Setting up a webhook for a telegram bot in django
I want to make a simple telegram bot on Django, I have seen some tutorials on how to make a bot using plain python but I need to make it on Django I followed this tutorial and tried to adapt it to a Django project https://www.youtube.com/watch?v=vZtm1wuA2yc this is my views.py from typing import Final from django.http import HttpResponse from django.views.decorators.csrf import csrf_exempt from telegram import Update from telegram.ext import CommandHandler, MessageHandler, filters, ContextTypes, Application API_KEY: Final = 'myapikey' BOT_USERNAME: Final = 'myusername' # Comands async def start_command(update: Update, context: ContextTypes.DEFAULT_TYPE): await update.message.reply_text("Hello!

django ORM - subqueries with Max
I'm having some issues when trying to use the Django ORM with subqueries and the Max function (db: PostgreSQL 15) On the following model: class Task(models.Model): declaration = models.ForeignKey( Declaration, null=True, default=None, on_delete=models.CASCADE, related_name="tasks", ) sequence = models.PositiveIntegerField(blank=True, null=True) # # other fields I'm trying to filter tasks related to a declaration with the highest sequence. here's my attempt: sequences = Task.objects.filter(declaration=OuterRef("declaration")).exclude(sequence__isnull=True).order_by("sequence").distinct().values("sequence") max_sequences = sequences.annotate(max_seq=Max("sequence")).values("max_seq") qs = Task.objects.filter(sequence=Subquery(max_sequences)) however iterating the qs throws this error: ProgrammingError: more than one row returned by a subquery used as an expression inspecting the SQL, looks like this: SELECT "task"."id", "task"."declaration_id", "task"."sequence" FROM "task" WHERE "task"."sequence" = ( SELECT "subquery"."max_seq" FROM (SELECT DISTINCT MAX(U0."sequence") AS "max_seq", U0."sequence" FROM "task" U0 WHERE (U0."declaration_id" = ("task"."declaration_id") AND NOT (U0."sequence" IS NULL)) GROUP BY U0."sequence" ORDER BY U0."sequence" ASC) subquery) and the execution gives back the same error. Adding LIMIT 1 to the first subquery solves it on the db shell: SELECT "task"."id", "task"."declaration_id", "task"."sequence" FROM "task" WHERE "task"."sequence" = ( SELECT "subquery"."max_seq" FROM (SELECT DISTINCT MAX(U0."sequence") AS "max_seq", U0."sequence" FROM "task" U0 WHERE (U0."declaration_id" = ("task"."declaration_id") AND NOT (U0."sequence" IS NULL)) GROUP BY U0."sequence" ORDER BY U0."sequence" ASC LIMIT 1) subquery)` but I don't know how … -
Common User management for Django project ecosystem
I have been working with Django for the last few months and have built some projects in it. I was wondering whether it is possible for the distinct Django projects to share a common-use authentication and authorization project? There is a user management portal for the internal employees where the admin can add various employees to different user roles (like a manager, etc.). I will then define in the other projects what user role can access what part of the application statically. Additional parameters: There will be read-and-write operations on the user from all the projects There will be user-specific data (not user role specific user specific) Until now I have looked at the Django multi-database support which can solve my user authentication problem, but there is a catch in the authorization part where the foreign key constraints cause some problems in the models Currently, I have written a database router and am creating a user management portal for the authentication of users from a single source. -
Chained select inputs using Django CBV
I am trying to create an interface for a teacher to set homework tasks. This homework includes a student, a chapter, and questions belonging to a selected chapter. Therein lies my problem, I would like for my chapter dropdown to limit the selection from my question dropdown. Here is the current model, I added a chapter to simplify this process however ideally the chapter is not a necessary part of the homework, it only serves as a filter for the questions. class Homework(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) chapter = models.ForeignKey( Chapter, on_delete=models.SET_NULL, null=True, related_name="chapter_homework" ) question = models.ForeignKey( Question, on_delete=models.CASCADE, related_name="homework" ) agenda = models.ForeignKey( Agenda, on_delete=models.CASCADE, related_name="homeworks" ) This is the CreationView I have modified : class HomeworkCreationView(CreateView): template_name = "agenda/homework_create.html" form_class = HomeworkForm success_url = reverse_lazy("agenda:create_homework") def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['chapters'] = Chapter.objects.filterByAuthor(self.request.user) return context def get_form_kwargs(self): kwargs = super().get_form_kwargs() kwargs["user"] = self.request.user return kwargs And this is a function based view which is meant to asynchronously update the question choices : def loadQuestions(request): chapter_id = request.GET.get('chapter') questions = Question.objects.filterByChapterID(chapter_id).order_by('title') return render(request, 'agenda/question_dropdown_list_options.html', {'questions':questions}) Here is the form : class HomeworkForm(forms.ModelForm): def __init__(self, *args, **kwargs): user = kwargs.pop("user", None) super().__init__(*args, **kwargs) teacher = user.userToTeacher() self.fields["chapter"].queryset … -

