Treebeard Administrator at Django

Question

I installed Treebeard in Django and everything seems to have gone well. I tried to configure the admin system, and I see that my models are represented in the admin interface. However, when I try to add new data using the admin interface, I get the following error in my template. The code is still working fine and I checked my DB and the data seems to be inserted correctly. However, the view does not seem to load properly. Any idea what causes this?

The exception am get is:

Rendering exception showing: unsuccessful key search [request] in u '[{\' action_index \ ': 0, \ block \': ,,,]>}, {\ 'block \': ,,]> ,,, \ n \ '>,]>,]> ,,]> ,, \ n \'>> ,,,,,] →,]>, \ n \ '>]>}, {\' cl \ ':, \ 'root_path \': None, \ 'actions_on_bottom \': False, \ 'title \': u \ 'Select an album to modify \', \ 'has_add_permission \': True, \ 'media \' :, \ 'is_popup \ ': False, \' action_form \ ':, \' actions_on_top \ ': True, \ app_label \': \ 'gallery \'}, {\ 'MEDIA_URL \': \ '\'}, {\ 'LANGUAGES \ ': ((\' ar \ ', \' Arabic \ '), (\' bn \ ', \' Bengali \ '), (\ bg \', \ 'Bulgarian \'), (\ 'ca \' , \ 'Catalan \'), (\ cs \ ', \'Czech \ '), (\' cy \ ', \' Welsh \ '), (\ da' ', \' Danish \ '), (' de ', \' German \ '), (\' el \ ' , \ 'Greek \'), (\ 'en \', \ 'English \'), (\ 'es \', '' Spanish ''), ('et', '' Estonian ''), (\ es-ar \ '', '' Argentinean Spanish ''), ('' eu '', 'Basque' '), (\' fa \ ',' Persian '), (\' fi \ ', \' Finnish '), (\' fr \ ', \' French \ '), (\ ga \', \ 'Irish \'), (\ gl \ ', \' Galician \ '), (\ hu \, "Hungarian "), (" he "," Hebrew "\ '), (\ hi \', \ 'Hindi \'), (\ hr \ ', \' Croatian \ '), (\' is \ ',' ' Icelandic), (\ it \ ', \' Italian \ '),(\ 'ja \', \ 'Japanese \'), (\ 'ka \', \ 'Georgian \'), (\ ko \ ', \' Korean \ '), (\ km \', \ 'Khmer \ '), (\ kn \', \ 'Kannada \'), (\ lv \ ', \' Latvian \ '), (\ lt lt', "Lithuanian"), ("mk", "Macedonian") , ("nl", "Dutch"), ("no", "Norwegian") (\ 'pl \', \ 'Polish \'), (\ 'pt \', \ 'Portuguese \'), (\ 'pt-br \', \ 'Brazilian Portuguese' '), (\' ro \ '', '' Romanian ''), (\ 'ru \', \ 'Russian \'), (\ 'sk \' , \ 'Slovak \'), (\ 'sl \', \ 'Slovenian \'), (\ 'sr \', \ 'Serbian \'), ('sv \', \ 'Swedish \'), ( \ ta \ ', \' Tamil \ '), (\ te, \'Th \ ', \' Thai \ '), (\' tr \ ', \' Turkish \ '), (\' uk \ ', \' Ukrainian \ '), (\\' zh-cn \ ', \ 'simplified Chinese \')), (\ zh-tw \ ', \' Traditional Chinese \ ')), \ LANGUAGE_BIDI \': False, \ LANGUAGE_CODE \ ': \' en-us \ '}, {}, {\ 'perms \' :, \ 'messages \': [], \ 'user \':}, {}] '

Model for nested sets:

from django.db import models
from treebeard.ns_tree import NS_Node

class Category(NS_Node):
    name  = models.CharField(max_length=255)

    def get_absolute_url(self):
        return ('node-view', ('ns', str(self.id),))

    def __unicode__(self):
        return u'NS_Post %d: %s' % (self.id, self.name)

class Meta:
    verbose_name = 'Nested Set Tree Post'

    # when adding a custom Meta class to a NS model, the ordering must be
    # set again
    ordering = ['tree_id', 'lft']

---

Contact List Model:

from django.db import models
from treebeard.al_tree import AL_Node

class Category(AL_Node):
    name  = models.CharField(max_length=255)
    parent = models.ForeignKey('self',related_name='children_set',null=True,blank=True,db_index=True)
    node_order_by = ['name']

    @models.permalink
    def get_absolute_url(self):
       return ('node-view', ('al', str(self.id),))

    def __unicode__(self):
        return self.name

I tried to fix it with

TEMPLATE_CONTEXT_PROCESSORS = 'django.core.context_processors.request'

in settings.py, like ml, it was suggested on March 27 at 23:16. Now i have an error

Exception Type:     ValueError
Exception Value:    Empty module name
