Upload Image

This Rails gem simplifies the implementation of uploading image. With it, you can write the following line in your *.html.erb as a view component:

<%= upload_image form: f, image_name: :avatar, width: 150, height: 150 %>

Then you will get:

It takes advantages of carrierwave and cropper.js.

Usage

There are some places you need to modify in your Rails app. For example:

• JavaScript asset file app/assets/javascripts/application.js js //= require upload-image
• Stylesheet asset file app/assets/stylesheets/application.scss

//= require upload-image

• Model file ruby class User < ApplicationRecord mount_uploader :avatar, ImageUploader include Croppable end
• CarrierWave uploader file ruby class ImageUploader < CarrierWave::Uploader::Base include Croppable ... end
• Controller file ruby class UsersController < ApplicationController include Croppable ... end
• View file ruby <%= upload_image form: f, image_name: :avatar, width: 150, height: 150 %>

Then you are good to go.

Installation

Add this line to your application's Gemfile:

gem 'upload-image', '~> 0.1'
