Add custom field to wagtailadmin ModelAdmin
I'm trying to add a custom field to wagtail ModelAdmin, but not sure how to do that. I tried from wagtail_modeladmin.options import ModelAdmin, modeladmin_register from wagtail_modeladmin.views import EditView from django import forms from django.contrib.admin.utils import quote from wagtail.log_actions import registry as log_registry from dzen_wagtail.football_maps.models import FootballMap class FootballMapAdminForm(forms.ModelForm): extra_link = forms.URLField( label="Extra link", widget=forms.URLInput(attrs={"type": "button"}), ) field_order = ["tg", "name", "location", "history", "covering", "extra_link", "status"] class Meta: model = FootballMap fields = ["tg", "name", "location", "history", "covering", "extra_link", "status"] def __init__(self, *args, **kwargs): super(FootballMapAdminForm, self).__init__(*args, **kwargs) self.fields["extra_link"].initial = "https://example.com" class FootballMapEditView(EditView): def get_form(self): return FootballMapAdminForm(instance=self.instance) @modeladmin_register class FootballMapAdminSite(ModelAdmin): model = FootballMap menu_label = "Карта коробок" menu_icon = "circle-check" edit_view_class = FootballMapEditView def get_list_display(self, request): list_display = ["location", "status"] return list_display But looks like I go in wrong direction, and such can be achieved in ModelAdmin itself -
Django Postgresql ORM optimisation
I have a PostgreSQL view called view_sales_dashboard - this consists of several millions rows of daily sales data. In the Django view I want to present a table grouped by the products, with the columns as the total base_daily_pnl of different time periods - Daily, Month to date (MTD), Quarter to date (QTD), Year to date (YTD) and Inception to date (ITD) In order to try and limit the number of SQL queries I am creating 5 querysets to then generate the table. To improve the efficiency of this I investigated the logs and expected to see 5 SQL queries. However the logging shows 20 queries (5 product types * the 4 aggregate groupings + the daily series request). See below the Django code, ORM model and the logs. Can anyone advise 1.) why so many SQL queries are being triggered 2.) how to optimise? queryset_sales_all = SalesDashboard.objects.all() queryset_daily_products = queryset_pnl_all.filter(position_date__range=[latest_pnl_date_str, latest_pnl_date_str]).values('product').annotate(base_daily_pnl=Sum('base_daily_pnl'),base_lmv=Sum('base_lmv')) for daily in queryset_daily_product: matching_mtd = queryset_pnl_all.filter(position_date__range=[start_mth_str,latest_pnl_date_str]).values('product').annotate(mtd_pnl=Sum('base_daily_pnl')).get(product=daily['product']) matching_qtd = queryset_pnl_all.filter(position_date__range=[start_qtd_str, latest_pnl_date_str]).values('product').annotate(qtd_pnl=Sum('base_daily_pnl')).get(product=daily['product']) matching_ytd = queryset_pnl_all.filter(position_date__range=[start_year_str, latest_pnl_date_str]).values('product').annotate(ytd_pnl=Sum('base_daily_pnl')).get(product=daily['product']) matching_itd = queryset_pnl_all.filter(position_date__range=[start_itd_str, latest_pnl_date_str]).values('product').annotate(itd_pnl=Sum('base_daily_pnl')).get(product=daily['product']) daily['mtd_pnl'] = matching_mtd['mtd_pnl'] daily['qtd_pnl'] = matching_qtd['qtd_pnl'] daily['ytd_pnl'] = matching_ytd['ytd_pnl'] daily['itd_pnl'] = matching_itd['itd_pnl'] pnl_product = SummaryPnlProductTable(queryset_daily_product) Below is the ORM model: class SalesDashboard(models.Model): unqiue_id = models.IntegerField(primary_key=True) sales_id = models.CharField(max_length=50) base_daily_pnl … -

