Shuffled Records in Phoenix
Posted on: 2017-12-12 I've written previously about a way to query for records in a shuffled order that works for pagination. The TL;DR was: use a shuffled (not random) ordering, based on a prime integer parameter. SELECT whatever FROM table ORDER BY large_integer_field % prime_integer_parameter -- modulo to shuffle LIMIT 10 OFFSET 0; Reuse the prime_integer_parameter with OFFSET 10 for subsequent
Case insensitive column in Phoenix
I wanted to have a case insensitive database column to store email address in the open source application I’m working on. I’m using PostgreSQL and there’s a nice extension that does exactly that - citext - so I gave it a try. I spent some time figuring things out so now I’m sharing the knowledge in this blog post. The instructions were tested in Elixir 1.5.3 / Phoenix 1.3.0 application. We start b
Beyond Functions in Elixir: Refactoring for Maintainability
Elixir can be a beautiful language, it has Ruby’s syntactic elegance, Lisp’s metaprogramming, and many functional features of languages like F#. The user has license to use many idioms and features: pattern matching, macros, behaviours, protocols, GenServers, ETS, etc. Working successfully in Elixir means choosing when to leverage a particular language feature for its ergonomics at the cost of gro
How Elixir's Ecto Promotes Well-Designed Applications
Oct 30 2017 How Elixir's Ecto Promotes Well-Designed ApplicationsAs consultants, our job is to provide the most value possible to our clients over the course of our engagement. As engineers, our desire is to build software that is a joy to work on. Thankfully, these goals are not mutually exclusive. In trying to meet both of them, it helps to focus on building well-designed applications. Since "we
Comparing dates and times in Elixir with Ecto - DockYard
If you are working with Ecto.DateTime in your Phoenix application you may make a comparison of two variables at some point: d1 = {{2015, 11, 30}, {0, 0, 0}} |> Ecto.DateTime.from_erl d2 = {{2015, 11, 29}, {0, 0, 0}} |> Ecto.DateTime.from_erl assert d1 > d2 The above ends up passing the assertion, but only by coincidence. What if you had a situation where you wanted to assert a comparison between t
Embedding Elixir Structs in Ecto Models
Postgres can store unstructured data such as arrays, json, and jsonb as of version 9.4. Ecto, Elixir’s database wrapper, provides first class support for serializing and deserializing Ecto structs and arrays into these native data types without sacrificing the expressiveness of Ecto models. Embedded records have all the things regular models have, such as structured fields, lifecycle callbacks, an
