File is not submitting correctly, nested objects Django Models
I am trying to create a method that will send a created Model object to the server, validate it and save it. But this Model has another Model nested in it. The Model that is nested in it has an image file that also needs to be validate, but everytime I submit it says that file is not a file and not the correct encoding type. Code async function createFile(input) { let response = await fetch(input); let data = await response.blob(); let metadata = { type: 'image/jpg' }; // let name = input.substring(input.lastIndexOf('/')+1,input.length); return new File([data], input, metadata); } const updated_items = async () => { let a = props.items for (let i = 0; i < a.length; i++) { let img = await createFile(props.items[i].cover) let newimg = { "lastModified": img.lastModified, "lastModifiedDate" : img.lastModifiedDate, "name" : img.name, "size" :img.size, "type": img.type } a[i].cover = img } return a } const onAddClick = async () => { const formData = new FormData(); let items = await updated_items() // formData.append('about', about); // formData.append('name', cname); // formData.append('worn',date); // items.forEach(item => { // formData.append(`items[]`, JSON.stringify(item)); // }); for (let pair of formData.entries()) { console.log(pair[0]+ ', ' + pair[1]); } // console.log(items) const data = … -

Django : computationally/data intensive website
I come from the world of object programming (C++, python...) and am currently switching to web programming (django). The websites I went to build are computationally and data intensive (like complex spreadsheets with a lot of math involved). I have a hard time understanding what databases are used for in web programming and more generally understanding the architecture of web apps (or say computationally intensive websites). Here is my understanding : Databases are only doing the persistence (in a very organised way, very much like how objects are organised in memory), not for computations? If computation is required on the data (and the computation is server-side), the data is first queried by django from the DB then loaded into a python "object" data model, then the computation happens in plain python and sent to the client thanks to django's templates? Am I right? Additionally, I expect the data to be loaded at the beginning of a session. Architecturally speaking, were in django should the query of the DB and deserialisation of the data be achieved? -
Is this legitimate way of overriding the default user model
I am overriding django's default user model . I tried to link the userprofile with the CustomUser model and added a receiver which will automatically create instance of profile model when user is created based on their role from django.db import models from django.contrib.auth.models import AbstractUser from django.dispatch import receiver from django.utils.translation import gettext_lazy as _ from .managers import CustomUserManager from django.db.models.signals import post_save # Create your models here. class CustomUser(AbstractUser): username = None email = models.EmailField(_("email"),primary_key=True,unique=True,blank=False,null=False) phone_number = models.CharField(max_length=10,null=False,blank=False) ROLE_CHOICES = ( ('ADMIN', 'ADMIN'), ('STUDENT','STUDENT'), ('TEACHER', 'TEACHER'), ('PRINCIPAL', 'PRINCIPAL'), ) role = models.CharField(choices=ROLE_CHOICES, blank=True,default='ADMIN',max_length=10) REQUIRED_FIELDS = ['phone_number','first_name','last_name'] USERNAME_FIELD = "email" objects = CustomUserManager() def __str__(self): return self.email class StudentProfile(models.Model): user = models.OneToOneField(CustomUser,on_delete=models.CASCADE) id = models.AutoField(primary_key=True,unique=True) merit = models.CharField(max_length=6,blank=True,null=True) def __str__(self): return self.user.email class TeacherProfile(models.Model): user = models.OneToOneField(CustomUser,on_delete=models.CASCADE) id = models.AutoField(primary_key=True,unique=True) salary = models.CharField(max_length=6,blank=True,null=True) education = models.CharField(max_length=100,blank=True,null=True) def __str__(self): return self.user.email class PrincipalProfile(models.Model): user = models.OneToOneField(CustomUser,on_delete=models.CASCADE) id = models.AutoField(primary_key=True,unique=True) salary = models.CharField(max_length=6,blank=True,null=True) education = models.CharField(max_length=100,blank=True,null=True) years_of_experience = models.IntegerField(null=True, blank=True) def __str__(self): return self.user.email @receiver(post_save, sender=CustomUser) def create_user_profile(sender, instance, created, **kwargs): if created: if instance.role == 'PRINCIPAL': PrincipalProfile.objects.create(user=instance) elif instance.role == 'STUDENT': StudentProfile.objects.create(user=instance) elif instance.role == 'TEACHER': TeacherProfile.objects.create(user=instance) else: pass else: print("Profile not created") As a newcomer to coding, I've crafted … -
Handling Django Migrations Folder Persistence in Azure App Service
I'm deploying a Django application on an Azure web app. As I've learned, Azure App Service is ephemeral, meaning I can't rely on files being persistent. While I've found solutions online on how to manage media files using Azure Storage, I'm unsure about how to handle other Django-specific directories, particularly the migrations folder. It seems imperative for Django to have access to this folder to conduct migrations properly. Can anyone guide me on the best approach to handle Django here? Or maybe handle azure? I'm surprised by the lack of online resources discussing best practices for this specific scenario. -
django simple JWT getting user ID from view level

