Sqlite.Ecto

Sqlite.Ecto is a SQLite3 Adapter for Ecto.

Read the tutorial for a detailed example of how to setup and use a SQLite repo with Ecto, or just check-out the CliffsNotes in the sections below if you want to get started quickly.

Dependencies

Sqlite.Ecto relies on Sqlitex and esqlite. Since esqlite uses Erlang NIFs, you will need a valid C compiler to build the library.

Example

Here is an example usage:

# In your config/config.exs file
config :my_app, Repo,
  adapter: Sqlite.Ecto,
  database: "ecto_simple.sqlite3"

# In your application code
defmodule Repo do
  use Ecto.Repo,
    otp_app: :my_app,
    adapter: Sqlite.Ecto
end

defmodule Weather do
  use Ecto.Model

  schema "weather" do
    field :city     # Defaults to type :string
    field :temp_lo, :integer
    field :temp_hi, :integer
    field :prcp,    :float, default: 0.0
  end
end

defmodule Simple do
  import Ecto.Query

  def sample_query do
    query = from w in Weather,
          where: w.prcp > 0 or is_nil(w.prcp),
         select: w
    Repo.all(query)
  end
end

Usage

Add Sqlite.Ecto as a dependency in your mix.exs file.

def deps do
  [{:sqlite_ecto, "~> 0.3.0"}]
end

You should also update your applications list to include both projects:

def application do
  [applications: [:logger, :sqlite_ecto, :ecto]]
end

To use the adapter in your repo:

defmodule MyApp.Repo do
  use Ecto.Repo,
    otp_app: :my_app,
    adapter: Sqlite.Ecto
end
