How to embed a filter in the other side of a foreign key relationship in django
I have the following structure: class Room(models.Model): doors: BaseManager class Door(models.Model): deleted = models.BooleanField(default=False) room = models.ForeignKey(to=Room, related_name='doors' ) Now after I've saved a room and saved some doors which reference that room I can load a room and get all the doors in the room... However, when I do a room.doors.all() I actually want to receive only those doors that are not deleted (that have deleted as false). How would you do this with django? -

how to fix video displaying error in Django?
So basically I was following a tutorial (https://www.youtube.com/watch?v=aR_JzBGdGvM) on how to upload videos to django but I'm having trouble at the html because the video tag won't play the video, it'll only play the sound. Here is my code <div class="container"> {% for vid in videos %} <h3 class="text-center mt-2 mb-2">{{ vid.caption }}</h3> <video class="embed-responsive embed-responsive-4by3" controls="controls"> <source class="embed-responsive-item" src="{{ vid.video.url }}" type="video/mp4" /> </video> {% endfor %} </div> The for loop and everything is working its just that the video itself won't play. The audio will play but the video won't. I am on a mac if that makes any difference because the video file is a .MOV but even when I try bootstrap's way <div class="embed-responsive embed-responsive-16by9"> <iframe class="embed-responsive-item" src="{{ vid.video.url }}" allowfullscreen></iframe> </div> the video doesn't play it just downloads it. How can I fix this? Please Help! Thank You! -
DJANGO: how to use "core" URL in template
I'm trying to use a "core" url in my template but I don't know what is happening, It won't let me. My url is declared here: url.py: (the djangorestframework is the important one) urlpatterns = [ path('admin/', admin.site.urls), path('consumos/', include('consumptions.urls', namespace='consumptions')), path('registros/', include('logs.urls', namespace='logs')), path('reglas/', include('rules.urls', namespace='rules')), path('djangorestframework/', include(router.urls), name="drf"), path("", include("authentication.urls")), path("", include("dashboard.urls")), ] But when I'm trying to use it in my sidebar I have to sidebar.html: <li class="mt-3 nav-item"> <!-- FIXME: Esta url tiene que haber otra manera de llamarla --> <a target="_blank" class="nav-link" href="/djangorestframework"> <i class="fas fa-cloud"></i> <p> API </p> </a> </li> because it won't let me use it like this: <li class="mt-3 nav-item"> <!-- FIXME: Esta url tiene que haber otra manera de llamarla --> <a target="_blank" class="nav-link" href="{% url 'drf' %}"> <i class="fas fa-user-cog"></i> <p> API </p> </a> </li> It says: Reverse for 'drf' not found. 'drf' is not a valid view function or pattern name. Why I can not use the name of my url? why do I have to use a relative path? Thank you! -

Django does not filter by non english letters
In my database I have objects with slavic letters (śćę etc.). It is displayed correctly in my database, admin panel and even when I call my object in template. User can search for this object by providing what he wants in text input box: template.html <input type="text" class="form-control" placeholder="Model" name="searched_model" id="searched_model" value=""> Hovewer when I filter the objects database in my view: views.py found_products = ProductBase.objects.filter(Q(model__contains=searched_model).order_by('model') It filters and displays correctly until slavic letter is provided. For example, user wants object with model property as: ObjectŚĆobject If he writes in my search field object it will find and display ObjectŚĆobject. But if he writes objectŚ or even Ś only it will not show anything. My view returns found_products to template and displays it in table: template.html {% for item in found_products %} ... <td> {{item.model}} </td> I don't know where lies the problem. In settings.py I have correct LANGUAGE_CODE = 'pl-pl'. -
Access Multiple FIles Upload in Django

Calling an External API That Fails Randomly
I am using Django server to call a Korean government's weather API to retrieve weather data for around 1800 locations. However, this weather API results in time out most of the time. I tried giving resting periods. For example, for every request, it will sleep for 0.8 seconds and after every 30 requests, it will sleep for 30 seconds. But this does not really work well for 1800 requests. At one point, it was successful. All other times, it ended up with fail. In this kind of situation, what else should I do to make sure that 1800 requests are completed within one hour? Is there any way for this to restart the request sequence from the exact point it failed previously? For someone who is curious about what this code looks like, I am posting it below: class WeatherCreate(View): def get(self, request): today = date.today().strftime("%Y%m%d") today = str(today) current_time = datetime.now(pytz.timezone('Asia/Seoul')).strftime('%H') current_time = str(current_time) + "00" current_time = "1100" print(current_time) if current_time not in ("0200", "0500", "0800", "1100", "1400", "1700", "2000", "2300"): return JsonResponse(data={"message": "DATA IS NOT AVAILABLE AT THIS TIME.

How safe is a deployed Django app (with login only)?
I am about to deploy my first Django app. The plan is to push the locally running Docker container somehow to Google Cloud Run and now I wonder how safe my data will be then. I am aware of the Deployment checklist and I read the Security chapter in Django for Professionals. In my case, the whole app is accessible for logged in users only and, for the beginning, only a couple of trustworthy people will have an account. My assumption is, that – even if inside the app something should be not perfectly secure yet (let's say I forgot a csrf_token) – only logged in users could do any harm. Is this assumption too naive? So I have to make sure that everybody has a strong password and I should install some protection against fraudulent login by brute force password guessing, right? Is there anything else I have to consider? -

Problems while adding images with Django summenote
I succesfully added summernote to my admin site for a blog, however, when I add an image to a post directly via Image URL address it occupies the "Read more" button. (Picture related: Error when trying to render the page.) However this does not happen when uploading the picture directly from my computer. I'm sure it has something to do with the HTML autoescaping, but I relatively new at this and I dont know how to debug it. The HTML I used is the following: <div class="col-md-8 mt-3 left"> {% for post in post_list %} {% autoescape off %} <div class="card mb-4"> <div class="card-body"> <h2 class="card-title">{{ post.title }}</h2> <p class="card-text text-muted h6">{{ post.author }} | {{ post.created_on}} </p> <p class="card-text">{{post.content|slice:":200" }}</p> {% endautoescape %} <a href="{% url 'post_detail' post.slug %}" class="btn btn-primary">Read more &rarr;</a> </div> </div> {% endfor %} </div> -
Python-Django Trying to Add Users to my Database
I'm new to Django and I'm trying to create a page that allows users to register to my website. But I keep getting a page not found error. Using the URLconf defined in myapp.urls, Django tried these URL patterns, in this order: 1. admin/ 2. home [name='home'] 3. account/ register/ [name='register'] The current path, account/register/register, didn't match any of these. Here's the code inside my html file 'register.html': <form action = 'register' method = "POST"> {% csrf_token %} <input type='text' name='first_name' placeholder = "First Name"><br> <input type='text' name='last_name' placeholder = "Last Name"><br> <input type='text' name='username' placeholder = "Username"><br> <input type='password' name='password' placeholder = "Password"><br> <input type='Submit' placeholder='Submit'> </form> And here's the code inside 'myapp.views': from django.shortcuts import render, redirect from django.contrib.auth.models import User, auth def register(request): if request.method == 'POST': first = request.POST['first_name'] last = request.POST['last_name'] usern = request.POST['username'] passw = request.POST['password'] user = User.objects.create_user(first_name = first, last_name = last, username = usern, password = passw) user.save() return redirect('/home') else: return render(request, 'register.html') Why doesn't it create a new user in my database and redirect to '/home', and instead go to 'account/register/register'? Thanks in advance.
