Why am I getting 'pg_config executable not found' when deploying my web app using Vercel?
I'm trying to use Psycopg2 with Railway to connect django to postgres using this tutorial: https://dev.to/dennisivy11/easiest-django-postgres-connection-ever-with-railway-11h6.

Is there a convention for returning an empty template in Django when making HTMX calls?
There are cases where I would like to not return any HTML in my view. Is there a good way to do it apart from returning a blank html file? Here is what I have currently: views.py def get_suites(request): address = request.GET.get('address') rental_units = Rental_Unit.objects.filter(address__address=address).order_by('suite') # return empty html requests if len(rental_units) > 1: return render(request, 'suite_list.html', {'rental_units': rental_units}) else: return render(request, 'empty.html') suite_list.html <label for="suite">Suite</label> <select name="suite" id="suite"> <option value="all">All</option> {% for rental_unit in rental_units %} <option value="{{rental_unit.suite}}">{{rental_unit.suite}}</option> {% endfor %} </select> main.html <label for="address">Address</label> <select name="address" id="address" hx-get="/get_suites" hx-target="#suite-wrapper"> <option value="all">All</option> {% for address in addresses %} <option value="{{address}}">{{address}}</option> {% endfor %} </select> <div id="suite-wrapper" style="display:inline"></div> -
How can I fix an 'invalid response' when using Django session and AJAX for ecommerce platform?

Streaming Chat completion using langchain and websockets

User defined user permissions
I'm not even sure how to fully ask this question so my googles haven't turned up much. So I have users, (obv) and they have an entity they're gonna be able to populate called a wallet. A user should have read write and delete permissions on a waller they create Naturally superadmins should have access to everything. But I want the users to be able to give other users read and / or write access. But regular staff should also have access. Do I just create a foreign key on the wallet populated with the user id's and boolean for read, write and delete access? Assuming I do that how do I handle Staff and super admin access? Do I like set up a view for a list of wallets that checks to see if you're an admin or staff and if not then checks if you have access and only displays those? And then only allow you to edit or delete if you have those boolean set? Does that make sense? -

Why does the built-in "with" template tag in django result in duplicate queries
In the django docs for the "with" template tag, it says that this tag.. is useful when accessing an “expensive” method (e.g., one that hits the database) multiple times. However, when I use it in my own template, I've observed (using django debug toolbar) that each time I call the variable that I create using the "with" template tag, it results in duplicate queries to the database if I perform an operation on that variable within another template tag. Why is this the case? Shouldn't I be able to do things to that variable without it querying the database? Below is my abridged and simplified code. Background I have three models: ## models.py class Contributor(models.Model): name = models.CharField(max_length=100) class Contribution(models.Model): contributor = models.ForeignKey( Contributor, on_delete=models.RESTRICT, related_name='contributions' ) class ROLE_CHOICES(models.TextChoices): A = 'AUTHOR', _('Author') C = 'COAUTHOR', _('Co-Author') E = 'EDITOR', _('Editor') V = 'VOICE', _('Voice Actor') S = 'AUDIO', _('Audio Engineer') role = models.CharField(max_length=10, choices=ROLE_CHOICES.choices) class Scenario(models.Model): title = models.CharField(max_length=200) contributions = models.ManyToManyField( Contribution, related_name='contributions' ) The template is associated with a class-based detail view: ## views.py class ScenarioDetailView(generic.DetailView): model = Scenario Here is my custom template tag code: ## custom_tags.py @register.filter def only_role(scenario, test_role): return scenario.contributions.filter(role=test_role) Here is my … -
How do I combine multiple sorting/filtering logic in Django in efficient way?
I am trying to make a site that supports searching/sorting/filtering at the same time. I did it in the 'if/elif' logic and it works! But it doesn't seem to be so efficient (from perspective of copying the code many times and inability to change something fast). As you can see in code examlpe below, I just specify these conditions for each possible case, such as: "with filter1, but without filter2 and filter3"; "with filter1 and filter2, but without filter3" and so on. As you can imagine, adding filters 4 and 5 sounds like a nightmare now, to be able to redo all this logic. Can you please share your thougths on how to do in a better way? I'm new to Django, so looks like I'm doing something wrong here Here is how my main view inside views.py looks like: class ResultsView(LoginRequiredMixin, ListView): model = Ads paginate_by = 9 template_name = 'library.html' #GET SEARCH def get_queryset(self): query_search = self.request.GET.get('search') query_sort = self.request.GET.get('sort_by') query_filter = self.request.GET.get('filter_by_language') query_search_username = self.request.GET.get('search_username') #search=YES, sort=NO, filter=NO if query_search and not query_sort and not query_filter: object_list = self.model.objects.filter(Q(headline__icontains=query_search) or Q(promoted_url__icontains=query_search)) elif query_search_username: #and not query_sort and not query_filter: object_list = self.model.objects.filter(Q(username__iexact=query_search_username)) #search=YES, sort=NO, filter=YES elif query_search … -

