EctoAQL

Installation

Step 1:

The package can be installed by replacing ecto_sql with ecto_aql in your Phoenix Project's mix.exs file:

def deps do
  [
    {:ecto_aql, git: "git://github.com/SquashConsulting/ecto_aql.git"}
  ]
end

Step 2:

Inside <YOUR-PHOENIX-PROJECT>/priv/repo/migrations/.formatter.exs add ecto_aql

- import_deps: [:ecto_sql]
+ import_deps: [:ecto_aql]

Step 3:

Inside <YOUR-PHOENIX-PROJECT>/lib/hopper/repo.ex replace the default use macro with:

use EctoAQL.Repo,
  otp_app: :the_name_of_your_app

Step 4:

Run ArangoDB on http://localhost:8529 and create a database.

Inside <YOUR-PHOENIX-PROJECT>/config/dev.exs replace the default Repo config with:

config :your_otp_app, YourApp.Repo,
  pool_size: 10,
  database: "name_of_the_database",
  show_sensitive_data_on_connection_error: true

Step 5:

cd into the root of your Phoenix project directory and run:

$ mix ecto.setup.arango

Setup Complete!

This command will create a system collection called _migrations in the _system db of Arango and will create a MASTER migration document that will be used to keep track of the migrated versions of your database.

Available Commands

To generate migrations run:

$ mix ecto.gen.migration create_users

* creating priv/repo/migrations/20200114155636_create_users.exs

This will create a base migration module with two main functions:

  • up to migrate the db
  • down to rollback the db

Inside the file you can use the publicly available functions from EctoAQL.Repo module like so:

defmodule YourApp.Repo.Migrations.CreateUsers do
  alias Elixir.YourApp.Repo

  def up do
    Repo.create_collection("users", :document)
  end

  def down do
    Repo.drop_collection("users")
  end
end

To run the migration run:

$ mix ecto.migrate # or mix ecto.migrate up

Successfully Migrated 20200114155636_create_users.exs

To rollback run:

$ mix ecto.migrate rollback

Successfully Rolled Back 20200114155636
