post_save signal for specific Profile model for user registration
I have 2 profile models (Profile1 and Profile 2) with a one-to-one relationship with the django User class. I have 2 separate registration forms, 2 different signals, 2 different views / routes for each model. When I register a user with Profile1, it creates the Profile1 instance but it also creates a Profile2 instance. How can I specify the signal to use based on the type of user signing up?

Update field in unrelated table by spanning relationships using Django ORM
I am using Django 3.0.4. I have 6 tables (Vehicle, Tracker, Driver, Contract, Account and Invoice). There are Many Invoices for each Account(1-M). A single Account is opened for every single Contract(1-1). Each Contract is comprised of a Driver and a Vehicle and Driver-Vehicle combination can have only 1 Contract. Each Vehicle is fitted with a single Tracker(1-1). I intend to check the status of the Invoice(I have done this already) and navigating from this particular record of Invoice I need to find the particular Vehicle inorder to update the status of the Tracker. Tracker has no relation to Invoice and select_related does not seem to work.

How to display separate titles on each page in Django
I have a Django website where I have separated the html files into a base.html file as so: {% include 'head.html' %} <body> {% include 'nav.html' %} {% block content %} {% endblock content %} {% include 'footer.html' %} {% include 'scripts.html' %} </body> </html> Due to including head.html, the title on each page is the same, since head.html has only 1 title. Here is the head.html file: <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" href="{% static 'css/materialize.css' %}"> <link rel="stylesheet" href="{% static 'css/materialize.min.css' %}"> <link rel="stylesheet" href="{% static 'css/style.css' %}"> <link rel="stylesheet" href="{% static 'css/custom.css' %}"> <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet"> <title>mytitle</title> </head> But i want to display different titles for different pages and I dont know how to.

How to trim the length of a field's value to max_length in Django?
Suppose I have the following Django model: class City(models.Model): name = models.CharField(max_length=5, null=True, blank=False) When doing City(name='Sapporo').save(), is there a way to automatically trim the length of name to max_length such that "sappo" gets saved in database instead of throwing an error? I don't want to manually check the lengths and trim it myself since I have many charFields fields in many tables, all with different max lengths. -

