Question

well i have this problem

i have this in my model service

class Service < ApplicationRecord
  belongs_to :user

    has_attached_file :images, :styles => {:md => "300x300>", :large => "500x500>" , :xl => "700x700#"}, :default_url => "/app/assets/images/thumb/missing.png"
    validates_attachment_content_type :images, :content_type => /\Aimage\/.*\Z/   

end

and this in my view Services#index

    <div>
      <%= image_tag service.images(:md)%>
    </div>

but there's a problem in my view the image set when i put :large or :xl but when i put :md the images don't shows. i don't know what's happening

Answer 1

If :large and :xl are working when you replace it with :md in your index view, then I would guess that there's simply no version for :md available to show. Have you added :md to the model, after you actually already uploaded an image? I would delete the image and try that again.
