Uploading files to the cloud isn't the easiest. In the past I've used AWS S3 (which is really good) but configuring my API keys to have the correct access & setting up mirrors into another provider is tricky.
I quite like that Simple File Upload allowed me to get setup within a few minutes & also the founder has a fantastic podcast.
The Code
The full source code can be found on GitHub.
First I updated the layout to include the JavaScript snippet.
<!-- app/views/layouts/application.html.erb -->
<script src="https://app.simplefileupload.com/buckets/23021e637aaa8acce48a1862573a6c23.js"></script>
Then I wrote a migration to add the field image_url to my posts model.
# db/migrate/20210125143751_add_image_url_to_posts.rb
class AddImageUrlToPosts < ActiveRecord::Migration[6.1]
def change
add_column :posts, :image_url, :string
end
end
Then I updated the posts form to include the image_url field. For the upload field I added the simple-file-upload class.
<!-- app/views/posts/_form.html.erb -->
<div class="field">
<%= form.label :image_url %><br />
<%= form.text_field :image_url, class: 'simple-file-upload' %>
</div>
# app/controllers/posts_controller.rb
class PostsController < ApplicationController
# [..]
private
# Only allow a list of trusted parameters through.
def post_params
# I added image_url to the permitted params
params.require(:post).permit(:title, :body, :image_url)
end
end