Elasticsearch Highlight result missing string
I am trying to use Elasticsearch's highlighting feature to highlight certain words from a text field. The text can be short or long (over 300 chars sometimes). Here is the highlight field passed to search function: def search(self): highlight = { "fields": { "content": { "type": "plain", "number_of_fragments": 0, } } } s = super(FacetedCustomSearch, self).search() return s.extra(highlight=highlight) As you can see below, the highlighted text is missing the - 1 POUND BAG string at the end. This usually happens when the text is over ~100 chars and sometimes with special characters like ! or / or - content: YOUR OFFICEKITCHEN - TASTING KITCHEN - SWEET CHILI HABANERO - GOURMET HANDMADE CRAFT MEAT SNACK - 1 POUND BAG highlighted content: YOUR OFFICEKITCHEN - TASTING KITCHEN - SWEET CHILI HABANERO - <em>GOURMET HAND</em><em>MA</em>DE CRAFT MEAT SNACK So far, I have tried to tweak the number_of_fragments (setting it to 0) and fragment_size and set the type to plain. Nothing seems to fix this issue. Any suggestions? Using elasticsearch-dsl 7.4.0 -

Understanding Nginx Logging: Does $request_time include Django backend response time?
I am checking the performance and response times of a web-app and the parties involved in it. I have a question regarding the logging that nginx makes of api rest requests to the backend of the web-app (React-Django). Nginx has the ability to log the $request_time to /var/log/nginx/access.log when serving a request from the backend. The question is: does it contain within that time in seconds the time that the Django backend takes to respond to the request? This is not clear to me from reading the documentation Nginx log_format. In what I tested, django responds to a request in 30 ms and Nginx logs that request as served in 33 ms. Do those 33 ms contain the 30 ms that django takes or are they separate? or are they only referring to the handling that Nginx can do (i.e. manage the request in a queue if there is a lot of service demand)? Thanks in advance! -
How can I retrieve a Django model element by name, regardless of text case?
How can i get element by name despite of text register. for example in my models i have element with user_name equal to "hello world" and i want get this element. So i write: User.objects.get(user_name=name) It's working if name equal to "hello world", but if name equal to "Hello World" or "hElLO wOrLD" then it's not working. I can use name.lower() but if user_name from models equal to "HELLO WORLD" then it's not working again. -
Issue with "delete" functionality in Django admin inline formset
I'm experiencing an issue with the "delete" functionality in my Django admin inline formset. I have a custom template for rendering the formset, and I've added a element with the class "delete" to allow users to delete rows. However, the delete functionality doesn't seem to be working as expected. tabular.html {% load i18n admin_urls static admin_modify %} <div class="js-inline-admin-formset inline-group" id="{{ inline_admin_formset.formset.prefix }}-group" data-inline-type="tabular" data-inline-formset="{{ inline_admin_formset.inline_formset_data }}"> <!-- ... --> <table class="table table-centered table-nowrap mb-0 rounded inline"> <thead class="thead-light"> <tr> <th class="original"></th> <!-- ... --> {% if inline_admin_formset.formset.can_delete and inline_admin_formset.has_delete_permission %} <th>{% translate "Delete?" %}</th> {% endif %} </tr> </thead> <tbody> {% for inline_admin_form in inline_admin_formset %} <!-- ... --> <tr class="form-row {% if inline_admin_form.original or inline_admin_form.show_url %}has_original{% endif %}{% if forloop.last and inline_admin_formset.has_add_permission %}empty-form{% endif %}" id="{{ inline_admin_formset.formset.prefix }}-{% if not forloop.last %}{{ forloop.counter0 }}{% else %}empty{% endif %}"> <td class="original"> <!-- ... --> </td> <!-- ... --> {% if inline_admin_formset.formset.can_delete and inline_admin_formset.has_delete_permission %} <td class="delete"> {% if inline_admin_form.original %} {{ inline_admin_form.deletion_field.field }} {% endif %} </td> {% endif %} </tr> {% endfor %} </tbody> </table> <!-- ... --> </div> Image Preview of the issue I suspect that there might be missing JavaScript or CSS code that handles the … -
Field 'id' expected a number but got <QueryDict
This is a common error on stack overflow but I cannot draw similarities with their errors and mine. A number is expected in the id column of the database(automatically made by django) but a query dict was put in instead Model: class Price(models.Model): HourlyPrice = MoneyField(default_currency="GBP",max_digits=19,decimal_places=3,null=True,blank=False) # price per hour DailyPrice = MoneyField(default_currency="GBP",max_digits=19,decimal_places=2,null=True,blank=True)# price per day WeeklyPrice = MoneyField(default_currency="GBP",max_digits=19,decimal_places=2,null=True,blank=True)# price per week MonthlyPrice = MoneyField(default_currency="GBP",max_digits=19,decimal_places=2,null=True,blank=True)# price per month View: def test(request): if request.method == 'POST': form = Price(request.POST) form.save() return render(request,'app/index.html', { 'title':'Home Page', 'year':datetime.now().year, } ) else: form = TestPrice(request.GET) context = { 'form': form, } return render(request,'app/test.html',context) Template: {% extends "app/layout.html" %} {% block content %} <form method="post" action=""> {% csrf_token %} <table> {{form}} </table> <button type="submit">Submit</button> </form> {% endblock %} Thank you for your time -

