Rails 4: Merit Gem: DRYing up the PointRules code? -

is there way dry pointrules class bit? tried didn't work:

%w(attr1 attr2 attr3).each |attribute|   score 10, on: 'comments#create', |comment|     comment.attribute.present?   end end 

it gave me error:

private method `attribute' called for... 

final edit:

the answer provided below works plus can dry code further doing this:

%w(attr1? attr2? attr3?).each |attr|   score 5, on: ['comments#update', 'users#update'] |item|     item(attr).call   end   score 10, on: ['comments#create', 'users#create'] |item|     item(attr).call   end   score 15, on: ['comments#delete', 'users#delete'] |item|     item(attr).call   end end 

sorry wait :(

here solution might you

%w(attr1? attr2? attr3?).each |attr|   score 10, on: 'comments#create', |comment|     comment.method(attr).call   end end 

active record adds boolean methods columns, why used question mark on columns.

please let me know if have questions.
