Hi,

I have view page which takes all the information like contact's emails , phones no's etc and saves different tables. I want to save more than one email id's for a particular contact.

view page is something like this..

. . Email 1 : <%= select 'email', 'email_type', %w(Business Personal), :include_blank => false %> <%= text_field 'email','email',:size=>"35",:maxlength=>"80" %> <%= radio_button 'email', 'isprimary', '1' %>Primary Email 2 : <%= select 'email', 'email_type', %w(Business Personal), :include_blank => false %> <%= text_field 'email','email',:size=>"35",:maxlength=>"80" %> <%= radio_button 'email', 'isprimary', '1' %>Primary . .

Controller is :

def create       @contact = Contact.new(params[:contact])       @contact.emails << Email.new(params[:email])       @contact.phones << Phone.new(params[:phone])       @contact.addresses << Address.new(params[:address])       puts "hellooooooo bharati"       params.inspect       if @contact.save          flash[:notice] = "Contact was successfully created."          redirect_to :action => 'list'       else          render :action => 'new'                   flash[:notice] = "Contact was not created."       end    end

Can any one help me how to send more than one email ids to controller..

There's two separate problems here: - how you manage the ui, ie adding extra textfields to the page - how you convince rails to treat these textfields as an array.

The key to the second part is how you name the parameters. In particular parameters ending with a are treated as arrays.

Yes . I was able to submit more than one text field values.. but now my issue is how do i differentiate radio buttons with the same name.. both the radio buttons are getting selected :(.. here is the code

<% form_for :@contact do |f| %>              <% @contact.emails.each_with_index do |email, index| %>              <% fields_for "email[#{index}]", email do |f| %><tr> <td>              Email &nbsp &nbsp;              <%= f.select :email_type, %w(Business Personal), :include_blank => false %>              <%= f.text_field :email %>        <%= f.radio_button :isprimary ,'index' %>Primary              </td></tr>               <% end %>           <% end %> <% end %>

the builders yielded by form_for and fields_for have the same name, so they'll be overwriting each other (which isn't what I thing you want). Also shouldn't the second parameter to radio_button be index and not 'index' ?

ya. got it. But there exists an issues.. When i select radio button
i ll get the following error. . "undefined method `values' for "1":String" where as the other values get saved if i do not select radio button.

From the code I'd guess that you end up with params[:email]
containing the string 1, which you then try and call values on.
