After a few hours of bug hunting, I found out why my current translation is not loaded. I think, there is a problem with your directory structure:
For each app django loads the translations from the locale subdirectory. In my case, I only load the categories.editor app - so I only get the translations in categories/editor/locale. The problem is that categories.editor relies on stuff from the categories folder and those translations won't get loaded.
So did I get something wrong or should CategoryBase rather be a model in categories.editor (or something like categories.common) in order to be translated?
short version
=> CategoryBase and Category should not be in the same app
current workaround
If you only want categories.editor put categories and categories.editor in INSTALLED_APPS and then unregister the Admin for Category:
admin.site.unregister(Category)
I have read about the lazy connection at the bottom of this link
https://django-categories.readthedocs.org/en/latest/getting_started.html#connecting-your-model-with-django-categories
I have also read about the actual steps to make it happen in this link
https://django-categories.readthedocs.org/en/latest/registering_models.html#registering-models
So I put this inside my settings.py
CATEGORIES_SETTINGS = {
'M2M_REGISTRY': {
'articles.Blog': 'categories',
}
}
when I run "python manage.py add_category_fields articles" I get this error:
ImportError: cannot import name MODEL_REGISTRY
I also tried putting the following into init.py
from categories import registration
from articles.models import Blog
registration.register_m2m(Blog)
But nothing happens.
The bottom of this link https://django-categories.readthedocs.org/en/latest/registering_models.html#registering-a-many-to-many-relationship shows sample code using categories.register_m2m, but categories module doesn't have register_m2m, it's inside registration.py. I doubt the accuracy of the document.
I have custom category subclassed from CategoryBased
Using template tags on such a category fails because the tags expect either a Category instance or a string. Is there any reason for the template tags to check for a Category instance instead of CategoryBase ?
Using markup like:
'ADMIN_FIELDSETS': {
'appA': None,
'appB': 'Catigoricals',
'appC': {'name': 'Cats', 'index': 2}
}
It allows for the default behavior if not listed (admin field set called categories appended to their admin class).
appA would not get any field set
appB would get a field set appended to the admin class called 'Catigoricals'
appC would get a field set named 'Cats' inserted at index 2 of their field sets in their admin class.
As migrations 0009 and 0010 where not only renamed but also changed in content, upgrading from 1.0.2 to 1.0.3 is not possible.
Backward migration to 0008 in 1.0.2 before upgrading is not possible due to restrictions on CategoryRelation.story field; forward migrations fails as <categories: 0010_changed_category_relation> migration does not exists anymore, and if you ignore that with --delete-ghost-migrations categories:0010_add_field_categoryrelation_category fails as categories_categoryrelation already exists (from 'old' 0010).
Any solutions?
I get this error when I try to access the admin list page. Add page works fine though.
On line 14 in views.py
says
@cache_page(CACHE_VIEW_LENGTH)
key_prefix is not sent in. I thought it would default to the one in settings
CACHE_MIDDLEWARE_KEY_PREFIX
but it doesn't. Because of this if categories module is used when the same django instance has more then one site. The sites share the same category_detail page. I think if this has to be here. There should be a settings field called
KEY_PREFIX_SETTING or something. that we can set in settings so then you would do
@cache_page(CACHE_VIEW_LENGTH, key_prefix=KEY_PREFIX_SETTING)
Otherwise just remove it and let us take care of caching in middle ware.
I also just tried to set the
CACHE_VIEW_LENGTH in settings to
0 - this is the same as no cache. So this doesn't help because we need middleware cache to work
None - This just makes it default to 300 seconds. With the key-prefix as None so this also doesn't help.
Sorry I should have clarified. For django version 1.2.5 it doesn't cause a problem because it defaults key_prefix to CACHE_MIDDLEWARE_KEY_PREFIX. But for communities.washingtontimes it does because 1.3.1 doesn't default the key prefix. Not sure about later versions then 1.3.1
thanks
It looks like you decided to make github the home for the project, but the description still points to http://opensource.washingtontimes.com/projects/django-categories/ ...which no long works.

