+Oh wait.
+I'm from the US
+New law

+...banning profanity.
+----
+We need to
+censor
+blogs.
+----
+No problem!
+----
+(Except the political one)
+----
+Back to the code!
+----
+We'll need to
+----
+Validate the text
+----
+(demo of validate)
+----
+# vi lib/Blog/Model/Entry.pm
+
+use Regexp::Common 'profanity_us';
+
+sub validate_body {
+ my $self = shift;
+ my $body = shift;

+ body => 'Would you speak like that in front of your mother? *cough*'
+ )
+ }
+ return $self->validation_ok('body');
+}
+----
+
+Demo of a validation error.
+
+----
+
+Not good enough.
+----
+
+It stops people from blogging.
+
+----
+
+Instead, we can
+clean it up directly
+----
+
+# vi lib/Blog/Model/Entry.pm
+
+
+sub canonicalize_body {
+ my $self = shift;
+ my $body = shift;
+ $body =~ s/$RE{profanity}/**expletives**/gi;

+DatabaseObjects

+Three object types
+----
+Handles

+Database independence
+----
+- Postgres
+- SQLite

+----
+Cachable
+- Single process
+- Memcached

+Collections
+----
+"SELECT main.* FROM ...."
+----
+- Joins
+- Paging

+Does the hard stuff
+----
+Does the boring stuff
+----
+SCHEMA
+----
+No more:
+- CREATE TABLE
+- ALTER TABLE
+- CREATE FOREIGN KEY

+ACTIONS (Controller)
+----
+Actions are just APIs to your app
+----
+(You might call them a facade over your code)
+----
+Actions define method calls
+----
+Actions takes typed arguments and returns results

+Actions are Web Services

+Actions are web services
+----
+Getting started with actions
+----
+Jifty provides three actions for each of your model classes:
+- Create
+- Update
+- Delete
+----
+Just extend (subclass) the defaults
+----
+If we had more time, we'd show you that every action is made of:
+
+- arguments
+- validate_arguments
+- take_action
