>From the comments on the file, one of the main short hand usage of 'presence' method is :
# For example, something like # # state = params[:state] if params[:state].present? # country = params[:country] if params[:country].present? # region = state || country || 'US' # # becomes # # region = params[:state].presence || params[:country].presence || 'US' However the '||' use case does not play well if the Object is a boolean type. Example usecase : # checked = false # checked.presence || true #=> this returns true even even though checked has a value. Would it be a good idea to have a default value on presence method the way we can provide one with 'fetch' method ? . Example : def presence(default_value = nil) return self if present? default_value end checked = false checked.presence(true) #instead of 'checked.presence || value' # This also reducers from using '||' and we can just use the argument. Very similar to hash.fetch(key, default_value) Not a big case/change, but was wondering if someone was having the urge of adding this one line to make life a little easier :) -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