How to count objects from database filtered by a choice field in django?
I have Porumbei model and it has gender field. In template I must render the number of Porumbei of each gender. For example: Male= x Porumbei, Female= y Porumbei and Unknown = z Porumbei. My model class Porumbei(models.Model): SEXE = [ ('Mascul', 'Mascul'), ('Femelă', 'Femelă'), ('Pui', 'Pui') ] ... gender = models.CharField(max_length=6, choices=SEXE, db_index=True) ... For Total I have: total = Porumbei.objects.count() Below is what I have now: @staticmethod def masculi(crescator=None): """ Numarul de masculi din sistem """ mascul = Porumbei.objects.filter(gender="Mascul", is_active=True, crescator=crescator) return len(mascul) @staticmethod def femele(crescator=None): """ Numarul de femele din sistem """ femela = Porumbei.objects.filter(gender="Femelă", is_active=True, crescator=crescator) return len(femela) @staticmethod def pui(crescator=None): """ Numarul de pui din sistem """ pui = Porumbei.objects.filter(gender="Pui", is_active=True, crescator=crescator) return len(pui) These functions gets me what I want but from my point of view, are not well optimized. This will end up in three similar queries as I saw in django debug toolbar. My question is, how can I get the number of each gender in only one query. Is it possible with another method or this function can be optimized to do a single query in database? I must mention that with the number of each gender, arithmetic operations must be … -
Group objects that share a field value in common in the same line in Django admin result list
I have a model Allocation in which several objects can share the same datetime field. In the admin page with the result list all objects are in a separate line but it makes the list difficult to read, so my question is what could be the solution to group these objects in a single line? I have no idea how to implement such customization and if there is filter to do that as I'm new to Django. I did a try with fieldsets but it modify the object page not the page with the result list. I'm afraid this is not that easy to implement but I wanted to ask. Thanks! class Allocation(models.Model): portfolio = models.ForeignKey( Portfolio, on_delete=models.CASCADE, related_name='allocation', null=True ) datetime = models.DateTimeField( null=True ) instrument = models.CharField( max_length=10, null=True ) This is what I have in the admin list result page: | Portfolio | Datetime | Instrument | ------------------------------------------------ port1 2020/01/01 AAPL port1 2020/01/01 MSF But what I would like is this: | Portfolio | Datetime | Instrument1 | Instrument2 | ------------------------------------------------------------------- port1 2020/01/01 AAPL MSF -
How jinja2 handles list index out of range error?
Think of a list, for example: a = [1,2,3], in python if you access a[4] you will get the 'list index out of range error'. Now, let's pass our list a to a jinja2 template engine and render following values: {{ a[0] }} -> 1 this is as expected {{ a[4] }} -> expected an error but the error is not raised !!! Anyone knows why jinja2 does not raise an error when rendering {{ a[4] }} and quietly pass this obvious error? I could not find anything related in the documentation: https://jinja.palletsprojects.com/en/2.11.x/ -
I couldn't play the audios that were uploaded to admin
I created a new class in my model.py file: class Audio(models.Model): ..... audio_object = models.FileField(default='') And I uploaded my audios to my admin page. However, the audios don't play and I right-clicked to a new browser, it shows "Page Not Found" saying "The current path, appname/“/media/nameoftheaudio.mp3”, didn't match any of the URLconf defined in projectname.urls. I reviewed the answers from Django MEDIA_URL and MEDIA_ROOT but it didn't solve my problems. In my urls.py, I already have: from django.conf import settings from django.conf.urls.static import static urlpatterns += staticfiles_urlpatterns() urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) And in my setting.py, I have: STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'assets'), ) MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') Another piece of information is the audios I uploaded to another class work fine! And that is the first class model I created in this project. I can't detect what do I lack for this Audio class. I am using Django 3.0.4 Thank you!! -
Django enclosing substring in string with anchor tags with href attribute
Right now im using regex to search for the substring in a given string then enclosing it in anchor tags with href that is in jinja template pattern = re.compile(rf"({substring})",re.IGNORECASE); anchoredString = mark_safe(re.sub(pattern, "<a href=\"{% url 'url' substring %}\">"+substring+"</a>"),string))) The tags work fine but when I click on the link, it tries to redirect me to the literal "{% url 'url' substring %}" not the "url" path that I defined in my urls.py. Is there a better way of doing this? -
Django/AJAX - New data is not getting rendered after first jQuery AJAX call (i.e. on subsequent calls)
I have tried to set the cache property to false on the AJAX request, but it did absolutely nothing. I am implementing a JS calendar and when you click on any day, it opens a popup overlay that also includes another calendar.

I'm pretty sure I have linked the static files in the right way since not doing so would not render my website as expected. I have tried doing the same changes to a separate copy not linked with django, and it worked. Anyone know whats going wrong? -
docker-compose up on Django in Docker container just prints "exited with code 0" rather than "Starting Development Server"

If anyone has any references for running and developing Django in Docker on Windows that'd be great I'm not having much luck getting this working. I don't even have a DB setup and it's … -
Modal to confirm delete
I have a form for creating products and editing existing products. I can submit changes just fine but when I added a delete button that opens a modal to confirm the delete I've run into some unexpected problems. template.html <div class="container-fluid"> <form enctype="multipart/form-data" method="POST"> {% csrf_token %} {{form|crispy}} {{form.errors}} <button type="submit" class="btn btn-primary btn-block"><i class="fa fa-upload"></i> Upload</button> {% if instance %} <button class="btn btn-danger btn-block" data-toggle="modal" data-target="#exampleModalCenter"><i class="fa fa-trash"></i> Delete</button> {% endif %} </form> </div> <div class="m-4"> {% for product in products %} <a href="{% url 'main:update_product_view' slug=product.slug %}"> <h2>{{product.product_title}}</h2> </a> {% endfor %} </div> {% if instance %} <div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true"> <div class="modal-dialog modal-dialog-centered" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLongTitle">Confirm Action</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> Are you sure you want to delete {{instance.product_title}}? </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> <a href="{% url 'main:delete_product_view' instance.slug %}"><button type="button" class="btn btn-danger"><i class="fa fa-trash"></i> Delete</button></a> </div> </div> </div> </div> {% endif %} views.py def create_product_view(request): if request.method == "POST": form = CreateProductForm(request.POST, request.FILES) if form.is_valid(): product = form.save(commit=False) product.save() return redirect('main:homepage_view') else: form = CreateProductForm context = { "title": "Create - Product", "form": form, } return render(request=request, …
