• Django : debugging templatetags

  - by interstar

  How on earth do people debug Django templatetags? I created one, based on a working example, my new tag looks the same to me as the existing one. But I just get a 'my_lib' is not a valid tag library: Could not load template library from django.templatetags.my_lib, No module named my_lib I know that this is probably because of something failing when defining the lib. But how do I see what's going on? What do you use to debug this situation?

• Encoding::UndefinedConversionError from email body

  using mail for ruby I am getting this message: mail.rb:22:in `encode': "\xC7" from ASCII-8BIT to UTF-8 (Encoding::UndefinedConversionError) from mail.rb:22:in `<main>' If I remove encode I get a message ruby /var/lib/gems/1.9.1/gems/bson-1.7.0/lib/bson/bson_ruby.rb:63:in `rescue in to_utf8_binary': String not valid utf-8: "<div dir=\"ltr\"><div class=\"gmail_quote\">l<br><br><br><div dir=\"ltr\"><div class=\"gmail_quote\"><br><br><br><div dir=\"ltr\"><div class=\"gmail_quote\"><br><br><br><div dir=\"ltr\"><div dir=\"rtl\">\xC7\xE1\xE4\xD5 \xC8\xC7\xE1\xE1\xDB\xC9 \xC7\xE1\xDA\xD1\xC8\xED\xC9</div></div>\r\n</div><br></div>\r\n</div><br></div>\r\n</div><br></div>" (BSON::InvalidStringEncoding) This is my code: require 'mail' require 'mongo' connection = Mongo::Connection.new db = connection.db("DB") db = Mongo::Connection.new.db("DB") newsCollection = db["news"] Mail.defaults do retriever_method :pop3, :address => "pop.gmail.com", :port => 995, :user_name => 'my_username', :password => '*****', :enable_ssl => true end emails = Mail.last #Checks if email is multipart and decods accordingly.

Replacing UTF-8 with ASCII-8BIT gives a similar error. I get the same result when using plain_part for plain email messages. I am handling emails from one specific source so I can put html_part with confidence it's not causing the error. To make it extra weird Subject in Arabic is rendered perfectly. What encoding should I use?

• How to incorporate an xml fragment into tomcat's server.xml

  - by rmarimon

  I'm doing a distribution of tomcat for a many servers and in each of these servers the realm is going to be different. I would like to have a file /etc/tomcat/realm.xml containing the realm for that installation and have the file /var/lib/tomcat/conf/server.xml import it directly. I've tried with Xinclude without luck and I'm about to resort to sed to the import when running /etc/init.d/tomcat. Is there a better way to do this?

• Py2exe, PyQt4 and Postgre Driver (QPSQL)

  - by Marshall

  Hi, I`m trying to freeze my application using Py2exe. My app uses PyQt4 and it apparently works fine with py2exe. But once I`ve uninstalled PyQt, it shows the following error: QSqlDatabase: QPSQL driver not loaded QSqlDatabase: available driver: QPSQL7 QPSQL Which doesn't make sense at all. If PyQt4 is still installed, it works just fine. This is my py2exe parameters: data_files = [ ('sqldrivers', [ 'C:\Python26\Lib\site-packages\PyQt4\plugins\sqldrivers\qsqlpsql4.dll' ]) ] setup(console=["delivery.py"], options={"py2exe" : {"includes" : ["sip", "PyQt4.QtSql", "PyQt4.QtWebKit", "PyQt4.QtNetwork"]}}, data_files=data_files)

• How do I add older versions of code into a Subversion repository as tagged versions

  - by TheoJones

  When we finally started using source control, old versions of code were added into the SVN in their own discrete folders, so I ended up with root \libv4 \libv4.2 \lib4.3 \lib5 What I would like to get to is having these older versions of the code as tagged versions inside the repository, like this: root \lib \tags \v4 \v4.2 \v4.3 \v5.0 \trunk how would I go about doing this? I'm using Tortoise SVN on the client side, and visualSVN server at the back.

• MooseX::Types declaration issue, tight test case :)

  - by TJ Thompson

  So after an embarrassing amount of time debugging, I've finally stripped this issue ([http://stackoverflow.com/questions/4621589/perl-moose-typedecorator-error-how-do-i-debug][1]) down to a simple test case. I would humbly request some help understanding why it's failing :) Here is the error message I'm getting: plxc16479 $h2/tmp/tmp18.pl This method [new] requires a single argument. at /nfs/pdx/disks/nehalem.pde.077/perl/5.12.2/lib64/site_perl/MooseX/Types/TypeDecorator.pm line 91 MooseX::Types::TypeDecorator::new('MooseX::Types::TypeDecorator=HASH(0x655b90)') called at /nfs/pdx/disks/nehalem.pde.077/projects/lib/Program-Plist-Pl/lib/Program/Plist/Pl.pm line 10 Program::Plist::Pl::BUILD('Program::Plist::Pl=HASH(0x63d478)', 'HASH(0x63d220)') called at generated method (unknown origin) line 29 Program::Plist::Pl::new('Program::Plist::Pl') called at /nfs/pdx/disks/nehalem.pde.077/tmp/tmp18.pl line 10 Wrapper test script: use strict; use warnings; BEGIN {push(@INC, split(':', $ENV{PERL_TEST_LIBS}))}; use Program::Plist::Pl; my $obj = Program::Plist::Pl->new(); Program::Plist::Pl file: package Program::Plist::Pl; use Moose; use namespace::autoclean; use Program::Types qw(Pattern); # <-- Removing this fixes error use Program::Plist::Pl::Pattern; sub BUILD { my $pattern_obj = Program::Plist::Pl::Pattern->new(); } __PACKAGE__->meta->make_immutable; 1; Program::Types file: package Program::Types; use MooseX::Types -declare => [qw(Pattern)]; class_type Pattern, {class => 'Program::Plist::Pl::Pattern'}; 1; And the Program::Plist::Pl::Pattern file: package Program::Plist::Pl::Pattern; use Moose; use namespace::autoclean; __PACKAGE__->meta->make_immutable; 1; Notes: While I don't need the Pattern type from Program::Types in the above code, I do in other code that is stripped out. The PERL_TEST_LIBS env var I'm pulling INC paths from only contains paths to the project modules. There are no other modules loaded from these paths. It appears the MooseX::Types definition for Pattern is causing problems, but I'm not sure why. Documentation shows the syntax I am using, but it's possible I'm misusing class_type as there isn't much said about it. Intent is to be able to use Pattern for type checking via MooseX::Params::Validate to verify the argument is a 'Program::Plist::Pl::Program' object. I've found that removing the intervening class Program::Plist::Pl from the equation by directly calling Pattern-new from the tmp18.pl wrapper results in no error, even when the Program::Types Pattern type is imported.

• json problems with making a ruby on rails application

  - by Prince Merdz

  So I'm using Bitnami to learn Ruby on Rails. I have also previously tried the manual installation for ruby and rails and was met by the same problem so I thought I should try first the easy package deal of Bitnami. Anyway my problem with json is that it causes the bundle install to fail. First the auto bundle install that rails new does fails because of an ssl error. Which is easily solved by changing the source in the gemfile which is https to http. However when I try to bundle install it does another error when it tries to install json.
