Django google kubernetes client not running exe inside the job
I have a docker image that I want to run inside my django code. Inside that image there is an executable that I have written using c++ that writes it's output to google cloud storage. Normally when I run the django code like this: container = client.V1Container(name=container_name, command=["//usr//bin//sleep"], args=["3600"], image=container_image, env=env_list, security_context=security) And manually go inside the container to run this: gcloud container clusters get-credentials my-cluster --region us-central1 --project proj_name && kubectl exec pod-id -c jobcontainer -- xvfb-run -a "path/to/exe" It works as intended and gives off the output to cloud storage. (I need to use a virtual monitor so I'm using xvfb first). However I must call this through django like this: container = client.V1Container(name=container_name, command=["xvfb-run"], args=["-a","\"path/to/exe\""], image=container_image, env=env_list, security_context=security) But when I do this, the job gets created but never finishes and does not give off an output to the storage. When I go inside my container to run ps aux I get this output: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 2888 1836 ?

Django: Errors when switching DateTimeField into DateField
I'm working on a project with Django. I used DateTimeField() when I first created some Model. I also created hundreds of instances. Then I decided that DateField was more appropriate and changed it. when I migrate, It was migrated well without any warning messages. But when I try to access original instances made with DateTimeField, I received the following error. invalid literal for int() with base 10: b'13 00:00:00' The Error seems to have occured because datetimefield data remains even though format has changed. But I don't know how to resolve it since I get this errors even when I try to delete existing instances. I also wonder why this error appears. -

Custom actions in nested Django model
I currently have a model Thing that has User model as foreign key: class Thing(models.Model): user = models.ForeignKey(User, on_delete=models.PROTECT) If I use Thing as standalone in admin, I can override deletion as follows: class ThingAdmin(admin.ModelAdmin): actions = ['delete_model'] def delete_model(self, request, obj): for o in obj.all(): # Do stuff o.delete() This works: if I go into admin, I click on 'Things', select which ones I wish to delete and the custom part runs (I wish there was a way to create a button instead of using a dropdown, but this is good enough). I do not, however, wish to have things as standalone in admin. I want them in a nested view from User model so that I could delete them directly from user view. For that reason, I use django-nested-admin: class ThingInline(nested_admin.NestedStackedInline): actions = ['delete_model'] def delete_model(self, request, obj): for o in obj.all(): # Do stuff o.delete() The things are displayed fine, but I am not getting a 'delete model' button anywhere. Question: how do i created custom actions for nested models? -
django-storages (azure) - accessing data without defining my azure container as the default file storage
So I have my azure storage which looks like this: class PublicAzureStorage(AzureStorage): account_name = 'myaccount' account_key = 'mykey' azure_container = 'mypublic_container' expiration_secs = None I want to get all the files that this container has and display them in my app - but my default file storage & static file storage are still local. From Azure I only want to get some .CSVs. How can I access this container as I said? In the docs it seems that I need to set Azure as the DEFAULT_FILE_STORAGE/STATICFILES_STORAGE in order to work. -

Encrypt message field in django & render it on React after decrypting

Adding a tag to a pagination element django
When creating a pagination, everything works as it should. Added (?page= page number selection) pagination. How can I add the pagination page number to its object? When selecting an object and reloading the page, I need it to be spelled out in the URL (/?page=pagination number). And the pagination remained on the selected page. class MovieShow(DetailView): model = Movie template_name = 'movies/movie_play.html' context_object_name = 'movie' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['object_list'] = Movie.objects.filter(course__slug=self.kwargs['course_slug']) context['title'] = context['movie'] paginator = Paginator(context['object_list'], 1) page = self.request.GET.get('page') try: context['object_list'] = paginator.page(page) except PageNotAnInteger: context['object_list'] = paginator.page(1) except EmptyPage: context['object_list'] = paginator.page(paginator.num_pages) return context This is how I present pagination in the template <div class="pagination" id="pagination"> <span class="step-links" > {% if object_list.has_previous %} <a class="page-link" href="?page=1"> << </a> <a class="page-link" href="?page={{ object_list.previous_page_number }}"> < </a> {% endif %} <span class="current"> {{ object_list.number }} из {{ object_list.paginator.num_pages }} </span> {% if object_list.has_next %} <a class="page-link" href="?page={{ object_list.next_page_number }}"> > </a> <a class="page-link" href="?page={{ object_list.paginator.num_pages }}"> >> </a> {% endif %} </span> And so I have a search of the elements inside the pagination, on which I want to hang the pagination page number.

Fetch files from outside of SvelteKit project directory
I'm fetching data, including media file links, from a Django API.

The media link I'm receiving by my API would be something like this: /media/images/user1/image.jpg Thanks in advance!
