How to see Django admin panel elements reordered in another tabs?
I want to reorder my django models in admin panel. I found the django-modeladmin-reorder package and installed it. I did everything according to the documentation, but I still have a problem. Reordering elements are being shown only on the main page of the website, if I click on a model to add or edit I see the old reorder. How can I see the new reorders in other tabs ? Good order: https://i.imgur.com/69N1CRs.png Bad order: https://i.imgur.com/9UYLXbX.png This is the code in settings.py ADMIN_REORDER = ( # First group {'app': 'website', 'label': 'Postări', 'models': ('website.Article', 'website.Research', 'website.Reports', 'website.Advocacy', 'website.Document', 'website.Domain', 'website.News', ) }, # Second group: same app, but different label {'app': 'website', 'label': 'Categorii', 'models': ('website.ArticleTag', 'website.ResearchTag', 'website.ReportsTag', 'website.AdvocacyTag', 'website.DocumentTag', 'website.DomainTag', 'website.NewsTag', ) }, {'app': 'website', 'label': 'Video', 'models': ('website.Video', 'website.MainVideo', ) }, {'app': 'website', 'label': 'Rapoarte', 'models': ('website.Reports', ) }, ) -
Django rest_framework DefaultRouter() class vs normal url
I'm using REST in Django, And I couldn't understand what is the main difference between classic URL and instantiating DefaultRouter() for registering URL by ViewSet.

Django AWS tutorial working for tutorial but not for full project
I'm following this tutorial: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html I follow the tutorial exactly, except use Django 4.0.3 and Python 3.8. It works for deploying a sample project, but when I make the settings.py exactly the same and try to put up my full project, I get the follow errors: health degraded 502 Bad Gateway nginx/1.20.0 failed (111: Connection refused) while connecting to upstream I tried to add gunicorn too but nothing was changing.

How to add logic to a model getter that uses inheritance?
I have a model for a Task class Task(BaseTask): class Meta: db_table = 'task' verbose_name_plural = 'Tasks' def __str__(self): return f'Task {self.id}' def __unicode__(self): return f'Task {self.id}' that is inherited from BaseTask class BaseTask(BaseModel): class Meta: abstract = True task_status = models.CharField( choices=TASK_STATUS_CHOICES, blank=True, max_length=200, default=WAITING ) expiration_date = models.DateTimeField(blank=True, null=True, default=None) I want the task_status for Task to return FAILED if the current date is past the expiration date. I thought I could add a getter to Task like: def get_task_status(self): return FAILED if self.expiration_date and \ check_task_is_expired(self) else self.task_status but that doesn't seem to be working. How can I accomplish adding logic to task_status so it returns FAILED after the expiration date? I'm aware of @property but other models depend on BaseTask and Task so I don't want to change the field name. -

python3 manage.py migrate gives error about field even when it is deleted from the model class
Every time I run python3 manage.py migrate I get the same error about one of the fields in the model class. Even after deleting the field, the same error occurs. This is what the model class looks like: class Events(models.Model): name = models.CharField(max_length=200, null=True) date = models.DateTimeField(editable=True, null=True) sport = models.CharField(max_length=200, null=True) location = models.CharField(max_length=200, null=True) description = models.CharField(max_length=200, null=True, blank=True) date_created = models.DateTimeField(auto_now_add=True) tags = models.ManyToManyField(Tag) num_seats = models.IntegerField(null=True, blank=True) creator = models.CharField(max_length=200, null=False) And this is what the error looks like: TypeError: int() argument must be a string, a bytes-like object or a real number, not 'IntegerField' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/Users/laithtahboub/Desktop/Programming/Django/events_project/manage.py", line 22, in <module> main() File "/Users/laithtahboub/Desktop/Programming/Django/events_project/manage.py", line 18, in main execute_from_command_line(sys.argv) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/__init__.py", line 425, in execute_from_command_line utility.execute() File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/__init__.py", line 419, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/base.py", line 373, in run_from_argv self.execute(*args, **cmd_options) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/base.py", line 417, in execute output = self.handle(*args, **options) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/base.py", line 90, in wrapped res = handle_func(*args, **kwargs) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/commands/migrate.py", line 253, in handle post_migrate_state = executor.migrate( File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/db/migrations/executor.py", line 126, in migrate state = self._migrate_all_forwards(state, plan, full_plan, fake=fake, fake_initial=fake_initial) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/db/migrations/executor.py", line 156, in _migrate_all_forwards state … -
Django Query many to many field count miscalculation
I am creating a Django Blog Website and I am stuck at one point finding the no of likes on a specific post. I have created a webpage where all the posts are displayed. Now the problem I am facing is the no of likes are getting calculated wrong. Post Model -> class Post(models.Model): user = models.ForeignKey(User, on_delete=models.PROTECT) title = models.CharField(max_length=255) description = models.CharField(max_length=1000,null=True) Tags = models.CharField(max_length = 255,null=True,blank=True) Created_date = models.DateTimeField(auto_now_add=True) Updated_date = models.DateTimeField(auto_now=True) category = models.ForeignKey(Category, on_delete=models.PROTECT) Likes = models.ManyToManyField(to=User, related_name='Post_likes') favourites = models.ManyToManyField(to=User,blank=True,related_name="favourite") def __str__(self): return self.title Query in Views.py file to fetch all the posts -> posts = Post.objects.select_related().prefetch_related('images_set').annotate(Count('comments_post')).annotate(Count('Likes')).all() Now when I see the post.Likes__count in template it shows wrong count of 6 for one specific post but when I use post.likes.count() it shows count of 3. for other posts they both show same result. I am unable to find out why it is happening. This is the result for that specific post -> {'post_id': 22, 'user_id': 1, 'title': 'wkjdfh', 'description': 'kjwdfn', 'Tags': '.,smdf,m', 'category': <Category: Shoes>, 'userName': 'admin', 'images': <QuerySet [<Images: Images object (10)>, <Images: Images object (11)>, <Images: Images object (12)>, <Images: Images object (13)>]>, 'comments_count': 6, 'likesCount': 6, 'actualLikeCount': 3} This is very … -
How to safely execute user-written code in the backend?
I'm trying to build a Django web application that allows users to write Python code and runs that in the backend, kinda like how an IDE would work. I'm just wondering, what security risks does this come with? I'm sure there are plenty, the user could literally do anything with that code, so what would be a good solution to safely do this? Would running it inside a Docker container be a good solution?
