Django 4.2 : `receiver` Decorator Does Not Receive Signal
I am experimenting with Django Signals. In the documentation, it is written that there are two ways to connect a receiver to a signal. Using Signal.connect method Using receiver decorator Here's what I have implemented: # models.py from django.db import models from django.dispatch import receiver from .signals import demo_signal class Demo(models.Model): demo = models.CharField("demo", max_length=50) def send_signal(self): demo_signal.send(self) print('signal sent') def connect_receiver(self): demo_signal.connect(signal_handler, sender=self) @receiver(demo_signal, sender=Demo) def signal_handler(**kwargs): print('signal handled') # signals.py from django.dispatch import Signal demo_signal = Signal() However, when I call send_signal method, I don't get signal handled printed out unless I call connect_receiver method first. In [1]: demo = Demo.objects.get(pk=2) In [2]: demo Out[2]: <Demo: Demo object (2)> In [3]: demo.send_signal() signal sent In [4]: And Interestingly enough, after implementing pre_delete_handler as follows, without connecting, calling delete method does call pre_delete_handler @receiver(pre_delete, sender=Demo) def pre_delete_handler(instance, **kwargs): print(instance, kwargs) print('pre delete') Receiver does receive the signal without sender argument: @receiver(pre_delete) def pre_delete_handler(instance, **kwargs): print(instance, kwargs) print('pre delete') But how can I make it listen to a specific Model? Why does sending signal does not call its receiver(decorated signal_handler) in my case? -

Redis connection scheduled to be closed ASAP for overcoming of output buffer limits
I have some celery tasks that run on VMs to run some web crawling tasks. Python 3.6, Celery 4.2.1 with broker as Redis (self-managed). The same Redis server is used for caching and locks. There are two relevant tasks: 1. job_executor: This celery worker runs on a VM and listens to the queue crawl_job_{job_id}. This worker will execute the web crawling tasks. Only a single job_executor worker with concurrency = 1 runs on 1 VM. Each Crawl Job can have 1-20,000 URLs. Each Crawl Job can have anywhere between 1 to 100 VMs running in a GCP Managed Instance Group. The number of VMs to be run are defined in a configuration for each crawl job. Each task can take from 15 seconds to 120 minutes. 2. crawl_job_initiator: This celery worker runs on a separate VM and listens to the queue crawl_job_initiator_queue. One task creates the required MIG and the VMs using terraform for a single Crawl Job ID and adds the job_executor tasks to the crawl_job_{job_id} queue. The task takes about 70 seconds to complete. The concurrency for this worker was set to 1 so only 1 Crawl Job could be started at once. To reduce the time it … -

