Catarse Build Status

Oficial repository changed!

Our new address is https://github.com/catarse/catarse

An open source crowdfunding platform for creative projects

Welcome to Catarse's source code repository. Our goal with opening the source code is to stimulate the creation of a community of developers around a high-quality crowdfunding platform.

You can see the software in action in http://catarse.me.

Getting started


This software was first created as Brazil's first crowdfunding platform. Thus, it was first made in Portuguese and with a brazilian payment gateway. We are now internationalizing it, and already have a good support for the english language and for paypal express checkout. See below the Payment gateways section for more information about integrating Catarse with a payment system of your choice. If you want to join us in this effort, please feel free to fork the repository and send us a pull request with your changes. If you have any doubt, please join our Google Group at http://groups.google.com/group/catarse-dev and we will help you.


We hope to support a lot of languages in the future. So we are willing to accept pull requests with translations to other languages. Here's a small guide to translate Catarse to your language in a way that we can integrate your translation in the main repository:

Thanks a lot to Daniel Walmsley, from http://purpose.com, for starting the internationalization and beginning the english translation.

Payment gateways

Currently, we support MoIP and PayPal through our payment engines. Payment engines are extensions to Catarse that implement a specific payment gateway logic. The two current working engines are:

  • MoIP
  • PayPal

If you have created a different payment engine to Catarse please contact us so we can link your engine here. If you want to create a payment engine please join our mailing list at http://groups.google.com/group/catarse-dev

Here are some tips to get things started:

How to contribute with code

Before contributing, take a look at our Roadmap (https://www.pivotaltracker.com/projects/427075) and discuss your plans in our mailing list (http://groups.google.com/group/catarse-dev).

Our pivotal is concerned with user visible features using user stories. But we do have some features not visible to users that are planned such as:

  • Turn Catarse into a Rails Engine with customizable views.
  • Turn Backer model into a finite state machine using the state_machine gem as we did with the Project model.
  • Improve the payments engine isolation providing a clear API to integrate new payment engines in the backer review page.
  • Make a installer script to guide users through initial Catarse configuration.

Currently, a lot of functionality is not tested. If you don't know how to start contributing, please help us regaining control over the code and write a few tests for us! Any doubt, please join our Google Group at http://groups.google.com/group/catarse-dev and we will help you out.

After that, just fork the project, change what you want, and send us a pull request.

Coding style

  • We prefer the {foo: 'bar'} over {:foo => 'bar'}
  • We prefer the ->(foo){ bar(foo) } over lambda{|foo| bar(foo) }

Best practices (or how to get your pull request accepted faster)

We use RSpec and Steak for the tests, and the best practices are:

  • Create one acceptance tests for each scenario of the feature you are trying to implement.
  • Create model and controller tests to keep 100% of code coverage at least in the new parts that you are writing.
  • Feel free to add specs to the code that is already in the repository without the proper coverage ;)
  • Try to isolate models from controllers as best as you can.
  • Regard the existing tests for a style guide, we try to use implicit spec subjects and lazy evaluation as often as we can.
