Here is a method on how to upload file without using any gem and only by using rails,

Solution :=>

    def create
        @photo = Photo.new(photo_params)
        uploaded_io = params[:photo][:photo]
        File.open(Rails.root.join('public', 'uploads', uploaded_io.original_filename), 'wb') do |file|
           file.write(uploaded_io.read)
         end
        if @photo.save
          flash[:success] = "The photo was added!"
          redirect_to root_path
        else
          render 'new'
        end
      end


def upload
  uploaded_io = params[:person][:picture]
 File.open(Rails.root.join('public', 'uploads', uploaded_io.original_filename), 'wb') do |file|
    file.write(uploaded_io.read)
  end
end

And your form.html.erb in views should contain this, it is very simple,

 <%= form_for @photo do |f| %>
      <%= f.file_field :photo %>
      

        <%= f.submit "Upload" %>
      
    <% end %>

and finally the model should have ,

  has_attached_file :image
