Rails AWS Configuration

Trying to figure out how to use the carrierwave gem with rails (on Heroku) to upload files to AWS turned out to be a difficult task. Most of the problems I ran into had nothing to do with code but how permissions were set up on my Amazon S3 bucket. My carrierwave.rb initializer looked like this:

Sinatra Heroku Deployment Issues

I created a simple website using the Ruby based Sinatra framework for my electronic music project. I developed it around the same time I was learning the framework at Flatiron School. To get started I copy pasted a project that was working and used it as a template for my site. Everything was fine when I first deployed it to Heroku. At that time I embedded an iframe to display my upcoming concerts. I always hated not being able to control the CSS of the iframe in an easy manner. I created a hack to try an interject some css in the widget:

React Frontend Rails Backend Architecture

For my final project for Flatiron School I created a website with a Rails Backend and a React Frontend. I decided to make a site that queries and Some bands I know use different services so instead of visiting two different sites I wanted have the results in a centralized location. Eventually I want to add Facebook events in another column. I guess you could say my idea is like the version of finding concerts.

Rails API w/ Javascript

Using the Active Model Serializers gem and jquery’s ajax methods I was able to add some extra functionality to my Rails app. The site lets users upload electronic music instruments (a ‘patch’) and I wanted to add comments to the patches show page without refreshing the page . Along with adding comments I wanted to add some pagination to the patches index page so users can scroll through recent uploads.
