Hi all
I have a problem I have been struggeling with for a while.
I have two models:
InfoProxy and Permission
A InfoProxy can have several Permissions
class Permission(models.Model):
info_proxy = models.ForeignKey(InfoProxy,
related_name='permissions')
permission_type = models.CharField(maxlength=1,
choices=PERMISSION_CHOICES)
usergroup = models.ForeignKey(UserGroup)
class InfoProxy(models.Model, UrlItem):
"""
A proxy pointing to a (Info)Item
"""
info_type = models.ForeignKey(ContentType,
related_name='infoproxies')
info_id = models.PositiveIntegerField()
info_item = generic.GenericForeignKey(ct_field="info_type",
fk_field="info_id")
render_type = models.ForeignKey(ContentType,
related_name='render_infoproxies', blank=True, null=True)
render_id = models.PositiveIntegerField(blank=True, null=True)
render_item = generic.GenericForeignKey(ct_field="render_type",
fk_field="render_id")
created = models.DateTimeField('date created')
modified = models.DateTimeField('date modified')
owner = models.ForeignKey(User)
language_code = models.CharField(maxlength=20)
rank = models.IntegerField( blank=True, null=True)
grade = models.IntegerField( blank=True, null=True)
objects = InfoProxyManager()
I want to query for all object a user has permission to read depending
on groups (code below)
This code works without any problems on developer server. On
mod_python however I (sometimes) get the below error.
If I hit refresh in the browser, it usually works.
I have tried several things like:
All imports are with full paths
Classes put in site-packages
(Maybe something is wrong when loading classes)
I have checked so at least one permission exist on every InfoProxy
Anyone have had a similar problem?
Any hint that can help me try other options?
Any help is very much appreciated.
