simple is better than complex

Highcharts is, in my opinion, one of the best JavaScript libraries to work with data visualization and charts out there. Even though Highcharts is open source, it’s a commercial library. It’s free for use in non-commercial applications though.

In this post, I will share some tips to help you improve the design of your Django Models. Many of those tips are related to naming conventions, which can improve a lot the readability of your code.

First, let’s get those terms out of our way. The REST acronym stands for Representational State Transfer, which is an architectural design. Usually when we use the term RESTful, we are referring to an application that implements the REST architectural design. API stands for Application Programming Interface, which is a software application that we interact programmatically, instead of using a graphical interface. In other words, we interact with it at a lower level at the source code, writing functions and routines.

Dependent or chained dropdown list is a special field that relies on a previously selected field so to display a list of filtered options. A common use case is on the selection of state/province and cities, where you first pick the state, and then based on the state, the application displays a list of cities located in the state.

This is a very common problem many developers face in the early stages of the development of a new project, and it’s also a question I get asked a lot. So, I thought about sharing my experience with previous Django projects on how to handle multiple user types.
