Add bulk import functionality to Rails Active Record (add this file to config/initializers, call <model>.import!(array-of-record-hashes))
class ActiveRecord::Base
def self.import!(record_list)
raise ArgumentError "record_list not an Array of Hashes" unless record_list.is_a?(Array) && record_list.all? {|rec| rec.is_a? Hash }
return record_list if record_list.empty?
(1..record_list.count).step(1000).each do |start|
key_list, value_list = convert_record_list(record_list[start-1..start+999])
sql = "INSERT INTO #{self.table_name} (#{key_list.join(", ")}) VALUES #{value_list.map {|rec| "(#{rec.join(", ")})" }.join(" ,")}"
self.connection.insert_sql(sql)

Bootstrap 4 in Phoenix Framework using Webpack
// We need to import the CSS so that webpack will load it.
// The MiniCssExtractPlugin is used to separate it out into
// its own CSS file.
import css from "../css/app.scss"
// webpack automatically bundles all modules in your
// entry points. Those entry points can be configured
// in "webpack.config.js".