htmx not working on newly added form in django inline_formset
I have a form for my Purchase Order in which the items are presented in tabular format using django inline_formset. Within the form of the inline_formset, a search icon is placed beside the product select-form such that when the user will click on it, a modal will popup providing a functionality to the user to be able to search a product. And when the user will click a product on the search page, the corresponding product select-form in the main PO form will be updated/changed with the searched product. There is also an "Add more items" button which will add new form to the inline_formset, thereby providing a functionality to the user to dynamically add more PO items (using javascript). All the abovementioned features work fine except that in the newly added, the search icon failed to execute the hx-get embedded within the icon, like so: In pod_form.html, td> <div class="input-group"> {{ field }}{% if field.name == 'product' %} <i class="fa-solid fa-magnifying-glass ms-1 d-flex align-items-center fa-icon" hx-get="{% url 'product_search_popup' %}" hx-target="#dialog"></i> {% endif %} </div> <!-- dispaly field errors if there's any --> {% for error in field.errors %} <span style="color: red">{{ error }}</span> {% endfor %} </td> this html … -
Is this the right way to use python maigret module?
I am using "maigret" module in Django application to search usernames in social medias. Maigret can only be used through cli so i had to use subprocess to run and get the output. But is this the best way to do it? I couldn't find any other solution. Below is the function that i have created. def SearchNames(request): if request.method == 'POST': try: data = json.loads(request.body) name = data.get('name', '') network = data.get('network', '') output = subprocess.run('maigret {} --site {}'.format(name, network), shell=True, capture_output=True).stdout outputs = output.decode("utf-8").split("\n") matching = [s for s in outputs if "Search by username" in s][0] total_account_found = [int(s) for s in matching.split() if s.isdigit()][0] print({"accountsFound":total_account_found, "network":network}) return JsonResponse({"accountsFound":total_account_found, "network":network}, safe=False) except: return JsonResponse({'error': 'Error occurred while searching for username'}, status=400) return JsonResponse({'error': 'Invalid request'}, status=400) I wanted to know if there is better way to use maigret other than subprocess. -
Django - Pre-fetching ForeignKeys for M2M set
I see this thread which is the reverse (pre-fetching M2M set for foreignkey) - but how can I prefetch the ForeignKeys for a M2M set (as well pre-fetching the initial M2M set)? E.g. I have the following objects: Genre, Book, and Author. A Book can only have one Author. A Genre can have many Books (and vice versa) On my Genre Detail page, I would like to prefetch and list all the Books (M2M set) as well as prefetch all the Authors for each Book (ForeignKey). None of the following seem to work: Genre.objects.all().prefetch_related("book_set", "book_set__author") Genre.objects.all().prefetch_related("book_set").select_related("book_set__author") Genre.objects.all().prefetch_related("book_set").select_related("author") -
How can I make 'submit' in html delete a variable in python? (I am using Flask)

Calculate Pyton Enum each time when evaluated with datetime?
Is there a way to create an Enum in Python that calculates the value each time the Enum attribute is accessed? Specifically, I'm trying to create an Enum class that stores values like TODAY, TOMORROW, etc. for a web app (in Django) that runs for many days and I want the value recalculated each time it's accessed in case the day changes. So, say, the app is launched on March 1, if the app makes the check for TODAY on March 3, it will return March 3 and not March 1 which is what it would be initialized for. from enum import Enum import datetime class MyEnum(Enum): TODAY = datetime.datetime.now() TOMORROW = datetime.datetime.now() + datetime.timedelta(days=1) -
How to return back to original page after redirect?
I'm building a webpage that needs an age-gate. For this to work I'm using Django sessions. The view checks if the age-gate has been passed and otherwise redirects the user back to the age-gate. After A user passed the age-gate I want to redirect them back to the page they came from. How do I do this? I tried using request.META.get('HTTP_REFERER') but that did not work. My view looks like this: `def main_view(request): if request.session.has_key('agegate'): random_category = random.choice(Category.objects.all()) random_picture = random.choice(CoreImages.objects.all()) context = { 'image' : random_picture, 'category' : random_category, 'bottles': Bottle.objects.all(), } return render(request,'Academy/home.html', context) else: return redirect('/preview/agegate')` The age-gate view looks like this: def age_gate_view(request): next_url = request.META.get('HTTP_REFERER') form = AgeGateForm() if request.method == 'POST': form = AgeGateForm(request.POST or None) if form.is_valid(): form.save() request.session['agegate'] = 'welcome' return HttpResponseRedirect(next_url) context = { 'form':form, } return render(request,'Academy/agegate.html', context) -
ManyToManyField not saving correctly
I have an item_option this is a ManyToManyFiled that links to an ItemOption model. In the Django panel, I can insert ItemOptions, and they are saved correctly in the database, but product.item_option.all() returns an empty array. I found that the ItemOption is being inserted but nothing is being inserted in the ManyToManyTable database_product_item_option. Manually adding the indexes to this table fixes the problem, and I can successfully retrieve ItemOptions using product.item_option.all() How can I make Django do this automatically? I feel like I'm close to the solution but I haven't been able to find what's wrong with my code or what's missing. Here's my code: Product class Product(models.Model): id = models.AutoField(primary_key=True) ... item_option = models.ManyToManyField('ItemOption', blank=True, related_name='item_option') ItemOption class ItemOption(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) name = models.CharField(max_length=100, blank=True, null=True) price = models.DecimalField(max_digits=10, decimal_places=2) default = models.BooleanField(default=False) Form class ItemOptionForm(forms.ModelForm): class Meta: model = ItemOption fields = ['name', 'price', 'default'] class ItemOptionInline(admin.TabularInline): model = ItemOption form = ItemOptionForm extra = 1 can_delete = True class ProductAdmin(admin.ModelAdmin): list_display = ('title', 'price', 'product_type') list_filter = ('product_type', 'brand') exclude = ('item_option',) inlines = [ItemOptionInline] admin.site.register(Product, ProductAdmin) -