I have a Coupon model which you can see here:
https://gist.github.com/821401
but when i try and import that model in my main urls.py to make a query set for a generic view i get a "AlreadyRegistered at /" error.
Here is the traceback:
https://gist.github.com/821398
The TreeEditor is currently not functional in Django 1.5 because it's templates use the removed adminmedia tag library. This bug report says it all: feincms/feincms#371
As per: https://docs.djangoproject.com/en/dev/releases/1.5-beta-1/
The template tags library adminmedia, which only contained the deprecated
template tag {% admin_media_prefix %}, was removed. Attempting to load
it with {% load adminmedia %} will fail. If your templates still contain
that line you must remove it.
When I run tests within my django project django-categories throws an ImportError. If I change

ImportError is not thrown.

I'm developing against Django 1.5 beta, and always got an error when installing. After a bit of fiddling, I know that installing django-categories in a clean (--no-site-packages) virtualenv
a) together with Django 1.4.3 works fine (pip install Django django-categories)
b) after having installed Django 1.4.3 works fine (pip install Django && pip install django-categories)
c) together with Django 1.5b2 works fine (surprisingly!) (pip install https://www.djangoproject.com/download/1.5b2/tarball/ django-categories)
d) after having installed Django 1.5b2 fails (pip install https://www.djangoproject.com/download/1.5b2/tarball/ && pip install django-categories)
The log is here: https://gist.github.com/560478e396afa1a289b1
I presume the error has to do with trying to import django.db.models.Q without having settings setup.
If a registered model's admin uses field sets instead of fields, the fields are not added.
Either i am unable to make the tree editor work properly or it is missing some features. All I get i the admin is the arrows.
> Top > Belolw > More > Stuff
I would expect:
> Top magnifyinglass / plus sign / drag handle > Belolw magnifyinglass / plus sign / drag handle > More magnifyinglass / plus sign / drag handle > Stuff magnifyinglass / plus sign / drag handle
Am I missing something or should i use feincms for the admin?
the javascript error happens when you click on the check box on admin tree view. both on opera and firefox the console says
event is not defined: this.checked = event.currentTarget.checked;
and referers to line 48 of the page, which is line 11 of the tree_editor.html template
When a user is logger in to the admin who doesn't have persmission to add categories, the '+' icon/link next to category fields in other apps shouldn't be visible as they only go through the a 'permission denied' page. Not the end of the world, but would be neater if they didn't show.
However, only jQuery 1.3.X is included
Hi,
I'm receiving this error when trying to deactivate a catagory:
Django Version: 1.3.1
Exception Type: AttributeError
Exception Value:
'CategoryAdmin' object has no attribute '_meta'
Exception Location: /home/nuno/Proyectos/hella/src/libs/django-categories/categories/base.py in deactivate, line 132
The code which raise the exception is :
def deactivate(self, request, queryset):
"""
Set active to False for selected items
"""
--> opts = self._meta <-
selected_cats = opts.model.objects.filter(
pk__in=[int(x) for x in request.POST.getlist('_selected_action')])
I'm using this library by directy linking my model with the base Category..as in this case i need some king of "category flat pages"
category = models.OneToOneField('categories.Category')
Can anybody tell me if 'im doing something wrong?
Should I extends CatagoryBase and create a custom "Mycategory" model to use ths library?
Everything is working fine except this.
Thanks in advance

I'm pretty much at a loss here. Why is the add_category_fields command incorrect? Am I missing something that would be obvious to a real Pythonista or Djangonaut?
I simply downloaded the repository, and did a did a mange.py syncdb on the example project. Then when I ran it in the server, when to admin and clicked Categories I got a type error.

EDIT:
I tried running the app through django 1.3.1 and it worked fine. Looks like something changed in Django 1.4 and broke the app.

I am getting the mentioned error when i try to register the model to my app. I dont know what am i doing wrong, but i can't find any info anywhere. i tried to follow the example code, but am lost.
Any ideas?
Thanks.
The register_m2m() function is hard coded to use the Category class.
Is there any other way to do this?