This specific filter sometime return null result but what I want is to catch the first() result without specific filter if no result return with. date_filter = Q(start_date__lte=OuterRef('object_start_date'), end_date__gte=OuterRef('object_start_date')) | \ Q(start_date__lte=OuterRef('object_start_date'), end_date=None) The query where i use this filter data_subquery = Object.objects.filter(date_filter).filter(user=OuterRef('user')).distinct() This subquery is used here next : main_subquery = Main.annotate(role=Subquery(data_subquery.values('role__name')[:1])) I've to anonymized data but the goal is to understand the need .... The filter subquery *datefilter *should be used if data_subquery return something ... else I don't need this filter and want to replace .disctinct() by .first() THanks for your help :) I've got a function to return specific data depending on user and date given in parameters ... or first one ... but I don't know how to use function into subquery ;) I tried to add : if len(data_subquery) == 0: data_subquery = Object.objects.filter(user=OuterRef('user')).filter() But it can't work with subquery :( -
poetry's 'run' stopped working claiming manage.py is missing
I have been using the run command for a year to perform all kinds of admin work, in this precise manner (i.e. with a dot): poetry run ./manage.py runserver and suddenly it no longer works, saying: $ poetry run ./manage.py runserver Command not found: ./manage.py But the file is there, and is executable: $ file manage.py manage.py: Python script, ASCII text executable witha proper #! /usr/bin/env python I know there's another way, namely: $ poetry shell followed by $ ./manage.py runserver but I feel a little stupid having to work around it =) I have recreated the virtual environment, but to no avail. The problem must be somewhere else, is my shell is missing something or poetry's setup? I did reinstall the system after all, but that wasn't a first time of so doing.. Thank you for your time! -
how to filter dropdown values based on the value of other dropdown in django

Why are my media files not being served in Django application with nginx?
I have a problem with my Django application which is deployed using gunicorn and nginx. I have a model for storing images in my sqlite database. class Image(models.Model): image_file = models.ImageField(upload_to="fucking_scraper/files/item_photos") item = models.ForeignKey(Item, on_delete=models.CASCADE) Here is my urls.py file urlpatterns = [ path("admin/", admin.site.urls), path("", include("fucking_scraper.urls")), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) and here are parts of settings.py file, related to serving files BASE_DIR = Path(__file__).resolve().parent.parent MEDIA_URL = "/media/" MEDIA_ROOT = "" STATIC_URL = "static/" STATICFILES_DIRS = [os.path.join(BASE_DIR, "fucking_scraper", "static", "fucking_scraper"), os.path.join(BASE_DIR, "fucking_scraper", "files", "item_photos")] STATIC_ROOT = os.path.join(BASE_DIR, 'static/') On a deployed website images are not displayed. I assume there is a problem with nginx configuration because before deployment it was working correctly in a debug mode. Here is how it looks like: server { listen [::]:80; server_name fwebsite.org; location /static/ { root /home/django/fwebsite.org; } location /media/ { root /home/django/fwebsite.org/fucking_scraper/files/item_photos/; } location / { include proxy_params; proxy_pass http://unix:/home/django/fwebsite.org/fucking_website.sock; } } I tried setting up location /media/ following instructions found on the internet but it didn't work for me and I am currently stuck.
