If not, thereĪre plenty of tutorials out there to get you started. That you have a local MySQL server running and can import the SQL dump. Import that into your local MySQL database. If you’d like toįollow along, I’m going to be working with the Ergast Motor Racing Developer APIĪfter getting the dump, create a database (I’m calling mine f1) and The entire history of the sport and we are going to use that. There is a fantastic database online that contains Set up your projectįor this sample project, I’m going to continue with data from one of myįavorite sports: Formula 1 racing. To get my basic application up and running. Let’s also deal with an unusual primary key column name.īut really, all that isn’t hard at all with Elixir and Ecto. Set up the application to access a MySQL database. There are plenty of existing projects that use MySQL.

Furthermore, while most tutorials show you how to use Ecto with Postgres, So let’s explore creating a new Elixir application that interacts with an existingĭatabase. Plenty of existing projects that could stand to have a little Elixir love
Using Ecto with a new database is a great way to start a new project, there are One of the questions I got was about using Ecto with existing databases. There was some great feedback from people regarding my post on gettingĮcto in your non-Phoenix application ( From Zero to Ecto in 10 Minutes).

Note that mix test does not run the tests in the integration_test folder. Important linksĬlone the repo and fetch its dependencies: $ git clone Our main focus is on providingīug fixes and incremental changes.
With version 3.0, Ecto API has become stable. For PostgreSQL it is: defmodule MyApp.Repo do If you want to use another database, just choose the proper dependency from the table above.įinally, in the repository definition, you will need to specify the adapter: respective to the chosen dependency. Then run mix deps.get in your shell to fetch the dependencies. The supported databases and their adapters are: DatabaseĮcto_sql (requires Ecto v3.0+) + postgrexĮcto_sql (requires Ecto v3.5+) + ecto_sqlite3įor example, if you want to use PostgreSQL, add to your mix.exs file: defp deps do You need to add both Ecto and the database adapter as a dependency to your mix.exs file.

The Little Ecto Cookbook, a free ebook by Dashbit, which is a curation of the existing Ecto guides with some extra contents
Programming Ecto, by Darin Wilson and Eric Meadows-Jönsson, which guides you from fundamentals up to advanced concepts See the getting started guide and the online documentation for more information. Ecto is also commonly used to map data from any source into Elixir structs, whether they are backed by a database or not. Here is an example: # In your config/config.exs fileĬonfig :my_app, ecto_repos: Įcto is commonly used to interact with databases, such as PostgreSQL and MySQL via ( source code). Add :ecto to the list of dependencies in mix.exs: def deps doĮcto is a toolkit for data mapping and language integrated query for Elixir.
