I created a view to get the Anonymous users IP, I want when this user what the video then register this ip has watched the video,I know it's now efficient because might the user use diffrent network, This my model of the user by ip: class UsersByIP(models.Model): ip_user = models.GenericIPAddressField() def __str__(self): return self.ip_user This model to make relationship between the vdeo and the number of viewrs by ip class Video(models.Model): viewers_by_ip = models.ManyToManyField(UsersByIP, default='192.168.0.1', blank=True) I created this view to register the ip as view but I got this error: Field 'id' expected a number but got '127.0.0.1' and I couldn't solv it.

Django is sending error mails to admins but they don't reach Sentry
We have a site in production where Sentry is enabled but strangely some of the errors are not being reported to Sentry but are only being sent as emails to the admins set in the settings. Which logger settings we need to change so that only Sentry is used and no direct emails are sent? Our project is based on the cookiecutter-django code base. This is our current logger settings: General logger settings: LOGGING = { "version": 1, "disable_existing_loggers": False, "formatters": { "verbose": { "format": "%(levelname)s %(asctime)s %(module)s " "%(process)d %(thread)d %(message)s" } }, "handlers": { "console": { "level": "DEBUG", "class": "logging.StreamHandler", "formatter": "verbose", } }, "root": {"level": "INFO", "handlers": ["console"]}, } and the Sentry config: SENTRY_DSN = env("SENTRY_DSN") SENTRY_LOG_LEVEL = env.int("DJANGO_SENTRY_LOG_LEVEL", logging.INFO) sentry_logging = LoggingIntegration( level=SENTRY_LOG_LEVEL, # Capture info and above as breadcrumbs event_level=logging.WARNING, # Send errors as events ) sentry_sdk.init( dsn=SENTRY_DSN, integrations=[sentry_logging, DjangoIntegration(), CeleryIntegration()], ) -
How can I filter questions that are answered/unanswered?
In attempting to replicate the unanswered QuerySet functionality of Stack Overflow, I'm left stuck how this would be done at the table level? How would I go about implementing a QuerySet where it returns all unanswered questions when the Question model doesn't have any foreign key reference to Answer on the table itself? It's only when an individual question has been queried that reverse relationship of answers can be accessed. class QuestionStatusQuerySet(models.QuerySet): def unanswered(self): pass def newest(self): pass class Question(models.Model): title = models.CharField(unique=True, max_length=50) body = models.TextField() dated = models.DateField(default=date.today) likes = models.IntegerField(default=0) user_account = models.ForeignKey( 'users.UserAccount', on_delete=models.SET_NULL, null=True, blank=True, related_name="questions" ) tags = models.ManyToManyField(Tag, related_name='questions') objects = models.Manager() dateranges = DateRangeQuerySet.as_manager() status = QuestionStatusQuerySet.as_manager() class Meta: ordering = ['-dated'] default_manager_name = "objects" def __str__(self): return self.title class Answer(models.Model): question = models.ForeignKey( Question, on_delete=models.CASCADE, related_name="answers" ) response = models.TextField() dated = models.DateField(auto_now_add=True) likes = models.IntegerField(default=0) user_account = models.ForeignKey( 'users.UserAccount', on_delete=models.SET_NULL, null=True, blank=True, related_name="answers" ) class Meta: ordering = ['-likes'] -
Django's 'python manage.py runserver' does not create a local website I can access
I am trying to follow this online class, and I am stuck on the part where I access a local website made by django. The tutorial that I follow is this one by freecodecamp, and I get stuck by the 11min mark where I try to access the output site http://127.0.0.1:8000/ . I am following this tutorial on the browser version of Jupyter Notebook. Tutorial: https://www.freecodecamp.org/news/create-an-e-commerce-site-with-django-and-vue/ The 'python manage.py runserver' line runs, and I get the following output: System check identified no issues (0 silenced).

When I copy and paste the server address into the browser, I just get the following error saying that I wasn't able to connect to the site: Unable to connect Firefox can’t establish a connection to the server at 127.0.0.1:8000. The only resource I really found that addressed this issue was the following post, but when I went through my netstat list, there were no IPs listing :8000, so I don't think that I am using up that address already.

