hello,
I have a model (item) with one attachment (photo) and one style (small):
class Producto < ActiveRecord::Base has_attached_file :photo, :styles => { :small => "50x50"}, end
I would like to add a new style (:large), so I modify item.rb:
class Producto < ActiveRecord::Base has_attached_file :photo, :styles => {{ :small => "50x50"},{ :large => "150x150"}} end
it seems to be ok, but when I submit in edit or new views, I get the following error:
NoMethodError (undefined method `' for nil:NilClass): app/controllers/admin/items_controller.rb:64:in `update' app/controllers/admin/items_controller.rb:63:in `update'
Controller code: def update @item = Item.find(params[:id]) respond_to do |format| if @item.update_attributes(params[:item]) format.html { redirect_to(admin_items_path, :notice => 'OK') } else format.html { render :action => "edit" } end end end
If I remove the new style (:large) in item.rb everything works fine again...
Could someone help me?
Thanks
