Basic Usage

This is a super easy way to ensure that timestamps/datetimes etc render correctly according to the timezone that the object is in. In our usage we have a time_zone attribute on our models that stores the time zone in a format that we can find with active support. Example American Samoa, for more examples run bundle exec rake time:zones:all in your rails project.

We weren't aiming to display the datetime in a format relative to the user, but rather just display that the time was in X time zone

# lets assume we have an attribute called start_time

By default Rails wraps form errors in a div with the class field_with_errors.

There are 2 ways to disable this.

First way is in the application.rb environment file (doesn't make sense just to disable it on a specific environment?):

# config/application.rb

module ApplicationName

us-east-2
us-east-1
us-west-1
us-west-2
ap-east-1
ap-south-1
ap-northeast-3
ap-northeast-2
ap-southeast-1
ap-southeast-2

	# app/helpers/application_helper.rb
	module ApplicationHelper
	# active_storage_item could be a blob or variant object
	def proxy_url(active_storage_item, options = {})
	options.merge!(host: ENV['ASSETS_HOST']) if ENV['ASSETS_HOST'].present?

	# proxy: 'true' allows you to stil have the original functionality while
	# being able to proxy through a CDN. You've got to ensure that your CDN
	# forwards this param otherwise active storage will always do the default
	# behavior which is a redirect to the service.

	# app/models/application_record.rb

	class ApplicationRecord < ActiveRecord::Base
	# Didn't change #update_column because it uses #update_columns under the hood.
	def update_columns(attrs)
	new_attrs = attrs.symbolize_keys
	new_attrs[:updated_at] \|\|= Time.current if self.class.column_names.include?('updated_at')
	super(new_attrs)
	end

	def dot_to_hash(value)
	return value unless value.is_a?(Hash)
	value.deep_stringify_keys.each_with_object({}) do \|(k,v), result\|
	root, child = k.split('.')
	if child
	result[root] \|\|= {}
	result[root][child] = dot_to_hash(v)
	else
	result[root] = dot_to_hash(v)
	end
