Re: [Catalyst] Alternatives to DBIx?
Lyle ha scritto: Kiffin Gish wrote: I'd say that rather than spending time studying SQL::DB, which I found complicated and hard to tackle, you might as well invest the same time and energy anyway in figuring out DBIx::Class. TBH if I really found the need for the DB to match up to objects, then I'd use an Object Database, not a Relational one. The only real argument for using a relational one instead, in that situation, is the performance benefits. When you want top performance from a relational database, you won't be using an ORM anyway. But the question is: do you need raw dbi performance all over the place ? Just as you can write some critical functions in assembly and wrap them up in a C function or C++ class method, you can use an ORM to speed up development and have easier code maintenance, and use dbi+raw sql where you find a performance bottleneck. Also, as someone has mentioned earlier in this thread, DBIC requires a well-designed db schema, so in some way it prevents bad design decisions at the "raw-sql" level, thus helping to acheive good performance right from the start.

The response you are getting, and having a hard time understanding
apparently, is that the worrying about overhead of accessors is
premature optimization that has no benefit to the scope of your real
application.
Unless you provide a NYTProf of your application showing Catalyst is
the bottleneck, nobody is going to care what you are saying.
I'm not sure why you think Catalyst accessors are so slow... on 5.10+
they are faster than Class::Accessor::Fast. Startup time is slower,
but runtime is faster. I'd prefer that.
Oleg, seriously, what are you trying to accomplish here? You aren't
saying anything helpful and you really aren't good at trolling. I'm

relationships between tables in the common and specific databases.
I used myapp_create.pl to create the two models:
perl script/hardware_create.pl model MyhardwareDB DBIC::Schema
Myhardware::Schema::MyhardwareDB create=static dbi:mysql:hardware
'jag' 'passwd' '{ AutoCommit => 1 }'
perl script/hardware_create.pl model CommonDB DBIC::Schema
Myhardware::Schema::CommonDB create=static dbi:mysql:hardware 'jag'
'passwd' '{ AutoCommit => 1 }'
and then put in the relationships between the employee and hardware
tables as under:

Re: [Catalyst] connecting to more than one database

Hi,
The first Catalyst application of mine deals with the leave records of
employees. The second one deals with the hardware that they have been
given. Both these applications require details about the employees like
their name and employee_no. So I put the employee details in one
database called 'common', and the leave particulars in another database
called 'leave' , and the hardware details in a third database called
'hardware'.
I was able to put in the foreign key constraints at the time of table
creation. And these are working. I cannot, for example, insert an
emloyee_no in either the 'leave' or the 'hardware' database if it is not
existing in the 'common' database.
So when I was able to do what I had in mind at the database level, I
thought it would be possible to do the same with Catalyst and
DBIx::Class also. I still haven't lost hope. It would be painful and
inelegant to have to replicate the employee details for each of the web
applications in the respective databases.
I think you are using the word 'database' to refer to both the DBIC
schema and the mysql database, which is confusing.
Since the two dsn in the previous post were the same, I assume your
setup is as follows:
- all the data in a mysql database
- multiple Cat apps, each one with its own DBIC schema, all pointing to
the sama mysql database, but dealing with a subset of tables
If this is the case, then the fact that the fk constraints at the
database level work is to be expected (if you use InnoDB for example).
DBIC, on the other hand, thinks you have multiple databases.

This is the reason you can't make relationships between
different schemas.
If it's not a typo, the two schemas connect to the same database on
the mysql side...
Anyway, I think DBIC sees them as two different databases, even if
their connections strings are the same...

I am working on two Catalyst applications and had earlier set up
separate Mysql databases for each of them. Since some of the
tables
that these two applications use, are the same, I put the common
tables in a third database and created two models in each of the
Catalyst applications. I am, however, unable to set up
relationships between tables in the common and specific databases.
I used myapp_create.pl to create the two models:
perl script/hardware_create.pl model MyhardwareDB DBIC::Schema
Myhardware::Schema::MyhardwareDB create=static dbi:mysql:hardware
'jag' 'passwd' '{ AutoCommit => 1 }'
perl script/hardware_create.pl model CommonDB DBIC::Schema
Myhardware::Schema::CommonDB create=static dbi:mysql:hardware
'jag'
'passwd' '{ AutoCommit => 1 }'
and then put in the relationships between the employee and
hardware
tables as under:
# in Emp.pm
#employee has many hardware
__PACKAGE__->has_many(emp_hm_hw =>
'Myhardware::Schema::MyhardwareDB::Hardware', 'hw_emp_id');
# in Hardware.pm
#hardware belongs to employee
__PACKAGE__->belongs_to(hw_bt_emp_id =>
'Myhardware::Schema::CommonDB::Emp','hw_emp_id');
When I use these accessors in the tt2 templates, i get an
undef error.
undef error -

