How to make a web app running on a local server secure?
I wish to create an app using Django, which users can use on their respective local networks. I want to make this secure, and I have trouble finding a way. Most answers point to using self-signed certificates on the server followed by installing certificates on each individual device on the network. However, this might be complicated and too much effort for the users, who may not be so tech savvy. Is there a simpler, cleaner way of making this app secure within the local network? Something I can automate as well. -

Issue with Loading HTML Template After Sending Email in Django
I'm working on a Django project where I need to send an email after a form submission. I have implemented the email sending functionality using the smtplib module. The email is sent successfully, but after that, I'm unable to load the corresponding HTML template (delivery_email_success.html). Here's the relevant code in my view: def enviar_email(request): if request.method == 'POST': # Process data and prepare the email try: # Email setup and sending # ... server.quit() except smtplib.SMTPException as e: return render(request, 's3_error.html') print('Now rendering the success') return render(request, 'delivery_email_success.html') else: return HttpResponse(status=405) And here's the HTML part that submits the form and calls this function: const emailForm = document.getElementById('email-form'); emailForm.addEventListener('submit', (event) => { event.preventDefault(); const visibleRows = document.querySelectorAll('.result-row'); const data = []; visibleRows.forEach(row => { const rowData = { title: row.querySelector('td:nth-child(2)').textContent, catalog: row.querySelector('td:nth-child(3)').textContent, folder: row.querySelector('td:nth-child(4)').textContent, assets: row.querySelector('td:nth-child(5)').textContent, package: row.querySelector('td:nth-child(6)').textContent, sk: row.querySelector('td:nth-child(7)').textContent }; data.push(rowData); }); const emailBody = tinymce.activeEditor.getContent({ format: 'html' }); const formData = new FormData(); formData.append('email_body', emailBody); formData.append('data', JSON.stringify(data)); const csrfToken = document.querySelector('input[name="csrfmiddlewaretoken"]').value; formData.append('csrfmiddlewaretoken', csrfToken); fetch("{% url 'email_delivery' %}", { method: 'POST', body: formData }) .then(response => response.json()) .then(result => { // Manejar la respuesta del servidor }) .catch(error => { // Manejar errores }); }); I have verified that … -
How to pass Ajax POST request with GeoJSON or simply JSON data in Django view?
I am learning how to use jQuery Ajax and how to combine it with my Django project. My Django template comes with a JS source that adds a Leaflet EasyButton to my map with an Ajax POST request to pass some JSON data that is then processed on the Django side: // Create a button to process Geoman features var btn_process_geoman_layers = L.easyButton('<img src="' + placeholder + '" height="24px" width="24px"/>', function (btn, map) { var csrftoken = jQuery("[name=csrfmiddlewaretoken]").val(); function csrfSafeMethod(method) { return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); } $.ajaxSetup({ beforeSend: function (xhr, settings) { if (!csrfSafeMethod(settings.type) && !this.crossDomain) { xhr.setRequestHeader("X-CSRFToken", csrftoken); } } }); // Retrieve all Geoman layers var geoman_layers = map.pm.getGeomanLayers(true).toGeoJSON(); // Process only layers that are feature collections if (geoman_layers["type"] === "FeatureCollection") { // For every feature (e.g. marker, polyline, polygon, circle) for (feature_idx in geoman_layers["features"]) { var feature = geoman_layers["features"][feature_idx]; // pass the feature using Ajax to Django switch(feature["geometry"]["type"]) { case "Polygon": console.log("Polygon"); $.ajax({ url: "", data: { "feature": feature }, datatype: "json", type: "POST", success: function (res, status) { //alert(res); alert(status); }, error: function (res) { alert(res.status); } }); break; default: console.log("Other feature: " + feature["geometry"]["type"]); break; } } } }); btn_process_geoman_layers.addTo(map).setPosition("bottomright"); Currently the data is all features of … -
Django - Includes with blocks inside?
How would you go about creating an include which takes HTML such as templates with blocks? The idea being to pass some blocks into a reusable component e.g. {% include 'banner.html' %} {% block text %} Christmas Sale! {% endblock %} {% block bodyCopy %} When checking out apply the <underline>discount</underline> code <span>F5000</span>! {% endblock %} {% end include %} This would allow you included component to take these different blocks and render as expected e.g. <header> <h1>{% block text $}</h1> <div> <p> {% block bodyCopy %} </p> </div> </header> Symfony has a similar concept called "embeds" -> https://twig.symfony.com/doc/2.x/tags/embed.html -

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.

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") -

I am trying to change {{password}} to a new {{password}} each time submit is pressed. from flask import Blueprint,render_template, request, g from gen import main #This is where the different website pages will be implemented with python views = Blueprint(__name__,'views') @views.route('/') def home(): return render_template('home.html') @views.route('/index.html') def generator(): return render_template('index.html', password = '') @views.route("/result", methods=['POST', 'GET']) def result(): password = '' return render_template("result.html",password = password + main()) def main(): pword ='' while True: x = randint(randint(20,30),randint(30,40)) randoml = [] while len(password) < x: lettersL = letters(alphabet) numbersL = numbers(alphabet) symbolsL = symbols(alphabet) randoml.append((random.choice(lettersL))) randoml.append((random.choice(numbersL))) randoml.append((random.choice(symbolsL))) if len(randoml) > 10000: password.append(random.choice(randoml)) pword = ''.join(password) return pword <html> <head>Generated Password</head> <body> <form class = "password" action = "/result" method = "POST"> <center> {% if password%} <h3 style="color: rgb(216, 44, 216)">Your password is {{password}}</h3> {% endif%} </center> </form> <form … -
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)
