From: PerfectDayToChaseTornados Date: 2007-03-30T05:40:07+09:00 Subject: why is error not showing on rhtml page Hi All, Would someone please be kind enough to help? I think I've got everything right (though obviously I havent). I am putting some validation in my model class & expecting the error to show on the page, however it isnt. When I submit the page with a title value, my 'created chapter' message appears & the chapter is persisted. If I submit without the title, validation fails (as it should), the 'something went wrong dude' message is shown. But the 'error_message_on(:chapter, :title)' is not shown on the page. I've tried several things, but to no avail & I'm now tearing my (already thinning) hair out! Code follows. chapter.rb has validates_presence_of :title chapter_controller.rb class ChapterController < ApplicationController def add_chapter if request.post? chapter = Chapter.new(params[:chapter]) previous_chapter = Chapter.find(params[:previous_chapter_id]) if params[:previous_chapter_id] chapter.parent = previous_chapter if previous_chapter chapter.is_actual = false if chapter.save flash[:notice] = "created chapter #{chapter.title}" redirect_to :action => 'add_chapter' else flash.now[:notice] = "something went wrong dude!" end end flash[:parent_id] = params[:parent_id] if params[:parent_id] end end add_chapter.rhtml <%= stylesheet_link_tag 'booksite', :media => "all" %> <% if flash[:notice] -%>

<%= flash[:notice] %>

<% end -%> <% form_for :chapter, :url => { :action => :add_chapter } do | form |%>

<%= form.text_field :title, :size => 40 %><%= error_message_on(:chapter, :title) %>

<%= form.text_area :synopsis, :rows => 20, :cols => 60 %>

<%= form.text_area :content, :rows => 30, :cols => 60 %>

<% if flash[:parent_id] -%> <%= hidden_field_tag :previous_chapter_id, flash[:parent_id], :size => 40 %> <% end -%> <%= submit_tag "Submit Chapter", :class => "submit" %> <% end %> Many thanks :-) -- pdtct
