Overview of this book

Django is a high-level web framework that eases the creation of complex, database-driven websites. It emphasizes on the reusability and pluggability of components, rapid development, and the principle of don't repeat yourself. It lets you build high-performing, elegant web applications quickly. There are several Django tutorials available online, which take as many shortcuts as possible, but leave you wondering how you can adapt them to your own needs. This guide takes the opposite approach by demonstrating how to work around common problems and client requests, without skipping the important details. If you have built a few Django projects and are on the lookout for a guide to get you past the basics and to solve modern development tasks, this is your book. Seven unique projects will take you through the development process from scratch, leaving no stone unturned. In the first two projects, you will learn everything from adding ranking and voting capabilities to your App to building a multiuser blog platform with a unique twist. The third project tackles APIs with Django and walks us through building a Nagios-inspired infrastructure monitoring system. And that is just the start! The other projects deal with customizing the Django admin to create a CMS for your clients, translating your web applications to multiple languages, and using the Elasticsearch search server with Django to create a high performing e-commerce web site. The seventh chapter includes a surprise usage of Django, and we dive deep into the internals of Django to create something exciting! When you're done, you'll have consistent patterns and techniques that you can build on for many projects to come.

The model


What information should we record for the data points? We definitely need the name of the node that is sending the data. We also need to record the time at which we got the data point so that we can figure out the latest status of the node. Of course, we need to know the type and value of the data point. The type of the data point is simply the name of the quantity that we are measuring, such as CPU usage, memory usage, uptime, and so on.

For now, I think these are all the things that we need to measure:

  • Node name

  • Date and time

  • Type

  • Value

While thinking about which fields we needed in our model, I thought of another approach. It involved having a different model for each data point type, so we could have Django models named SystemLoad, MemoryUsage, DiskUsage, Uptime, and so on. However, once I thought about it further, I figured out that doing so would be very restrictive as now we'd need to define a new model every time we wanted to measure something new. Having the type of the data...
