active record validations by Eshwar

hi

here is my form fields

          <tr>
                <td><%= text_field :title, :name =>
'external_link[title][]' %></td>
                <td><%= text_field :url, :name => 'external_link[url]
[]' %></td>
      </tr>
      <tr>
                <td><%= link_to_function 'Add', "add();" %></td>

if i click add link there will be added 2 more text fields as above

in the controller iam using like

def create
    puts params[:external_link][:title].inspect
      params[:external_link][:title].each_with_index do |l, i|
  ExternalLink.create!({:title => l, :url => params[:external_link]
[:url][i], :label => params[:label]})
      end
      redirect url(:external_links)
  end

in the model i have specified as

validates_presence_of :title, :url

the problem is when i submit the the form with out entering any
details its not checking validation
its giving error like

Validation failed: Title can't be blank, Url can't be blank

how can i do that in the controller and model

If you use the ! variants of save, create, update_attributes etc...
then validation failures raise an error instead of returning false.
