Run the two commands:

$ dd if=/dev/zero of=/swapfile bs=1024 count=1048576

$ mkswap /swapfile

Then edit /etc/fstab and add this line:

/swapfile none swap sw 0 0

Problem:  When uploading images to Satchmo I got this error message: "Upload a valid image. The file you uploaded was either not an image or a corrupted image." even with valid JPEG files.

To test the Python Image Library (PIL) I’d  executed this code on python console:

from PIL import Image
file = open("/tmp/logo.jpg")
image_test = Image.open(file)
image_test.load()

what output:

<PixelAccess object at 0x37dce100>

This is ok, but when I’d run the same code inside a Django view I got the error "decoding error when reading image file".

I checked the Python Path and it was the same for both console and Django Application.

After looking on google I discover a post from Peter Schoenster on “Django-Photologue“  wiki page saying he had the same problem and discovered that python shell was using one version of libjpeg and Apache was using other. (He, as me had two version of this library on the system). He discovered it using the command

# lsof | grep libjpeg

I just remove the old libjpe62 from my system using:

# apt-get remove libjpeg62

And everything works !

When I tried to install the Library PIL on a Ubuntu 8.04 where I had installed  Python 2.6 I got:

I’d founded the file ‘tk.h‘ on ‘/usr/include/tcl8.4‘ and after a look at the setup.py file I changed the line number 41 from:

TCL_ROOT = None

to

TCL_ROOT = “/usr/include/tcl8.4″

Now you can run your ‘python setup.py install’ again and get PIL working!

Note: You may perhaps have to install the tk-dev and tcl-dev packages before running the setup.py. I’d already had these packages, so I’m not sure about it.

On Ubuntu run:

apt-get install tk-dev tcl-dev

Satchmo is a great shopping cart application that uses Python and Django. If you are looking for this kind of application it worth a look.

One of the best point of Satchmo is how easy and beautiful is to customize your application. You can create customized product model without touch the base Satchmo models. It’s a great feature, that make easy to apply future Satchmo updates.

You can learn how to create a custom product in JuanjoAlvarez Blog.

I followed the instructions but get the error:

Wed, 12 Aug 2009 11:57:17 configuration DEBUG SettingNotSet: PRODUCT.PRODUCT_TYPES
Traceback (most recent call last):
File "./manage.py", line 27, in
execute_manager(settings)
.
.
.
.
raise SettingNotSet('%s config group does not exist' % group)
livesettings.models.SettingNotSet

SOLUTION: After apply a grep in the Satchmo code for “PRODUCT_TYPES” I figured out my mistake: My package was named product: the same name of the Satchmo product application. So it was overriding the framework application.

Thank god Satchmo is a Open Source project!

Installing PostgreSQL from sources is a very easy and grateful task. It allow you to customize a lot of stuffs in your database server (I really appreciate the option of choose where to install my softwares, but this is not all).

You can get the PostgreSQL sources at http://www.postgresql.org/ftp/source/. I got the sources for the version 8.3.7, since it’s the latest stable version, so far.

Download psycopg2 at http://initd.org/pub/software/psycopg/

To install  (I’m using the version 2.0.10) you need to run two commands:

# python setup.py build

and after the build is complete:

# python setup.py install

Well, but it’s not so easy if you do not have the dependencies already installed.In my case I got errors like:

NameError: global name ‘w’ is not defined psycopg2

or

error: Setup script exited with error: command ‘gcc’ failed with exit status 1

To solve this I have to install the libpq-dev library and the python development package:

# apt-get install libpq-dev

# apt-get install python2.5-dev

After that I just run the usual python setup.py install and all done.

Problem: If we change the default SSH port Zimbra features like Mail Queues stop working.

Workaround:
