EctoExplorer

A small utility that uses metaprogramming to provide a neat ~>/2 macro to explore Ecto associations without having to Repo.preload/2 all the time.

Use it like this:

iex> use EctoExplorer, repo: EctoExplorer.Repo
EctoExplorer

iex> f = Repo.get_by(Flag, colors: "YBR")
%EctoExplorer.Schemas.Flag{...}

iex> f~>country.addresses[0].postal_code
"postal_code_ECU_1"

iex> f~>country.addresses[-1].postal_code
"postal_code_ECU_6"

Next steps

• Allow index access to get specific structs by a specific criteria, e.g. flag~>country.addresses[id=123] or flag~>country.addresses[city="Lisbon"]

Installation

The package can be installed by adding ecto_explorer to your list of dependencies in mix.exs:

def deps do
  [
    {:ecto_explorer, "~> 0.5.0", only: [:dev, :test]}
  ]
end

ℹ️ Notice that we're only adding it as a dependency for :dev and :test Mix environments.

🚨 Please don't use this in Production! This library is a convenience to quickly navigate complex domain models, it shouldn't ever be considered as a way to avoid thinking about how you Repo.preload/2 your associations.