What am I doing wrong?

there any problem in this, though it may not be the best design. Will
putting the database initialization code in the Model help? I have included
afaict, you should let dbic / cat-model handle the connection to the
database. I usually use something like this: a
MyApp/Model/Main.pm
package which inherits from e.g.
Catalyst::Model::DBIC::Schema
and calls
__PACKAGE__->config(
schema_class => 'MyApp::Schema',
connect_info => [ $dsn, $user, $pass, $options ],
);
This way I don't explicitly connect at startup, but let the framework
perform the actual connection when needed (i.e. at first db access, with
something like $c->model('Main')->resultset('Users')->find($id))

[Catalyst] controller subclass and :Local actions
Hallo,
I have a controller base class that implements the usual crud
actions (list, create, etc.), and I would like to override i.e. the list
method in a subclass, but the subclass' list method doesn't seem to get
called...
In MyApp::Controller::Base:
use base qw( Catalyst::Controller );
sub list : Local {
do stuff
}
In MyApp::Controller::CD:
use base qw( MyApp::Controller::Base );
sub list : Local {
do other stuff
}
when I call /myapp/cd/list the base controller's list action gets called...
Can someone give me a hint ?
Thank you.

Strange. That works fine for me. What does the debug output prints out
for the path dispatch table when the server starts up?
It should look something like this:
[debug] Loaded Path actions:
.-+.
| Path| Private|
+-++
| /base/list | /base/list |
| /cd/list| /cd/list |
'-+'

It works fine for me too, today :-)
I always use the dev server with -r, so it could be that the thing was
not picked up until I CTRL-C'ed the server and restarted manually...
Sorry for the noise.

But is that efficient? It looks like you are getting MySQL to return the
entire data set and then making Perl filter it. That can't be efficient.
Here it is a short code example that might appear in a controller:
sub author : Local {
my ($self, $c) = @_;
#Variables you might get after the user submits a form:
my $name = $c->req->params->{name};
my $country = $c->req->params->{country};
#Search the database for all fiction authors:
my $authors = $c->model("DB::Authors")->search({
style => 'fiction',
});
#Until this point DBIC doesn't touch the database.
#Add filters based on what the user searched using the form:
$authors = $authors->search({name => {-like => "%$name%"}) if $name;
$authors = $authors->search({country => $country}) if $country;
#Until this point, DBIC also didn't touch the database.
#Add the $authors object to the stash, to be able to print it in a
template:
$c->stash->{authors} = $authors;
#Until here, DBIC didn't touch the database
}
#And the subroutine ended.
And then you can print some things using a Template-Toolkit template
(authors.tt):
[% IF some_variable = 1 %]
[% FOREACH author = authors.next %]
Name: [% author.name %]
Country: [% author.country %]
Localized birthday month: [%
author.birthday.set_locale('fr').month_name %]
The books of this author:
[% FOREACH book = author.books %]
[% book.title %] - [% book.editor %]
[% END %]
[% END %]
[% END %]
And at this point, DBIC still doesn't touch the database if the variable
"some_variable" is not equal to 1 so the code below the IF line
shouldn't be executed.
But if the variable is 1, only at this point DBIC executes the necessary
queries and get the data. And you have seen that due to the relations
that were created in the DBIC result classes, it would be very simple to
access not only data about the authors, but about his books or data that
can be found in other related tables, without needing to define a new
query.
I wrote this code in Outlook Express and it might have bugs because I
didn't test it, but I hope it helps to make an idea about what DBIC can do.

I think this example is very interesting and should end up into the wiki
somewhere!
I think it can be a good selling point for DBIC, but I've not seen it
explained so well until now (but I admit I've not looked up the docs in
a while...)
Thank you.
