NebulexEcto v0.1.0 NebulexEcto View Source
NebulexEcto
provides the module NebulexEcto.Repo
, which is the wrapper
on top of Nebulex.Cache
and Ecto.Repo
.
Cacheable Repo
Suppose you have an Ecto repo and a Nebulex cache separately:
defmodule MyApp.Cache do
use Nebulex.Cache,
otp_app: :my_app,
adapter: Nebulex.Adapters.Local
end
defmodule MyApp.Repo do
use Ecto.Repo,
otp_app: :my_app,
adapter: Ecto.Adapters.Postgres
end
The idea is to encapsulate both in a single module using NebulexEcto.Repo
,
like so:
defmodule MyApp.CacheableRepo do
use NebulexEcto.Repo,
cache: MyApp.Cache,
repo: MyApp.Repo
end
Configuration would be like this:
config :my_app, MyApp.Cache,
gc_interval: 3600
config :my_app, MyApp.Repo,
database: "ecto_simple",
username: "postgres",
password: "postgres",
hostname: "localhost"
Now we can use MyApp.CacheableRepo
as a regular Ecto repo, of course,
there are some constraints, NebulexEcto.Repo
only provides some of
the Ecto.Repo
functions (the basic ones – get, get_by, insert, update,
delete, etc.), please check them out before.
Usage example:
schema = %MyApp.MySchema{x: "abc"}
{:ok, schema} = MyApp.CacheableRepo.insert(schema)
MyApp.CacheableRepo.get!(MyApp.MySchema, schema.id)
MyApp.CacheableRepo.get_by!(MyApp.MySchema, [id: schema.id])
changeset = Ecto.Changeset.change schema, x: "New"
{:ok, schema} = MyApp.CacheableRepo.update(changeset)
MyApp.CacheableRepo.delete(schema)
