Crudry is an elixir library for DRYing CRUD of Phoenix Contexts and Absinthe Resolvers.
It also provides a simple middleware for translating changeset errors into readable messages.
Documentation can be found at https://hexdocs.pm/crudry.
The changelog can be found at the Releases page.
The package can be installed by adding crudry
to your list of dependencies in mix.exs
:
def deps do
[
{:crudry, "~> 2.4.0"},
]
end
To generate CRUD functions for a given schema in your context, simply do:
defmodule MyApp.MyContext do
alias MyApp.Repo
require Crudry.Context
Crudry.Context.generate_functions MyApp.MySchema
end
To see the functions that are generated and custom options, refer to the Crudry.Context docs.
With the context all set up, the resolver is ready to be generated:
defmodule MyApp.MyResolver do
alias MyApp.Repo
require Crudry.Resolver
Crudry.Resolver.generate_functions MyApp.MyContext, MyApp.MySchema
end
To see the functions that are generated and custom options, refer to the Crudry.Resolver docs.
Absinthe Middleware to translate errors and changeset errors into human readable messages. It support nested changeset errors and internationalization, using Gettext.
To handle errors for a field, add it after the resolve, using middleware/2
:
alias Crudry.Middlewares.TranslateErrors
field :create_user, :user do
arg :params, non_null(:user_params)
resolve &UsersResolver.create_user/2
middleware TranslateErrors
end
To handle errors for all fields, use middleware/3:
alias Crudry.Middlewares.TranslateErrors
def middleware(middleware, _field, _object) do
middleware ++ [TranslateErrors]
end
Crudry.Translator
is used by default to translate error messages to the default locale en
. You can also use your own Gettext module by adding it to your Absinthe's schema context/1
function:
def context(context) do
Map.put(context, :translator, MyAppWeb.Gettext)
end
Or just override the default locale in your Context Plug:
def call(conn, _) do
Absinthe.Plug.put_options(conn, context: %{locale: "pt_BR"})
end
Refer to the TranslateErrors docs for more information.
