Why am I getting NoReverseMatch Error - Django
I'm having a reverse error in Django when visiting another URL "comment_post_view" The error is coming from when I visit the comment_post_view page; I'm thinking maybe it's because of the username in url, but I don't know how to go on with it. How can I get it done? URL path('p/<username>/status/<post_id>/', comment_post_view, name='comment_post_view'), path('settings/archive-post/', archive_post_view, name='archive_post_view'), path('archive-post/<id>/', archive_view, name='archive_view'), VIEWS.PY @login_required def comment_post_view(request, username, post_id): page_title = "Post Comment" username_url = get_object_or_404(User, username=username) user_post = get_object_or_404(Post, pk=post_id, poster_profile=username_url) # All users following posts user_profile = request.user.profile posts = Post.objects.filter( Q(id=user_post.id) ).order_by("?").select_related('poster_profile', 'poster_profile__profile').distinct() post_data = [] for post in posts: poster_profile = post.poster_profile.profile mutual_followers_qs = user_profile.following.filter( id__in=poster_profile.following.values_list('id', flat=True) ) post_data.append({ 'post': post, 'mutual_followers': mutual_followers_qs[:3], # You can select any number of followers here 'mutual_count': mutual_followers_qs[2:].count() }) ............................ @login_required def archive_post_view(request): page_title = "Archive Post" posts = Post.objects.filter( Q(is_hide=request.user) ).select_related('poster_profile', 'poster_profile__profile').distinct() post_data = [] for post in posts: poster_profile = post.poster_profile.profile post_data.append({ 'post': post, }) .......................... @login_required def archive_view(request, id): post = get_object_or_404(Post, id=id) if post.is_hide.filter(id=request.user.id).exists(): post.is_hide.remove(request.user) else: post.is_hide.add(request.user) return HttpResponseRedirect(request.META.get('HTTP_REFERER')) TEMPLATE archive_post_view.html {% for item in post_data %} {% if request.user == item.post.poster_profile %} <a href="{% url 'site:archive_view' item.post.id %}">Archive post</a> # Current user {% else %} # Error pointing to … -
How to Safely Upgrade a Package in Django (e.g., django-jalali from 1.0.2 to 2.0.0) Without Breaking Existing Code?
I'm currently working on upgrading an older Django project and I have both a specific and a general question about package upgrades. 🔍 Specific Question: I’m using django-jalali-date==1.0.2 in one of my older projects, and I'd like to upgrade it to 2.0.0 because of some important improvements and features. But before I do that, I want to be sure this won't break anything — especially in forms, models, templates, or static files ({{ form.media }}, template filters like |to_jalali, etc.). So, how can I safely compare the two versions, test compatibility, and ensure everything keeps working as expected? Are there any known breaking changes between these versions? How can I verify if imports like JalaliDateField, AdminJalaliDateWidget, or template tags still work? Any advice on testing or migration steps would be great! 🔁 General Question: More broadly, what’s the best way to safely upgrade any Python/Django package without risking regressions? What strategies do you use when upgrading major versions (e.g., from v1.x.x to v2.x.x)? For example: Do you manually check changelogs and diffs? Do you run tests or use tools like pipdeptree, pytest, or diff tools? Do you create a staging environment first? Any tips for checking backward compatibility (BC)? I’d … -
Issue with Modelform
This is what I got after coding my ModelForm What could have caused that, I kept trying to debug it, but everything seems right, didn’t know where the errors are coming from This was the error I got after running the server, the first form worked out, as I was trying to redirect to another form, this error threw up raise ValueError ("ModelForm has no model class specified.") ValueError: ModelForm has no model class specified.

