sessions',
  7.     'django.contrib.messages',
  8.     'django.contrib.staticfiles',
  9. ]
Creating The Mark up Language Now we will create the html interface for the django framework. First go to password directory, then create a directory called "templates" and create a sub directory on it called password. index.html
  1. <!DOCTYPE html>
  2. <html lang="en">
  3.     <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1" />
  4.     {% load static %}
  5.     <link rel="stylesheet", type="text/css" href="{% static 'password/css/bootstrap.css' %}"/>
  6.     <title>Python - Simple Password Generator In Django</title>
  7. </head>
  8.     <nav class="navbar navbar-default">
  9.         <div class="container-fluid">
  10.             <a href="https://sourcecodester.com" class="navbar-brand">Sourcecodester</a>
  11.         </div>
  12.     </nav>
  13.     <div class="col-md-3"></div>
  14.     <div class="col-md-6 well">
  15.         <h3 class="text-primary" style="text-align:center;">Python - Django A Simple Password Generator With jQuery</h3>
  16.         <hr style="border-top:1px dotted #000;"/>
  17.         <center>
  18.             <div class="alert alert-danger" style="width:80%;">
  19.                 <label>Password</label><br />
  20.                 <input class="form-control" type='text' id="password" style="width:60%;"/>
  21.                 <br />
  22.                 <button class="btn btn-primary" id="generate">Generate</button>
  23.             </div>
  24.         </center>
  25.     </div>
  26. </body>
  27. <script src="{% static 'password/js/jquery-3.2.1.js' %}"></script>
  28. <script src="{% static 'password/js/passwordgen.js' %}"></script>
  29. </html>
Save it as "index.html" inside the website directory "sub directory of templates". Creating The jQuery Script Now we created the mark up language we will now then create the script that make the password generate. First go to the static directory then website directory after that select js directory, and then copy/paste the code below and save it as ''passwordgen.js".
  1. $(document).ready(function(){
  2.     $('#generate').on('click', function(){
  3.         var chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ123456789";
  4.         var pass = "";
  5.         for(var x = 0; x < 12; x++){
  6.             var i = Math.floor(Math.random() * chars.length);
  7.             pass += chars.charAt(i);
  8.         }
  9.  
  10.         $('#password').val(pass);
  11.     });
  12. });
Now try to run the server again, and see if all things are done. There you have it we successfully created a Simple Password Generator With jQuery using django framework.
