Question

I have recently uploaded my application to heroku and due to the postgresql, the case sensitivity does not work, I am wondering how will I fix this? My code is as followed:

relation = Game.gamsearch(params[:gamsearch])
relation = Game.consearch(params[:consearch]) if params[:consearch].present? 
relation = Game.gensearch(params[:gensearch]) if params[:gensearch].present? 
relation = Game.where("game_name LIKE ?", "#{params[:game_name]}%") if params[:game_name].present? 
relation = Game.where("console = ?", params[:console]) if params[:console].present?

view code:

<%= form_tag games_path, :controller => 'games', :action => 'gamsearch', :method => 'get' do %>
                        <%= text_field_tag :gamsearch, params[:gamsearch] %>
                        <%= submit_tag t('.searchb'), :game_name => nil %>
                        <% end %>

This is the model code:

def self.gensearch(*args)
#search for games by their genre
return [] if args.blank?
cond_text, cond_values = [], []
args.each do |str|
  next if str.blank?
  cond_text << "( %s )" % str.split.map{|w| "genre LIKE ? "}.join(" OR ")
  cond_values.concat(str.split.map{|w| "%#{w}%"})
end
all :conditions =>  [cond_text.join(" AND "), *cond_values]

end

Answer 1

relation = Game.where("game_name ILIKE ?", "#{params[:game_name]}%") if params[:game_name].present? 

notice the ILIKE instead of LIKE
