Question

class SearchController < ApplicationController
  def autocomplete
    @location=Location.find_by_sql("select * from locations where name like ?;",['%'+params[:term]+'%'])
    render  json: @location
  end
end

I think query like this is not working as expected:
select * from locations where name like ‘%XXXX%’;

Neither can I wrote code like this:
@location=Location.find_by_sql(“select * from locations where name like ‘?’;”,
the function will fail to recognize the params

So how could I implement such keywords filtering queries?

Answer 1

This should work:

@location = Location.where("name LIKE ?", "%#{params[:term]}%")
