You don't need a SSL middleware. Just add to your Apache
configuration:

  SetEnvIf X-Forwarded-SSL on HTTPS=1

Apache/mod_wsgi will allow overriding of wsgi.url_scheme based on
HTTPS variable. The HTTPS variable can be set to 'On' or '1'. Case
ignored in comparison.

Thus, you can use mod_setenvif to check for header being set and what
value and then set HTTPS.

SQL query with complex WHERE clause

Hi All,

I don't seem to find good source to help me write a complex where condition
in the django.

The where condition is generic boolean clause built on top of literals. The
literal are just == or != check on a single field.
for example ((field1 == 2 and field2 != 5) or field3 == 6).
another example ((field1 > 1 or field1 < -3) and (field2 != "comment")) or
field3 == "django"

I think it should be writable in the django queryset but I can't seem to
formulate it in generic format.

Any pointers or guidance will be great.

thanks

it ended up being an incorrect working directory. I had to give the

Karen,

Thanks for the thorough explanation. I really appreciate it. What I
took from it is that if I'm using a ModelForm, Django should return a
validation error for a duplicate value. However, for my scenario, I
*am* using a ModelForm. Here's a snippet:

### Model ###
class School(models.Model):
    url = models.SlugField(max_length=50, unique=True)
    name = models.CharField(max_length=255)
    ...

### Form ###
class SchoolForm(ModelForm):

    class Meta:
        model = School
        fields = ('url', 'name')

### View ###
def new_school(request):
    if request.method == 'POST':
        form = SchoolForm(request.POST)
        if form.is_valid():
            form.save()

new_school craps out with an IntegrityError exception any time I have
a duplicate value. Any additional thoughts?

Looking at the code, I don't see how the spell_check function could
throw that Error. I have just one idea: can you move the last return
statement:

    return HttpResponse(simplejson.dumps(output),
        content_type='application/json')

into the try block, just after the assignment of the output variable:

        output = {
            'id': id,
            'result': result,
            'error': None,
        }
        return HttpResponse(simplejson.dumps(output),
            content_type='application/json')

Regards,

Joost

*** DoesNotExist:

What on earth could be causing this? According to cleaned_data, the
user field is valid. Why the heck is the flight being created not
having a valid user?

The form in question is coming from a heavily customized modelformset
where the queryset parameter is set to
Flight.objects.get_empty_query_set(), and extra parameter is set to
20. So it's essentially 20 blank fields. When I use this same
modelformset with a full queryset and extra set to 0, the formset
saves just fine.

The Flight form looks like this:

###
class FlightForm(ModelForm):
    user =     forms.ModelChoiceField(queryset=User.objects.all(),
widget=HiddenInput)
    [...]
###

and in the view I have this:

###
    if request.POST.get('submit'):
        post = request.POST.copy()
        for pk in range(0, profile.per_page):
            if post["form-" + str(pk) + "-date"]:
                post.update({"form-" + str(pk) + "-user": str
(request.user.pk)})
            else:
                post.update({"form-" + str(pk) + "-user": u''})

        formset = NewFlightFormset(post,
queryset=Flight.objects.get_empty_query_set())

        if formset.is_valid():
            import pdb; pdb.set_trace()
            formset.save()
###

any ideas?
