How to turn on REGEXP in SQLite3 and Rails 3.1?

Question

I have the following statement in Rails 3 using an SQLite3 database:

word = \'Hello\'
word_entry = Word.where(\"name REGEXP :word\", {:word => \"[[:<:]         


        

Answer 1

From source of sqlite3_ar_regexp project, I extract this:

    db = ActiveRecord::Base.connection.raw_connection
    db.create_function('regexp', 2) do |func, pattern, expression|
      func.result = expression.to_s.match(
          Regexp.new(pattern.to_s, Regexp::IGNORECASE)) ? 1 : 0
    end

Improved upon a previous answer with ActiveRecord::Base.connection.raw_connection so that db name isn't needed
