[Catalyst] Working a Solr Model -- Follow Up

2013-10-06 Thread John Karr
After trying to work with Apache::Solr and running into a brick wall 
there, I went back to WebService::Solr and reread the documentation and 
looked at the source code and decided to give it another try and start 
over.


This time it worked, and I was able to return a 
WebServer::Solr::Response object and pass it to the view. Comparing my 
failed experiment with the working one I figured out what caused the 
Unicode errors. I was even able to propose a patch to implement a minor 
feature request that was sitting in the rt.cpan queue.


Summary of the 3 modules I looked at for implementing a Solr Model.

Rejected: Apache::Solr
Returned a resultset that didn't work in Template::Toolkit, had write 
ugly code to convert to array of hashrefs.
I could not figure out how to use a filter query (they are absolutely 
required for how I intend to use Solr).


Rejected: SolrBeam
Must download from GitHub instead of CPAN.
Despite the oddness of feeling like I was reading Ruby I was able to do 
some debugging in the module, but still didn't get it to work.


Selected: WebService::Solr
You must read all of the submodule documentation, everything I needed to 
figure out was somewhere in the documentation, but often not in the main 
module's documentation.
Has its' own Model Adaptor, but it also works if you just extend 
Catalyst::Model.
The code itself was comprehensible and I was able to logically trace a 
request through it, and also to submit a very minor feature patch.

Implements the features I've tried to use so far.

I plan to write a how-to, which I'll post on my blog, if there is going 
to be an Advent Calendar this year, let me know who is collecting 
submissions for it and I'll submit the article in POD.

Re: [Catalyst] Working a Solr Model -- Follow Up

2013-10-06 Thread John Karr
More important than the ugly code to get output to display is that I 
couldn't figure out how to use a necessary solr feature. Equivalent to a 
DBD for a SQL database that doesn't support subqueries in a select.


Unfortunately, not all of my unicode woes have not been resolved, I have 
a description field that is causing IO::Handle to throw a wide character 
error on template rendering, and a bug reported for WebService::Solr 
since there does after all appear to be a real unicode issue.


As a workaround I wrote a macro in Template::Toolkit.

[% MACRO utfclean(field) PERL %]
  use utf8;
  my $field = $stash-get('field');
  utf8::encode($field);
  print $field ;
[% END %]

Probably could have sorted this by passing the Solr resultset to a 
subref set to $c-stash.  so you end up with something like [% SET 
data =  handle_stupid_resultset(data); WHILE (x = data.iterate); 'do 
stuff with ' _ x ; END;  %] in your template. It's the poor man's 
approach to putting new object models in the template rendering engine.

Re: [Catalyst] Working a Solr Model

2013-09-30 Thread John Karr
Thanks for the suggestion, but I just spent some time looking at 
SolarBeam, and found that the example code did not work.


A little time debugging it confirmed that it internally constructed a 
valid query url  string which when pasted into a browser resulted in 
multiple found documents, but SolarBeam was getting 0 documents found. 
Since the last release was a year ago, it is quite possible that 
something changed to break it (I'm using SOLR 4.4, was the author 
working with the 3.x series?). I also noticed that you (Marcus R) 
started a fork.


Since I've been able to work-around the issues with Apache::Solr I'm 
starting my project with it.



We have been using SolarBeam - https://github.com/judofyr/solarbeam

It uses Mojo::UserAgent, and will allow parallel requests, even if you 
use catalyst. We found this very useful when writing search intensive 
apps.

RE: [Catalyst] Resources to learn catalyst

2012-03-04 Thread John Karr
The best resource out there is the Tutorial. 

I would recommend that you spend some time on Moose and Template Toolkit
before getting serious with the Tutorial, and also you definitely need to
understand the material in the O’Reilly Intermediate Perl book. The biggest
drawback to the Tutorial is that it is more about DBIx::Class than Catalyst,
the only DBI Models for beginners documentation I know of is what I put on
my own technical blog
(http://brainbuz.org/techinfo/Catalyst-Model-Simple-Tutorial.html). If
you're learning programming you should learn DBI/SQL before coming to terms
with any ORM.

RE: [Catalyst] How best not to use the system perl

2011-09-30 Thread John Karr
I recently put up an article on my technical blog (brainbuz.org/techinfo).

Here's the cut and paste:

 Installing an Alternate Perl with perlbrew 

  put a current Perl at /usr/bin/perl5. I prefer this solution to the env 
perl approach many others have chosen. It does require that for your scripts 
you change the #! line by appending the 5, but it is much easier to append a 5 
to the line than remember where your alternate perl is buried in the file 
system (for scripts run outside your environment).

