Usage

Connection Pools

defmodule MongoPool do
  use Mongo.Pool, name: __MODULE__, adapter: Mongo.Pool.Poolboy
end

# Starts the pool named MongoPool
{:ok, _} = MongoPool.start_link(database: "test")

# Gets an enumerable cursor for the results
cursor = Mongo.find(MongoPool, "test-collection", %{})

Enum.to_list(cursor)
|> IO.inspect

APIs

Mongo.find(MongoPool, "test-collection", %{}, limit: 20)
Mongo.find(MongoPool, "test-collection", %{"field" => %{"$gt" => 0}}, limit: 20, sort: %{"field" => 1})

Mongo.insert_one(MongoPool, "test-collection", %{"field" => 10})

Mongo.insert_many(MongoPool, "test-collection", [%{"field" => 10}, %{"field" => 20}])

Mongo.delete_one(MongoPool, "test-collection", %{"field" => 10})

Mongo.delete_many(MongoPool, "test-collection", %{"field" => 10})

Pool Transactions

# Gets a pool process (conn) to run queries on
MongoPool.transaction(fn (conn) ->
  # Removes 1 result using the query
  Mongo.Connection.remove(conn, "test-collection", %{"field" => 1})

  # Removes all results using the query
  Mongo.Connection.remove(conn, "test-collection", %{"field" => 1, "otherfield" => 1}, multi: true)
end)
