SwissSchema

A Swiss Army knife for your Ecto schemas

SwissSchema is a query toolkit for Ecto schemas. It makes it easy to manipulate data using Ecto schemas by implementing relevant Ecto.Repo Query API and Schema API functions, pre-configured to work specifically with the given Ecto schema.

Setup

Add swiss_schema as a dependency in mix.exs:

def deps do
  [
    # ...
    {:swiss_schema, "~> 0.5"}
  ]
end

Then, use SwissSchema in your Ecto schemas:

# lib/my_app/accounts/user.ex

defmodule MyApp.Accounts.User do
  use Ecto.Schema
  use SwissSchema, repo: MyApp.Repo

  def changeset(%User{} = user, params) do
    # here you set up your schema's changeset as usual
  end
end

That's it, you should be good to go.

Usage

When you use SwissSchema, a collection of pre-configured functions will be added to your Ecto schema module. The functions are equivalent to two important Ecto.Repo APIs: the Query API and the Schema API.

iex> User.get(1)
{:ok, %User{id: 1, ...}}

iex> User.get_by(email: "john@smiths.net")
{:ok, %User{id: 2, email: "john@smiths.net", ...}}

The motivation to have such API directly in your Ecto schema is to make function calls more idiomatic.

Check the docs for a complete list of available functions.

Alternatives

It seems that I'm not the only person in the world trying to improve this immediate Ecto's querying DX. Recently, I found some other projects similar to SwissSchema that creates some sort of querying tools out of Ecto schemas:

• Bee by Helder de Sousa 🇧🇷
• Ecto.Entity by Kamaro Lambert 🇰🇪
• EctoQuerify by Marko Bogdanović 🇷🇸
