# Blog Demo Application with Summernote 8 WYSIWYG Web Editor Lucius Choi, May 25, 2016 Requirements: - Ruby 2.3.1 - Rails 5.0.0.rc1 - Summernote-rails v In `Gemfile`, you will need the following gems. ```ruby gem 'bootstrap-sass' gem "bootstrap_flash_messages", "~> 1.0.1" gem 'font-awesome-sass' gem 'summernote-rails', '' gem 'codemirror-rails' gem 'simple_form' gem 'paperclip' ``` You may rename application.css to application.scss, and so, `app/assets/stylesheets/application.scss` will look like this: ```scss @import "bootstrap"; @import "scaffolds"; @import "font-awesome-sprockets"; @import "font-awesome"; @import "codemirror"; @import "codemirror/themes/monokai"; @import "summernote"; @import "posts" ``` Main important scripts on summernote can be written in `app/assets/javaScripts/` or any other coffeescript file. ```coffeescript sendFile = (file, toSummernote) -> data = new FormData data.append 'upload[image]', file $.ajax data: data type: 'POST' url: '/uploads' cache: false contentType: false processData: false success: (data) -> console.log 'file uploading...' + data.url.split("?")[0] toSummernote.summernote "insertImage", data.url deleteFile = (file) -> parser = document.createElement('a') parser.href = file file_name = parser.pathname r = confirm("Would you like to delete the uploaded image file?") if r == true $.ajax url: '/delete_file' type: 'DELETE' data: file_name: file_name success: (data) -> console.log "file deleting..." + data.deleted_file # delete imageNode return error: -> console.log "errors on file deletion" # do something return return # For Rails 5 (Turbolinks 5) page:load becomes turbolinks:load and will be even fired on initial load. $(document).on 'turbolinks:load', -> $('[data-provider="summernote"]').each -> $(this).summernote lang: 'ko-KR' height: 500 codemirror: lineWrapping: true lineNumbers: true tabSize: 2 theme: 'monokai' callbacks: onImageUpload: (files) -> sendFile files[0], $(this) onMediaDelete: ($target, editor, $editable) -> deleteFile $target[0].src return ``` `Upload` model class is generated as follows: ```sh $ rails g model Upload ``` Using Paperclip generator, `image` attribute is added to `Upload` model class as follows: ```sh $ rails g paperclip Upload image ``` And then, you rake db:migrate for the migration class generated. In `app/models/upload.rb`, `Upload` class will be as follows: ```ruby class Upload < ActiveRecord::Base has_attached_file :image validates_attachment_content_type :image, :content_type => ["image/jpg", "image/jpeg", "image/png", "image/gif"] end ``` `uploads` controller is generated including `create` and `destroy` actions. ```sh $ rails g controller uploads create destroy ``` In `app/controllers/uploads_controller.rb`, `uploads` controller will be as follows: ```ruby class UploadsController < ApplicationController # protect_from_forgery except: :create def create @upload = respond_to do |format| format.json { render :json => { url: @upload.image.url } } end end def destroy upload_id = params[:file_name].split('/')[-3].to_i @uploaded_file = Upload.find(upload_id) @uploaded_file.destroy respond_to do |format| format.json { render :json => { deleted_file: params[:file_name] } } end end private def upload_params params.require(:upload).permit(:image, :image_file_name, :image_content_type, :image_file_size, :image_updated_at) end end ``` In `config/routes.rb`, you should declare routes as follows: ```ruby Rails.application.routes.draw do root "posts#index" resources :posts post 'uploads' => 'uploads#create' delete 'delete_file' => 'uploads#destroy' end ``` > **Note**: Demo screencasts is uploaded on youtube
