Build a forum web application using Ruby on Rails

Hello, I'm looking for someone to build me a simple forum web application. - Using Ruby on Rails. - No styling (css) necessary. The basic structure of the forum would be as follows/or similar. Users • Has_many :forum_threads • Has_many :forum_posts ForumThread • Belongs_to :user • Has_many :forum_posts ForumPost • Belongs_to: user • Belongs_to :forum thread ----- - Users need to be able to create accounts and sign in and out with 'devise' gem. - Users need to be able to create, edit and delete their own posts. - Users need to be able to add comments on posts (with markdown or something similar) - It would also be great to have categories. To categorise forum thread topics - If possible include a search function, so users can search for posts/threads via keywords.
