TinyMCE Images...Url and Uploaded

TinyMCE is an incredibly popular text editor, but it's harder to get images working than it should be.

Everyone knows and loves the TinyMCE text editor. It has a combination of being decently easy to install, having all the features you need, and actually working that you're hard-pressed to find in a WYSIWYG editor these days. (Nerd's note: WYSIWYG stands for 'what you see is what you get' but is pronounced wuh-zee-wig.)

The documentation for the Rails TinyMCE gem is here: https://github.com/spohlenz/tinymce-rails

However, we're going to add to this a little because the main focus of this article is getting you to the point where you can upload images within your post, which is (unfortunately) a whole different can of worms entirely.

Add the Gems

To start out, you want to install the usual TinyMCE gem. You used to need a special image upload gem as well, but it's fortunately no longer necessary.

   gem 'tinymce-rails'

Run your standard bundle install and let's go.

Add the Config File

Create a config/tinymce.yml file with your desired plugins, configuration, etc.

The one I usually use looks something like this:

toolbar:
  - styleselect | bold italic underline strikethrough | indent outdent | alignleft aligncenter alignright alignjustify | blockquote | uploadimage image | link anchor | code codeformat codesample | bullist numlist checklist
  - code | undo redo
plugins:
  - code
  - image
  - link
  - lists
  - advlist
  - codesample
  - textcolor
  - uploadimage
menubar:
  - view
  - format
  - table
  - tools

Add the Javascript

Don't forget to put //= require tinymce in your application.js.

Image Uploader

Okay, this used to be way harder. Just follow this guy for the image upload-y bits: https://medium.com/@kristina.kabosiene/manual-upload-rails-6-active-storage-tinymce-5-and-aws-s3-2f139c0b5df4

This will hook it up so your uploaded images are stored in AWS S3. Which is MAGICAL.