To begin, you’ll need to fire up your system CPAN for its first and only ever 
run. But even before that you may need to install a few things like gcc. On 
ubuntu it is as simple as (sudo) apt-get install build-essential. You also need 
to decide which user is going to maintain perlbrew, it is not unreasonable to 
choose root, it is also quite reasonable to choose a different user.
(sudo) cpan App:perlbrew

Say yes to installing dependincies 89 times. There are two tricks you can use 
to make this a little easier: install App::cpanminus first, it has fewer 
dependencies and can install perlbrew quietly, alternately Ubuntu Oneric has a 
perlbrew package, install it and then use perlbrew’s self update option.

If installation of perlbew fails, open up a cpan session and type

force notest install App::perlbrew.

From this point onwards we consider ourselfs to have 2 perls, our real Perl 
(perl5) the system perl which we will never touch, but which is a dependency 
for packages needing perl we might have installed.
 export PERLBREW_ROOT=/opt/perlbrew
(/usr/perlbrew and /usr/local/perlbrew are also good choices)
 perlbrew init 

/opt/perlbrew/bin/perlbrew available
/opt/perlbrew/bin/perlbrew install 

Using Perl 5.14.1 as an example, type the following two lines
ln /opt/perlbrew/perls/perl-5.14.1/bin/perl /usr/bin/perl5
ln /opt/perlbrew/perls/perl-5.14.1/bin/perl5.14.1 /usr/bin/perl5.14.1

This will make Perl5.14.1 your default perl5, and it will give you a specific 
alias to perl5.14.1 if in the future you need to invoke it specifically you can 
type perl5.14.1 from anywhere without having to remember the full path.

Install cpanminus

Now that you have your new perl installed, even though perlbrew has an option 
to do this I recommend using the cpan in your new perlbrew directory. ./cpan 
App::cpanminus, configure cpan and answer the prompts.

When this is done go to /usr/bin, if you don’t have links there for cpan and 
cpanm copy them from your new perl’s directory, if you do, they’re just 
wrappers, edit the #! line to /usr/bin/perl5, so that if in the future you have 
a newer perl5, you won’t need to touch them.

Special case: Padre.

Padre requires a multi-threaded Perl, Perlbrew does not build a multi-threaded 
Perl by default. I update Padre about once a month. You have a two choices, you 
can tell Perlbrew to build a threaded Perl, or you can leave Padre on your 
system Perl, which means that you need to make sure that you update it in your 
system Perl, not your real Perl. If you don’t want a threaded perl a third 
option would be to build a special threaded perl for Padre (but as long as it 
works with system perl, why bother?).
/opt/perlbrew/bin/perlbrew install \
perl-5.xx.x -Dusethreads -Duselargefiles \
-Dcccdlflags=-fPIC -Doptimize=-O2 \
-Duseshrplib -Dcf_by=Your_name_here \
-Dcf_email=Your_email@here

Hi,

I have got a new server that I want to put into production. To comply with the 
manufacturer, I have installed RedHat 6.1 on it. Up till now we have used 
Debian based machines and have been using the system perl. That worked ok 
because all the necessay libperl*.deb could be installed via the package 
manager. That's not an option with yum. I know using the system perl is frowned 
upon by some so I'd like to do the right thing before the server is deployed. 
AFAIK, there are two options; 1) install a perl from source into somewhere like 
/usr/local and set-up the environment so that's the perl that's used or 2) use 
the system perl (5.10.1) and local::lib. I'm sure there are others with my 
hardware set-up and I'd be interested in hearing what approached they've taken. 
Similarly if there are other options to consider or there are strong reasons 
for using one approach over an other, I'd appreciate hearing them.

Thanks,
Dermot.

RE: [Catalyst] fastcgi script returns 404

I recommend Starman over fastcgi. I never had an easy time with fastcgi, and 
when I finally gave starman a shot it was surprisingly painless, it was pretty 
easy to make an upstart job out of, and I can ditch mod_perl. I have no

Subject: [Catalyst] fastcgi script returns 404

Hello all,

I have a catalyst installation that I'm bringing up from scratch in a new 
environment.  I've decided to go with lighttpd / fastcgi as the web server.  
When running the server script (the project is named map, so it's the 
map_server.plhttp://map_server.pl script), pages seem to come up just fine.  
However, when I start lighttpd, and run the 
map_fastcgi.plhttp://map_fastcgi.pl script with the following command line:

./script/map_fastcgi.plhttp://map_fastcgi.pl --listen 
127.0.0.1:9000http://127.0.0.1:9000 --nproc 5 --keeperr 2

It seems that only the index page of the site is served properly - any other 
link that I click on just results in a 404.  So it seems that I am doing 
something wrong with fastcgi.  Can anyone recommend what I need to do 
differently?