Django cannot create record with correct foreign key to CharField with spaces in middle - getting surrounded by single and double quotes like "'a a'"
First of all - I understand that CharField is rather bad primary key, but it's unique in-game name, good 2 use as-is in many places, and may contain spacees. And IMHO the problem will repeat with non pkey field anyway 3 models - source, and two references. The first reference works perfectly in admin UI with the same code, the second - unworkanle during creating record class PilotUsers(AbstractUser, PermissionsMixin): first_name = None last_name = None username = None ed_name = models.CharField(primary_key=True,max_length=60,null=False,blank=False,unique=True,verbose_name='Pilot name in Elite Dangerous', ) squadron_tag = models.ForeignKey('Squadrons', verbose_name='Frontier squadron tag', on_delete=models.PROTECT, default='----') email = models.EmailField(unique=True) USERNAME_FIELD = 'ed_name' REQUIRED_FIELDS = ['email'] objects = PilotUserManager() def __str__(self): return self.ed_name class Meta: app_label = 'common_pages' This is working in admin UI - image below class Cert(DetailsModel, AbstractCert): organizational_unit_name = models.ForeignKey('common_pages.PilotUsers', verbose_name='ED Pilot Name', on_delete=models.PROTECT) class Meta(AbstractCert.Meta): abstract = False swappable = swapper.swappable_setting("posts", "Cert") This class ActionFeed(models.Model): pkey = models.BigAutoField(primary_key=True) received = models.DateTimeField(verbose_name='Date-time') ed_name = models.ForeignKey('common_pages.PilotUsers', verbose_name='ED Pilot Name', on_delete=models.CASCADE) #skipped raw_data = models.JSONField(verbose_name='Raw Data', null=False) is unworkable during creating new record print (f'Pilot = {pilot}') record = ActionFeed(received= ts, ed_name=pilot, #skipped raw_data = entry) The error is Cannot assign "'Al L****]'": "ActionFeed.ed_name" must be a "PilotUsers" instance.

Why is `djlint` warning me to add `<meta>` tags even though the file is linted?
I'm working on a Django web project and using djlint to lint and format my HTML templates. I ran the following command to lint one of my templates: djlint html_files/analytics/reports/report_new.html And I got this output: Linting 1/1 files ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 00:00 html_files/analytics/reports/report_new.html ──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── H030 3:0 Consider adding a meta description. <html lang="{{ lang H031 3:0 Consider adding meta keywords. <html lang="{{ lang Linted 1 file, found 2 errors. Even though it says "found 2 errors", the file is actually linted and formatted just fine. There’s no crash, and the formatting is applied. What I want to understand: Why are these tagged as errors, when they’re really just recommendations? Should these be treated as warnings or ignored? Is it best practice to always include <meta name="description"> and <meta name="keywords"> in Django templates — even for internal dashboards? How can I suppress or ignore these suggestions if I don’t want to include them? Let me know if there's a way to configure djlint to stop flagging these without affecting actual linting or formatting. What I’ve tried: I checked the official djlint documentation, and these are listed under SEO-related suggestions. I also tried this command and it worked to silence the warnings: djlint html_files/analytics/reports/report_new.html … -

How to correctly add a custom '--dry-run' argument to a Django Extensions `runjob` command?
I have a custom Django management job created using django_extensions that deletes old database records. To avoid unintended deletions, I want to add a --dry-run argument to simulate deletions without actually removing data. However, when I execute the command with: uv run python manage.py runjob delete_recordings --dry-run I receive this error: manage.py runjob: error: unrecognized arguments: --dry-run Here's how my simplified job class currently looks: from django_extensions.management.jobs import HourlyJob import logging logger = logging.getLogger(__name__) class Job(HourlyJob): @classmethod def add_arguments(cls, parser): parser.add_argument( '--dry-run', action='store_true', help='Execute the job in simulation mode without deleting any data.', default=False, ) def execute(self, *args, **options): dry_run = options.get('dry-run', False) if dry_run: logger.info("Executing in DRY-RUN mode.") # Logic here to delete records or simulate deletion based on dry_run I followed the Django Extensions documentation to add a custom argument (--dry-run). I expected that when running the command with --dry-run, it would recognize the argument and simulate the operation, logging the intended deletions without performing them. However, the command line returns an error indicating that the argument is not recognized. It seems that Django Extensions isn't picking up the custom argument defined in my job class. What is the correct way to add a custom argument (--dry-run) to … -
assign a custom field order_sl
I'm working with a Django model where I need to assign a custom field order_sl that should increment from the last existing value with a specific filter. Here's what I'm doing currently: prev_ordr = Order.objects.filter(abc).values("order_sl").first() if prev_ordr: new_order_sl = prev_ordr.get("order_sl") else: new_order_sl = 100000 ins.order_sl = F("order_sl") + (new_order_sl + 1) ins.save() ins.refresh_from_db() But I believe this approach is problematic: It pulls the last value into Python instead of handling it in the DB. It’s not thread-safe and likely to break under race conditions if multiple inserts happen at the same time. I'm using PostgreSQL, and I want to ensure that each new row gets a unique, sequential order_sl based on the highest existing value or a dedicated sequence. The order_sl field is not the primary key, and I don’t want to make it an AutoField. ❓ What’s the best, Django-safe, PostgreSQL-optimized way to handle this? Would a raw SQL sequence be better? Or should I use select_for_update() with a transaction block? Thanks! -
Understanding F expression in Django
What I have done is - prev_ordr = Order.objects.filter(abc).values("order_sl").first() if prev_ordr: new_order_sl = prev_ordr.get("order_sl") else: new_order_sl = 100000 ins.order_sl = F("order_sl") + (new_order_sl + 1) ins.save() ins.refresh_from_db() return But I'm not sure about this, this is loading the previous value into the python and not directly managing the database (i think so), as it should be in the case of F expression and it may fail race condition. Can you let me know the correct way, I have to increase the value by 1 (from the last row) in the new row. Thanks -

How to intercept a form submit in websocket connection?
I have "inherited" a piece of code from a chat application. I would like to add some custom checks on the user input upon submission, allowing the submit to be aborted on client side if necessary. I have created a submit handler javascript function in order to execute the checks and transformations, including preventDefault as first instruction: async handleSubmit(event) { event.preventDefault(); // Prevent default form submission ... I have linked the handler to the form: <form class="pg-chat-input-bar" ws-send @submit="handleSubmit($event)" enctype="multipart/form-data" > Yet, no matter what, the form is submitted immediately when the submit button is pressed. The server receives the form in parallel to / before the handler being executed. I can assess that the handler is triggered and does what it is supposed to do but unfortunately the form has already been submitted. I tried @submit.prevent, @submit.stop and even combined both but it doesn't change the outcome. I found many posts asking to capture/intercept/interrupt a form submit but the solutions are as simple as what I tried. What am I doing wrong? As I am not starting from scratch I would prefer modify the code as little as possible and use what is already there. Could it be related … -
How to compare a DecimalField value in Django templates for conditional logic?
I'm working on a Django project where users have an Account model with a DecimalField named account_balance. I'm trying to conditionally show a KYC verification link if the user's balance is exactly 100, and show an error if it's less than that. Here’s my setup: class Account(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) account_balance = models.DecimalField(max_digits=10, decimal_places=2) class KYC(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) slug = models.SlugField() views.py: def settings(request): kycs = KYC.objects.filter(user=request.user) context = { "kycs": kycs, } return render(request, 'public_pages/settings.html', context) template: {% for kyc in kycs %} <p>Your identity is important to the community</p> {% if kyc.user.account.account_balance == 100 %} <a href="{% url 'Kyc_Form' kyc.slug %}">Update KYC</a> {% elif kyc.user.account.account_balance < 100 %} <div class="alert alert-danger"> You need at least 100 coins before applying for KYC. </div> {% endif %} {% endfor %} But this block never renders either the button or the error message. The only thing I see is the static text: <p>Your identity is important to the community</p> I tried printing the balance outside the logic: <p>Balance: {{ kyc.user.account.account_balance }}</p> And it shows something like 100.00. I assume it's a Decimal issue. How can I properly compare a DecimalField like account_balance in the Django template to check … -

How to store the refresh token in HttpOnly cookie with Google OAuth2 (PKCE flow) in Django?
I'm using Django with drf_social_oauth2 and oauth2_provider for Google OAuth2 authentication. I’ve successfully implemented the PKCE authorization flow. Step 1: Frontend redirects to: GET /api/v1/o/authorize/?client_id=<client_id>&response_type=code&redirect_uri=http://127.0.0.1:5173/callback&code_challenge=<challenge>&code_challenge_method=S256 Step 2: Frontend exchanges code at: POST /api/v1/o/token/. Backend responds with: { "access_token": "...", "expires_in": 36000, "refresh_token": "...", ← this is what I want to move into a cookie ... } My configuration: # urls.py from django.contrib import admin from django.urls import path, include urlpatterns = [ path("admin/", admin.site.urls), path("api/v1/o/", include("oauth2_provider.urls", namespace="oauth2_provider")), ] # settings.py (snippets) INSTALLED_APPS = [ ... 'oauth2_provider', 'social_django', 'drf_social_oauth2', ] AUTHENTICATION_BACKENDS = ( 'django.contrib.auth.backends.ModelBackend', 'social_core.backends.google.GoogleOAuth2', 'drf_social_oauth2.backends.DjangoOAuth2', ) SOCIAL_AUTH_GOOGLE_OAUTH2_KEY = '<your-client-id>' SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET = '<your-client-secret>' REST_FRAMEWORK = { "DEFAULT_AUTHENTICATION_CLASSES": ( "oauth2_provider.contrib.rest_framework.OAuth2Authentication", "drf_social_oauth2.authentication.SocialAuthentication", ), } LOGIN_REDIRECT_URL = "/" What works: PKCE is working. Google OAuth2 authorization is integrated using social-auth-app-django and drf-social-oauth2. I can extract the original Google access_token from the user's social_auth.extra_data. What I want: I want to store the refresh_token in a secure HttpOnly cookie instead of returning it in the JSON response — to reduce XSS risks. I would be grateful for any advice, code examples on how to solve this, or references to sources where a solution can be found. -

How to handle error reporting and validation of uploaded files using django-formset?
Short version I'm using django-formset to create a contact form that includes a file upload field. When an incorrect file is selected, no error message is shown. When uploading the form with an incorrect file, the field is cleared and a "Please either submit a file or check the clear checkbox, not both" error is thrown for this field, which is inaccurate. Because the field is cleared I cannot validate it anymore and return a descriptive error message. Is there any documentation that describes how this should be handled? Long version I want to custom validate file uploads while using django-formset. Initially, I'm mainly looking to validate image files, but later other types as well. Problem one Error messages do not show when selecting invalid files. Upon selecting a file that is too large, nothing happens (no errors are shown, no POST request is sent, GUI is not updated). Here I would at least expect a message to display "File size is too big" or so. When selecting a file with an invalid extension, a POST request is sent and the GUI is updated to show the selected file (with or without a valid thumbnail). However, no error message is … -
UnicodeDecodeError when connecting to PostgreSQL using psycopg2, despite UTF-8 encoding everywhere
I'm trying to connect to a local PostgreSQL database using psycopg2 in Python. Here's the code I'm using: import psycopg2 params = { 'dbname': 'database_name', 'user': 'user_name', 'password': 'mypassword', 'host': 'localhost', } for k, v in params.items(): print(f"{k}: {v} (type={type(v)}, encoded={v.encode('utf-8')})") try: conn = psycopg2.connect(**params) print("Connexion OK") conn.close() except Exception as e: print("Connexion Erro") print(type(e), e) The printed output confirms that all parameters are strings and UTF-8 encoded. However, I still get the following error: Connexion Erro <class 'UnicodeDecodeError'> 'utf-8' codec can't decode byte 0xe9 in position 103: invalid continuation byte I also checked the server and client encoding on PostgreSQL using: SHOW server_encoding; SHOW client_encoding; Both return UTF8. Given that all inputs are UTF-8 and the database is configured for UTF-8, I don't understand why this error occurs. Has anyone encountered this before or has an idea of where this byte 0xe9 might come from? What else should I check? -
Seeking a Clear Roadmap for Learning Python and PHP as a Junior Developer (with Remote Work Goals) [closed]
Seeking a Clear Roadmap for Learning Python and PHP as a Junior Developer (with Remote Work Goals) Body: Hello everyone, I’m a junior developer currently learning both Python and PHP, and I find myself a bit confused about which path to focus on or how to organize my learning. I'm still a student, and my primary goal is to gain enough skills to start working remotely from home — ideally through freelancing platforms or remote internships.

I’d like to understand: What steps should I take to build a solid backend skill set? What technologies or tools should I prioritize (e.g. databases, APIs, deployment)? Should I focus on one language or is it okay to learn both in parallel? What kind of projects should I build to gain real-world experience? What are the best freelancing platforms or websites for beginners? How can I showcase my skills effectively to land small jobs or internships?

How can I move the iterable value (radio) from the outer loop to the inner one, bypassing the inner loop iteration? How can I get the value (radio) of the outer loop. I have a nested loop that generates additional fields. The value from the outer loop. I plan to get the value from the outer loop not 30 times - but how many times in the outer loop 5 times. How can I skip the inner iteration? I have been thinking for several days how to make such a scheme. I have a choices field. I am trying to insert section names between them.

Job hunting advice for a self-taught dev feeling stuck
I'm a self-taught full-stack web developer. I've been learning and building projects for about a year now using technologies like Python (Django) and React.js. Now that I feel somewhat confident with my skills, I think it's time to start looking for a job. But here's my problem, I genuinely don't know how to start the job hunting process. It feels overwhelming, and to be honest, I'm a bit frightened to take that first step. I’ve been procrastinating because I feel uncertain, and when I spoke with a friend who’s also learning, he said he feels the same way. I'm not sure what I should be doing right now: Should I be applying to junior roles directly? Do I need to work more on open source? How do I know when I’m “ready”? What’s the best way to approach recruiters or companies? If any of you have gone through this stage or have tips on how to get started with the job hunt—especially as a self-taught developer, I’d really appreciate your advice.