What about translations - are there any planned? Could I start adding a German one? (using ugettext of course)
Now i can count items only with one category, as this
Electronic (0)_first cat -> Computers (13) -> Mainboards (4)_last cat
i want count right items as this
Electronic (17)_first cat -> Computers (17) -> Mainboards (4)_last cat
how to?
get_latest_objects_by_category is documented as if it is a templatetag, but it isn't actually registered as one. Here's a quick and dirty patch to make it work: https://gist.github.com/3021699
I have the following simple model
class Department(CategoryBase):
passjust to build a category tree.
The same model is translated through django-modeltranslate (http://code.google.com/p/django-modeltranslation/), which works on a subscription basis, just like admin.
It automatically adds a field fieldname_ for each language, wrapping the use of fieldname according to the current language.
In my case the field is "name".
When saving an instance django-categories raises an exception, since it tries to create a slug from "name" which is not present in the POST data.
is there a way to solve this incompatibility?
With
implementation of
django.contrib.admin.views.ChangeList.get_ordering expect queryset as second argument, therefore
categories.editor.tree_editor.TreeChangeList.get_ordering should be changed to accept queryset as well.
Admin ChangeList
def get_ordering(self, request, queryset)
Line 15, you use category before declaring it, but I think you meant to use category_string instead.
that's fun, but commenting out function clean_slug(self) is way to solve this problem (i think that slugfield do all the work).
but it makes ALLOW_SLUG_CHANGE useless.
When you use a title that has more than 50 characters a slug is created within the advanced section of the admin panel. Even when you edit this slug to contain less than 50 characters, the application will still give you an error as if there are still too many characters.
perhaps it would be batter naming it categories_editor? it also may help with issue 13.
I'm trying to get django-categories-0.4.8 work with my project (based on django 1.2.1) but no luck so far. One thing I noticed is the models.py file is missing from the editor app. This prevents the staticfiles app from searching into the "editor/media/editor" directory.
Is django-categories-0.4.8 supposed to work with django 1.2.1 by the way?

TypeError: unsupported operand type(s) for -: 'NoneType' and 'NoneType'I've whipped together a few basic class based views to help clean things up in a project I'm working on. I didn't want to do a big full fledged pull request out of the blue, but I figured I'd drop a note to see if anyone is interested.
https://github.com/tgecho/django-categories/tree/classviews
I'm up for whatever fixes/changes. I'll be poking at it a bit more as my project moves along. Also, I'll be needing date based versions soon, so those will be coming along.
CategoryDetailView replicates category_detail, but it's a bit nicer to override pieces (in my case I just wanted to play with the context).
Usage example:
url(r'^categories/(?P.+)/$', CustomCategoryDetailView.as_view(), name='categories_category'),
CategoryRelatedDetail is for showing an object from another model that is partially identified based on the category it belongs to (i.e. using unique_together). As a bonus it creates a nice template cascade for you.
Usage example:
url(r'^categories/(?P<category_path>.+)/photos/(?P.*)/$', CategoryRelatedDetail.as_view(model=Photo), name='photo_detail'),
CategoryRelatedList shows a list of objects of a given model that are related to a category.
Usage example:
url(r'^categories/(?P<category_path>.+)/photos/$', CategoryRelatedList.as_view(model=Photo), name='photo_list'),
Not sure if this is a versions problem. I get this error when loading admin page for Categories:
TypeError: Result of expression '$' [undefined] is not an object.
On this line in treeTable.js
$.fn.treeTable = function(opts) {

The TreeTable collapses all children by default. adding:
var srchString = document.getElementById('searchbar').value;
if (srchString == '')
treeTable = $("#result_list").treeTable({initialState : "{{ EDITOR_TREE_INITIAL_STATE }}"});
else:
treeTable = $("#result_list").treeTable({initialState : "expanded"});
to tree_editor.html will work, but the formatting isn't correct.
I might be wrong but it looks like the template tags only work if your model is called Category.
in import_categories.py,
level is count by:
level = line.count(indent)
this is sometimes wrong because it also counts the non-leading indent chars...
The musicgenres.json fixture fails to load on systems running MySQL + InnoDB — foreign key constraints fail because of the order of the items in that fixture file. Reordering them fixes the problem.
See https://gist.github.com/1373942 for a reordered version of the fixture.
Sorry for such a simple question, but can you tell me the best way to query on objects that either have a parent category of 'News' or have the category name of 'News'? I am currently using Q and the following code:
entries = SuperPage.objects.filter(Q(category__parent__name='News')|Q(category__name='News'))
I have also tried using a superpage_set query with a Category object, but I can't see a way to get all objects for the Parent and all children. Sorry if this makes no sense. I appreciate any help you can give.
An examples showing how to populate something like JSTree from the category data would be useful.