Password reset with Javascript and Django Rest Framework
I'm trying to use the Django Rest Framework library to reset the user's password. I followed some tutorials, mainly this one: https://pypi.org/project/django-rest-passwordreset/. However, none of the tutorials showed how to make the password reset independent of the frontend-to-backend address. The process described in all the tutorials I found follows a similar procedure. The user submits their email via the frontend to the backend, and then the backend sends an email to the user containing a link for password recovery. The problem, in my case, lies here. The backend needs to know the frontend's address, meaning the frontend's address needs to be hard-coded in the backend so that the link sent in the email directs to a page on the frontend. My question is: Is there any way for the backend to discover the frontend's address during the password recovery process? Alternatively, is there an easier way to implement password recovery? -

The goal is to generate an image file from the DataFrame within the Django management command. from decimal import Decimal import dataframe_image as dfi import pandas as pd def color_negative_red(val): color = 'red' if val < 0 else 'green' return 'color: %s' % color futures_risk_table_1={'PNL ITD': {'BTCUSDT': Decimal('-366.91850000'), 'ETHUSDT': Decimal('20.11800000'), 'TOTAL': Decimal('-241.39039746')}, 'FUNDING ITD': {'BTCUSDT': Decimal('285.87113447'), 'ETHUSDT': Decimal('11.23925312'), 'TOTAL': Decimal('230.66567605')}, 'DELTA VOLUME ITD': {'BTCUSDT': Decimal('11413146.44950000'), 'ETHUSDT': Decimal('3739417.96300000'), 'TOTAL': Decimal('16904364.71747007')}, 'HEDGE VOLUME ITD': {'BTCUSDT': Decimal('5858487.37460000'), 'ETHUSDT': Decimal('2208062.55358281'), 'TOTAL': Decimal('9812329.10964750')}, 'GROSS OI': {'BTCUSDT': 1142375.5, 'ETHUSDT': 34665.484173792, 'TOTAL': 1507336.3651526954}, 'DEFICIT': {'BTCUSDT': 4126.2, 'ETHUSDT': 6105.2643768768, 'TOTAL': 14643.812931051634}, 'PNL 4HR': {'BTCUSDT': Decimal('-110.42400000'), 'ETHUSDT': Decimal('-19.04450000'), 'TOTAL': Decimal('-58.85838895')}, 'FUNDING 4HR': {'BTCUSDT': Decimal('51.78039448'), 'ETHUSDT': Decimal('-0.15025893'), 'TOTAL': Decimal('35.63325078')}, 'DELTA VOLUME 4HR': {'BTCUSDT': Decimal('2554914.73350000'), 'ETHUSDT': Decimal('1032545.61450000'), 'TOTAL': Decimal('3892830.05291726')}, 'HEDGE VOLUME 4HR': {'BTCUSDT': Decimal('1393409.78960000'), 'ETHUSDT': Decimal('332477.41883101'), 'TOTAL': Decimal('2029616.07723308')}} futures_risk_table_1=pd.DataFrame.from_dict(futures_risk_table_1) print(type(futures_risk_table_1)) futures_risk_table_1_styler = futures_risk_table_1.style.applymap(color_negative_red).set_caption("Futures Risk Monitor").format("{:20,.0f}").set_properties( subset=pd.IndexSlice[futures_risk_table_1.index[-1], :], **{'background-color': 'lightblue'} ) futures_risk_table_1_styler dfi.export(futures_risk_table_1_styler,"files/images/futures_risk_table_1_styler.png") …
