I am having problems searching a money-rails/Monetized attribute using ransack. I am only able to search in cents. I have a model (gig) with a money attribute salary. I can create this model no problem with:

 <%= form.input :salary %>

Which saves the value in a salary_cents column as expected as in my gig model I have:

monetize :salary_cents

I can then show the salary in the view with:

<%= @gig.salary %>

The problem I am having is with searching this field with ransack. The salary attribute is null, and the salary_cents attribute is populated as it should be, but this means I can only search in cents.

For the search I am using:

<%= f.search_field :salary_cents_gteq %>
<%= f.search_field :salary_cents_lteq %>

but to search $30, I would have to input 3000. Is there any way of manipulating the inputted data, multiplying by 100, before sending the search request? Are there any easier ways that I am missing?

I have searched this and cannot find any information on searching Money fields with ransack.

Thanks in advance.

Ransack's custom predicates saves the day!

# config/initializers/ransack.rb
Ransack.configure do |config|

    config.add_predicate 'gteq_euros', 
        arel_predicate: 'gteq',
        formatter: proc { |v| v * 100 },
        validator: proc { |v| v.present? }

    config.add_predicate 'lteq_euros', 
        arel_predicate: 'lteq',
        formatter: proc { |v| v * 100 },
        validator: proc { |v| v.present? }
end

once you restart your rails application you could ransack by dollars / euros as you wanted:

<%= f.search_field :salary_cents_gteq_euros %>
<%= f.search_field :salary_cents_lteq_euros %>
