This is fairly easy to get wrong - txn_do forces you to have a block

It will start a transaction at the start of the block, and commit it

How do I do it here in Catalyst/DbiX::Class land?
I tried to read up the
http://kobesearch.cpan.org/htdocs/DBIx-Class/DBIx/Class/
Storage.html#txn_do
doc but I can't see how the example can apply to Catalyst.
It says, $schema-txn_do($coderef) to get the schema but in
catalyst,
we access the
database tables directly. For example,
$c-model('myAppDB') gets the schema
I'm a bit confused and have looked in a few places. Can anyone please
educate me?
$c-model('myAppDB')-txn_do( sub {
my $rs = $c-model('myAppDB::Table')-search(..);
# Etc etc
die(Rollback) if $foo; # Exceptions cause rollback
# Etc etc
# If you get here, to the end, transaction is committed for you.
});
Can you please supply a doc patch for one or two of the places you
looked to find this information which will explain it more clearly
for the next person?

Re: [Catalyst] how to implement Transactions (over different db tables) in a Catalyst project
hello there, Tomas,
Thank you :)
Yes, you're quite right there:)
Prior to receiving this reply, I actually wrapped my existing code in
the subroutine within an sub for the txn_do.
sub save_complete_records
{
...
eval
{
$c-model('myAppDB')-schema-txn_do( sub
{
...
$c-forward(
'/subscriptions/_save_address',
[
{ 'policy_id' = $policy_id, }
]
);
...
}
if ($@)
{
$c-log-debug(' Exception manually trapped here : ' . $@ );
$c-model('myAppDB')-schema-txn_rollback or die Cannot ROLL
BACK - Address module;
$c-log-debug(' manually rolled back' );
$c-error(
q{ An error has occured with the listing. If this problem } .
q{persists please contact our helpdesk at
helpd...@insuranceline.}.
q{com.nz.}
);
}
}
To test, I purposedly entered a very long string for one of the database
attributes to make the transaction
fail.
I have the following questions:
1) I looked at the terminal with all the debug messages. I noticed that
the exception was caught and eventhough the roll back was done, I do not
see the print outs from the liens within the if ($@) (exception
handling) section above. Why is that?
2) I noticed that whilst the rollback was successful. the sequence do
not get rolled back.
IS this desired behaviour of DBIx::Class?
To illustrate, before the exception was caught, an entry was made in
my User_Subscriptions database table. The ID was printed out and I took
note of it.
When the operation was complete, I queried my User_Subscriptions
database table (using psql for postgresql for an entry of the noted ID).
No entry of the noted ID was returned.
I went back to the webpage and entered the form with valid attributes
and yes, all
necessary objects were created in the database backend and the sequence
in the User_Subscriptions database table had increased by 1.
Any ideas, Tomas and everyone? :)
thank you :)

Yes, sorry about that - it's a regression / correctness fix. 5.80005
considered anything called 'default' to be a default method, no
matter what attributes you have it - which was a huge pile of fail..
The incorrect behavior was:
sub default : Chained('/') PathPart('foobarbaz') Args(0) = became /
mycontrollernamespace/.*
The correct behavior is:
sub default : Local = asking for mycontrollernamespace/default
sub default : Private = asking to be last-case fallback for
mycontrollernamespace/.*
This is somewhat a regression on 5.7, and somewhat a fix - as we now
correctly handle priorities in all cases with default / Path actions,
allowing the most specific action to match in all cases.

I totally agree. Please nominate where it should be (where did you
look hardest that it wasn't), and we'll put it there instead, with
the clarifications to the expected behavior you're about to make if
it isn't crystal as-is.. :)

Re: [Catalyst] Themes, skins, templates and componentized UI?
- Original Message From: Gunnar Strand gunnarstr...@yahoo.com To: catalyst@lists.scsys.co.uk Sent: Monday, July 6, 2009 3:55:27 PM Subject: [Catalyst] Themes, skins, templates and componentized UI? Hi, I am a little new in the web design area. I'm trying to design an application where the view part must be simple to replace by whomever installs it, with elements of their own design. This would work comparable to themes or skins. I've done some googling, but I haven't got any obvious hits on this. The closest I _think_ is CatalystX::Usul, but I haven't really understood if that's what I'm looking for :-) Also, I would also want the person installing the application to be able to restructure the visual parts using components, where a component could for instance be a result ticker, main menu, member table or such. Perhaps in the way that Joomla does, but the components will be application specific. It's much a matter of deciding what components are present in which views and where. I imagine, for instance, a collection of widgets (button, drop-down-list, text field etc) which are reused in the TT templates. A component would then use these widgets as building blocks, populating them using data from the stash. A view (webpage) would be a template including one or more of these components. A theme could then override any widgets of choice to change the look-and-feel of the whole application instantly. Am I approaching this from the right direction and does anyone know if there exists a framework similar to this to use with Catalyst? Or should I perhaps go barking up the TT tree? ;-) KR, Gunnar --- The closet think to something componentized on the UI side would be Reaction, http://search.cpan.org/~mstrout/Reaction-0.002000/ but that has very high development and I think you'd have to be willing to get your hands dirty with the code.

[Catalyst] Polymorphism?
I'm just wondering if any Catalyst programmers have used polymorphism in the construction of their controller classes. Coming from a Java background I'd like to be a little more OOP about how I implement my controllers. i.e. I'd like to be able have a parent controller with common behavior and override that behavior as necessary in my child classes but still work with the generic parent class. However, I've gotten in the habit of using actions for my application flow. I know it's possible to use chained actions to carry behavior down and I've used that in certain situations but it's not truly polymorphic for generic coding. I'm not sure if I could be utilizing the NEXT library to more advantage.
