Ruby (on Rails + Heroku) framework for interaction with custom data

Is there any recommended (by you) CMS/CMF for Ruby, that allows simple interaction with custom data? Have you got any recommended ap开发者_StackOverflow中文版proaches? The data won't be too much complicated. Heroku compliance is a must.

One other thing. It came out, that I have got little time to provide a demo. Are the proposed frameworks real time-savers, including time required to learn the framework?

If I am understanding your question correctly, I would recommend RailsAdminor Jeweli. There is an extensive list here

Will Locomotive CMS cut it for you? It has custom content types and fields. And it works with Heroku. Since it is a fully fledged Rails engine, you can just set it up and have it running within minutes.

As no answer was submitted after update - just take your time, learn RoR well and write the code you need. Ultimately, I used no external framework.
