After installing the plugin, you should observe the below steps
In model
class Product < ActiveRecord::Base
file_column :image #image is the field name in db for Products table
end
Generate browse button in view
<%= file_column_field “product”, “image” %>
and display uploaded images in your view:
<%= image_tag url_for_file_column(“product”, “image”) %>
However, you may want to protect against the model object having no uploaded image:
<%= image_tag url_for_file_column(“product”, “image”) if @product.image %>
To resize every uploaded image to a maximum size of 640×480, you just have to declare an additional option.
class Product < ActiveRecord::Base
file_column :image, :magick => { :geometry => “640×480>” }
end
You can even automatically create versions in different sizes that have nice filenames…
class Product < ActiveRecord::Base
file_column :image, :magick => {
:versions => { “thumb” => “50×50″, “medium” => “640×480>” }
}
end
and display them in your view:
<%= image_tag url_for_file_column(“image”, “entry”) %>
