Question

I am strugging to find a command that enables me to identify those records in an array which contain a specific word, and wondered if someone could point me in the correct direction.

Essentially I have names in one column and addresses in another. I would now like to restrict the data to just those people in a certain city, so for example i want to show all those who live in London – i.e. ‘London’ must be contained within their address string.

Is it possible to use the WHERE and LIKE functions to do this somehow?

Answer 1

Do something like this:

def SomeModel < ActiveRecord::Base
  scope :contains_city,
    lambda { |city| where("some_models.address LIKE ?","%"+city+"%" ) }
end

#Usage:
records = some_instance_of_model.contains_city "London"
