Hi all
I wrote a small form and I am trying to check if the fields are
populated.
My Model is:
class Contact < ActiveRecord::Base
validates_presence_of :name, :email, :body
validates_length_of :body, :maximum =>2000
end
-----Controller
class ContactController < ApplicationController
def new
@contact = Contact.new
end
def create
@contact = Contact.new(params[:contact])
@contact.save
end
end
------Viewers
New view
<%= error_messages_for :contact %>
<% form_for @contact, :url => { :action => ''create''
}, :html => {
:method => :post } do |f| %>
<fieldset>
<legend>Please send your message: </legend>
<p><label>Your Name:<br /><%= f.text_field :name, :size
=> 25
%></label></p>
<p><label>Your email:<br /> <%= f.text_field :email, :size
=> 25
%></label></p>
<p><label>Message:<br /><%= f.text_area :body, :rows =>
10, :cols => 30
%></label></p>
<p><label><%= submit_tag ''Submit'' %>
</label></p>
</fieldset>
<% end %>
Create view
<h2>Thank you for your interest in my site</h2>
When the entry fields are not populated the forms shows the create view
and does not show any error message. why?
thanks

You want something more like this: def create @contact = Contact.new(params[:contact]) unless @contact.save render :action => ''new'' return end end Or this which is pretty close to the default generated by Rails scaffolding. def create @contact = Contact.new(params[:contact]) if @contact.save flash[:notice] = ''Contact was successfully created.'' redirect_to(contact_path(@contact)) else render :action => "new" end end --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
