ruby on rails, meta_search and case insensitive oracle

Question

I am using meta_search gem on my rails project. The database is an Oracle database and "like" is case sensitive. Does somebody know how I can create a new condition, or something, for get queries like this:

UPPER(NAME) LIKE UPPER('User Firstname')

Answer 1

meta_search method class - first two code samples. Just instead of :backwards_name rewrite it to be :incasesensitive_name or whatever you want and add such text field to your search form.

UPPER() is built into Oracle AFAIR, so scope may look like this:

scope :incasesensitive_name, lambda {|name| where('UPPER(name) LIKE ?', "%#{name.upcase}%")}

Hope it helps.

Answer 2

Just in case someone needs to do this with ransack:

ransacker :subject_cs, :formatter => proc {|v| v.downcase }, :splat_param => true, :type => :string do
    arel_table[:subject].lower
end
