Re: Binary Post Data to ImageField
As I know Django can not save binary data with it's default orm, you can try
to select another orm like sqlalchemy, or you can try to
modify the orm to make it can save binary data.

Got error when update object
Hi all,
I'm writing a small app, and get an error when trying to update the
object, the error message is
'QuerySet' object has no attribute '_meta'. and It shows that I made
some mistake on this line:
form = ProjectForm(instance = projectInstance). But I don't know where
am I wrong. The below is my code in views.py.
@login_required
def edit_project(request, project_id = None):
if project_id == None:
projectInstance = Project()
else:
projectInstance = Project.objects.filter(id =
project_id).filter(Q(creater = request.user) | Q(administrator =
request.user))
if projectInstance.count() == 0:
return HttpResponseRedirect('/edit/fail/')
if request.method == 'POST':
form = ProjectForm(request.POST, instance = projectInstance)
if form.is_valid():
project = form.save(commit = False)
if project.creater is None:
project.creater = request.user
else:
project.creater = project.creater
project.save()
form.save_m2m()
return HttpResponseRedirect('/')
else:
form = ProjectForm(instance = projectInstance)
variables = RequestContext(request, {'form': form})
return render_to_response('add_project.html', variables)
My environment is: UBUNTU910, Django 1.1.1. Anyone can help me? Thank you
very much!

Re: Problem about write data into the DB
HI Bruno, Thank you for your answer. The reason I choose setup the whole environment is I need setup them in a virtual machine and send this virtual machine to my friends to test it, they are not familiar with django, they just want to open the web browser and test the site. And I also want to get a try, actually this is my first time to deploy a django project, I need chance to exercise. The HTTP 500 error has solved just now. Yes, you are right. the apache account hasn't the r/w access to the DB file, I modified the rights of the DB file and my site works well now!

How to access blob type data in django
Hi all, I'm trying to setup a picture library website using django. What I want to do is store the picture into the database directly and access the db to show them in the html file when user view in the web. I have read some documents and tutorial about the django but what I have learned is just store the picture files in my hard disk not in the db. And it looks that the django Model field hasn't such a type to deal with the binary data like blob data type in the database. So can django meet my request? If django can do it and how can I do it with django?