Django custom .mo filenames not working for translations?
I have been playing with django app translation for a while now. But as my main app is becoming more complex, I've seen that some of the strings are not anymore detected by "makemessages", probaly as they originate from lists, and are only translated in the template through a {% trans my_list_item %} tag That means that each time I'm making a makemessages, those msgids are not detected, so the django.po file is updated, and my "undetected translations" are commented out. Ok, I can live with it. My next move is to create a separate po file undetected_messages.po where I stick all the translations which remain undetected. But the translations are not happening ... even if the corresponding undetected_messages.mo file seems to be created ok, and seems to contain the right info. When I put the undetected translation in the django.po file, everthing seems to happen as expected. But not when they are in a different po file with custom namefile. Any idea why? Any idea how I could solve the issue? Subsidiary question: Any idea how I could keep the translations linked to the "admin" module of each app in a separate file ... to avoid having those translations … -

Deploying django to vercel not working due to routing issues
I have a django project I am trying to host on vercel. When I configure my vercel.json as such, { "builds": [ { "src": "drinksData/wsgi.py", "use": "@vercel/python" } ], "routes": [ { "src": "/(.*)", "dest": "drinksData/wsgi.py" } ] } The application works, like the templates load but then if I try to access any of the JSON response views and treat it like an API, I get a CORS issue. So trying to follow the docs I then change it to this: { "builds": [ { "src": "drinksData/wsgi.py", "use": "@vercel/python" } ], "routes": [ { "src": "/(.*)", "dest": "drinksData/wsgi.py" } ], "headers": [ { "source": "/(.*)", "headers": [ { "key": "Access-Control-Allow-Credentials", "value": "true" }, { "key": "Access-Control-Allow-Origin", "value": "*" }, { "key": "Access-Control-Allow-Methods", "value": "GET,OPTIONS,PATCH,DELETE,POST,PUT" }, { "key": "Access-Control-Allow-Headers", "value": "X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5, Content-Type, Date, X-Api-Version" } ] } ] } But then I get a deployment issue about routes and headers clashing. So then I try using rewrites: { "builds": [ { "src": "drinksData/wsgi.py", "use": "@vercel/python" } ] ,"rewrites" : [{ "source": "/(.*)", "destination": "drinksData/wsgi.py" }], "headers": [ { "source": "/(.*)", "headers": [ { "key": "Access-Control-Allow-Credentials", "value": "true" }, { "key": "Access-Control-Allow-Origin", "value": "*" }, { … -
Django: Optimization using forms .has_changed in save method
I just noticed that django forms has a method .has_changed() and I'm just wondering if it would be a good idea for optimization to use it by overriding the save method and checking if form has changed before hitting the db? By doing this we would actually skip one unnecessary call to the db. What do you guys think about it? Would look something like this: def save(self, commit=False): property = super(PropertyPriceForm, self).save(commit=False) if self.is_valid(): ... if commit and self.has_changed(): property.save() return property -
When to use DRF Serializer's methods .save(), .create() and .to_internal_value?
On DRF documentation we have that: .to_internal_value() - For write operations. .create() - For saving instances. .save() - To persists the validated data into an object instance. It seems that we can do the same stuff with any of these. So what is the best practice to use them? -
Why are my images not loading in Django? - "GET /static/app/piechart.jpg HTTP/1.1" 404 1807
I cannot seem to load in an image in a website I'm creating in Django. I get the error "GET /static/app/piechart.jpg HTTP/1.1" 404 1807 in terminal whenever I load my site. My page's css stylesheet loads in without problems but the image does not load. These are the important snippets of code from my project files. I would assume that the error lies somewhere here. settings.py STATIC_URL = '/static/' STATIC_ROOT = "/Users/NAME_RETRACTED/Projects/stockOpt/app/static" STATICFILES_DIRS = [ BASE_DIR / "static", "/app/static", ] urls.py from django.contrib import admin from django.urls import path, include from django.conf import settings from django.conf.urls.static import static from app import views urlpatterns = [ path('admin/', admin.site.urls), path("", include("app.urls")), path('', views.index, name='views') ] .html files stylesheet link <link rel="stylesheet" type="text/css" href=" {% static 'app/styles.css' %} "> image tag <img src=" {% static 'app/piechart.jpg' %} " alt=" Image didn't load"/> This is what my file structure looks like. The image is in app/static/app/piechart.jpg. Now I assume that the problem either lies in how I referenced the static files in the .html files since when I command+click (follow link) on both references, it says "The editor could not be opened because the file was not found." OR it's something to do with … -
Format data queryset result to use in form.ModelChoiceField queryset option
I have a project in Django, where i have data in a postgres database. I want to create a form with a ModelChoiceField where i can select the data obteined in a previous queryset.

