Web Apps with web2py: Database Connectivity & the Model
Lesson Objectives
Web Apps with web2py: Database Connectivity & the Model
- discover the key concepts covered in this course
- install a MySQL database which will later be integrated with a web2py app
- identify the steps involved in connecting a web2py app to a MySQL database
- recognize how web2py models are translated to relational database tables
- illustrate how to use the default web2py app interface to sign up new users
- recognize how to insert rows into a table using the web2py admin interface
- recall how to use web2py's built-in grid widget to view the contents of a database table
- identify how to use the web2py grid to search the contents of a database table
- summarize the key concepts covered in this course
Overview/Description
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.

Overview/Description
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.

Overview/Description
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
Lesson Objectives
Web Apps with web2py: The Controller & View
- discover the key concepts covered in this course
- create a simple web2py app starting with the default app
- identify how to update the content of the index template to create a new homepage for the app
- demonstrate how to set up a controller and view, and the relationship which exists between them
- recall how views are affected by the return types for their corresponding controllers
- recognize how to pass query parameters through a URL to a web2py app
- illustrate how to use forms to submit POST data to a web2py app
- recognize how request and session variables can be accessed in web2py

- use the cloud-hosted PythonAnywhere service to deploy a web2py app to end users
- summarize the key concepts covered in this course
Overview/Description
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.

Overview/Description
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.
