SF_Movie

I made a prototype for one of the shared projects SF Movies

Project Requirements

Create a service that shows on a map where movies have been filmed in San Francisco. The user should be able to filter the view using autocompletion search.

Puplic API used

The data is available on Film Locations, the API returns around 1500 of data-objects in this structure:

{
  "title",
  "release_year",
  "locations":"2550165",
  "fun_facts":"2419733",
  "production_company":"6331",
  "distributor":"1564"
}

Returned data is full of duplicate rows.

Other APIs

• geocoder gem to retrieve location latitude and longitude
• Google Maps to show locations on maps

Technologies

• Ruby 2.5.1
• Rails 5.0.1
• Bundler 1.16.3
• Postgre gem
• Heroku for deployment

Installing

Install all above technologies

git clone $repo
cd sf-movies
rake db:migrate
rake filling_data:read_data_from_Socrata_SF_Data
rails s

rake filling_data:read_data_from_Socrata_SF_Data command to call File Locations API and fill Postgre database

Testing

I am using the following gems:

• rspec-rails
• factory_bot_rails
• shoulda-matchers
• faker
• database_cleaner

To run tests

rspec

What to test

• models
• controllers
• I skipped views testing, I thought it will be out of scope of backend position

Deployment

Heroku seems fast and free to deploy simple rails project like this one. I used Heroku and connected it with the Github repo. Every push to this repo start deployment on Heroku

Servers

• only for production https://stormy-shelf-15213.herokuapp.com

CI for running tests

It could be added simply to Heroku pipeline and could be connected to Github pushes, but I didn't add that as it costs money

Scaling

I suggest using AWS to scale this app as follow:

• create CodeDeploy application connected to my Github Repo and also add Deployment configuration
• Create ASG with a criteria for scaling the EC2 instances with user data containing all packages needed by EC2 instances to run rails application
• Add required scripts by EC2 instances to the repo

I didn't do that as I afraid to exceeds free-tier limits.

How to use front-end

• API reutrns some locations outside San Francasco, I filtered out these locations
• visit https://stormy-shelf-15213.herokuapp.com or https://stormy-shelf-15213.herokuapp.com/locations/index to show UI for the application
• Tha page contains a map displaying all locations
• click on any location to see list of movies regarding to this locations
• the page also contains list of filteration boxes with (and) condition which means it is better to search with one attribute at a time to find results
• all text fileds support autocomplete
• after add some values to the text fileds click on search

My code

I used Rails with alot of built-in code, to identify code written by me, ignore the first commit

Skipped

I skipped some points as I don't have enough time:

• proper integration testing
• Production-readiness: like monitoring, logging and proper error handling
