while developing a rails you might want to allow your users to upload an image provides an easy and free way of achieving that.... sounds good? let's get started. Application Cloudinary Oh, wait before we start you'll need an API key from if you don't have an account yet, . Alright let's get started now. Cloudinary go ahead and create it Assuming that you have a rails Application with a Post model We'll start by adding cloudinary and carrier wave to Our gem file in the following order. gem 'carrierwave' gem 'cloudinary' then run Next, if you don't have one yet generate an uploader by running bundle i rails g uploader image also, you'll need to have an image column in your post table assuming that you have a post model you can run rails generate migration AddImageToPosts image: string After running let's create a file in the folder, let's go ahead and add our configurations rails db:migrate cloudinary.yml config #config/cloudinary.yml development: cloud_name: CLOUD NAME api_key: 'API KEY' api_secret: API SECRET enhance_image_tag: true static_file_support: false production: cloud_name: CLOUD NAME api_key: 'API KEY' api_secret: API SECRET enhance_image_tag: true static_file_support: true after adding the configurations we need to mount our uploader in the post model # app/models/post.rb class Post < ApplicationRecord mount_uploader :image , ImageUploader end next, we need to configure our uploader to work with Cloudinary. your should look like this app/uploaders/image_uploader.rb #app/uploaders/image_uploader.rb class ImageUploader < CarrierWave::Uploader:: Base include Cloudinary::CarrierWave process convert: 'png' process tags: [ 'post_picture' ] version :standard do process resize_to_fill: [ 100 , 150 , :north ] end version :thumbnail do resize_to_fit( 50 , 50 ) end CarrierWave.configure do |config| config.cache_storage = :file end end And now we are ready to start uploading images to our . app in our form for a post creating < fieldset > <%= f.label :image , 'image' %> <%= f.hidden_field :image_cache %> <%= f.file_field :image %> </ fieldset > to display the image for a given post < img src = "<%= @post .image %>" /> By now we should be able to upload and display from our application. images learn more at https://cloudinary.com/documentation/rails_carrierwave I hope this post was helpful if you have a question or a suggestion leave a comment or find me on twitter
