Updating the API

[CheezItMan]

Looking at this, I updated the API to a newer version of Rails & Ruby, and added Dan's Cors test and moved it toward Postgresql.

Still not done, but putting this PR up for review to date

Finished:

• Figure out what is wrong with checkin logic
• Update Rails version and fix security vulnerabilities
• Switch to Postgresql
• Tested deployment to: https://frozen-woodland-27192.herokuapp.com

Yet to do:

• Add travis CI
• Take out the assertions and move toward spec-style testing

Looks good. I'm not sure why this upgrade to 5.2 didn't involve the new secrets.yml.enc file, as we've seen with other projects being upgraded.

However, everything seems to run and be seeded fine once the MovieDB API key is setup (we should update the README to mention that probably).

Also, we should try to get this deployed through Travis. I haven't setup any projects with that, so you should probably check with Dan.

No Travis. We don't deploy this API, the students fork it and hack on it themselves. If they deploy they'll do it manually.

Reading the changes this looks good, though I have not run the app. I have two things:

• Looks like there are tests for checkin - can you confirm that these were failing before and now pass?
• Remove the travis file, since we don't deploy this one ourselves.

Then it should be good to merge.

Whoops I forgot we have a deployed demo of this! Ignore my earlier comments about Travis

[droberts-sea]

You can run travis setup heroku --force and follow the prompts to set this up.

@droberts-ada I've added a test to prevent the check-in bug from reoccuring. It involved the fact that Checking out a movie left returned as nil and check-in required it to be false. So I've got Rental to default returned to false.
