Implement tags and filtering by tags in our rails application

In our rails application we enable users to submit multiple types of feedback in a project. Whenever a user submits an issue, we would like the user to have the ability to tag that issue. When the user views issues, we want them to be able to filter by those tags. Your tasks are as follows: - Create new model for tags or make use of our existing model for tags. - Allow users to choose one or multiple tags. Allow easy creation of tags from within the field that they’re typing in. - In the issues index page create a new filter that allows the user to choose a tag to filter the list of issues. Please include what your approach would be to implementing this addition. Skills: You must be familiar with ruby and rails development. Must be familiar with either cucumber and/or rspec testing frameworks as we require tests to be created to prove that the features work. This is a small project that will help us get this needed functionality into our web application. This project is also a way for us to build a relationship for future work with the accepted candidate. This will get you familiar with our web application and open up the way for future ongoing work with us. Background on us: We are a start up that's building tools for information organization, feedback, and collaboration in the enterprise. Technical details: We're using rails 3.2 and jquery. Couchdb is the database that we're using. Upon acceptance of the project we require an IP agreement be electronically signed.
