Mod_python on django and debug variable

Question

Hi,

I have a problem with my django application. On django developer server its work perfect, but when I switch it to apache something strange happening. Lets check the code:

class Criteria(models.Model):
    district = models.ManyToManyField(District, verbose_name=u"Województwo", blank=True)
    respondents = models.ManyToManyField(User, verbose_name=u"Respondenci")

    def getData(self):
        # return self.district.all() - good
        return self.respondents.all() # error

When I set in settings.py debug variable to true (DEBUG=True) nothing bad happens. But when I switch it to false (DEBUG=False) I get an error when I call that method.

MOD_PYTHON ERROR

Any ideas ?

Answer 1

I would look into this block node "loginBox" and the required parameter 'user' if I were you.
