Visual Studio Code is a free source code editor developed my Microsoft.

We now need to write a piece of code that sends an email when a user instance is created. This is what Django signals are for, and this is a perfect occasion to touch this subject. Signals are fired before/after certain events occur in the application. We can define callback functions that are triggered automatically when the signals are fired. To make a callback trigger, we must first connect. Generating the queryset filter; Sorting the table by column; Searching. Parsing the search string; Deriving the Q() filter; Compound columns with different data types; Sorting.
