QUESTION
I am trying to get custom templates working for djangocms-video.
So far there is a fresh djangocms project set up with some bootstrap and running fine.
According to the readme we would need to specify this in the settings.py to make a custom template available (in this case a template named "feature"):
...ANSWER
Answered 2022-Jan-04 at 21:10In Django, the gettext_lazy(…) function [Django-doc] is often imported as _ to manage translations. This is explained in the Standard translation:
Python’s standard library
gettextmodule installs_()into the global namespace, as an alias forgettext(). In Django, we have chosen not to follow this practice, for a couple of reasons(…)
Because of how xgettext (used by makemessages) works, only functions that take a single string argument can be imported as
_:
You thus should add:
QUESTION
Im trying to add the created list page as the first child of the parent Index page. The problem is that when I use django treebeard api django treebeard api it succeeds sometimes but other times it shows me an error:
{'path': ['Page with this Path already exists.']}
How can I solve this?
CODE:
...ANSWER
Answered 2021-Sep-27 at 15:27TreeBeard API Solution: you just need to changethe target node by a sibling or child of a parent node, not the parent node itself.
Pythonic Solution: You Can swap the page ID (Primary Key), first, create your page, then create a function to check all IDs and indicate your newly created page ID, then change the lowest ID number to be equal to the last child(which is your newly created page) + 1 and then change your page ID to the 1 or 0..!
NOTE: if you need to rearrange the entire pages, you better use --fix-tree management command in the terminal(like: python manage.py fixtree), and then go for steps mentioned above, you can also create a recursion function to do all the above at once..! I'll intentionally leave the chance for other developers to help you with recursion functions example(unless you can do it by yourself)..!
QUESTION
Asked another question yesterday. Unfortunately, the answer did not solve the problem so I thought I narrow the question down and ask again.
I have a Category model which is hierarchial(using django-treebeard). When I run example_category.get_descendants() the result I get is a MP_NodeQuerySet like the following
ANSWER
Answered 2021-Aug-27 at 11:21Even if it worked, that query would return a queryset of Category instances.
To get products that have one of the categories from get_descendants you can do

QUESTION
I currently installed django-cms and djangocms-blog. When I run migrate, it throws the following error. Some ressources suggest to install six, which however is already satisfied in my venv.
I use the latest Python, pip and django versions.
These are the guides I followed to set up djangocms and djangocms-blog.
Any solution to this?

Answered 2020-May-09 at 16:36python_2_unicode_compatible was removed from Django in 3.0: https://docs.djangoproject.com/en/3.0/releases/3.0/#removed-private-python-2-compatibility-apis
It looks like you need to update one of your packages that's using it. From the traceback, that would be aldryn_apphooks_config. I'm not sure where that comes from, would need some more details for that. I would suggest checking your requirements file and trying to upgrade packages until it works, but you might have to end up removing some.
QUESTION
I have developed a simple project with DjangoCMS(3.7.2) and it works great in the local. I 'm gonna run it on a ubuntu server, which I have another Django project run on it with no issues. Both of my projects are built using python 3.6 & MySQL database. I took these steps to run my new project:
- Cloned the project from the server via git and updated the
settings.pyfile - Created an empty database on the server
- Installed a virtualenv on server by
python3 -m venv venv - Activated the
venvand upgradedpip - Installed requirements successfully using
pip install -r requirements.txt - Tried to Migrate by
python3 manage.py migrate
But I got this error:

Answered 2020-May-01 at 06:06As Alasdair mentioned:
I reinstalled the Django-CMS module by running python3 -m pip install "django-cms==3.7.2", and surprisingly it worked.
QUESTION
I had a working DjangoCMS application running DjangoCMS 3.7.1 and Django 2.2, however after I just bumped the DjangoCMS version to 3.7.2 and with it, Django to 3.0.1, I am now getting a render error on a page that I have a simple list view.
The site will load my custom account login page just fine, but once logged in, the listview breaks and displays this error: Traceback
...ANSWER
Answered 2020-Apr-27 at 13:38I ran into the same issue upgrading DjangoCMS to 3.7.2. I believe the context argument was removed in Django 3 (source). The problem for me was djangocms-text-ckeditor doesn't support Django 3 yet. More specifically, HTMLField in my model didn't work. I opened an issue here if you want to comment on it as others have done. Maybe it will get them to fix it sooner. For now, you will probably have to wait till it's fixed. Cheers!

You can use django-treebeard like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
