EctoPress(Docs) is a library that will generate your context functions at compile time with a minimal amount of configuration, and just enough customizability.
Very much inspired by EctoResource.
The main difference is that EctoPress defines a ResourceProvider behaviour that you can implement and set to customize how each callback functions.
This is still an early draft so there's likely to be rough edges, especially in the documentation. The DSL and/or behaviour may change as certain things become clearer but the goal is to change it as infrequently as possible, iterating towards a very stable behaviour definition.
Most likely will work with earlier versions of Elixir but I've only tested down to 1.15. If you need it to work with an earlier version, feel free to fork and test locally. I'd be happy to push the version down to be as compatible as possible.
See examples/ for a more complete demonstration.
defmodule MyApp.CustomResourceProvider do
use EctoPress.BaseResourceProvider
def list(repo, schema, clauses, opts) do
# Assuming you use a pattern where all your schemas have a `base_query` function.
query =
schema.base_query()
super(repo, query, clauses, opts)
end
end
defmodule MyApp.MyContext do
# If no provider is specified, will use `EctoPress.BaseResourceProvider`
use EctoPress, repo: MyApp.Repo, resource_provider: MyApp.CustomResourceProvider
resource User, MyApp.User
# Resources can also be customized individually. (CustomResourceProvider is redundant in this case.)
resource Post, MyApp.Post, plural: "articles", only: [:list, :get], resource_provider: MyApp.CustomResourceProvider