For informational purposes - I run lighttpd with the following configuration 
file:

server.document-root = /home/mapper/artplot/root/
server.modules += ( mod_fastcgi )
server.port = 80

server.username = mapper
server.groupname = mapper

mimetype.assign = (
  .htm = text/html,
  .html = text/html,
  .txt = text/plain,
  .jpg = image/jpeg,
  .png = image/png
)

static-file.exclude-extensions = ( .pm, .pl, .conf )

fastcgi.server = ( =
((
host = 127.0.0.1,
port = 9000,
))
)

RE: [Catalyst] Simple tutorials

2011-09-13 Thread John Karr
I strongly recommend the Catalyst Tutorial. It is denser than I would have 
liked when figuring Catalyst out, and sometimes digresses about outdated 
versions of Catalyst, other than that my biggest gripe is that it completely 
ignores DBI Models, which means that if you don't know DBIx::Class coming in, 
prefer another ORM, or prefer SQL to ORM you have to put a lot of effort into 
DBIx::Class which is very distracting from understanding the rest of Catalyst. 
I also recommend becoming familiar with TemplateToolkit and Moose before 
starting work on Catalyst, just so that you have less to grasp while working 
through the Catalyst/DBIx::Class Tuturial.

I've written an auxilliary document on using DBI models (the version up is 
about half complete. A new version should be going up by the end of the month), 
you can find it at

runs error free when run in its entirety. But I can't get Model Tests to run. 
My Model is DBI based, where each DSN has a MyApp::Model::DSN parent module and 
then there are MyApp::Model::DSN::Table child modules which contain the methods 
relevant to each table. I would like to access my model methods in a manner 
similar to how I do in an application:

Hi John

I think I would just add something like this to the model:

has db = (
is ='ro',
isa = 'DBIx::Simple',
lazy_build= 1,
handles = [qw/query select insert delete/], # Etc.
);

sub _build_db {
my $self = shift;
return DBIx::Simple-connect($self-dbh);
}

then you should be able to use $self-db, $self-query etc in your subs.

RE: [Catalyst] DBI Models Question.

2011-06-11 Thread John Karr
The mistake in my  code brings up the other  question (which applies to ORM 
models as well): How to get the model to take its parameters from 
appname.conf instead of having to input them directly in the model.

Fortunately that was just a test server and no big deal to change its 
passwords, but nearly every time I copy a catalyst application from one server 
to another server I need to edit the model. And the problem is obvious (and as 
shown by my post easy to mess up) if you are sharing some model code via irc or 
a mailing list.

RE: [Catalyst] Has anyone read the book Catalyst 5.8 : The Perl MVC Framework yet?

2010-10-24 Thread John Karr
It came out just as I was trying to learn catalyst. From a beginner
perspective it wasn't of any value -- thankfully Kennedy Clark has been
doing an excellent job with the Tutorial on CPAN, because that's how I
figured most things out. I was severely disappointed with the book, and not
the least concerned with LOLCats and Kitty Pidgin. The people who wrote the
book are a very knowledgeable group and sometimes their book works as a
reference, but overall doesn't seem add a lot to what's already in the
documentation, while being of no value to beginners whatsoever. 

 

It would be nice to have a good beginner book and a more advanced book. If
any of the more advanced programmers on this list would like someone to help
with writing the beginner book, don't hesitate to get in touch!

Before I make my judgments public, I'd first be curious to hear from

Follow Up: [Catalyst] Alternatives to DBIx:Class?

2010-04-19 Thread John Karr
Most of the responses to this thread seem to say that DBIC is worth the
effort. I looked at Fey:SQL and SQL::DB and concluded that they also require
some effort, and suffer (along with DBIC) from what is for me a huge issue
-- the documentation focuses on telling you how each piece works rather than
on how to drive the darn thing. 

At this point for everything I'm working on, I have the luxury that I can
write all of my joins and complex statements into a view or
stored_procedure, but in the real world programmers are too frequently
denied this, so even though right now I would like something that just
wrapped the DBI up in a manner that made it easy to write and keep the DRY
principle, it would be potentially more valuable to learn DBIC or Fey. DBIC
is the more widely adapted solution, while Fey seems to offer most of the
same capability with a syntax that draws on SQL (which is a lot of points in
its' favor), but has less momentum and lacks equivalents of some of the
helper scripts that are available for DBIC. 

So let me ask a follow up: What materials would you provide to an
Intermediate Level Programmer to help them learn either Fey or DBIC?
Materials could be working code, articles, things in documentation,
documentation for other things that happens to explain it well, chapters in
books, etc.

