One of the Django framework’s main goals is to simplify the building process for developers. Django describes itself as a high-level Python web framework that promotes the rapid development of secure and maintainable websites. So, where does the Django ORM fit into this philosophy? Let’s take a look. This tutorial is not intended to dive deeply into the subject matter. We hope to introduce and take the first steps, priming you with underpinning knowledge to give you a starting point to explore the Django QuerySet further.

This talk was presented at PyBay2019 - 4th annual Bay Area Regional Python conference. See pybay.com for more details about PyBay and click SHOW MORE for more information about this talk. Description In Django, we have a powerful tool called ORM to manipulate databases easily. For small queries, it can be quite simple, but what happens when you need to do tricks like nested queries or computed values? One of the answers is query expressions. In this talk, we'll learn how to power-up queries with them by walking through comparisons and examples with a dataset. Abstract It's known that ORMs are a powerful tool to manipulate databases with ease. In Django, there are a set of out-of-the-box abstractions to help perform queries and shape them through annotations, aggregations, order by, and so on, hence saving one's time. A common solution to filtering when models grow larger over time is creating redundant fields; a better solution is using Django built-in resources called query expressions. Query expressions are smart yet straightforward functions that one can use to compute values on query execution and do string manipulation, calculations, among others, thus removing the burden of having unnecessary extra columns in our database. Using query expressions effectively can help to generate performant queries, avoiding potential inconsistencies and separating concerns. This talk focuses on further optimizing Django queries by walking through code comparisons and examples with a dataset, diving into subjects such as custom database functions, conditional expressions, and filtering so to answer questions about the data.

We design, implement and query an E-commerce inventory database in this case study. Creating a relational database is not and should not be hard to understand. This is not my words, but a quote from the Book “Database Design for Mere Mortals”. To help us develop the database in this case study, we follow components of the design methodology inspired by this excellent book which I recommend to all new developers. As we move through the design phase, it is essential to remember that I have tried to summarise many of the design stages, relevant details, and processes for use in the case study and the context in that you are new to database design. As and when we add other case studies to the course, I hope to unfold a more comprehensive design process.
