What is the preferred way of storing generated content into file
models?
class Chart(models.Model):
xml = models.FileField(upload_to='charts')
...
I would like compute the image on the fly, using some data in the
database. How should I store the generated data? How should I use File
Thanks for the quick reply. I have had request.FILES in there; my
problem was I misspelled the field name in the template.
My question is still the same though; is this the right way to work
with ImageField (FileField)? I still feel this is awkward. One has to
call methods on the model instead
I used to store images in the database. Now I want to store them on a
disk. I have the following model:
class User(models.Model):
image = modes.ImageField(upload_to='userimages')
...
then, I have a new form like
class Information(forms.Form):
image =
What is the best way of adding query parameters (aka GET parameters)
to a URL?
return HttpRedirect(reverse('animal-search') + '?q=%s=%d' %
(animal.name, current_page))
seems awkward to me (not to mention escaping the name). How can I
avoid creating query parameters manually? Or, should I avoid
That is actually the same :-) However neither
Author.objects.filter( Q(name='Jiri Barton') |
Q(article__title__icontains='revealed'))
works. :-(

I have but to agree with both statements. Let's leave it the way it
is.

Another thing. I don't know if that's legal or not but I'd also need
to check the query:
self.client.post('/usermanagement/users/create/', {
'firstname': 'Sherlock',
'lastname': 'Holmes',
})
redirects to
/usermanagement/users/filter/?edit=1
(I use some search
I could live with doing multiple checks. In fact, I may want to check
every URL in the redirecting chain to make sure the flow is just what
I wanted.
Then, I can just hard code the URLs in the chain:
response = self.client.get('/page')
self.assertRedirects(response, '/first/') # no need to
Thank you Russ, that has fixed the problem.
I have a problem with the fix though; what if there were multiple
redirects? This just happened when I jumped to use your fix today:
/usermanagement
redirects to
/usermanagement/
which redirects to
/usermanagement/users/
in my application. I
You can use the YAML serializer until this is fixed. It worked for me.
You will have to install PyYaml first (http://pyyaml.org/) - or
easy_install pyyaml.

Why does assertRedirects of TestCase succeeds only if the response
code is 302? One would think any 3xx should do - they are *redirects*
at all. At least, I would think 301 were okay because that is what
django.views.generic.simple.redirect_to generates.
How am I supposed to think about that?
Why, I thought Person.position would be the straightforward way. I
mean that was the first thing that came to my mind - I have a class

how do I check if a variable is None in a template? The following do
not work...

list; then, I want to tell the user - say