It is a good idea to put auth in TENANT_APPS in a multi-tenancy django app?
I'm preparing a multi-tenancy app with django. I need that a user only can access and manipulate the data of your own schema. For exemple, if a have domain_a and domain_b, some users should only acess domain_a data and another users only can access domain_b data, and never both. Cause this, I decide to put the auth apps inside tenant apps: SHARED_APPS = ( 'django_tenants', 'homecare_public', ) TENANT_APPS = ( 'homecare', 'account', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'rest_framework.authtoken', 'rest_framework_simplejwt', 'django_seed', 'drf_yasg', ) INSTALLED_APPS = list(SHARED_APPS) + [app for app in TENANT_APPS if app not in SHARED_APPS] TENANT_MODEL = 'homecare_public.Client' TENANT_DOMAIN_MODEL = 'homecare_public.Domain' As you can see, things like 'django.contrib.admin' and 'django.contrib.auth' are inside tenant_apps. I wanna isolate the schemas, where each one have their own users! So my question is: is this a good idea? -
Django prefetch within model method
So I have a Django model which is a foreign key for several other models. I want to add a method to my model and see if my instance of the model actually has any related objects. Two questions: I'd like to do this with one query, but I'm unsure how to use prefetch_related with "self". How do I do this? Is there a way to just return True or False if a related model exists? For example, should I just use first? (I seem to recall there being a "correct" way to do this, but it's been a while, and I may be remembering flask.) Code example: from django.db import models class Person(models.Model): # <fields> def has_device(self): # ***prefetch related phones and laptops*** if self.phone_set.first() or self.laptop_set.first(): return True return False class Laptop(models.Model): owner = models.ForeignKey(Person) # <fields> class Phone(models.Model): owner = models.ForeignKey(Person) # <fields> -

Django: Screening dangerous characters from text input
I have a Django app where a few of the forms support a text input with maximum lengths of either 50 or 250 characters. In all cases, the data entered will be stored in the backend DB and will be available for later viewing upon request. In all cases, I'm using the cleaned_data() method when collecting user inputs from the form. And in all cases, the data is such that most "special characters" are unnecessary. (There are a few I'd like to allow for convenience & flexibility, such as hyphens or parentheses, but beyond that alphas & digits should cover it.) Given all that, I'm looking to put an extra layer of screening on these fields to prevent injections. Particularly XSS but other malicious input as well. I'm thinking the simplest approach is to block/reject the more dangerous characters -- angle brackets, curly braces, and forward/backslashes being the most obvious. My questions are: Are there any other characters I should block/reject to guard against injection attacks? Or, would I be better off going the whitelist route instead? Define the full set of permissible characters and reject anything not in the list? Or -- is this whole idea of field-by-field screening … -
Social authentication (DRF + Djoser), "non_field_errors": ["Invalid state has been provided."] after POST request with state and code
I am following this video tutorial and trying to implement Google social authentication using DRF, djoser and React. I type this in browser (GET request): http://localhost:8000/auth/o/google-oauth2/?redirect_uri=http://localhost:8000 I have the response like this (I am not sure if this url is safe to share, but anyway I changed it slightly) { "authorization_url": "https://accounts.google.com/o/oauth2/auth?client_id=836198290956-fe0ilujf6e23l882oumgkufi8qm6fg3m.apps.googleusercontent.com&redirect_uri=http://localhost:8000&state=eNwMFCmEplYgbUTTP9nnrQ6MduAPxzDY&response_type=code&scope=https://www.googleapis.com/auth/userinfo.email+https://www.googleapis.com/auth/userinfo.profile+openid+openid+email+profile" } I enter this response to the browser, this redirects me to google sign in page.

Using difference() on Django model and then creating aggregation annotation
I have a Django app that imports data from a third-party source and allows me to map it to standardized data sets using a translation table. The translation table takes two values from the source data (manufacturer and model) and returns the model ID for the matching model in the standardized data. The reason for the translation table is that the model description isn't 100% consistent in the source data, so I might need to map 2 or 3 model #s in the source data to a single model # in the standardized model table. I have an interface that provides me the models in the source data that have not been matched to a model in the standardized data. I don't currently use a foreign key field in the Django model, so what I've been doing to get the list to feed to the template is mkt = MarketData.objects.all() mapped_mdls = MktModel.objects.all().values('mfr','mdl') mdl = mkt.values('equip_mfr','equip_model').distinct() \ .annotate(mfr=F('equip_mfr'),mdl=F('equip_model')).values('mfr','mdl').difference(mapped_mdls) \ .order_by('mfr','mdl') The values...annotate...values chain is to change the field names in the source data to match the lookup table. I am trying to add the total number of units represented by the manufacturer/model combo, which is contained in a field called … -

How to Configure a Reverse Proxy for a Django Project on GoDaddy with Apache to Hide Port 8000
I have a Django project that I've uploaded to a GoDaddy server running Apache. I’m using a domain with the .com extension, and I've started the Django development server with the command python manage.py runserver 0.0.0.0:8000. This makes the project accessible through the domain with port 8000 (e.g., www.example.com:8000). I would like to hide the port or route requests internally to port 8000 using a reverse proxy, but it’s not working. Additionally, when I try to access the site directly through the domain without specifying the port, it shows my folder structure instead of the Django application. Could you help me with configuring the reverse proxy or resolving the issue with accessing the Django project directly through the domain? I’ve attempted various commands and configuration setups in the .conf file to configure a reverse proxy and hide the port, but nothing seems to work -

