activerecord - Rails 4 search bar -

i'm trying create search bar in rails 4 app. i'm user db has 'name' , 'email' columns user's - want users able search other users name or id.

i'm getting this:

activerecord::recordnotfound in userscontroller#index couldn't find users 'id': (all, {:conditions=>["name ?", "%hi@example.com%"]}) (found 0 results, looking 2)

does know i'm doing wrong? i've looked @ railscasts , few forums etc cant past point @ moment.

index.html.erb:

<% form_tag users_path, :method => 'get' %> <p> <%= text_field_tag :search, params[:search] %> <%= submit_tag "search", :name => nil %> </p> <% end %>

model/user.rb:

def self.search(search) if search find(:all, :conditions => ['name ?', "%#{search}%"]) else find(:all) end end

users_controller.rb:

def index @users = user.search(params[:search]) end

routes.rb:

'search' => 'users#index'

are using rails 4? find(:all, ...) old way of doing things. find takes ids now. use:

def self.search(search) if search.present? where('name ?', "%#{search}%") else where(true) end end

also present? test against both nil , blank. maintain in mind can slow depending on database.
