Web Apps with web2py
Web Apps with web2py: Getting Started
web2py is a powerful and popular Python web application
- development framework firmly built on the Model-View-Controller
- (MVC) paradigm, a popular design pattern often used for building
- user interfaces (UIs). A popular alternative to Django – another
- popular full-stack web framework – web2py offers an easy setup and
- a built-in integrated development environment (IDE). In this
- course, explore the fundamentals of web requests and responses,
- examine how web browsers and web servers interact, and identify the
- role of HTML and HTTP. Next, learn how web apps are created with
- frameworks and examine important Python web development frameworks
- such as Django, Flask, molten, and web2py. After that, compare
- web2py and Django and learn web2py’s strengths and limitations.
- Finally, examine the web2py workflow, practice building your first
- simple web2py app, and explore the directory structure and support
- available for multiple languages and translation.
Web Apps with web2py: The Controller & View
web2py relies heavily on the Model-View-Controller (MVC)
- paradigm. The controller holds business logic in a web2py app, and
- the view file consists of HTML and has embedded Python code in the
- form of web2py template language. In this course, learn how to
- create your own web2py app. Start by working with the index view
- and About page, practice editing apps from your local machine using
- a familiar text editor, and compare the mapping between your
- machine's file structure and the web2py app directory structure.
- Next, examine the relationship between the controller and views,
- explore dictionaries and the view.html file, and identify important
- global variables such as response, request, db, and session. After
- that, explore session and request variables and how sessions are
- supported out of the box in web2py. Finally, learn how to deploy a
- simple app to a third-party web server such as PythonAnywhere.
Web Apps with web2py: Database Connectivity & the Model
Database connectivity is a crucial part of any full-stack web
- application and is the most convenient manner to persistently store
- data like user login credentials. web2py is built on the
- Model-View-Controller (MVC) paradigm with the model focused on
- connecting to databases and managing data in external sources. In
- this course, study the role of the model in web2py apps.
- Investigate the db.py file and learn how to integrate MySQL with
- web2py while using the MySQL database as a backend for your web
- apps. Next, explore how to install the MySQL server and MySQL
- Workbench tool, and practice integrating web2py with these
- technologies. Finally, work with the SQLFORM.grid widget, which is
- an extremely powerful and simple way to work with data from the
- model and incorporate it into your app.
Web Apps with web2py: Working with Prebuilt Bootstrap Templates
For full-stack web developers, frameworks like web2py help you
- construct all of the business logic and get the wiring and the app
- details right. When it comes to app appearance and aesthetics, it's
- wise to rely on powerful frameworks like Bootstrap. Bootstrap helps
- you build sophisticated user interfaces (UIs) using design
- templates that incorporate both CSS and JavaScript code for
- typography, forms, buttons, etc. In this course, explore prebuilt
- Bootstrap templates and examine how to modify one to fit your use
- case. Then, learn how to set up a real-world web app for an
- e-commerce store built atop the Bootstrap functionality. Finally,
- learn how to allow users to register and sign in to your app, and
- identify the differences in the views presented to the admin user,
- a signed-in user, and a user who isn't signed in.
Web Apps with web2py: Decorators, Foreign Key Constraints, & Table Forms
When it comes to creating fully-fledged, professional-looking
- e-commerce web applications, there are a lot of little details that
- come into play. For instance, it’s important to have functionality
- such as a shopping cart, or perhaps the ability for a user to
- browse the category of merchandise they may be interested in. In
- this course, learn how to add product creation functionality for
- the admin of the e-commerce site. Then, practice implementing a
- shopping cart using foreign key constraints. Next, identify how to
- use web2py decorators such as a login decorator to ensure that a
- user has to log in before they can view certain functionality.
- Finally, examine how to add in filtering functionality so your
- users can select the category of products to browse.