I have verified that the migrations have been applied correctly both locally and in production. I used showmigrations and everything seems to be in order. I checked the production database via shell_plus and the model's table exists. I also created a record manually to ensure it works. My admin.py is configured correctly and looks identical in both the local and production environments. # admin.py from django.contrib import admin from myapp.models import MyModel @admin.register(MyModel) class MyModelAdmin(admin.ModelAdmin): list_display = ('field1', 'field2', 'field3') I cleared the browser cache and tried a different browser, but nothing changed. I can't figure out why the model doesn't appear in the admin in production. Any suggestions on what I might check or do to resolve this issue? -
How can I have a different method instead of user.is_authenticated?
I have an academy website , which has 3 different kinds of users. The first one is the staff that I handle with the admin panel. The second one is parents or people who are going to get some information about the academy. The third one is students who have a different panel. My question is how can I authenticate this students ? I mean we have a method that is {% user.is_authenticated %} but it isn't ok for me because I want to check a different model named "students" and I used this method for other places. I expect a different authentication system. Because the one which I used is for regular users and I want to check that if he is a student he can have access to the special panel. Please share your ideas. -
Socket IO is rejecting requests from Nginx proxy
I have this docker application running several containers. One of these containers is a Python application that can handle both socket io requests and normal HTTP requests. Django's ASGI handles HTTP/ASGI requests while python-socketio handles socket requests. Since there are 4 other applications like this which must all be server via Nginx, I have to specify namespace URLs for both the socket io and ASGI applications for all the applications. I am using the following configuration for the application: location /app/ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://app:8000/; # docker container name is "app" } location /app/socket.io/ { proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://app:8000/socket.io/; # docker container name is "app" proxy_read_timeout 86400s; proxy_send_timeout 86400s; } asgi.py import os import socketio from django.core.asgi import get_asgi_application os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings") django_application = get_asgi_application() from app.async_socketio.server import sio # noqa 402 # this allows Socket IO to handle requests by default to a # default path of /socket.io and forwards any other requests # to the Django application. application = socketio.ASGIApp(sio, django_application) # just so all my socket event handles can … -
Django reduce number of returned rows for chart
I have model with timestamp=DateTimeField() and some extra numerical data. In table I stores data from sensor collected each minutes. I have views returning chart with data from mentioned table which is parameterize by start_date and end_date. Chart works great for data from max few days period, but everything "explode" when period is longer (do many records). I don't want to reinvent the wheel. I want return only n representatives records for time period (for example with avg value). I believe that my problem is common one, but I can not google ready solution for it. -
Django DateField persistence
I have a model / Form / view for a request that works well, but when I want to update a request all the fields are loaded except the due_date field (with a date widget) witch remains empty. If I don't pay attention I validate and the due_date become None. I would like it to load the date that was saved during creation by default and then I modify it or not. Here is the code. Model class Request(models.Model): thematic = models.ForeignKey( Thematic, on_delete=models.SET_NULL, null=True, blank=True, verbose_name="Thématique", ) context = models.ForeignKey( Context, on_delete=models.SET_NULL, null=True, blank=True, verbose_name="Contexte", ) technical_element = models.CharField( max_length=255, verbose_name="Élément technique", blank=True, null=True ) due_date = models.DateField(verbose_name="Date d'échéance", blank=True, null=True) def __str__(self): return self.context class Meta: verbose_name = "Request" verbose_name_plural = "Requests" Forms class RequestForm(forms.ModelForm): new_thematic = forms.CharField( max_length=255, required=False, label="New Thematic" ) new_context = forms.CharField( max_length=255, required=False, label="New Context" ) due_date = forms.DateField( widget=forms.DateInput(attrs={"type": "date"}), required=False, ) class Meta: model = Demande fields = "__all__" widgets = { "thematic": forms.Select(attrs={"class": "form-control"}), "context": forms.Select(attrs={"class": "form-control"}), "technical_element": forms.TextInput(attrs={"class": "form-control"}), "due_date": forms.DateInput( attrs={"class": "form-control", "type": "date"} ), } def __init__(self, *args, **kwargs): super(DemandeForm, self).__init__(*args, **kwargs) if "instance" in kwargs: instance = kwargs["instance"] if instance.due_date: self.fields["due_date"].initial = instance.due_date self.fields["thematic"].queryset = Thematic.objects.all() …
