nginx, gunicorn & django on amazon lightsail, what is the hostname of the ip address?
I deployed a Django application to Amazon Lightsail VPS, and it works as expected when I access it by the domain name xxxxx.com, However, if I tried to access it by the IP address, it gave an error: Invalid HTTP_HOST header: 'ec2-MY-IP-ADDR-Here.compute-1.amazonaws.com'. You may need to add 'ec2-MY-IP-ADDR-Here.compute-1.amazonaws.com' to ALLOWED_HOSTS. DisallowedHost at / Invalid HTTP_HOST header: 'ec2-MY-IP-ADDR-Here.compute-1.amazonaws.com'. You may need to add 'ec2-MY-IP-ADDR-Here.compute-1.amazonaws.com' to ALLOWED_HOSTS. Request Method: GET Request URL: https://ec2-MY-IP-ADDR-Here.compute-1.amazonaws.com/` Of course, the MY-IP-ADDR-Here is my actual IP address number. I wander: Why did the lightsail change the url from 'MY.IP.Addr.Here' to ec2-MY-IP-ADDR-Here.compute-1.amazonaws.com/? Why did the nginx proxy this request to Django? I expected it to discard the request. Is it safe to add the ec2-MY-IP-ADDR-Here.compute-1.amazonaws.com to my allowed hosts? Is it a good idea to remove MY-IP-ADDR-Here from my'settings.py`? The following are the related configuration parameters: /etc/nginx/sites-enabled/mysite server { listen 80; server_name xxxxx.com MY.IP.ADDr.Here; location / { include proxy_params; proxy_set_header X-Forwarded-Proto $scheme; proxy_redirect off; proxy_pass http://unix:/run/gunicorn.sock; } } # many lines created hy certbot # `# I added the following block to tell nginx to discard any request that doesn't match the xxxxx.com MY.IP.ADDr.Here; # https://docs.djangoproject.com/en/5.0/howto/deployment/checklist/#allowed-hosts` server { listen 80 default_server; listen [::]:80 default_server; return 444; } myproject/settings.py … -
Does wagtail tag {% slugurl 'page' %} work with Wagtail-localize?
I'm building a website with Django, Wagtail and Wagtail Localize. But when I'm load my website on "https://exemple.com/fr/" the slugurl tags generates links like href="/en/about/" I followed settings for urls.py : urlpatterns = urlpatterns + i18n_patterns( path("search/", search_views.search, name="search"), path("", include(wagtail_urls)), ) I also added middleware and others setting like LANGUAGES. Page are correctly translated and accessible with urls. The language code is detected because tag like {% if LANGUAGE_CODE == "fr" %} is working but this slugurl never work and always display "/en/about/" : <a href="{% slugurl 'about' %}" class="nav-links">about</a> Navigation isn't very fluid, because when you access a page you have to reselect the language each time. Is slugurl supposed to work with Wagtail-localize? -
Django: psychopg2 unique violation error anyway to fix this
I was updating my django projects version from 2.1 to 2.2 and it looks like some errors occurred with my staging database (I am assuming from all the answers that look similar to my problem).

django IntegrityError: Check constraint failed: new__blog_blogpage
I'm trying to build a blog using Django(wagtail cms) and have this error now that I'm not quite sure I understand. I'm assuming it has to do with my blog model. I've been googling for a day and half with no success. Many times the results are for NOT NULL constraint or ForeignKey error, but obviously my error is something different...

Django with datatables bootstrap 5 pagination is not working properly
I am learning Django with a sample web page. And I am trying to integrate Jquery DataTable with Bootstrap 5. The issue is, I have a total of 12 records in the DB.

How to sort a queryset by a attributes's choices
I have a model with a selectable month and year, like so: class Item(models.Model): MONTHS_CHOICES = [ ('JANUARY', 'January'), ('FEBRUARY', 'February'), ('MARCH', 'March'), ('APRIL', 'April'), ('MAY', 'May'), ('JUNE', 'June'), ('JULY', 'July'), ('AUGUST', 'August'), ('SEPTEMBER', 'September'), ('OCTOBER', 'October'), ('NOVEMBER', 'November'), ('DECEMBER', 'December') ] month = models.CharField(max_length=9, choices=MONTHS_CHOICES, default="JANUARY", db_index=True) year = models.IntegerField(default=0) (...) If I try to order the items by month and year Item.objects.all().order_by("-year", "month"). Logically the months will be be ordered alphabetically. What can I do to get the items ordered by the same order I have the months on MONTHS_CHOICES? Option B is just redo the models to include a DateField with only year and month, like this question here and order it by that field I also tried the solutions on this page but nothing worked to me. -

How to refactor a couple of fields from one model to another with FK relation
I currently have a model class Car(models.Model): name = models.CharField(max_length=20) manufacturer_name = models.CharField(max_length=20) manufacturer_url = models.URLField() Now I would like to extract the manufacturer information into its own model, so that I can get rid of redundant data. Like so: class Manufacturer(models.Model): name = models.CharField(max_length=20) url = models.URLField() class Car(models.Model): name = models.CharField(max_length=20) manufacturer = models.ForeignKey(Manufacturer, on_delete=models.CASCADE) Doing this however the Django migration tool just detects this as "delete fields" and "add fields". Can Django somehow do this migration automatically? Or will I have to write those migrations myself. It seems like a common use case, so I figured maybe Django has something in store for ootb. -
Django Bootstrap form-select...how do I find the selected value?
I have a Django application using Bootstrap form-select. This is filled up from a table like this: <div class="div-1 rounded bg-light text-dark "> {% trans "Active restaurant: " %} <select class="form-select-sm bg-light text-dark" aria-label={% trans "Select a restaurant" %} id="Selected_Restarurant"> <option selected>{% trans "Select a restaurant" %}</option> {% for restaurant in restaurants %} <option value="restaurant.name">{{ restaurant.name }}</option> {% endfor %} </select> </div> I have no idea how to address the value selected by the user in the form-select above. I need to run a filter on employee and update an employee table in the home.html template below to only show the employees of the selected restaurant. I know it has to do with the model and filters, that is also well documented, but how do I find the selected value and update the table below based on the selection?: <table class="table table-sm table-hover"> <thead class="table-success"> <tr> <!--th scope="col">{% trans "Employees" %}</th--> <th scope="col">{% trans "Restaurant" %}</th> <th scope="col">{% trans "First name" %}</th> <th scope="col">{% trans "Last name" %}</th> <th scope="col">{% trans "Username" %}</th> </tr> </thead> <tbody class="table-group-divider"> {% for employee in employees %} {% if employee.restaurant.name == "McDonalds in the bush" %} <tr> <!--td>{{ employee.user.first_name }}</td--> <td>{{ employee.restaurant.name }}</td> <td>{{ … -

Django ManifestStaticFilesStorage throwing Value Error
I am attempting to ensure that the cache is refreshed whenever I spin up a new instance in Django. I have implemented the following custom storage class to disable the strict handling of manifest files: from django.contrib.staticfiles.storage import ManifestStaticFilesStorage class NonStrictManifestStaticFilesStorage(ManifestStaticFilesStorage): manifest_strict = False This is used in conjunction with the setting: STATICFILES_STORAGE = "myapp.custom_storages.NonStrictManifestStaticFilesStorage" While everything appears to function correctly, I encounter a ValueError when a file does not exist, despite having set manifest_strict = False. This error was not expected under these circumstances. Could someone assist me in debugging this issue? As a temporary solution, deleting the problematic file resolves the error, but this is prone to future errors. For instance, if someone inadvertently removes a CSS file while cleaning up the code, it could disrupt the backend server, which must be avoided. -

Django Prefetch object with generic relation
As stated in the documentation: class Prefetch(lookup, queryset=None, to_attr=None) The Prefetch() object can be used to control the operation of prefetch_related(). The queryset argument supplies a base QuerySet for the given lookup For example, it can be used to specify the columns from the related object to SELECT, by using only(): Author.objects.prefetch_related(Prefetch("hometown", City.objects.only(["name"])) However, when prefetching the objects related through a generic relation, what model should be passed to the queryset param of Prefetch? I can't see any references to that on the docs nor SO. Something like: Prefetch("foo", GenericRelation.objects.only(["title"])) -

