PoC: GraphQL Ruby fragment caching

This example demonstrates how we can cache the response fragments in graphql-ruby.

Existing solutions only allow caching resolved values but not all the GraphQL machinery (validation, coercion, whatever).

Caching response parts (in case of Ruby, sub-Hashes) is much more efficient.

Benchmarks

1. Setup

rails new blog
cd blog
hanami new bookshelf
vim Gemfile # add `hanami`
bundle
vim bookshelf/config/environment.rb # See Note 1

Some rake tasks to help migrate Radiant (v1.1.4) sites to Refinery (v3.0.4).

Put these Ruby files in place in the respective Radiant and (new) Refinery apps
You'll need to manually bring your layouts across and adapt accordingly, as well as images, javascripts and stylesheets.
Run rake export:json in your Radiant app
Copy the resulting dump.json file into the Refinery app (or put it online somewhere - perhaps a private gist - if you're going to need to import in the production environment)
Add the salt column to your Refinery app's user model: rails g migration add_salt_to_refinery_authentication_devise_users salt:string
Run rake db:migrate in your Refinery app.
Run rake import:pages import:assets import:users in your Refinery app.
In a Rails console in your Refinery app, change your home page to have the root path. If it's the first page in the app (likely), this will do the trick: Refinery::Page.first.update_attributes :link_url => '/'

TinyMCE with file manager

This post shows how to use TinyMCE 4.1 WYSIWYG text editor in a Rails 4 application for editing content in a textarea field.

TinyMCE is a powerful online WYSIWYG editor with many plugins.

If you want to insert an image by selecting it from images stored on server or upload an image to server, then you need to have a file manager with tinyMCE. TinyMCE comes with a file manager which is not free.

elFinder is an open-source file manager which can be easily integrated with tinyMCE 4.1.

Fix 'scoped' error for Rails 4

error: undefined method 'scoped' solution:

# config/initializers/scoped.rb
class ActiveRecord::Base
  # do things the modern way and silence Rails 4 deprecation warnings
 def self.scoped(options=nil)

options ? where(nil).apply_finder_options(options, true) : where(nil)

Elasticsearch: updating the mappings and settings of an existing index

Note: This was written using elasticsearch 0.9.

Elasticsearch will automatically create an index (with basic settings and mappings) for you if you post a first document:

$ curl -X POST 'http://localhost:9200/thegame/weapons/1' -d \
'{
  "_id": 1,

	FROM ruby:3.0-alpine

	RUN apk add --no-cache --update \
	ack \
	bash \
	build-base \
	curl \
	git \
	htop \
	less \

	require 'logger'
	require 'byebug'

	require 'dry/monads'
	require 'dry/monads/do'
	require 'dry/matcher/result_matcher'

	module Dry
	module Transaction
	module Steps

	class FileUploadComponent extends Component{
	upload(){
	this.props.mutate({
	variables: {
	id,
	avatar: this.inputFile.files[0] //this is how you send file
	}
	}).
	then(({data}) => {
	console.log(data)
