Simple Blog Application

(Chris Kuffo) #1

I created a simple blog application and wanted to enforce a rule that every post must have a title. In my post.rb file I have this code

class Post < ActiveRecord::Base

attr_accessible :body, :title

validates_presence_of :body, :title

When I update my post and delete my title I do not receive an error.

Start rails console and type:


What is the output?

What is the exact problem? You just do not receive any error, or post is saved without title?

If you need to show errors then you need to add something like this to your view:

<% if @post.errors.any? %>
  <div class="alert alert-error alert-block">
    Some errors occured:
      <% @post.errors.full_messages.each do |error| %>
        <li><%= error %></li>
      <% end %>
<% end %>

The output was false… I was able to resolve my problem though…seems liked I placed


in the wrong file. now i receive an error advising me that every post needs something in the body and title.
