Options, like ssl, timeout and pool_size. URL can include query parameters to override shared and adapter-specific For example, the configurationĪbove could be rewritten to: config :my_app, Repo, url : schema can be of any value. :stacktrace- when true, publishes the stacktrace in telemetry events Use the :repo property in the event metadata for distinguishing Should keep the :telemetry_prefix consistent for each repo and Note that if you have multiple databases, you 'Telemetry Events' section to see which events we recommendĪdapters to publish.

It must always point to a subdirectory inside the priv directory :priv - the directory where to keep repository data, like :name- The name of the Repo supervisor process In spite of this, the following configuration values For this particular example, you can checkįor more information.

For example, the repository: defmodule Repo do use Ecto.Repo, otp_app : :my_app, adapter : endĬould be configured with: config :my_app, Repo, database : 'ecto_simple', username : 'postgres', password : 'postgres', hostname : 'localhost' The :otp_app should point to an OTP application that has When used, the repository expects the :otp_app and :adapter as For example, Ecto ships with a Postgres adapter that If you would like to read more articles about Elixir, be sure to follow us on Twitter or Dev.Settings View Source Ecto.Repo behaviour (Ecto v3.10.2)Ī repository maps to an underlying data store, controlled by theĪdapter. If Thinking in Ecto was not enough and you would like to see another conference talk by Darin Wilson, this one is a bit more in-depth. It’s curated by Dashbit, the company working on Elixir.

Elixir School’s Ecto section contains a lot of useful info and code examples on changesets and queries. It’s well written and should be able to answer most of your questions. This is a rather large YouTube playlist of 13 videos that goes through some of the basics of Ecto. I’m a fan of the content Alchemist Camp is putting out, and this is no different. Ecto basics playlist from Alchemist Camp.If you are one of those people that can read a book, it can be useful to pick it up. Not much to say – it is the premier Ecto book. It covers what is special about Ecto, and why it is the way it is.

If you check out just one resource from this list, watch this talk. Here is a load of awesome beginner- and intermediate-level materials that you can check out to learn more about the toolkit. Each of the items I talked about are covered better in different places I only tried to bring all the knowledge in one place for your convenience. I’ve given a quick introduction, but there’s a lot still to explore out there. If you would like to read more about validations and constraints, this article is very nice. There are a lot of ready-made validations present, but you can also write your own custom validation functions and call them with validate_change. Iex(18)> changeset = _required(changeset, ) Now, we can play around with the database.įirst off, some alias preparations: iex(1)> alias Blog.Repo Schema-less queries, pure SQL instead of Ecto.Query, just using changesets for data validation – you want it, you can do it. While Ecto is frequently called a framework, it consists of a few modules, most of which you can use or not use, depending on your preferences. But you can technically use it to connect to whichever data source your heart prefers like MongoDB or ETS, among other things. For example, by default, Ecto is made to connect to SQL databases like MySQL & PostgreSQL. While it can cause some headaches in the start, it prevents you from making mistakes that you will forever remember when your project goes viral on Product Hunt.Ĭonfigurable. For example, if you don’t preload associated items, the framework will not fetch them for you. Ecto is explicit about what is happening: there is not so much behind-the-scenes magic as in other libraries. Generally, Ecto offers the same benefits as other things in the Elixir ecosystem: we focus on modularity and explicitness and of course it has macros.Įxplicit. If you are using Phoenix and Elixir, the chance is you will use Ecto. Most likely, the choice of using Ecto will come as a consequence of other choices that you’ve made.
