There is a gem called "Refile". It is great. Go ahead and check this tutorial on how to use it. https://gorails.com/episodes/file-uploads-with-refile here is how to do it.

Add this to your gem file

gem 'refile', '~> 0.4.2', require: ["refile/rails", "refile/image_processing"]

Create a table field using rails migration in your table as image_id of string type.Now comes how to insert into that field and display the image.

Use this in your upload form, largely form_for do |f|

 <%= f.attachment_field :image %>

if you are using rails 4 make sure you pass rails strong parameters.

Put this in your model.rb file where you are storing the image (below class modelname)

attachment :image

displaying the image is simple.

<%= image_tag attachment_url(current_user,:image, :fill, 200, 170, format: "jpg") %>
