FipeApi

This application is a ruby client to the Tabela Fipe Api - http://www.fipe.org.br/pt-br/indices/veiculos/. It makes use of the excellent http gem to make http requests and nokogiri to parse the response

Add this line to your application's Gemfile:

gem 'fipe_api'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fipe_api

The base class to use is a FipeApi::Vehicle. The Fipe data makes use of three Vehicles types wich are mapped to a FipeApi::Vehicle constant. The constants are:

• FipeApi::Vehicle::CAR
• FipeApi::Vehicle::MOTORCYCLE
• FipeApi::Vehicle::TRUCK

You can get all Vehicles types with:

vehicles = FipeApi::Vehicle.all

You can access the first vehicle like this:

vehicles.first.id => 1
vehicles.first.name => Car

or you can initialize an specific Vehicle type, let`s say a CAR, with:

vehicle = FipeApi::Vehicle.new(FipeApi::Vehicle::CAR, "Car")

Given a vehicle you can get all of its tables. A Table is generated each month with updated values for some vehicles. So, to get all tables you may do:

tables = vehicle.get_tables

Frequently you will be using the latest table generated, i.e. that was generated for the current month and year, to get the vehicles data. It`s possible to retrieve the latest table for an specific vehicle with:

latest_table = FipeApi::Table.latest(vehicle)

or you can get a table for an specific month and year:

table = FipeApi::Table.find_by_month_and_year(vehicle, 3, 2015) # Table from March/2015

Once you have a vehicle and a given table, you can get all of the vehicle`s Brands(Ford, Fiat, GM/Chevrolet, BMW, etc...), like so:

brands = vehicle.get_brands(table) #If you don`t pass a table, it will use the latest table for the vehicle.

You can also filter the the array by name if you want to get an specific brand:

brand = vehicle.get_brands.find{|b| b.name == 'Ford' }

Now you can retrieve all Models for an specific brand. For the Ford brand we have as examples of models: Fiesta, Fusion, Taurus, etc. Use this syntax to get all models:

models = brand.get_models(table) #If you don`t pass a table, it will use the latest table for the vehicle.

Now, let`s get the years of a model. Examples of years, for a Ford Fusion Titanium 2.0 GTDI EcoBo. Awd Aut, are: Zero KM Gasolina, 2015 Gasolina, 2014 Gasolina, 2013 Gasolina. You can get the years with:

years = model.get_years(table) #If you don`t pass a table, it will use the latest table for the vehicle.

Finally, once you have an specific year for a vehicle, it`s possible to get its price like the following:

result = year.get_result(table) #If you don`t pass a table, it will use the latest table for the vehicle.

# Result of type FipeApi::FipeResult
result.price # => R$ 124.638,00
result.authentication # => g1gj386ctbp
result.year # => FipeApi::Year(month: 7, year: 2015)
result.fuel # => Gasolina
result.query_time # => quinta-feira, 9 de julho de 2015 09:54:03
result.url #=> http://www.fipe.org.br/pt-br/indices/veiculos/carro/ford/7-2015/003376-6/32000/g/g1gj386ctbp

After checking out the repo, run bin/setup to install dependencies. Then, run bin/console for an interactive prompt that will allow you to experiment. To run the tests, use rake spec.
