How to work Phoenix Framework with Mongodb?

I am trying to use phoenix framework with mongodb as database so i run the following command to get started

mix phoenix.new helloworld --database mongodb

My mix.exs file looks like this:

defp deps do
  [{:phoenix, "~> 1.2.1"},
   {:phoenix_pubsub, "~> 1.0"},
   {:phoenix_ecto, "~> 3.0"},
   {:mongodb_ecto, ">= 0.0.0"},
   {:phoenix_html, "~> 2.6"},
   {:phoenix_live_reload, "~> 1.0", only: :dev},
   {:gettext, "~> 0.11"},
   {:cowboy, "~> 1.0"}]
end

but when I run mix deps.get, I get the following error:

Failed to use "ecto" (versions 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5, 2.0.6, 2.1.0, 2.1.1, 2.1.2, 2.1.3, 2.1.4) because

** (Mix) Hex dependency resolution failed, relax the version requirements of your dependencies or unlock them (by using mix deps.update or mix deps.unlock). If you are unable to resolve the conflicts you can try overriding with {:dependency, "~> 1.0", override: true}

How do I get started?

The problem here is that mongodb_ecto hasn't been updated in quite a while and hence doesn't support the newer versions of Ecto (v2.0 and above) which is what Phoenix is currently using. This causes mix deps.get to fail since it cannot resolve the dependencies.

One solution here is to directly use the MongoDB driver for Elixir instead of mongodb_ecto and configure it to work with Ecto in your Phoenix application. Here is a blog post that explains how you can do that:

Phoenix with Ecto and MongoDB

There's also another library that offers MongoDB support for Ecto 2, but it's still listed as beta on the project's github repository. You can check for yourself if it meets your usage criteria:
