Built using Ruby on Rails for backend, Bootstrap for a fully-responsive experience, PostgreSQL for database, and Rspec for all testing, Not Reddit provides a simple yet overall satisfying environment for users to discuss a range of topics. While Not Reddit may be navigated by guests, for the best experience, an account should be created. This provides the ability to create new posts, comment, upvote and downvote, favorite and follow posts receiving email notifications when another user comments, maintain a profile, as well as a few other features. In this post, we will explore the site page by page.

The app is deployed on Heroku and the source code is available on GitHub.

Home Page

A user is greeted by Not Reddit’s welcome page, allowing a user to sign in or sign up. The welcome page is representative of Not Reddit’s design - simple yet powerful - allowing users to focus on posting links, upvoting and downvoting, and getting into discussions and debates with other users. The page also boasts the site’s impressive accomplishments such as ending world hunger and poverty minutes after being launched. It also has been shown to make people significantly better looking in the laboratory. Thanks Not Reddit.

Topics Page

The topics page is viewable to any user, though only admin users can create new topics. This was intentional, in order to keep topics focused and prevent redundancy. Each topic is followed by a short description, allowing users to get an idea of what might be discussed.

When a topic is selected, the user is shown a more detailed view of the topic as well as all its associated posts. Posts are sorted by an algorithm based on number of votes and age of the post, keeping the feed fresh, yet populated with popular content.

Posts Page

Posts are also viewable to any user, however only a user who is logged in may comment, vote, or favorite the post. Any user who has favorited a post will receive email notifications via SendGrid when a new comment is posted. The owner of a post may delete the post, while the owner of a comment may delete their own comments. An admin can do whatever they want so don’t piss them off, bro.

User Profile

Gettin trolled? Hop on over to their profile page to see what they’ve been up to. User’s with gravatar will have an image displayed along with the number of posts and comments they’ve made. All posts, comments, and favorited posts are also displayed chronologically on every user’s profile. This helps users stay in touch and discuss more with similar-minded people (as well as avoid those they don’t like).

Privacy, Security, and Technical Junk

Private Topics
Don’t want your employer (or your mom) to find out what you’ve been doing on Not Reddit? No problem, just make a your topic private. This cool feature hides the topic from all guest users, eliminating the threat of an employer or your mother stumbling on your discussion. Piece of cake.

Thou Shall Not Edit Another User’s Posts
Keeping users or anyone else from editing information they shouldn’t is taken seriously here at Not Reddit. Private functions were written and used in conjunction with rails methods such as before_action to authorize users and force login before allowing users to access any private page or update information. Cross-site request forgery, a type of hack which exploits a user who is already logged in, is also guarded against using Rail’s built-in protect_from_forgery method.

Stong Parameters
Sometimes evil people might try to manipulate data they shouldn’t via mass assignment. For instance, the hacker might input


creating a user which is also an admin. Rails has a built-in way to handle this: Strong parameters. In each controller, it was specified which parameters are allowed to be passed in on any given page, eliminating the option to manipulate restricted data. For example, on the sign up page, a user may only input their name, email, password, and password confirmation. Checkmate hacker.

Concluding Remarks

While simple, Not Reddit securely and robustly allows users to interact via posts, comments, and voting. In the future, I would like to add some more searching and filtering features to the site. For example, currently, all of a topic’s posts are indexed according to an algorithm based on post date and rating. For starters, listing all posts for a topic will become slow and cumbersome to browse as the number of posts grows. Pagnition or something similar should be used instead. Building on that, a user should be able to search both topics and posts, as well as comments. Advanced search methods, potentially ones using AJAX, would be a great addition to the site.

Additionally, the site could use more robust CSS. As a disclaimer, the site is fully responsive and looks acceptable on any device, whether smartphone or computer. That being said, sometimes when the window is resized, the layout is subpar. Certain elements could be tweaked in size and position to give a more aesthetic feel. However, the focus of this project was more on backend and the styling remained quite basic.
