hi

here is my form fields

      <tr>
            <td><%= text_field  :title, :name =>

‘external_link[title][]’ %>

<%= text_field :url, :name => ‘external_link[url]
[]’ %>


<%= link_to_function ‘Add’, “add();” %>

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

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