Is there any way to recover Streamfield data that was lost due to lack of migration?
As a Wagtail newbie, I pushed changes to StreamFields in my models (i.e., adding new block types) without creating Migrations, as specified in the docs. This resulted in a large loss of user data, and unfortunately there isn't a recent database backup. If I were to go digging in a copy of the current Postgres database, would I be able to find the lost user data in the version history somehow? I'm also open to any other suggestions about how to recover the lost data, if possible. -
Django Crispy Form Doesn't Include Model ID When Using `{% crispy form %}` Tag
I have a Django crispy form that I'm using to update an object. I need to use a helper as follows: # forms.py from django import forms from crispy_forms.helper import FormHelper from crispy_forms.layout import Div, ButtonHolder, Submit class QuestionForm(forms.ModelForm): class Meta: model = Question fields = ('type', 'instructions', 'required') def __init__(self, *args, **kwargs): self.helper = FormHelper() self.helper.form_tag = False self.helper.layout = Layout( Div( Div(*self.fields.keys(), css_class='form-group'), ButtonHolder( Submit('submit', 'Submit', css_class='btn-primary') ) ) ) And in my template I have the following: <form method='post' action=''> {% crispy form %} </form> My problem is that in the rendered HTML, there is no hidden field storing the ID of the Question being updated. What I expect to see is something like this: <input type="hidden" name="question-id" value="1" id="id_question-id"> This is strange. So I tried doing the following: <form method='post' action=''> {{ form | crispy }} </form> And this works. The hidden ID field is present in my HTML, and everything works perfectly. Unfortunately, this approach does not work with my form helper, which defeats the purpose of using crispy-forms. Why doesn't the ID field show up when I use the {% crispy form %} tag? -

Django rendering {% csrf_token %} as string when I set innerHTML
I have a page in which I have created a modal. Now I'm creating form in the modal that can be generated dynamically on the basis of which button is clicked. I have this JS function that sets the model content with form data. function openModal(askField, platformName) { const modal = document.getElementById("modal"); const modalContent = modal.querySelector('.modal-content'); modalContent.innerHTML = ` <h2 class="m-2 text-xl font-semibold text-center">${platformName} Authorization</h2> <form class="p-2" method="post" action="/authorize/${platformName.toLowerCase()}"> {% csrf_token %} <div class="p-3 border border-gray-500 rounded-lg"> <div class="m-2 flex justify-start space-x-2"> <label class="font-bold" for="ask_field">${titleCase(askField.replace("_", " "))}</label> <input class="border" id="ask_field" name="ask_field" required> </div> <div class="flex justify-between"> <button class="px-4 rounded-lg text-white transition ease-in-out delay-150 bg-red-600 hover:-translate-y-1 hover:scale-110 hover:bg-indigo-500 duration-300" onclick="closeModal()"> Close </button> <button class="px-4 rounded-lg text-white transition ease-in-out delay-150 bg-blue-500 hover:-translate-y-1 hover:scale-110 hover:bg-indigo-500 duration-300"> Authorize </button> </div> </div> </form> `; modal.classList.remove('hidden'); } This modal works successfully. The only problem is that when this {% csrf_token %} is not actually embedded into the page but it's rendering as a string. I know as I'm adding this piece of HTML after the page is already rendered by the Django. That's why this is happening. Is there any way that I can get this working? -

