Add class to model form label Django
I've done a lot of digging on how to accomplish this, and aside from using 3'rd party modules is there not a simple way to customize labels for auto-generated forms in Django? i.e. models.py from django.db import models class Foo(models.Model): email = models.CharField(max_length=200) forms.py from django.forms import ModelForm from FooApp.models import Foo class FooForm(ModelForm): class Meta: model = Foo index.html <form action={% url 'FooApp:results' %} method="post" enctype="multipart/form-data"> {% csrf_token %} {{ form }} <button type="submit">Submit</button> </form> views.py from .forms import FooForm def index(request): form = FooForm() return render(request, 'foos/index.html', {'form': form}) This seems to be the most "Django" way of doing things, but it offers little flexibility in terms of using frameworks such as bootstrap (which requires classes to be added to specific elements including input labels) I have read many answers that use widget customization, for example if I wanted to add the class bar to my email field on my FooForm: forms.py from django.forms import ModelForm from FooApp.models import Foo class FooForm(ModelForm): class Meta: model = Foo widgets = { 'email': TextInput(attrs={ 'class': 'bar' }), } however, I still can't figure out how to add a bar class to the label that is generated along with this input … -
Converting Naive Datetime object to user selected timezone in Django Template
I have Naive Datetime object stored in my Postgresql DB. I know the timezone used in the django project. Now, I have to convert these time objects into user selected timezone values in the template. Is there any way to make all the naive datetime objects to aware objects in the DB using proper migration? -
does django db_index=True index null value?
for example if i have a field name slug = models.CharField(null=True, db_index=True,max_length=50) and while saving data if left slug empty. will database index this saved null value? -
How to initialise a field in Django models using other fields in the model
I would like to call an API that will return the latitude and longitude from a postcode which is part of my Django Model class Nurse(models.Model): firstName = models.CharField(max_length=100, default="") lastName = models.CharField(max_length=100, default="") postCode = models.CharField(max_length=10, default="") area = models.CharField(max_length=100) phoneNumber = models.CharField(max_length=20) email = models.EmailField(max_length=100, null=True) latitude = models.FloatField(max_length=10, null=True) longitude = models.FloatField(max_length=10, null=True) So when a nurse object is created, I would like to call an api (postcode.io) which means I am able to get a latitude and longitude based on the postcode that saves these values to the data model. I need to have the latitude and longitude because I have use for it in a template where I need to access this information. Thanks! -
is there a function that return current path but in Django class
I need function that return part of url but inside ListView(where"XXXX") About project: its just a shopping list. I have 2 classes in models(ShoppingList and ShoppingItem). ShoppingItem looks like this: name = models.CharField(max_length=50, null=False) count = models.IntegerField(null=False) list = models.ForeignKey(ShoppingList, on_delete=models.CASCADE, related_name='shopping_items')** date_created = models.DateTimeField(auto_now_add=True) My ListView class: class ListDetailUpdateView(ListView): model = ShoppingItem template_name = 'xlist_app/ListDetailUpdateView.html' context_object_name = 'products' queryset = ShoppingItem.objects.filter(list = XXXX) My idea is to cut last part of url (for example when i enter list number 2 i have adress http://127.0.0.1:8000/ListDetails/2) and replace "XXXX" with such a function. In my mind it should look like: queryset = ShoppingItem.objects.filter(list = int(request.path.split('/')[-1]) (if there is a better way to do that i will aprreciate all sugestions) -
Django update number of items on each save or delete
I am new to Django and still learning. I am looking to keep track of how many events I have under a test. My current model looks like class Test(models.Model): name = models.CharField(max_length=255) description = models.CharField(max_length=255, blank=True) num_of_events = models.IntegerField(default=0) class Meta: verbose_name = 'Test' verbose_name_plural = 'Tests' def __str__(self): return self.name class Event(models.Model): name = models.CharField(max_length=255) test = models.ForeignKey(Test,on_delete=models.CASCADE) class Meta: verbose_name = 'Event' verbose_name_plural = 'Events' def __str__(self): return self.name def save(self): obj, created = Test.objects.update_or_create(name=self.test) obj.num_of_events += 1 super().save() def delete(self): self.test.num_of_events -= 1 super().delete() I thought I could just override the save() function but it does not update on the admin panel and still shows 0. I am trying to figure out what I am doing wrong. -
Django message variable not available in If.. statement
I am trying to use the Django message system to send the user back to their previous page. I have a Delete Customer FBV that can be accessed from multiple locations and after deleting the customer I want to send the user back to where they were. If I do this it works well and I get the behavior I expected: @login_required def delete_customer(request, custpk): del_cust = Customer.objects.get(pk=custpk) returnURL = '' if request.method == "POST": storage = get_messages(request) for message in storage: returnURL = message.message storage.used = True del_cust.delete() return redirect(returnURL) context = { 'del_cust': del_cust } return render(request, 'delete_customer.html', context) However, I want to be able to use that returnURL variable both in the If "POST" section and in the context variable to send to the render statement. Why when I do this does it not work? @login_required def delete_customer(request, custpk): del_cust = Customer.objects.get(pk=custpk) returnURL = '' storage = get_messages(request) for message in storage: returnURL = message.message storage.used = True if request.method == "POST": del_cust.delete() return redirect(returnURL) context = { 'del_cust': del_cust, 'returnURL': returnURL } return render(request, 'delete_customer.html', context) Why does this not work? When the redirect hits it says there is nothing to redirect to. How can I … -

slug field to an existing database and unique slug generator
I already had a database created without the slug field. I wanted to add a unique slug field into my database. I have read the document django document on non nullable unqiue slug and have gone through the video: Master code online.

