Celery wont run when initiated by supervisor on aws elasticbeanstalk
I am attempting to daemonize celery beat and worker. I have no troubles running celery or beat when I ssh into my Elastic Beanstalk instance and do the following steps: cd /opt/python/current/app /opt/python/run/venv/bin/celery -A myDjangoApp beat --loglevel=INFO /opt/python/run/venv/bin/celery -A myDjangoApp beat --loglevel=INFO Tasks are scheduled and able to execute with ease. However when I run the exact same commands with supervisor I am getting an uniformative error. From looking at supervisorctl status I see the process runs for a few seconds then fails. Upon further examination the the log files show me the following error: File "/opt/python/run/venv/bin/celery", line 11, in <module> sys.exit(main()) File "/opt/python/run/venv/local/lib/python3.6/site-packages/celery/__main__.py", line 15, in main sys.exit(_main()) File "/opt/python/run/venv/local/lib/python3.6/site-packages/celery/bin/celery.py", line 213, in main return celery(auto_envvar_prefix="CELERY") File "/opt/python/run/venv/local/lib/python3.6/site-packages/click/core.py", line 829, in __call__ return self.main(*args, **kwargs) File "/opt/python/run/venv/local/lib/python3.6/site-packages/click/core.py", line 760, in main _verify_python3_env() File "/opt/python/run/venv/local/lib/python3.6/site-packages/click/_unicodefun.py", line 130, in _verify_python3_env " mitigation steps.{}".format(extra) RuntimeError: Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment.

Django admin problem with changed table column's name
I'm new to Django. Everything was fine before, but now that I've changed the name of some columns in the table, when I want to check all data inside the admin panel, It returns error. It seems that the admin still expect the previous column's names. And also the name of the models has an extra "s" at the end! For example, one of the previous column's name was "note_text" which I've changed to "text". So, what should I do now? -
Aggregating change list rows in Django using values
I'm trying to modify my model's changelist so that the user can select different filters which will sum specific fields in the model, grouping by different time frames (week, month, year). I have created a custom SimpleListFilter which correctly performs the aggregation. The problem is that it uses the values method which returns dict objects instead of my model, causing various errors. My model: class UsageReport(models.Model): install = models.ForeignKey( Installation, on_delete=models.CASCADE, help_text='The install this report is associated with' ) date = models.DateField( null=False, blank=False, default=None, help_text='The day this report\'s data is compiled for' ) players_count = models.PositiveIntegerField( null=False, blank=False, default=0, help_text='The number of new players created' ) captures_count = models.PositiveIntegerField( null=False, blank=False, default=0, help_text='The number of new captures created' ) created_at = models.DateTimeField(auto_now_add=True, null=True) My custom list filter: class DateGroupFilter(SimpleListFilter): title = 'Group By' parameter_name = 'group_by_date' def lookups(self, request, model_admin): return ( ('week', 'Week'), ('month', 'Month'), ('year', 'Year') ) def queryset(self, request, queryset): if self.value() == 'week': return queryset.annotate(week=ExtractWeek('date')).values('install', 'week').annotate( sum_players=Sum('players_count')).annotate(sum_captures=Sum('captures_count')) if self.value() == 'month': return queryset.annotate(month=ExtractMonth('date')).values('install', 'month').annotate( sum_players=Sum('players_count')).annotate(sum_captures=Sum('captures_count')) if self.value() == 'year': return queryset.annotate(year=ExtractYear('date')).values('install', 'year').annotate( sum_players=Sum('players_count')).annotate(sum_captures=Sum('captures_count')) Since each filter option returns slightly different fields (week, month, year) I tried to code a work-around which overrides the get_list_display method … -

Queryset en Django
soy nuevo en Django y quería saber si hay alguna forma de hacer filtrados de querys con multiples valores de un mismo campo de mi modelo? Follow es mi modelo donde guardo los pk de los usuarios follower y following; la consulta follows me devuelve todos los follows en los que yo figuro como follower para después poder acceder al atributo following. Después hago un lista de los pk de following para filtrar los posts hechos por usuarios con los pk de mi lista de following. Sé que entregar un lista como parametro da error, pero la plasmo para intentar explicar lo que quiero hacer que es filtrar todos los post de los usuarios que sigo. Dejo la vista que lista los posts: class PostsFeedView(LoginRequiredMixin, ListView): """Return all posts published by following.""" template_name = "posts/feed.html" ordering = ("-created") paginate_by = 30 context_object_name = "posts" def get_queryset(self): user = self.request.user follows = Follow.objects.filter(follower=user.pk) following = [] for follow in follows: following.append(follow.following) posts = Post.objects.filter(user__id=following) return posts -
How to create a product filter, when products are just foreigns keys in attribute class? (Django Ecommerce)
I'm trying to create a product filter that filters on product attributes (like this example), but I have a couple of issues: The attributes of my products are defined indirectly as a foreign key in a ProductAttributesValue class, which connects a product and an attribute key to an attribute value, i.e.: class ProductAttributesValue(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) attribute = models.ForeignKey(ProductAttributes, on_delete=models.RESTRICT) value = models.CharField( verbose_name = "value", max_length = 255 ) For now, I simply show all associated products on each product category page. Meaning attributes aren't used, yet. How do I, on the product category pages, create a filter on the product attributes, when they aren't directly defined in the Product class as a model field? Is this even the optimal way of setting up product attributes? (Categories are set up using MPTT, and I found this attribute implementation through online guides). An important note is that I want product filtering to be "hard URLs", meaning /red/ instead of ?color=red. This one requires some sort of hierarchy in the filtering, as there must be no duplicate URLs (e.g: /red/hugo-boss and /hugo-boss/red). Thanks! -

Recommendations for an AutoComplete library for Django Taggit
Aside of another post I created earlier this evening relating to the configuation of Django AutoComplete Light, I just wanted to ask - What are the most recommended AutoComplete libraries out there which work with the latest version of Django? A lot of the libraries I have come across seem to be no longer maintained or are 6+ years old. I am tempted currently to continue with implementing Django AutoComplete Light although, I thought I would check here first to see if there are any other alternatives which exist? If anyone could provide me with any tips with which is the most favourable library (which works with the latest version of Django, that would be great!) Ideally, I am wanting the Select2 and tag bubbles similar to the Tagulous AutoComplete library. All suggestions are welcome. Thanks! -

Не отображаются поля формы django в модальном окне bootstrap

How to split a long line in a Django template needed for formatting?
I have a line like this in a Django template: {{ some_prefix }}{% if obj.obj_type == A_LONG_CONSTANT %}1{% elif obj.obj_type == A_LONG_CONSTANT %}2{% endif %}{{some_suffix}}: where some_prefix might be a ( or something longer, and some_suffix might be a ) or maybe even empty. I don't know how to break this up, since putting any whitespace in such a template make it look different in a browser. Think "( hi )" instead of "(hi)". Any suggestions? You might say, "Put this in python, not Django templates." However, I'm not sure how to split it up into a tag either. It depends on the template context. I see this question, but that's just renaming variable names, which might make this thing even more heinous. I think there's probably nothing to do. -
Strange Error with Django oauth-toolkit and Azure App Service. Returns 401 {"detail":"Error decoding token."} when attempting to authenticate token
Hi I am deploying an app to Azure App Service using Django Rest Framework with OAuth2 authentication handled by django-oauth-toolkit (https://github.com/jazzband/django-oauth-toolkit). Recently when trying to connect to my React frontend I have found out that I cannot successfully authorize despite having an access token. When I make a the following API call (as suggested by the documentation): curl 'http://exampleurl.azurewebsites.net/endpoint/' -H 'authorization:Bearer <sampletoken>' I get the following response: {"detail":"Error decoding token."} I cannot recreate this error locally nor can I find any information about this error anywhere online. I even searched the repository for the error to see if I could find what triggers it, unfortunately no luck. Has anyone else ever experience this or can give me some insight on what potentially occurred in my deployment to cause this? I also deleted out my old deployment and even app service to completely start from scratch and the problem persisted. -
How to set up Django Machina custom permissions
I am new to Django and python. I have been able to alter a custom user model so that the user signup form presents the user with categories and category subforums populated from Machina tables. An example would be a user choosing the category of "Biology" (category forum) and a subcategory of microbiology (subforum of the category "Biology"). When the users view the main forum page, I only them to see a couple of site wide forums and the category/subforum they chose upon registration. I am not sure how to customize Machina to accomplish this. I found the forum permissions handler.py here: https://github.com/ellmetha/django-machina/blob/a92041c2854bee6b80d418fabd4cec5caac91dc3/machina/apps/forum_permission/handler.py#L300 It seems to offer some possible ways to accomplish what I want to do, but I am not sure of a good approach.

Is it safe to call emit_post_migrate_signal from within a Django migration?
Background My original issue that lead me to this was my desire to create a Group within a django migration (not a problem) and then also assign permissions to that Group within a migration (problem arises here). It seems that in Django that ContentTypes and Permissions are created post-migration. So migrations cannot assign Permissions to Groups because the Permissions don't exist yet. ContentType and Permission generation is triggered by the post_migrate signal, which appears to be sent automatically after all migrations have been applied. There is this work around, in which you manually call emit_post_migrate_signal from within your migration. This will generate all ContentTypes and Permissions, and then the migration can indeed successfully apply them to the Group. Question My question is: is this actually safe to do? I can't find any documentation on the emit_post_migrate_signal function, and emitting a post_migrate signal in the middle of a migration seems like a recipe for something to go wrong (either now or in the future). -

I use Apache like a proxy to send the request to Daphne : <VirtualHost *:443> AllowEncodedSlashes On ServerName mysite.com ServerAdmin admin@gmail.com ProxyPass "/" "http://127.0.0.1:8001/" ProxyPassReverse "/" "http://127.0.0.1:8001/" Header set Access-Control-Allow-Origin "*" Header set Access-Control-Allow-Methods "GET" env=CORS Header set Access-Control-Allow-Credentials "false" env=CORS SSLCertificateFile /etc/letsencrypt/live/****/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/***/privkey.pem Include /etc/letsencrypt/options-ssl-apache.conf </VirtualHost> I launch Daphne with the command : daphne -p 8001 asgi:application When I access to my website, the log of Daphne are : 2021-06-04 21:17:17,821 INFO Adding job tentatively -- it will be properly scheduled when the scheduler starts 2021-06-04 21:17:17,865 INFO Added job "my_job" to job store "default" 2021-06-04 21:17:17,866 INFO Scheduler started 2021-06-04 21:17:17,909 INFO Starting server at tcp:port=8001:interface=127.0.0.1 2021-06-04 21:17:17,912 INFO HTTP/2 support not enabled (install the http2 and tls Twisted extras) 2021-06-04 21:17:17,913 INFO Configuring endpoint tcp:port=8001:interface=127.0.0.1 2021-06-04 21:17:17,919 INFO Listening on TCP address 127.0.0.1:8001 2021-06-04 21:17:20,053 INFO Running job "my_job (trigger: cron[second='*/20'], next run at: 2021-06-04 21:17:20 CEST)" (scheduled at 2021-06-04 21:17:20+02:00) 2021-06-04 21:17:20,054 INFO Job "my_job (trigger: cron[second='*/20'], next run at: 2021-06-04 21:17:20 CEST)" executed successfully 2021-06-04 21:17:40,105 INFO Running job "my_job (trigger: cron[second='*/20'], next run at: 2021-06-04 21:17:40 CEST)" (scheduled at 2021-06-04 21:17:40+02:00) … -
Models Mixin ManytoMany
I want to implement in django a model mixin. I have in mixin.py: class RightsModelRelation(models.Model): user_link = models.ForeignKey(User, on_delete=models.CASCADE, blank=False, null=False, default=None, related_name="%(class)s_rights_user") right_to_view = models.BooleanField(default=True) right_to_change = models.BooleanField(default=False) right_to_delete = models.BooleanField(default=False) class RightsModelMixin(models.Model): rights_link = models.ManyToManyField(RightsModelRelation, default=None, related_name="%(class)s_rights_link") models.py: class Address( RightsModelMixin,models.Model): lastname = models.CharField(max_length=255, default="", ) firstname = models.CharField(max_length=255, default="", blank=True, null=True) But this don't work. Can anyone help me to implement a manytomany models mixin?
