Question

I was wondering if it’s possible to pass in a parameter to methods when you’re using the :if option with the ‘with_options’ method.

For example, can I call something like this?

 
 with_options :if => :is_user_this_level?(threshold_level) do |some_object|
    some_object.validates_with ObjectValidator
 end

I’m wondering if it’s possible to pass in the variable ‘threshold_level’ to the :if option method. Basically I want to do this because I don’t want to have methods like :is_user_level_two?, :is_user_level_three? and so on and so forth.

Also if there’s a RAILS way of doing this and I’m barking up the wrong tree please let me know.

Thanks!

Answer 1

The usual :if option for ActiveRecord callbacks can take a lambda as its argument so maybe this will work:

with_options :if => ->(o) { o.is_user_this_level? threshold_level } do |some_object|
    some_object.validates_with ObjectValidator
end