Why are my users messages not appearing fully?
Ok, so I am building an inbox and messaging system for my DatingApp. I have been able to display the conversations between my user and other users in my view 'Messages'. Now, I am attempting to display the contents of the conversations through messages via the Message view but I am failing. Because only the sent messages from request.user are showing. I attempted doing two queries at once through my InstantMessage model (which has a foreign key to my Conversation model), a query for request.user and one for user, but still, only the messages sent from request.user are showing up. And furthermore, when you click on the conversation, it should only show messages between that specific user but I am showing ALL messages sent out by request.user to ALL users. So I got two problems here. I'm super stuck on this, so any help would be HIGHLY appreciated. views.py/Message and Messages #Displays contents of a conversation via messages def message(request, profile_id): messages = InstantMessage.objects.filter(Q(sender_id=request.user) | Q(sender_id=profile_id)).\ values('sender_id','receiver_id', 'message', 'date', ).\ order_by('date',) conversations = Conversation.objects.filter(members=request.user) context = {'messages' : messages, 'conversations':conversations} return render(request, 'dating_app/message.html', context) #Displays conversations a user is having def messages(request,profile_id): messages = InstantMessage.objects.filter(Q(sender_id=request.user) | Q(sender_id=profile_id)).\ values('sender_id','receiver_id', 'message', 'date', … -
How can i get error logs on my live Django/Django channels app?
I deployed a Django/Django Channels application to a VPS using Nginx, Gunicorn, Daphne and systemd, everything seems to work for now, but when i try to reach a Websocket consumer of my app using this: ws = create_connection("ws://mydomain/receiver") ws.send('Test') I get a Connection refused error, which means that something is not right on my Django Channels side. Since the Django app is running on a linux VPS, i do not have access to a console like i would during development. Is there any way to check the errors of my application, or a console or anything that would help me see what's happening behind the scenes here? -
Django model that stores multiple other models that store multiple other models

Django Rest Framework - ImproperlyConfigured: Could not resolve URL for hyperlinked relationship
Similar to this question, but I do not have namespaces or base-names, so none of the solutions in that question have worked.

Django xhtml2pdf non-editable, read-only pdf?
I've got xhtml2pdf version 0.2.3 working in Django, to output a certificate for a user once a course has been completed. The only issue with it is that the PDF is editable, which means the user could change information on it (name, course name, date, etc.) before printing it out. I couldn't find anything in the docs or my searches that referenced whether or not you can make the PDFs read-only once generated. The view: import io from io import BytesIO from xhtml2pdf import pisa from django.core.files import File from django.template.loader import get_template def generate_course_certificate(earned_credit): template = get_template("reports/course_certificate.html") context = {"earned_credit": earned_credit} html = template.render(context) output = BytesIO() inmemoryfile = io.BytesIO(output.getvalue()) pdf = pisa.pisaDocument(BytesIO(html.encode("UTF-8")), inmemoryfile) earned_credit.proof_of_completion.save( f"{earned_credit.course.name} {earned_credit.pk}.pdf", File(inmemoryfile) ) earned_credit.save() I found it odd that it was editable by default. Is there a way to make it read-only? -
Error message : No DjangoTemplates backend is configured
I'm a pretty old guy who used a little bit Django 5-6 years ago. A friend helped me to develop a small program for my needs and I was very impressed by the flexibility of the tool. After 1 year, no more needs, so I stopped using it. Today, coming back to Django, I spend a day to understand how to reinstall Python and Django on Windows 10 and I tested Django with different old codes I used for learning. I still have the files (code, template, input, and output) but I get an error message. I suppose that this message can come from a change in the syntax (new version ??) or an incomplete installation. For a specialist, it would be maybe easy to solve the problem but for me, it is like to climb Everest. So, if anybody has an idea, I would appreciate a lot. To help, I prepare some information. 1/ - _ code _ errors messages (at running) _ template _ input _ output (I got before) 2/ - _ Installation of Python and Django (commands I used) Thanks a lot for your help ! 1/.....==== ==== code (file : main.py) ==== from django.conf import … -

Sidebar content list is coming below profile image in django webpage bootstrap 4
Everything was right until I used profile pic in webpage. The sidebar content which was on the right of webpage is now coming below profile pic. If I use float-right it comes to the right but still below profile pic. I'm using sublime 3 for this django project.

What is the purpose of app_name in urls.py in Django?
When include()ing urlconf from the Django app to the project's urls.py, some kind of app's name (or namespace) should be specified as: app_namespace in include((pattern_list, app_namespace), namespace=None) in main urls.py or app_name variable in app's urls.py. Since, I guess, Django 2, the second method is the preferred one Although I copy-pasted first function signature from Django 3 documentation. But that's not the main point. My current understanding of namespace parameter of include() is that it's what I use when using reverse(). What is the purpose of app_name in app's urls.py or app_namespace in main urls.py? Are these exactly the same thing? How is it used by Django? Existing questions (and answers) I've found here explain HOW I should specify it rather than WHY. -
