I had the following in a file that was imported to a models.py:hrd_type = ContentType.objects.get_for_model(HttpReferrerDomain)The idea being that it can just set the var when it loads up and after that its always there. But this means for creating a fresh database, the db is ... more...

There is one in django.core.exceptions and one in django.forms.util Using that space age IDE Eclipse I have to say I'm enjoying how much time I've saved just going shift-command-O to organize and resolve all of my imports. But today I've just lost a few hours due to my ok-ing the wrong class. Quite mysterious it was, I raised a ValidationError (core exceptions one) in my form's clean() and watched as the try: except ValidationError: in django's full_clean() completely ignored my ... more...

MySQLdb is the python support bindings for MySQL. Not that the name would lead you to beleive that. Its sourceforge page calls it http://sourceforge.net/projects/mysql-python/ which makes more sense. you need setuptools, which you usually already have: sudo aptitude install python-setuptools You need MySQL-devel to compile, but its not called that, its called: libmysql++-dev on Ubuntu sudo apt-get install libmysql++-dev download MySQLdb itself from: http://sourceforge.net/projects/mysql-python/ # the version you download will be more recent tar xfz ... more...

When installing postgres a user will be created named 'postgres' with a password of '!!' which means "cannot login". But yet you need to login as that in order to run psql (the postgres db shell) to create other users and to create database templates. The solution is to first log yourself in as root (in your normal shell): su root (enter password...) then you will no longer be subject to password checks and you can login in as user ... more...

I'm enjoying Eclipse for Python Django development. The integrated lint check is great and has saved me much time already. Nearly automatic handling of imports is simply a life saver. Imports are the most time consuming and frustrating aspect of python development and I always wished they would just resolve themselves. With Eclipse and PyDev they do ! I dream of one day getting the debugger and integrated unit tests to work properly. It takes a while to get used ... more...

On one of my Linux Ubuntu servers the newish capistrano seemed to have broken. Wouldn't accept sudo authentication and showed what I typed in plain view. the fix: add this to the top of your capfile set :sudo, 'sudo -p Password:' the problem was that it was looking for the wrong text in the server's output to recognize that a prompt sequence was happening. a'ight, carry on more...

I wanted to do this: invoke Quicksilver, hit "." to enter text mode, enter a quick twitter-to-self and have it save that in a file named "{timestamp}.txt" without any further dialog. twitter-to-self within a few seconds with very low CPU disruption (for while I'm making music). Quicksilver has "append to file" but I wanted to do be safe with regard to newlines and I wanted the file to have a creation date that could be read later (when importing it ... more...

The error that Trac displays is "Clearsilver not installed" and yet clearsilver is clearly installed, but has a problem with python 2.5 The error sadly has been in Hardy's distribution for nearly 2 years, but newer Ubuntus should be fine. To quickly fix it on your machine, simply get this .deb directly: curl -O http://mathiasson.nu/debian/pool/main/c/clearsilver/python-clearsilver_0.10.4-1.0pm0_amd64.deb and install it thusly: sudo dpkg -i python-clearsilver_0.10.4-1.0pm0_amd64.deb On another note, Trac claims to have migrated to Genshi and requests it to be installed, but ... more...

PyQt-mac-gpl-4.5.1 has a bug in configure.py It will complain that the license is incompatible between itself and the "Desktop" version of Qt. The solution is to download a more recent snapshot (not the stable build at the top of the page, go further down the page). That compiles fine. update: no, sadly it does not install completely. see below. My eyes tend to glaze over when the license stuff comes up. I'm just playing around here, I'm not a lawyer. ... more...

Although there are many posts out there about django and cron jobs, none fully solved my problem.

Django 1.0 : now in URLS.py you get an automatic : admin.autodiscover() which replaces explicitly adding any admin.py in your modules. I had import admin in several of my ``__init__.py`` files, but this is no longer needed. The error message was confusing: localhost:~/Sites/sustainall/sustain crucial$ python manage.py shell Error: cannot import name Artist so it was some kind of a circular import. more...

MySQL will silently truncate UTF-8 strings at the first "damn foreigner" character or even m-dash or Microsoft Word Apostrophe. If you set it to strict mode via your my.ini file you can cause it to correctly throw the error "data truncated" which is still an incomprehensible error, but at least its not a silent error. I detest silent errors. Otherwise you will just wonder why your data got whacked. the solution: ============= Dump your database to a sql file, including ... more...

Firebug by default is disabled for all sites and you enable it site by site, which is very good. If you accidentally enable scripting debugging for gmail, you cannot get into gmail at all or Firebug/Firefox will lock up, the CPU will spike high and you have to force quit.

if you are working on your localhost, TextMate has a URL scheme to open a local file. http://manual.macromates.com/en/using_textmate_from_terminal.html so when an Exception happens in django you can click to open the file directly. this saves months of looking. these large code projects are all about going from one file to another. the quickest thing to do is just to hack the django. later I'll try to make it into a middleware or replacement template.

Developers do not like silent failures. I guess that "Designers" get all freaked out if they see a big messy error, they get frustrated and stop working for the day. So django has decided to silently ignore variable failures in templates: {{ user.email }} will produce nothing if there is no user but in your settings.py you can set a format string to be used in place of it: TEMPLATE_STRING_IF_INVALID = "!!!INVALID:%s!!!" !!!INVALID:user.email!!! more...

I was importing a bunch of posts, setting the text body directly to my posts post.body = maintext Trying to save them got an error "Data truncated for column..." which makes no sense because the body is a TextField which is a MySQL longtext type.

There is a useful django template tag : {% url app.views.viewfunc %} which is the same as: reverse('app.views.viewfunc') that should lookup through your ``urls.py`` to find the url pattern that matches that view. it should then return the formatted URL. this allows you to configure all of your urls in your ``urls.py`` file(s) and keep your templates this often does not work if your reg-ex is complicated eg. r'^track/?(?P.+)$' where there may or may not be a ``/`` and there ... more...

If a python file fails to compile, if you fix the compile error and then reload the page you still get an error telling you that the view was not found. ... more...

The new mac airport update breaks most audio programs. We now get nasty crackling and CPU spikes.

Since the recent Logic upgrade (7.2) the audio now cuts out occasionally with a loud DC thump. This happens often when enabling record ! Even while play is already happening, simply hitting record causes all audio to cut out with a rude thump. It can also happen just when playing.

The new (July 2007) MacBook Pros have a problem with their wireless cards. The new cards are 802.11g and these have problems with slow data when connecting with some wireless hubs eg.

This is quite slick ... you buy a new mac, connect the old one via firewire cable and you get zapped over. but... especially if you are transitioning from PPC to Intel, I would advise against this.

Reaktor doesn't freeze very well. Often after freezing the track there is no audio in the file, and sometimes the controllers appear not to have been chased correctly.

You can't make Logic channel strips with reaktor patches and expect them to recall exactly. I would expect the channel strip to save all memory of all plugins in the strip. For Logic plugins they do : you can edit all your plugins freely and then just save the whole strip. (but be careful with EXS24) With Reaktor patches it doesn't work. That would be nice ... its much faster to recall a channel strip then to open reaktor and ... more...

Sound Designer I file format is the original Digidesign sound file format first released in 1985. It is widely used and supported as evidenced by the many CD ROM discs with sound effects stored in this format. It is primarily used to store mono 16 bit short duration (on the order of seconds) audio samples. We recommend that you support this format for short sounds, but that you use Sound Designer II format as a primary format due to its ... more...