Afternote. There is a tutorial in Fey::ORM's documentation, but it is more
of a quick run-through. DBIx::Class has a better introduction in its'
documentation, but that hasn't helped me much. The tutorial Kennedy Clark
wrote for the Catalyst Manual was how I figured out Catalyst. Again
developer isn't my normal job title, I will probably never get paid for
knowing anything about ORM, time I spend learning it is only a benefit if it
gives me pleasure (not so far) or saves me time in the long run (the clock
is running the other way).

Absolutely!  When you are doing complicated reporting rollups
(multiple joins, subqueries, aggregate functions) that can be
arbitrarily tweaked, sorted, paged etc. then modifying with DBIC is
often just a case of tweaking a single hash declaration...

(Whereas updating a dynamic SQL codegen may well involve an hour of

because you forgot to add a space or comma that kicks in with some

Personally I think DBIx::Class is the biggest load of crock out there. 
It's much slower, awkward to use, time consuming to learn, and as soon 
as you try to do some complicated queries you'll end up dropping it 
anyway. ORMs simply cannot work in the long run:-

 With TT html is in html, while DBIx seperates the database from SQL, if I
 were capable of writing an ORM (which I am not) it would be much more like
 Template Toolkit. Also I'm primarily a sysadmin working on some volunteer

RE: [Catalyst] Alternatives to DBIx?

2010-04-17 Thread John Karr
I think there's a very important difference of approach, much as Template Tool 
Kit and Template Declare, radically different approaches, that are both far 
superior to the classic CGI Module. 

Working in raw DBI is the opposite of the DRY principle which underlies having 
a framework in the first place, so I am seeking an alternative. Just as 
Catalyst uses MVC, DBIx chooses ORM, but that paradigm is not the only way to 
be effective PERL==SQL glue. From the Manpage Fey::SQL looks like what I 
want: neatly wrapped and sweetened SQL, without the repetition and overhead 
inherent in working from DBI. I'm going to spend some time working with it and 
also with SQL::DB, when I have a more educated opinion I will share it. Both 
Fey and SQLDB are a nativist approach to SQL (much like TT is to html), and I 
would argue that in keeping the PERL paradigm of many ways to accomplish a 
task, the choice between a SQL-native DBI wrapper and an ORM wrapper should be 
up to the individual, the issue seems to be finding a worthy SQL-native wrapper.

In my own analysis the Time and Effort to learn DBIx is greater than the Time 
wasted writing repetitious DBI code, the time I've already invested on DBIx has 
shown that there is a better way than DBI, but for me it isn't DBIx.

 I'd say that rather than spending time studying SQL::DB, which I found

BTW, is there a comparison among the ORMs in Perl somewhere?
It would be interesting and definitely helpful for the ORM newbies.

[Catalyst] Redirecting Catalyst's Log to a File

2010-03-08 Thread John Karr
I'm having a problem with deploying a Catalyst application (I'm learning
Catalyst and this is the first application I've tried to put on the web, and
it works on my test machine which has a similar configuration to my ISP, but
just times-out at my isp returning nothing), and need to capture the logging
output from the fastcgi script to a file instead of the apache log. I
already tried plugging in Catalyst::Plugin::Log4perl::Simple, while it
redirects cgi and Catalyst's internal server to a file it does not work
under fastcgi. 

I would think to replace the Catalyst::Log method _send_to_log which just
dumps an array of messages to STDERR with one that dumped to a file instead.
Or capturing STDERR to a Filehandle might be an even easier hack. In a
simpler environment either of these methods should work, but with Catalyst
there are issues that are beyond me. One is persistence of a Filehandle
(either a log file or a captured STDERR), the other is overriding a method
of an ancestor object throughout the sequence of scripts. Finally there is
the question of insertion point.

Never mind, that's too simple. It breaks if users open up multiple pages unless

since presumably you don't want your user's expired sessions hanging around in 
their browser. 

Even simpler put a refresh tag in the page with a refresh a little over the 
session timeout value, then the site's handler for expired sessions can do the 
rest.

Why not return the datetime when the session expires with every page and
have a client-side js that does the redirect without hammering the
server?

 Using Catalyst::Plugin::Session with Session::State::Cookie.

 Would like to be able to poll server if the user's session has expired 
 WITHOUT extending the session itself.

 The objective is to have a javascript periodical executor check if a session 
 is expired and redirect user to a Your session has expired page if 
 appropriate. Could do it in javascript but would prefer doing it on server.

 Anyone tried this?

 Thanks in advance.

RE: [Catalyst] Check session expiry without extending it

2010-03-03 Thread John Karr
The more I think about this, the more problems I see with my idea, you need to 
either restrict your users to one browser window (possibly with a secondary 
page key of some sort) or have the refresh bounce to an alternate uri that 
refreshes the page without updating the server's session timer.
