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:
