README

Crudex

A glue keeping Phoenix and Ecto together. It has the following features:

  • JSON-encoding/decoding of Ecto models
  • Dynamic virtual fields for models
  • Simplifies creation of CRUD controllers
  • User controller for login.

Crudex.Model

By using the Crudex.Model module, like this:

defmodule MyModel do
  use Crudex.Model
end

You make your model JSON-encodable using Poison. You should also use Ecto.UUID, Crudex.JSONBinary, Ecto.DateTime instead of :uuid, :binary, and :datetime in your model respectively.

The Crudex.Model also provides the following macros:

  • crudex_schema => is like schema from Ecto.Model but defines ID/foreign keys to be UUID and creates timestamps. You should use this if you want to use the CRUD controller functionalities. It also allows using the two macros below
  • hidden_field => creates a regular field which will be excluded when encoding

Example

defmodule Example.User do
  use Crudex.Model

  crudex_schema "users" do 
    field :name, :string   
    field :surname, :string   
    field :email, :string
    hidden_field :salt, Crudex.JSONBinary
    hidden_field :password, Crudex.JSONBinary
    field :role, :string
  end

  ...
end

Crudex.CrudController

Allows automatic creation of complete or partial CRUD controllers. It even supports user scoping, assuming your model has a user_id field.

It has two macros

  • crud_for => creates CRUD actions for the given model. Optionally you can specify which actions should be created.
  • defcrud => defines a single CRUD action for the given model.

Example

defmodule BookController do
  use Crudex.CrudController

  plug PlugAuth.Authentication.Token, [source: :params, param: "auth_token"]
  plug :action

  @ecto_repo MyRepo
  @user_scoped true
  crud_for(Book)
end

Assuming you have a Book model, you will get the :index, :create, :show, :update, :delete actions created for you. Since @user_scoped is set to true, all actions will only be applicable for the user currently logged in. This works best in conjunction with plug_auth.

Crudex.UserController

Provides a macro, user_controller to define a simple user controller. Access control should happen in the controller invoking this macro, using for example plug_auth. It is not very flexible for now, and is more there to show you how to do a complex controller with Crudex.

TODO

There is a lot to do, pagination and filtering is one of the first things. Tests are missing although I have tests in the projects where I use this. Documentation in the code is also missing for now.
