nginx not serving static files for django, searching in an other folder
I am deploying my django project to server using Nginx and Gunicorn static files are not loading. 2023/11/07 05:17:42 [error] 68970#68970: *40 open() "/home/pau/perp2.0/perp/staticfiles/static/admin/js/core.js" failed (2: No such file or directory) The nginx is searching the file in /home/pau/perp2.0/perp/staticfiles/static/ but the directory for the static files is just /home/pau/perp2.0/perp/staticfiles without the last static my file configuration for nginx is this server { listen 80; server_name my_ip; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/pau/perp2.0/perp/staticfiles; } location / { include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } } and just in case my settings.py for the static files part is this: `# Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/1.10/howto/static-files/ STATIC_ROOT = os.path.join(PROJECT_ROOT, 'staticfiles') STATIC_URL = '/static/' DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField' # Extra places for collectstatic to find static files.

Bootstrap modal not sending a request to django view for rendering model form
I'm currently working on a django project that manages inventory of biological samples. I have a specimen details page that renders four tables with data associated with the selected specimen. In each of these tables I have an Edit button where the user can update a record associated with the specimen. Right now, when the button is clicked, a new page is opened and the update form is rendered. I'd like to use a bootstrap modal to create a popup of the form instead of having to go to a whole new page. I already created something similar on the home page for adding a new specimen record and it works great. For some reason tryin the same thing on the details page will not work. The modal does pop up, but the form does not render and it seems like the issue is that there is no request being sent to the edit_specimen url/view even though it is specified. Im wondering if it has to do with urls and the pk being in the url for this operation. I've tried several things and I can't get it to work. Any advice is appreciated as I am relatively new to … -

Check if Django is able to connect with given parameters or return an error message, instead of causing an internal server error (500)
I'm trying to build dynamic connections to databases. This because I just now and then have to query them to get some data. The sources change over time, so I'm not in favor of adding them to settings. Currently I have the following code: DBTYPE = ( ('postgres', ('PostgreSQL')), ('mysql', ('MySQL')), ('mysql', ('MariaDB')), ('oracle', ('Oracle')), ('mssql', ('MSSQL')), ('sqlite', ('SQLite')), ) URLTEMPLATES = ( ('postgres', ('postgres://{USER}:{PASSWORD}@{HOST}:{PORT}/{NAME}')), ('mysql', ('mysql://{USER}:{PASSWORD}@{HOST}:{PORT}/{NAME}')), ('oracle', ('oracle://{USER}:{PASSWORD}@{HOST}:{PORT}/{NAME}')), ('mssql', ('mssql://{USER}:{PASSWORD}@{HOST}:{PORT}/{NAME}')), ('sqlite', ('sqlite:///{HOST}')), ) dburl = [item for item in URLTEMPLATES if item[0] == self.engine] self.db_url = dburl.format(**template_values) dbsetting = dj_database_url.parse(self.db_url,conn_max_age=600,conn_health_checks=True,) database_id = self.name newDatabase = {} for conn in connections.all(): print(conn) try: newDatabase["id"] = database_id newDatabase['ENGINE'] = dbsetting['ENGINE'] newDatabase['NAME'] = dbsetting['NAME'] newDatabase['USER'] = dbsetting['USER'] newDatabase['PASSWORD'] = dbsetting['PASSWORD'] newDatabase['HOST'] = dbsetting['HOST'] newDatabase['PORT'] = dbsetting['PORT'] newDatabase['ATOMIC_REQUESTS'] = True newDatabase['TIME_ZONE'] = 'Europe/Paris' newDatabase['CONN_HEALTH_CHECKS'] = False newDatabase['CONN_MAX_AGE'] = 600 newDatabase['OPTIONS'] = {} newDatabase['AUTOCOMMIT'] = False connections.databases[database_id] = newDatabase cursor = connections[database_id].cursor() cursor.close() What I would like to achieve is, that when Django is unable to connect, it just responds with a message that connection could not be established.

celery beat ExpressionDescriptor.py get_full_description
I hope your day is going well. I've hit a bit of a snag with a Django project I’m working on. I'm relatively new to Django and would deeply appreciate it if you could spare a moment to help me troubleshoot an issue. I'm using Celery Beat for scheduling periodic tasks. I have a view in the admin where I check and set periodic tasks, but recently a strange error has appeared, and I can't locate the issue. Whenever I try to open any admin view with periodic tasks, I get this type of error: It indicates a problem with resolving the names of the crontabs: During handling of the above exception (invalid literal for int() with base 10: '0DAY'), another exception occurred: But I haven't changed anything in the database or modified anything with settings. Do you know how I can resolve this issue, or where to look for a solution? It's probably a default setup and nothing there is set or modified, and I also couldn't find any solution to my problem on the internet :( I'm using : django-celery-beat==2.5.0 Django==4.2.2 I do not have any external settings to celery beat in django project :( -
Password change form URL in Django admin cannot find user with correct ID
I'm having some trouble with my admin settings. I am using a custom user model (called Org, for context), and everything works perfectly in the admin except for the password change form. For clarity, I'm talking about the little form that says "Raw passwords are not stored, so there is no way to see this user’s password, but you can change the password using this form." However, when I click on "this form", I'm redirected back to the admin homepage, with the warning "Org with ID '40/password (40 being the ID)' doesn’t exist. Perhaps it was deleted?" Examples of inline and admin # all inlines look like this: class OrgContactInfoInline(admin.TabularInline): model = OrgContactInfo @admin.register(Org) class OrgAdmin(admin.ModelAdmin): inlines = [OrgContactInfoInline, OrgInfoInline, OrgLocationInline, ItemInline] add_form = CustomUserCreationForm form = CustomUserChangeForm model = Org ordering = ("-org_name",)``` Important forms class CustomUserCreationForm(UserCreationForm): password = forms.CharField( widget=forms.PasswordInput(), label=mark_safe( "Your password must:<br />-Be longer than 8 characters<br />-Have an uppercase and lowercase characters<br />-Use a special character/number" ), ) confirm_password = forms.CharField(widget=forms.PasswordInput()) class Meta: model = Org fields = ["org_name"] class CustomUserChangeForm(UserChangeForm): class Meta: model = Org fields = ["org_name"] URLs urlpatterns = [ #my urls path('', include('apps.homepage.urls')), path('accounts/', include('apps.accounts.urls')), path('mynonprofit/', include('apps.dashboard.urls')), #django urls path('accounts/', include('django.contrib.auth.urls')), … -

calling a view without passing request
I have a view that is called like this. def device_check(request, d, i): # A bunch of stuff the view does When i call this view by default it works perfect no issues, then i have another function that generates some data and tries to call that function to check and i keep getting the error that its not passing enough arguments, since i am trying to use it like this def test_function(request): test = device_check("test", "i-1799") And i understand the error is being caused because i am not passing it the request parameter like so device_check(request, "test", "i-1799") But i have no idea how i would pass it the request parameter from within another function. Is there a better way of doing this, or a way around that? -
Cannot Grab request.get_host() from Django Request to get real domain name
I use docker and nginx to run my system but I am hitting an issue now to where I would like to redirect client users of my system automatically to a subdomain. i.e. something like prod.example.com. This already works in my nginx config to duplicate access to the page, but I would like to map specific client urls to the subdomain, not the main one. Normally this would be simple in Django using something like: if not 'app.' in request.get_host(): redirect(f'app.{request.get_host()}') # example # get_host()=app | get_absolute_ur()=http://app/, meta: app But my nginx proxy pass uses an upstream variable, and it appears that is all that is posted through with the variables tried above. How can I get this done? upstream app { server web:8000; # appserver_ip:ws_port } server { server_name prod.example.com; listen 80; client_max_body_size 250M; # enforces HSTS or only content from https can be served. We do this in CloudFlare add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always; add_header Permissions-Policy "autoplay=(), encrypted-media=(), fullscreen=(), geolocation=(), microphone=(), browsing-topics=(), midi=()" always; location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://app; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_redirect off; proxy_headers_hash_max_size 512; proxy_headers_hash_bucket_size 128; } } -
Django CreateView within Navbar
I have a base_page.html which includes navbar (utilizing {% include %} tag). The idea is to place trigger (a tag in my case) within navbar which calls a CreateView globally (where the navbar displays) around a project. So far I managed to place an a tag which triggers CreateView displays a modal window with form. But problem is a View renders designed to render a single page that makes hard to use that CreateView within a project globally. Wondering if there is a way to use CreateView within a navbar everywhere it displays. {% load static %} <div class="logo_pic"><a href=""><img src={% static "img/navbar_icons/temp_logo.svg" %} alt="logo_pic"></a></div> <div class="nav_menu"> <div class="nav_menu_top"> <a href=""><img src={% static "img/navbar_icons/home_icon.svg" %} alt="home-button-icon"></a> <a href=""><img src={% static "img/navbar_icons/transaction_icon.svg" %} alt="transaction-icon-button"></a> </div> <div class="nav_menu_bottom"> <a id="openModalBtn"><img src={% static "img/navbar_icons/add_new_transaction_icon.svg" %} alt="new_transaction"></a> </div> <!-- Modal window --> <div id="myModal" class="modal"> <div class="modal-content"> <span class="close" id="closeModalBtn">&times;</span> <h2>Create new transaction</h2> <form method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Submit"> </form> </div> </div> </div> -

Cannot write to sqlite3 in docker container
I am starting to get my feet wet attempting to deploy a django/react app up on an EC2 instance. Everything is running fine on my personal Windows computer but when I pulled the code into the Ubuntu 22.04.3 container I got the following error: django.db.migrations.exceptions.MigrationSchemaMissing: Unable to create the django_migrations table (attempt to write a readonly database) As I said this worked fine on my Windows laptop but is not working in Linux. Is this an issue with Linux or my Dockerfile? I plan to eventually use a postgres instance once I am feeling confident, but maybe I should just do it?

Customizing Django Form based on model from 2 different models
I have the following 3 models in django. models.py ============= class Customer(models.Model): name = models.CharField(max_length=255, null=False, unique=True) class Service(models.Model): name = models.CharField(max_length=255, null=False) architecture = models.NameField() class customer_services(models.Model): customer = models.ForeignKey(Customer, on_delete=models.SET_NULL, null=True, related_name='customer_service_entries') service = models.ForeignKey(Service, on_delete=models.SET_NULL, null=True, related_name='customer_service_entries') start = models.DateField() end = models.DateField() I have the following forms forms.py ============== class CustomerForm(ModelForm): class Meta: model = Customer fields = ["name"] class CustomerServiceForm(ModelForm): class Meta: model = customer_services fields = ["service", "start", "end"] class ServiceForm(ModelForm): class Meta: model = Service fields = ["name", "architecture"] I am trying to have a form that i can add services to customers, and the issue i am running into is that the form will display only the fields from the CustomerServiceForm.