Django queryset icontains filter but "vise versa"
I have a Model: class Sources(models.Model): ... vendor = models.CharField(max_value=128, blank=True, null=True) ... And for example some data: select id, vendor from "webgui_sources"; id | vendor ----+----------------- 6 | oracle 5 | microsoft Then I have a string like "oracle;microsoft;apache" and I need to check are there models where vendor value is included to this string. So basically I need to collect all vendors which vendor value is included to "oracle;microsoft;apache". Whereas Sources.objects.filter(vendor__icontains='oracle;microsoft;apache') produces the following SQL-query: SELECT * FROM "webgui_sources" WHERE UPPER("webgui_sources".vendor) LIKE UPPER('oracle;microsoft;apache') I need to swap the fields and get something like this: SELECT * FROM "webgui_sources" WHERE UPPER('oracle;microsoft;apache') LIKE UPPER("webgui_sources".vendor) I tried to use extra and it did the job, but since using extra is not advised I tried to create custom lookup: class IContainsReverse(PatternLookup): lookup_name = "icontains_reverse" def as_sql(self, compiler, connection): lhs_sql, params = self.process_lhs(compiler, connection) params.extend([self.rhs]) return "%s ~* {}".format(lhs_sql), params Field.register_lookup(IContainsReverse) This lookup allows me to produce a query like this: Sources.objects.filter(vendor__icontains_reverse='oracle;microsoft;apache') select * from "webgui_sources" where 'oracle;microsoft;apache' ~* "webgui_sources".vendor; More or less it works but it looks clunky and works only with PostgreSQL. I hope that there is a more Django-way solution to do that, could somebody advice any more Django-way alternatives? … -

When I do this I am getting the following error message File "C:\Users\mikec\OneDrive\Documents\Conted\Web Applications with Python JavaScript and SQL\Sophie Canniffe Costume Design\myproject\myproject\urls.py", line 19, in from SCcontact import contact_view ImportError: cannot import name 'contact_view' from 'SCcontact' (C:\Users\mikec\OneDrive\Documents\Conted\Web Applications with Python JavaScript and SQL\Sophie Canniffe Costume Design\myproject\SCcontact_init_.py) I have a views.py form in my app (SCcontacts) as follows: from django.shortcuts import render from django.core.mail import send_mail from django.http import HttpResponseRedirect from django.urls import reverse def contact_view(request): if request.method == 'POST': name = request.POST.get('name') email = request.POST.get('email') message = request.POST.get('message') # Send email to the user user_subject = "Thank you for your enquiry" user_message = f"Dear {name},\n\nThank you for contacting us.

Django import ignores sys.path
A unit test module stored in /tmp is imported in my Django project. The unit test module begins like this: import tempfile import sys sys.path.insert(0, tempfile.gettempdir()) # /tmp is first in sys.path from name_like_app import foo # foo is the function to test # name_like_app.py is in /tmp # The import looks in the app instead of /tmp! The module containing foo is stored in /tmp, but happens to be named like one of the apps in my Django project. For some reason, Django looks in the app and ignores sys.path. Why does this happen?
