NameError at / uninitialized constant ActionView::CompiledTemplates::Truncato

[grimmwerks]

Can this be used in a view? Seems be getting strange when I'm trying to render some html.

[jorgemanrubia]

Have you included the following in your Gemfile?

gem 'truncato'

And executed bundle install after that?

It should work just fine.

[grimmwerks]

Well, did do all of that. Don't know if I'm calling it wrong, have tried a number of ways: :slide_text => (Truncato.truncate episode.description, max_length: 10),

gets me uninitialized constant ActionView::CompiledTemplates::Truncato -- this is rails 4.
