How to get a parameter from a form and insert it in the url with django?
I am a beginner with django. I want to get a parameter that the user has to enter from a form.

How to display searched item for users, but all items only for admins?
There is a page where the list of elements is displayed. Also, there is a search to display elements that have the requested value. I have an account and access control, some elements of the site are visible to everyone, and some only through the account. The problem is that I need to remove the display of the entire list of elements for the guest, but leave the display of the element based on the search results.

How to set ManToManyField to None?
I have a Section model for storing different sections of laws. A law has Part, Book, Chapter, Title, Section, SubSection, ... and Article Instead of making models for each of the above parts, I created a section model to store the sections in the database. The level field in the section model specifies the depth of levels. as you can see in the picture. class Section(Timestamped): parent = models.ManyToManyField( to='self', verbose_name=_("Parent Section"), help_text=_("Specifies the links to another section."), blank=True, symmetrical=False ) level = models.PositiveIntegerField( verbose_name=_("Level of the section"), ) ... My problem is that when I store the first section or level, the parent should be set to null(which means that the first section has no parent). But I get an error when I set the parent to None. I have all the sections in a JSON file: The script for section in sections: section_data = { "text_id": section.get("id"), "level": 1, } section_db, created = Section.objects.get_or_create(**section_data) section_db.parent.add(None) The error django.db.utils.IntegrityError: null value in column "to_section_id" of relation "laws_section_parent" violates not-null constraint DETAIL: Failing row contains (3, 22, null). Is there any solution? Are the models correctly designed? -

Django UniqueConstraint not working as expected
At the moment I am using the following condition to avoid duplicates MyModel.objects.filter(other_model=self, ended__isnull=True, started__isnull=False).exists() which works, however due to unfortunate caching etc. in the past there were duplicate instances of this. I want to move this exact check to the database level with Django. I tried different constraints using a simple unique_together ([['other_model', 'ended']]) constraint and constraints = [ models.UniqueConstraint(fields=['other_model', 'ended'], name='unique_name', condition=models.Q(ended__isnull=True)) ] This is my testcase, which runs without a problem (which it shouldn't) ts = timezone.now() MyModel.objects.create(other_model=same_instance, ended=ts, started=ts) MyModel.objects.create(other_model=same_instance, ended=ts, started=ts) This is the latest migration (I even reset the entire DB and reapplied all migrations): migrations.AlterUniqueTogether( name='mymodel', unique_together={('other_model', 'ended')}, ), -

Why does nginx not redirect to https?
I'm trying to deploy my Django application but I'm having issues with the redirect to https added in my nginx config by Certbot. This is what my config looks like: server { server_name somedomain.com; location /static/ { root /var/www/somedomain; } location / { include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } listen 443 ssl; # managed by Certbot ssl_certificate /etc/letsencrypt/live/somedomain.com/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/somedomain.com/privkey.pem; # managed by Certbot include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot } server { if ($host = somedomain.com) { return 301 https://$host$request_uri; } # managed by Certbot listen 80; server_name somedomain.com; return 404; # managed by Certbot } With https the site works fine, but for http there is no response: curl http://somedomain.com curl: (28) Failed to connect to somedomain.com port 80 after 78173 ms: Operation timed out
