How to declear association from an array in Rails 4 model? -

we following in user model:

class user < activerecord::base   model_names = ['pets', 'computers' ]   model_names.each |a|     has_many #{a.to_sym}   end  end

is code above going work in rails 4? or better way that. thanks.

yes can that, rails expects names lowercase, snake-case symbols instead of class names.

you can try tableize that

if need them classnames, you'll need like:

 model_names.each |a|    has_many a.tableize.to_sym  end

though tbh i'd go other way eg:

class user < activerecord::base   model_names = [:pets, :computers ]   model_names.each |a|     has_many   end  end

then if ever needed use model_names elsewhere use: model_names.map{|a| a.classify } possibly constantize turn real class.
