xBacon

A set of validators and matchers, focusing on Brazilian needs, but general too!

Here you can find useful validations for your changeset, or just matchers if you want!

How do I use it ?

Simply import the changeset module into your model and pipe the validations on your changeset!

defmodule App.Person do
  import XBacon.Changeset.CPF

  # ....

  def changeset(model, params \\ %{}) do
    model
    |> cast(params, @fields)
    |> validate_required(@req_fields)
    |> validate_cpf
  end
end

The validators use a default field naming matching the subject being validated, for example, if you are validating CPF with validate_cpf/2 you can provide an atom as second arity if your field is not named :cpf

Installation

The package can be installed as:

1. Add xbacon to your list of dependencies in mix.exs:

```elixir
def deps do
  [{:xbacon, "~> 0.1.0"}]
end
```

2. Ensure xbacon is started before your application:

```elixir
def application do
  [applications: [:xbacon]]
end
```

xbacon's Issues

Credit card validation

CNPJ validation

RG validation

Since each state has it rules for verification, it should only verify if has only digits at a required size

CEP validation

CEP as part of an address should be validated since most of address rely on it to find all address information automatic.

The most common pattern for CEP is 000000-000, so in regex it could be [0-9]{5}[-]?[0-9]{3}.
This will allow both previous format and plain 00000000 formart
