MongoEctoLite aims to be a simple bridge from Ecto Changesets to MongoDB.
Please note: this project is in early days and should be considered a tech preview at this point.
Almost all Phoenix examples use Ecto, and LiveView uses Changesets extensively. Unfortunately there is not an actively maintained solution for using Ecto with MongoDB.
MongoEctoLite implements a subset of Ecto.Repo functions, specifically those used by phx.gen.live and phx.gen.auth. It supports schemas with map, embeds_one, embeds_many, and schemaless.
Example:
defmodule MyCollection do
use Ecto.Schema
import Ecto.Changeset
@primary_key {:_id, :binary_id, autogenerate: false}
schema "my_collection" do
field(:name, :string)
field(:child, :map)
timestamps()
end
def changeset(item, attrs) do
item
|> cast(attrs, [:name, :child])
|> validate_required([:name, :child])
end
end
attrs = %{name: "some name", child: %{name: "some child name"}}
{:ok, my_collection} =
%MyCollection{}
|> MyCollection.changeset(attrs)
|> Repo.insert()
results = Repo.all(Schema, %{name: "some name"})
Dynamic repositories are also supported:
MyCollection.with_dynamic_repo(conn, fn ->
MyCollection.all(Schema)
end)
