Here we'll see how structs can be used to format data. We'll start with an introduction to structs and then explore different ways to map external data to a struct, including using the ExConstructor package.
Phoenix contexts are modules that group associated functionality. To see how they work, we’ll build a simple blog with comments. This is a great episode for anyone new to Phoenix or wanting to see how contexts work.
In this episode we’ll explore another way to validate API params. We’ll update our existing example to use the Params package, which reduces much of the boilerplate of defining Ecto schemas and changesets.
