In test server it is working. But production gives this traceback:
what different? And what does that error mean?
Different is only in python versions. In test server it is 2.6.5 and production 2.5.2. How can I get rid of this error with out changing version?

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-10: ordinal not in range(128)
After some time thinking and testing. I notice that error shows only when i do this:
med,created=RemMedia.objects.get_or_create(index=program.Id+50000000, defaults=fields)
After some more time of thinking end testing, i found the error. It is in dictionary fields. There is one variable which i get from BeautifulSoup the code looks like:
soup=BeautifulSoup(program.Description.encode('utf-8'))
name=soup.find('div',{'class':'head'})
fields=dict(
name=name.string,
description=program.Description.encode('utf-8'),
program_name=program.Name.encode('utf-8'),
program_date_time=program.RealDateTime,
topic_data_time=program.RealDateTime,
topic_tag='',
created=program.Updated,
media=media
)
The problem is with variable name in fields dictionary.
Question remain : How to convert it so it will not gives an error?

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-10: ordinal not in range(128)
Do you have a character with an ascii value > 128? Probably an accented letter.
http://www.asciitable.com/

If the problem lies within the database, it's probably a setting. If it's within the python code, you may try placing this line at the top of your python file that deals with the string.
# coding:utf-8

From googling a bit I get the feeling that this is related to ASCII / UTF8 encoding but I don't understand how that applies to my situation. I am dealing with a binary file. In fact it is a Java jar file but that should be pretty much a zip file as far as I understand. What is going on here and what am I doing wrong?
this is related to language translation. when non ascii filenames with the django storage system. So add following lines in your apache envvars
export LANG='en_US.UTF-8'
export LC_ALL='en_US.UTF-8'

UnicodeDecodeError after restart on server

I've implemented a product called Odoo/OpenERP and recently performed a restart after changing some strings in multiple files.
These strings contained standard characters with no accented characters. After the restart, any access to the site results in the below:

I've checked the files I've made changes to, but these seem fine.
Does anyone know where I can start to debug this issue? I'm relatively new to Python and debugging/understanding this trace is something I'm not familiar with.
So you have to use unicode strings because when your string is processed, somewhere it needs to use it as unicode, and it fails because the string type is str. You can make it into unicode by
mystring = unicode(mystring, 'utf-8')
This will change the type of your string from str to unicode

silently truncating django model char field

I'm trying to do a mass import of data into an existing database. Sometimes the string fields in this other database contain strings that are larger than the field I'm importing them into. I'm OK with this, I'd like the system to just silently truncate, but I'm getting a warning which then also halts execution.
Since this is a live database, I'm running my code via "manage.py shell" and and when I call the import routine it halts after the first string field it encounters that's too long. Oddly it DOES insert it into the database truncated as I expect, but then exits the for loop.
Thanks!

How to store output of os.urandom(8) in CouchDB?

I am trying to store some cryptographic data in couchdb. I need to store a salt and encrypted password in couchdb. The salt is generated using python's os.urandom(8) and the sample output of that would look like:
'z/\xfe\xdf\xdeJ=y'
I'm using python-couchdb api to store the document. When I try to save the document I get:

Encode it as either base64 or as hex before saving, or save it in a binary field.
Encode the output of urandom in base 64 like this:
os.urandom(8).encode('base64')
As per the example in this thread
