How to write to a FileField?
Ok, I've been looking all over the docs for a solution to this, but
there's a lot of documentation for the FileField, just not on how to
use it…
I have a model that looks like this:
class Import(models.Model):
complete_data = models.FileField(upload_to='import_data/complete/
%Y/%m/')
partial_data = models.FileField(upload_to='import_data/partial/%Y/
%m/')
user = models.ForeignKey(User, blank=False, null=False)
I would like to do something like this:
import_data = Import.objects.create(user=user_object)
file_name = hashlib.sha1(user_object.username + str(time.time
())).hexdigest()
import_data.complete_data.name = file_name
import_data.complete_data.open('w')
import_data.complete_data.write(pickle.dumps(pickles))
import_data.complete_data.close()
But it seems these attributes are read-only… So, the golden question
is, how do I pick a file name and write to a FileField?

Re: Django pluggable adressbook/mini-CRM?
Yeah, okay. I think I'll keep it simple until further notice, with just a client name, phone number and e-mail.

Django pluggable adressbook/mini-CRM?
Hi there, I'm working on a small time tracking app (http://github.com/mikl/djime/ tree/master – in case anyone is interested), and I'm looking to track time spent on clients, projects and tasks, and currently I'm on the lookout for some sort of address book or CRM that I could utilize instead of writing my own.

Re: Strange UnicodeDecodeError in template
Thank you Karen, that was it.
I wonder if this is a bug and should be reported...
The origial error was an error in the {% cycle %}-tag...

Strange UnicodeDecodeError in template
I have a bit of a problem with a project I'm creating. I get an UnicodeDecodeError from some of the template code. The traceback is here: http://dpaste.com/24285/ It tries to decode the title field from unicode into ascii, but I cannot seem to understand why... I have dpaste'd the code in question. Template: http://dpaste.com/24284/ Model (where the get_task function is): http://dpaste.com/24281/ View (I suppose that's rather irrelevant): http://dpaste.com/24286/ Since the code is open source, you can browse it in its entirety here: http://codebrowse.launchpad.net/~mikl/kaplan/kaplan.dev/files If anyone can figure this out, you will have my eternal gratitude Thanks to Magus- in #django for trying - if you are reading this, I changed the part you pointed out to use Django's slugify function instead of str().lower(), but that wasn't it, sadly.

Re: Getting the right data to the template
Thank you for your input, Malcolm. I've made up something based on
your suggestions in revision 56:

Sorry for missing your last name in the commit message, but I was off-
line when I committed this (7 hour train journey, what would I do

Getting the right data to the template
I have a bit of a problem - I'm creating a GTD-focused task management app for Django, mainly for my own benefit, but it's open source if any one cares. I've been trying to implement a taxonomy system like the one Drupal uses. Only problem is that I find it difficult to get the right data out into the template system. As an example, I have a list of Task objects, which is supposed to be displayed to the user. These Task objects all have Term object associated with them (ManyToMany). The Term objects belong (ForeignKey) to a Vocabulary object. I want to get the Term objects by their Vocabulary so I can display them in different columns. Lets say I have a Task object called 'Fix the apache configuration on xyz server', which has the Term objects 'Urgent' (from the Priority Vocabulary) and 'Work' (from the Context Vocabulary). Currently, I have a bit of a kludge where I've put a refresh method on the Task object that generates a dictionary with vocabulary names as keys and as value a string containing a comma-separated list of all the terms from that Vocabulary associated with the Term object in question. I would like to be able to access the Term objects directly in the template, so I could get the absolute URL for them in the "right" way or if that's not feasible, some other solution, because I need the aforementioned string to have links to the Term objects in question... You can see the model code in question here: http://codebrowse.launchpad.net/~mikl/kaplan/kaplan.dev/annotate/mikkel%40hoegh.org-20071015103825-kmr72968yz91serq?start_revid=mikkel%40hoegh.org-20071017164032-iz6zlgj3m735a5qe&file_id=svn-v2%3A1%4005d49af5-ae19-0410-aa10-c28341cc0fd9--src%2fdanet%2ftodo%2fmodels.py Checkout instructions etc. here: https://code.launchpad.net/~mikl/kaplan/kaplan.dev Any input will be greatly appreciated.
