Dogstagram

Dogstagram is a web application for dog selfies inspired by Instagram built using Ruby on Rails and React.js.

Dogstagram allows users to:

• Create an account
• Log in / Log out
• Follow Users
• Create, Read, and Delete Posts
• Like Posts
• Create, Read, and Delete Comments

###Custom made user authentication I overwrote the password= method using the BCrypt gem in the user model to store a hashed and salted password:

def password=(password)
  @password = password
  self.password_digest = BCrypt::Password.create(password)
end

Incoming passwords can then be compared against the stored password hash to see if the password is correct

def is_password?(password)
  BCrypt::Password.new(self.password_digest).is_password?(password)
end

A users session is then stored as a session token to remember a user is signed in at a specific computer

def reset_token!
  self.session_token = generate_session_token
  self.save
  self.session_token
end

I implement a check for duplicate session tokens for the security of all my users' accounts. While it is uncommon for the same token to be generated twice, it becomes more likely to happen as the user base grows.

def generate_session_token
  token = SecureRandom.urlsafe_base64(16)

  while User.exists?(session_token: token)
    token = SecureRandom.urlsafe_base64(16)
  end

  token
end

###Feed based on user follows The feed only displays posts from users that the current user is following, with most recent first

def index
  following_ids = "SELECT followed_id FROM relationships
                   WHERE  follower_id = :user_id"

  @posts = Post.includes(:user, :likes, comments: [:user])
    .where("user_id IN (#{following_ids})
            OR user_id = :user_id", user_id: current_user.id)
end
