Using @fontface with DigitalOcean Spaces
I've started learning to use django and have starting working on hosting one on Digital Ocean's App platform. I'm hosting my static files on Digital Ocean's Spaces. My CSS file loads just fine. My fonts, however, do not. My file structure is as folows: Project --Static ---CSS -CSS files ---Fonts - font files I set up my @font-face in the CSS file like this: @font-face { font-family: 'poppins'; src: url('../static/fonts/Poppins-Light.woff2') format('woff2'); } and apply the font as follows: .div-name{ height: 100px; font-family: 'poppins'; font-size: 40px; } Like I said, my CSS loads just fine, the fonts are just not showing up. What am i missing? Thanks for the help. -

Why is my debug Django server takes so long to load on my localhost? I'm using Django, django-compressor, django-libsass and bootstrap
I have a problem with developing a Django website. I started out with using CDN Boostrap and JS as recommended in Boostrap 5 docs but then I wanted to customize the CSS, so I changed the setup to compile Bootstrap's source scss files with django-libsass. I followed the installation guides for django-libsass and django-compressor. What I discovered is that while everything works, it works very slow on my local machine (5-6s per opening a new page). I'm not very experienced in web development so I'm not sure what could be causing this. If it's relevant, I don't use a frontend yet and I'm sticking to Django's templates. I tried to download a sample django libsass project and put bootstrap there and the outcome was the same. I expected the time for loading the pages to increase slightly due to the fact that now it has to compile scss files but not so much. Googling turned up no results:( Is this an expected behavior when debugging from a local machine or am I missing something? Huge thanks! -
Is there a way to implement select all/select none option in django-select2?
I found a few (older) answers where someone attempted to implement a select all/select none option in a jQuery dropdown list: https://github.com/select2/select2/issues/195 Select2 select all dropdown option I was wondering, is there a way to implement such a thing also in django-select2? My JavaScript coding capabilities are unfortunately very limited. Simply replacing select2 with djangoSelect2 or django-select2 in the proposed JavaScript didn't do the trick. It starts with the fact that $.fn.djangoSelect2.amd is undefined. -
Call to Stripe API leads to unexpected user logout from Django session
I have a simple Django view where I issue a call to Stripe API (PaymentMethod.detach), and then I am redirecting to a new page: from django.http import HttpResponse from django.contrib.auth.decorators import login_required from django.shortcuts import redirect import stripe stripe.api_key = "secret" @login_required def view(request, method_id): if request.method == 'POST': stripe.PaymentMethod.detach(method_id) return redirect('new-page') else: template = " ... " context = { ... } return HttpResponse(template.render(context, request)) DEV settings.py: DEBUG = True SESSION_ENGINE = "django.contrib.sessions.backends.db" SESSION_COOKIE_HTTPONLY = True SESSION_COOKIE_SECURE = not DEBUG CSRF_COOKIE_SECURE = not DEBUG The problem is that I recently found out that my user is getting logged out from Django when redirected to the new-page. This happens 100% of the time. I believe this is related to the Stripe call because there is nothing else in that view and also when I comment out the Stripe call, then no logout occurs. I have tried a bunch of different SESSION settings but nothing worked so far. I am currently trying to understand what is triggering the logout in the SESSIONS middleware. Any tips on what the issue might be will be greatly appreciated! python == 3.10.6 django == 4.1.6 stripe == 5.1.1 -
Permission denied (publickey,password) Apache in Ubuntu 20.04LTS
I obtain the above mentioned error "Permission denied (publickey,password)" when trying to connect with ssh using my apache server. The framework I have used is Django and when deploying it locally (with python) the ssh communication works perfectly. However, when I deploy it with apache on every ssh, scp communication I obtain the error. I have changed apache User to other than www-data and I got the same result. Obviously, ssh keys for both users are stored in both machines and they work perfectly without using apache. I dont know if it would be possible for apache to look for ssh keys at any specific folder or how to change the default directoy. Any help is much appreciated! -

How to create right relations between models in Django project

Django : pre-filled forms by database
I created travels (pretty much like products) for my site and I want an admin to chnage some informations about those. So I created a form to change the informations.

How to set userkey_id with @setter and token in django?
I have created a client frontend and have tested the url using cUrl and it works, sending the auth token via axios headers allows me in to call the api.

Celery will continue to execute historical tasks after the worker terminates abnormally and restarts
I added the celery crontab task. When an exception occurs in the worker, I hope that the worker will no longer execute unfinished historical tasks. I used the following task base class and wanted to preprocess the task by judging the status of the worker, but it didn't achieve the result I expected. When I stop the worker, after the time exceeds the task execution time, I restart the worker, it still executes the expired task. class MyTask(Task): def before_start(self, task_id, args, kwargs): inspect = app.control.inspect() active_workers = inspect.active() if not active_workers: print('worker not runing') return False print('worker runing') return super().before_start(task_id, args, kwargs) @app.task(base=MyTask) def test(): return 'test' I hope there is any method or parameter setting that can make the worker no longer execute expired tasks -

Django migrations deployment strategy with AWS ECS Fargate?
What is the recommended deployment strategy for running database migrations with ECS Fargate? I could update the container command to run migrations before starting the gunicorn server. But this can result in concurrent migrations executing at the same time if more than one instance is provisioned. I also have to consider the fact that images are already running. If I figure out how to run migrations before the new images are up and running, I have to consider the fact that the old images are still running on old code and may potentially break or cause strange data-corruption side effects. I was thinking of creating a new ECS::TaskDefinition. Have that run a one-off migration script that runs the migrations. Then the container closes. And I update all of the other TaskDefinitions to have a DependsOn for it, so that they wont start until it finishes. -

However every time I try to start the development server I get this following error: Traceback (most recent call last): File "/home/ubuntu/personalserver/manage.py", line 22, in <module> main() File "/home/ubuntu/personalserver/manage.py", line 18, in main execute_from_command_line(sys.argv) File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/core/management/__init__.py", line 446, in execute_from_command_line utility.execute() File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/core/management/__init__.py", line 440, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/core/management/base.py", line 402, in run_from_argv self.execute(*args, **cmd_options) File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/core/management/base.py", line 448, in execute output = self.handle(*args, **options) File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/core/management/base.py", line 96, in wrapped res = handle_func(*args, **kwargs) File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/core/management/commands/migrate.py", line 114, in handle executor = MigrationExecutor(connection, self.migration_progress_callback) File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/db/migrations/executor.py", line 18, in __init__ self.loader = MigrationLoader(self.connection) File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/db/migrations/loader.py", line 58, in __init__ self.build_graph() File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/db/migrations/loader.py", line 235, in build_graph self.applied_migrations = recorder.applied_migrations() File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/db/migrations/recorder.py", line 81, in applied_migrations if self.has_table(): File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/db/migrations/recorder.py", line 57, in has_table with self.connection.cursor() as cursor: File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/utils/asyncio.py", line 26, in inner return func(*args, **kwargs) File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/db/backends/base/base.py", line 323, in cursor return self._cursor() File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/db/backends/base/base.py", line 299, in _cursor self.ensure_connection() File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/utils/asyncio.py", line 26, in inner return func(*args, **kwargs) File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/db/backends/base/base.py", line 281, in ensure_connection with self.wrap_database_errors: File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/db/utils.py", line 91, in __exit__ raise dj_exc_value.with_traceback(traceback) from exc_value File "/home/ubuntu/personalserver/myprojectenv/lib/python3.10/site-packages/django/db/backends/base/base.py", line 282, … -
Can´t find a way to change the initial value of the primary key id, and make start from it on my models
I really apreciate somebody's help.... I am working on django, so I created my table on my models.py.... by default when I start registering data, the id, set as primary key, begins with the initial value #1 and counting on each time I do a new register. But, I have loaded some data in my table, so the final id right now is 185. I runserver and try to add a new register, but I get an error about id duplicity..... django is trying to save in id # 1 the actual register.... but I want it to continue saving the register from id #186 and counting on... I have tried doing this on my models: class MyModel(models.Model): id = models.AutoField(primary_key=True, initial=123) but it does not recognizes the kwarg 'initial' So I am stuck right now....
