Introduction
Unlike standard server-side programming languages, Python allows web developers to create web apps with logical, clear, and accessible code. Although Python is a versatile programming language compared to the other web programming languages, it doesn't have built-in web building capabilities. So how can one resolve this problem so you don’t have to switch to different languages?
This article will discuss one of the most popular web frameworks, the Web2py framework. Web2py enables developers to swiftly and effectively create unique online applications depending on various business needs.
To learn more about this widely used framework, read the entire article.
What is Web2py?
Web2py is a Python-based, accessible, and open-source web framework enabling agile development of database-driven online applications. It is a full-stack framework that includes all the elements a developer needs to create a fully functional web application.
In contrast to conventional patterns, the Web2py framework runs web applications using the Model-View-Controller (MVC) design.
Model: The model is an application component containing the data logic. Data from the database is retrieved and stored using the objects in the model.
View: The view is a program component that aids in rendering data displays to end-users. Data is retrieved from the Model for the data display.
Controller: The controller manages user interaction and is a component of the application. Controllers can read information from views, control user input, and send information to a particular model.
Features of Web2py
Offers a web-based IDE
Web2Py offers a web-based integrated development environment (IDE) for the web application that developers can use. Thanks to the admin app's one-click deployment feature, it is simpler for developers to install the Web2Py app in various contexts. Additionally, the admin interface's features make it easier for developers to complete routine web development chores, such as updating application files, erasing temporary files, interacting with databases, running tests, and looking up old tickets.
Streamlines Data-Driven Web Application Development
By supporting several popular relational and NoSQL databases, Web2Py makes it easier to construct data-driven online applications. Additionally, it facilitates and automatically migrates databases. Web2Py automatically modifies the table per each developer-changed table definition. Because of these features, many developers creating data-driven online applications choose Web2Py over alternative Python web frameworks.
Enables MVC architecture
Web2Py supports the MVC architectural pattern just like Django. By separating complicated web applications into models, views, and controllers, the design enables developers to streamline the creation of these apps.
Ensures Portable Web Applications
Applications built using Web2Py work flawlessly on popular web servers and operating systems. Additionally, the developers can set up Web2Py programs on various virtual private networks (VPNs) and cloud computing systems. Popular relational and NoSQL databases, including MySQL, MS SQL, Oracle, SQLite, PostgreSQL, Sybase, MongoDB, and Google App Engine, are also accessible to developers through the web framework.
Automates web application maintenance
Web2Py's web-based IDE and battery make it easy for developers to create unique web apps based on various business requirements quickly. In addition, the developers may readily use the web framework to manage and maintain the online applications.
Creating a Basic Web2py Program
We can utilize the administrative interface to add a new module, such as “Codingninjas" once the web2py application has started.
The administrative interface will request a password for authentication as the administrator has complete control over adding and changing any new web application.
The snippet above includes the page information, allowing the administrator to manage and see a list of all installed web2py applications. The web2py framework, by default, contains three programs. They are
An admin application that the user is actively deploying.
An example program that includes the online interactive documentation and a replica of the official Web2py website.
A welcome application. It contains the fundamental structure for all other web2py applications. It is often referred to as the scaffolding application. At startup, the application also extends a welcome to the user.
After a new application has been created, the user is directed to a page that includes the view, model, and controllers for that particular application.
The user can access the newly created application by going to the following URL: http://127.0.0.1:8000/admin/default/design/Codingninjas
When a person accesses the above URL, they are automatically presented with the above screen.
The update is performed in the default.py controller to print the "Codingninjas" message from the provided web application.
The default function for displaying the required output and returning the value is called "index()." As previously mentioned, the string "Welcome to Codingninjas" is used as the return value to display the output on the screen.
The output is shown as follows:
Frequently Asked Questions
What purpose does Web2py serve?
Python dynamic web content programming is made possible by Web2py for web developers. Although a web developer can still create a form from scratch if necessary, Web2py is intended to help decrease tiresome web development activities, such as making web forms from scratch.
Is Web2py an effective framework?
Simply put, Web2py is a completely Python-written, free, quick, safe online development framework that promotes utilizing Python wherever possible (model, view, controller). It is a useful framework for small web applications or prototypes.
Are web applications suitable for Python?
Python's essential features make it a popular choice for web development. First of all, Python is accessible, open-source, and free. But more crucially, it is also highly adaptive. Python enables web designers to build websites using various programming paradigms.
Why should you learn Web2py?
Web2py is a top-notch framework, yes. The simplicity of usage, from installation to learning to code to distribution to deployment, is a crucial objective of Web2py.
Conclusion
Overall, by offering a variety of features, Web2Py, a full-stack Python web framework, makes it easier to construct vast and complicated web applications. We also discussed its architecture and essential elements and created an application using the Web2py framework.