However, only one of the two statements is currently displayed. js: $("#id_base-0-show_null").change(function () { var show_null_value = document.querySelector('input[name=base-0-show_null]:checked').value; var checked_0 = document.getElementById('id_base-0-show_null_0').checked; var checked_1 = document.getElementById('id_base-0-show_null_1').checked; console.log(show_null_value, checked_0, checked_1); **currently doesn't do anything** }); exporter.py: def get_last_values_of_target(self, target_type, target_name): ... def get_zero_values_of_target(self, target_type, target_name): ... manual_input.py: def get_last_values_of_target(request): if is_ajax(request): target_type = int(request.POST['target_type']) target_name = request.POST['target_name'] exporter = Exporter() exporter.station = target_type values = exporter.get_last_values_of_target(target_type, target_name) **here is the current single exporter where i'm trying to add a second one (get_zero_values_of_target)** return HttpResponse(simplejson.dumps({'values': values}), 'application/javascript') else: return HttpResponseBadRequest("Not allowed") template: {% block content %} <form action="" method="post" id="manual_input_form" name="manual_input_form"> {% csrf_token %} <div class="timeDiffer"> {% for base_form in base_formset %} *** <div class="{% if base_form.non_field_errors %}error {% else %}showDiff{% endif %}"> <div>{{ base_form.show_differences.label_tag }}{{ base_form.show_differences }}</div> </div> {% if base_form.show_differences %} <div class="{% if base_form.non_field_errors %}error {% else %}showNull{% endif %}"> <div class="flex">{% trans base_form.show_null.label_tag %}{{ base_form.show_null }}</div> </div> {% endif %} {% endfor %} <input type='hidden' … -

CSS on the site is not visible
I'm working on a project using Django. I imported HTML files and created a Base HTML. I placed CSS and images in a folder named 'static' and imported them, but the CSS is not appearing on the site, only the HTML. Would you like me to share the code? I try to change something on setting.py -
How can I troubleshoot an authentication issue?
When making a request to http://127.0.0.1:8000/auth/users/reset_password/. The endpoint works only if i include ""rest_framework_simplejwt.authentication.JWTAuthentication" at(DEFAULT_AUTHENTICATION_CLASSES) but not when using my Custom authentication "passportBackend.custom_auth.JWTOrOAuth2Authentication".I think the documentation of rest_framework_simplejwt it returns None when permission is not required. from rest_framework.authentication import BaseAuthentication from rest_framework_simplejwt.authentication import JWTAuthentication from oauth2_provider.contrib.rest_framework import OAuth2Authentication from rest_framework.exceptions import AuthenticationFailed class JWTOrOAuth2Authentication(BaseAuthentication): def authenticate(self, request): # Try authentication additional_info = request.META.get("HTTP_X_ADDITIONAL_INFO") # # DRF OAuth2 # print(additional_info) if additional_info == "OAuth2": oauth2_authentication = OAuth2Authentication() oauth2_user, oauth2_auth = oauth2_authentication.authenticate(request) if oauth2_user is not None: return oauth2_user, oauth2_auth # # Simple JWT # elif additional_info == "jwt": jwt_authentication = JWTAuthentication() jwt_user, jwt_token = jwt_authentication.authenticate(request) if jwt_user is not None: return jwt_user, jwt_token return None def authenticate_header(self, request): # Override this method if needed pass "DEFAULT_AUTHENTICATION_CLASSES": ( "passportBackend.custom_auth.JWTOrOAuth2Authentication", ), How can I troubleshoot an authentication issue with my custom JWTOrOAuth2Authentication class ? -
How to connect to the existing database through NGINX?
I have a project what I need to start with Docker. I've successfully created images and containers of Django, NGINX and postgreSQL, so the project starts correctly. I noticed that when I try to login to the admin panel, Django raises OperationalError at /admin/login/ connection to server at "database" (192.168.144.2), port 5432 failed: fe_sendauth: no password supplied. Everything worked fine without nginx, but now I cannot access to the database. As I understand the problem, I need to change nginx.config, but I tried almost everything and still cannot figure this out. Seems like postgreSQL doesn't see my user maybe. My code snippet below. uwsgi.ini [uwsgi] wsgi-file = config/wsgi.py strict = true socket = :8000 protocol = http master = true no-orphans = true die-on-term = true lazy-apps = true processes = 4 threads = 8 enable-threads = true max-requests = 500 reload-on-rss = 1024 worker-reload-mercy = 60 harakiri = 60 harakiri-verbose = true vacuum = true post-buffering = 1048576 buffer-size = 65535 nginx.conf worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; include /etc/nginx/uwsgi_params; server { listen 80; server_name localhost; location / { proxy_pass http://django:8000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header …
