Rails - Jun 2014 - How can I check this ?

Hello, 

Suppose I have this model : 

class Member < ActiveRecord::Base
end

Now I have this controller : 

class MemberController < ApplicationController
  def new
     @member = member 
  end
end

and this form : 

<h1>Add a new member</h1>
<%= form_for @member do |form| %>
 
  <p>
    <%= form.label :name, "Name: " %>
    <%= form.text_field :name %>
  </p>
 
  <p class='buttons'>
    <%= form.submit "Shorten my URL" %>
  </p>
 
<% end %>


Now I have filled in the form the name "roelof"

How can I later check if there is a member with the name "roelof"
or can I do @member.name = "roelof" 

Roelof