CSS file not reloading on change with nginx-gunicorn-django
Firstly I've tried most of the solutions suggested in Stack and from Google. None of the below solutions work when DEBUG MODE is off. sudo systemctl daemon-reload , sudo systemctl restart gunicorn to make sure its not a gunicorn issue Turned off all caching from nginx. Made sure this was the case with curl -I "https://swjungle.shop/2static/CACHE/css/output.9291a1ea98ad.css" returns Cache-Control: no-cache Checked Nginx config again. If debug=True the static files are still not reloaded until collectstatic. But after collectstatic it works. .staticfiles is my STATIC_ROOT location /2static { alias /home/.staticfiles; } sudo systemctl restart nginx also does not reload caching My browser caching is off and I did a hard reload , Ctrl + F5. Deleted all cookie. None of it works... Struggling to find a solution. -
Django is returning JsonResponse, can see the desired JSON response in browser Network tab, but unable to access on the FE

Django ListView works but DetailView not displaying Model Data
I am helping my daughter with her computing Project for school. It is a simple generic forum type application. She has a ListView for a model which works fine: {% extends 'users/main.html' %} <!-- Here is where our content will begin --> {% block content %} <h1>This is posts.html!</h1> <br/> {% for obj in object_list %} <h2>{{ obj.topic }}</h2> {{ obj.date_posted }} <br/> {{ obj.content }} <br/> Author: {{ obj.author }} <br/><br/> {% endfor %} {% endblock %} She then added a DetailView which is simply the same code with the loop removed: {% extends 'users/main.html' %} <!-- Here is where our content will begin --> {% block content %} <h1>This is posts.html!</h1> <br/> {{ obj.id }} <h2>{{ obj.topic }}</h2> {{ obj.date_posted }} <br/> {{ obj.content }} <br/> Author: {{ obj.author }} <br/><br/> {% endblock %} This is then called with a '....post/1/' (post id = 1 does exist (checked via DB Browser and in the ListView) and the path and naming of the template is correct. Frustratingly, this displays the page but not the details inside the django temp language brackets (object.topic etc)!

django orm filter and exclude by related date field

Django admin inline change fields on new record
Background I'm customizing the admin pages for an inventory system with a lot of ManyToMany relationships and other complex data. I want to display these relationships using Inlines, but I don't like the default drop-down field that Django uses for ManyToMany relationships in an Inline so I customized the field set. My custom fields are relatively simple, an ID field that links to the related record, readonly text fields with data from the related record since the Inline can't get fields from the related record by default; that sort of thing. Problem The issue is that in order to use custom fields in these inlines, I've had to make them all read-only. Normally that's fine, because of the linked ID field, but it's impossible to add a new record via the button on the Inline because I can't enter any of the necessary information. My IDs aren't even auto-incremented since this data needs to sync up with another Database, so the new row doesn't link to a newly created record. Basically, what I want to do is have a different set of writable fields on newly added rows so that required fields, like the ID, can be filled. Issues I've … -

Can't get a combination of if and elif to work in django
I have two variables, date1 and date2, both DateField. Here's what I'm trying to write: if date1 and date2 have values, display "Datation évaluée entre date1 et date2". if date1 have value but not date2, display "Datation évaluée vers date1". if date2 have value but not date1, display "Datation évaluée vers date2". if neither date1 nor date2 have values, don't display anything. Here is my code: {% if 'date1' and 'date2' %} Datation évaluée entre {{ object.date1 }} et {{ object.date2 }}. {% elif not 'date1' %} Datation évaluée vers {{ object.date2 }}. {% elif not 'date2' %} Datation évaluée vers {{ object.date1 }}. {% elif not 'date1' or 'date2' %} Datation inconnue. The first condition appears indeed, but not the others. When there's a value only on one side, I get "Datation évaluée entre value1 et None.", and when there are no values, I get "Datation évaluée entre None et None." Any ideas what's wrong in the code? Thanks for your help.
