[Rails] undefined method

Ruby on Rails Thursday, April 2, 2015

hi,

I am trying to make use of a method located in my model (see below) directly at my view but I am getting undefined method. how can solve this ?

app/model/operation.rb

def all_products_have_same_posters_count?

products.all? { |p| p.posters.count == products.first.posters.count }

end

_show.html.haml

-if @operations.all_products_have_same_posters_count?

="foobar"

any recommendations ?

thanks.
