# :octopus: FakerElixir

[![Inline docs](http://inch-ci.org/github/GesJeremie/faker-elixir.svg?branch=master&style=flat-square)](http://inch-ci.org/github/GesJeremie/faker-elixir)

FakerElixir is an Elixir package that **generates fake data** for you. Whether you need to **seed** your database, create **factories** for your project, FakerElixir is here for you :punch:.

If you like this library ... you could star it :star2:

## Installation

Can't wait to generate some fake data ? Follow the steps:

1. Add `faker_elixir_octopus` to your list of dependencies in `mix.exs`:
  
```elixir
def deps do
  [{:faker_elixir_octopus, "~> 1.0.0",  only: [:dev, :test]}]
end
```

2. Ensure `faker_elixir_octopus` is started before your application:

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

**Note:** This step can be skipped if you are using Elixir 1.4+ (see [CHANGELOG#application-inference](https://github.com/elixir-lang/elixir/blob/v1.4/CHANGELOG.md#application-inference)).

3. Run in the root of your project:

```
$ mix deps.get
```

4. Faker Elixir is now a part of your application and ready to use!

## Usage

Since I'm quite sure you are using Phoenix, I will show you a basic example:

```elixir
defmodule Zombie.AwesomeController do
  use Zombie.Web, :controller

def index(conn, _params) do
    text conn, FakerElixir.Helper.pick(["zombie", "human"])
  end
end
```

Now if you keep refreshing your browser, the value should change. Awesome, you just understood how to use Faker :clap:.

#### :speech_balloon: "Sounds cool, but what about that ```FakerElixir``` namespace, it's quite boring to write that everytime :confused:"

You are right, you could use ```alias``` of elixir:

```elixir
defmodule Zombie.AwesomeController do
  use Zombie.Web, :controller

alias FakerElixir, as: Faker

def index(conn, _params) do
    text conn, Faker.Helper.pick(["zombie", "human"])
  end
end
```

#### :speech_balloon: "I followed the steps to install the package, but it doesn't work :angry: !!"

I guess you have an error similar to  ```something .... Store.has?() ..... something```. Well you just forgot to add ```:faker_elixir_octopus```:

```elixir
# mix.exs file

def application do
    [mod: {Test, []},
     applications: [:phoenix, :phoenix_html, :cowboy, :logger, :gettext,
                    :phoenix_ecto, :postgrex, :faker_elixir_octopus]] # <---- here
  end

```

## Locales

### General
---
The default locale used by FakerElixir is ```:en```. Right now only 4 locales are available: ```:fr```, ```:en```, ```:es```, ```:it```.

If you set a different locale, FakerElixir will just fallback to ```:en``` (If you didn't provide a custom locale)

**Note:** Keep in mind you can set the locale at the runtime, the locale set will keep his state until you set another locale.

#### Basic example
```elixir
FakerElixir.set_locale(:en) # :ok
FakerElixir.Address.city # "Baltimore"

FakerElixir.set_locale(:fr) # :ok
FakerElixir.Address.city # "Issy-les-Moulineaux"

FakerElixir.set_locale(:es) # :ok
FakerElixir.get_locale # :es
```

#### Phoenix Example
```elixir
defmodule Zombie.AwesomeController do
  use Zombie.Web, :controller
  alias FakerElixir, as: Faker

def index(conn, _params) do

Faker.set_locale(:en)
    city_en = Faker.Address.city

Faker.set_locale(:fr)
    city_fr = Faker.Address.city

text conn, "#{city_en} / #{city_fr}"
  end
end

# Will produce something like: Charlotte / Courbevoie
```

### Custom locale
---
Since this package is quite new we don't have enough locales out of the box. It could be possible you don't like the data provided too. That's why we let you the possibility to define / update the data !

#### Add a new locale
---
Let's say you are spanish and you want to create the ``:es`` locale, you just need to define a new module in your elixir / mix project:

```elixir
# locales/faker_elixir/es.ex
# It doesn't matter where you define your module tho.

defmodule FakerElixir.LocalesCustom.Es do

# Let's "localize" the cities
  @cities ["Barcelona", "Madrid", "La Jonquera"]

def cities, do: cities

end
```

Now when you will set the locale ```:es```, FakerElixir will pick your data:

```elixir
defmodule Test do

alias FakerElixir, as: Faker

def try do
    Faker.set_locale(:es)
    Faker.Address.city # Barcelona
  end

end
```

#### Edit a locale
---
Let's say you want to update the locale ```:fr``` for the method ```FakerElixir.Address.secondary_address```:

```elixir
# locales/faker_elixir/fr.ex
# It doesn't matter where you define your module tho.

defmodule FakerElixir.LocalesCustom.Fr do

@secondary_addresses ["Sonnette. ##"]

def secondary_addresses, do: @secondary_addresses

end
```

Now when you will set the locale ```:fr```, FakerElixir will pick your data:

```elixir
defmodule Test do

alias FakerElixir, as: Faker

def try do
    Faker.set_locale(:fr)
    Faker.Address.secondary_address # Sonnette. 12
  end

end
```

#### Skeleton
---
The default skeleton for a locale is available here: [Skeleton](https://github.com/GesJeremie/faker-elixir/blob/master/lib/faker_elixir/locales/en.ex)

## Customisation

#### :speech_balloon: "Hey dude, your package is "great" but you forgot that, that and ... that, whaddup ? :sunglasses:"

Well, depending the domain of your application, sure you will need some other fake data. That's why ```FakerElixir``` provides some useful things such as: ```FakerElixir.get_locale/0``` and the ```FakerElixir.Helper``` module.

You could create your own module inside your application:

```elixir
defmodule FakerElixir.Custom do

@pokemons_en ["Charizard", "Bulbasaur", "Charmander"]
  @pokemons_fr ["Dracaufeu", "Bulbizarre", "Salameche"]

def pokemon do
    locale = FakerElixir.get_locale

case locale do
      :fr ->
        FakerElixir.Helper.pick(@pokemons_fr)

_ ->
        FakerElixir.Helper.pick(@pokemons_en)
    end
  end

end
```

... and just call your module! ```iex> FakerElixir.Custom.pokemon```

Hope it helps :yum:
