du7f

du7f is a simple web-based polling tool using the Ruby on Rails framework.

See it in Action

An instance is running over there du7f.koalatux.ch.

Start Development

For development you need a recent ruby version, I recommend rbenv for managing ruby versions. Make sure to install the version of ruby mentioned in the .ruby-version file.

Make sure you have the bundler gem installed

gem install bundler

Then install all dependencies using bundler by running the following command in the top level directory of du7f

bundle install

Create and initialize the database

bundle exec rake db:setup

Then you may start a local development instance of du7f and point your browser to http://localhost:3000/

bundle exec rails server

Or run all tests:

bundle exec rake test

Database

du7f has only been tested using SQLite as a database. But might work as well with others.

Source Code

The source code of du7f is available at GitHub.

Note about the SQLite adapter

If you are using the SQLite adapter and are upgrading from a du7f version which uses a Rails version before 5.2, you need to convert booleans from strings to integers in your database, because booleans as strings is depraced with Rails 5.2. You might use the provided rake task.

RAILS_ENV=production bundle exec rake sqlite_boolean_as_integer:convert_to_int