String comparision returning False even if they are the same in python , inside a html file in DJANGO
so there is this IF statement inside a html file , which is failing to return a TRUE when both the strings are the same , i dont know why , i copy pasted the same strings from database to another python compiler and it said TRUE but it is only failing here I will add a sscreenshot of a reverse case where i will print it if they are not equal so you can see the string and confirm enter image description here this is the printed ones , i currently have 2 comments in my database enter image description here here it prints for both case ,hence shows how both strings are not same for both cases im using django one of the fields is a CharField with max length of 500 and another (post_id = models.CharField(max_length=500)) another is a uuid field (id = models.UUIDField(primary_key=True, default=uuid.uuid4)) i tried is instead of == , still fails im expecting it to only return a TRUE if both strings are equal ( please ignore the != in screenshot as it is just to print out the strings) -
How to annotate django queryest using subquery where that subquery returns list of ids from related model records
I have one database model, let's say ModelA: class ModelA(models.Model): field_1 = models.ManyToManyField( "core.ModelB", blank=True ) user = models.ForeignKey("core.User", on_delete=models.CASCADE) type = models.CharField(choices=ModelATypes.choices) The field_1 of ModelA is a many to many field that references ModelB. class ModelB(models.Model): uid = models.UUIDField(unique=True, default=uuid.uuid4, editable=False) amount = models.IntegerField() Now, I want to annotate the queryset to show the list of uid's from field_1 based on some filter like get the list of ModelB uid's from field_1 where user in ModelA is in list of applicable user ids. Example: from django.db.models import Subquery user_ids = [1, 2, 3] result = ModelA.objects.filter(type="year").annotate( model_b_uids_list=Subquery( ModelA.objects.filter(user__id__in=user_ids).values_list("field_1__uid", flat=True) ) ) This gives error more than one row returned by a subquery used as an expression. I tried using ArrayAgg function but that does not seems to be working. I want the annotated field model_b_uids_list on ModelA to have a list of uid's from the field_1 from multiple applicable records on ModelA. Can anyone help me understand what's going wrong here? -

React django file upload difference in content-length

How can I use only my custom models with social-auth-app-django?
How can I store people logged in or registered with social authentication only in the custom user model? By default, whenever I use social auths, they are registered in User social auths in PYTHON SOCIAL AUTH on the Admin page, but I would like to remove this duplication with the custom user model. This does not mean that I want those displays to disappear from the admin page, but rather that I want to optimize the database space. Libraries I use are DRF, socil-auth-django and Djoser. I want to keep only my custom user model. No other user model is needed. -
Is it possible to remove an item type from a lineitem.aggregate when making a different calculation?
The delivery cost should not include % on booking, but should include % of product price if below the set delivery threshold.

Cookies not being set in browser when making API request from React, but work with Django REST framework
When I use the Django REST framework to send a POST request to the login endpoint, the cookies are added to the response, and I can observe them in the browser. Additionally, I can confirm that I'm receiving the correct data (user ID and password) in both cases. However, when I use my React application to send the same POST request to the login endpoint, the cookies are not being added to the response, and consequently, they aren't stored in the browser. Again, I receive the correct data (user ID and password) in this scenario as well. My django rest code : @api_view(['POST']) def loginUser(request): print("request", request.data) id_Patient = int(request.data.get('id_Patient')) print("id_Patient", id_Patient) password = request.data.get('password') print("password", password) user = Patient.objects.filter(id_Patient=id_Patient).first() if user is None: print("user is None") return JsonResponse({"message": "User not found"}, status=404) if not user.check_password(password): print("not user.check_password(password)") return JsonResponse({"message": "Incorrect password"}, status=400) payload = { 'id_Patient': user.id_Patient, 'exp': datetime.datetime.utcnow() + datetime.timedelta(minutes=60), 'iat': datetime.datetime.utcnow() } secret_key = os.urandom(32).hex() token = jwt.encode(payload, secret_key, algorithm='HS256') response = JsonResponse({"token": token}) response.set_cookie('my_cookie', 'my_value', httponly=True) # Set the cookie return response What Actually Resulted: Surprisingly, the cookies are being set correctly when I test the API request using Django's REST framework, and I'm receiving the … -
