WDI Progress Update - Trendmyhunch Extras, Google Analytics Client Authentication using Service Account and OAuth

Challenges:

• Google Analytics Client, Google's API Developers Console (connected!)
• Google Maps Coordinate API (yet to attempt)
• Extras add to My Website: Trendmyhunch
• Collapsing Menu
• Anchors
• Select / Unselect All
• Feedback form (failed on heroku push, stuck on whether i need https://devcenter.heroku.com/articles/sendgrid#ruby-rails)
• Troubles #1 tried Sample Contact Form on Github, Mailgun and associated documentation, etc (unable to use free SendGrid due to past personal income issues), might have revert back to PHP! Yikes!!

• Authentication with Google Analytics Client using Service Account and OAuth! (noted the importance of using the correct 8 digit number after the letter 'p' in the URL when in the Analytics Account Settings of the correct App!! didn't realise this initially and was getting error 403)
• Troubles #2 - Can't upload to Github to mirror pushes to Heroku! Bugger...
• Important Note: Gem Garb could have saved me a lot of time connecting to Google Analytics! 
• Played around with dashing, puma server, rufus scheduler, and redis, and rendered my heroku site useless (site still works on local server though...)  ----> discovered that the reason it wasn't working on Heroku was because there  were remnance of Dash (which I wasn't using). the error was only exposed when i ran "rails console production". to solve the issue i just opened the /app/jobs/sample.rb file and commented the whole file.

WDI Progress Update - Production, Bootstrap, CSV migrations

Challenges:

• App exploded when tried to install bootstrap, used Heroku clone to recover
• Searching databases and filtering selections

require 'fileutils'require 'csv' 

class AddIdeaData < ActiveRecord::Migration
  def up
filepath = Rails.root.join("ideas.csv")
# locate the csv file in your /public folder if File.exist?(filepath) CSV.foreach(filepath)do |col| Idea.create(:name => col[0].to_s, :description => col[1].to_s, :author => col[6].to_s, :url => col[7].to_s, :country => col[8].to_s) end else  raise "No file exists with name: #{filepath}" end  end
  def down   Idea.all.destroy # only with team permission  end
end
