I am trying to do the calculation of a multiplication inside a div, the calculation comes from the values that enter in 3 inputs that are inside a Rails form, I want to do this using Stimulus Reflex but I have not succeeded, some clue?
Thanks a lot.
Posted in Pagy Frontend Extra MAterialize
I followed your toturial of pagination with Pagy gem, all is fine until when I add the extra frontend materialize. I did this:
- Create a pagy.rb file into config/initializers folder
- Add this line require 'pagy/extras/materialize' in pagy.rb
- In my view use <%= pagy_materialize_nav(@pagy).html_safe %>
when I restart rails server, get this error:
`require': cannot load such file -- pagy/extras/materialize (LoadError)
What can I do to solve it?
I trying to upload files with Carrierwave in my Rails app, files could be jpg, png, pdf or docx. Files jpg and png upload fine but pdf or docx don't, i get the error "...Minimagick, maybe it is not an image?", i read many forums and they say the error could be about the Carrierwave versions.
I need to validate in the uploader that create version only when the file is an image jpg or png.
