Django 'none' values from ajax
My views: def deleteDepartement(request): object_id = request.POST.get('Id') name= request.POST.get('name') print(object_id) print(name) try: D=Department.objects.get(id=object_id) except: print("NOT FOUND") return redirect('department') JavaScript code: $.ajax({ type: 'POST', url: "{% url 'deleteDepartement' %}", data: { csrfmiddlewaretoken: '{{ csrf_token }}', Id:objectId, name:'test', }, }); I got none in value in django views. When I console.log I got the id, but when i try to sent it i got none. Any suggestions please? -

How to skip over rows causing `Integrity Error` in unique constraints?
This is a model that I have and I want to modify it so One Advisor can only have one response with status Accepted, to do that I am creating a unique constrain in class Meta: class AdvisorResponse(UUIDTimeStampedModel): chat_request = models.ForeignKey(ChatRequest, on_delete=models.CASCADE, related_name='advisor_responses', null=True) advisor = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True) status = models.CharField(max_length=10, choices=ADVISOR_REQUEST_STATUS, default=ADVISOR_REQUEST_STATUS_ACCEPTED) # Data field holds calculated indexed data which is for UI consumption and doesn't change over time. data = JSONField(default=dict, blank=True) class Meta: constraints = [ models.UniqueConstraint( fields=['advisor', 'status'], name='unique_advisor_accepted_response', condition=models.Q(status=ADVISOR_REQUEST_STATUS_ACCEPTED) ) ] However, there are already existing database that has duplicate Status accepted for one response and that is causing Integrity Error: psycopg2.errors.UniqueViolation: could not create unique index "unique_advisor_accepted_response" DETAIL: Key (advisor_id, status)=(11, accepted) is duplicated I don't want to delete data in prod, how should I approach this migration so constraint on previous data is not applied like skipped over and only on new data being inserted. -

Add a set of 'sub-forms' (probably form set) to a ModelForm
I'm making some progress in solving this. What I want to model is this: I have a model for materials, a model for projects, and an intermediary model to specify more data to the many-to-many relationship between them. The objective is to allow a project not only to have multiple materials but also to specify a quantity for each. These are my models: class Material(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=200) description = models.CharField(max_length=3000, blank=True) unit = models.CharField(max_length=20) price = models.DecimalField(max_digits=9, decimal_places=2, validators=[MinValueValidator(0)]) created_by = models.ForeignKey(to=User, on_delete=models.CASCADE, related_name='materials') created_on = models.DateTimeField(auto_now_add=True) def __str__(self): return f'{self.name} (${self.price}/{self.unit})' class Project(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=200) description = models.CharField(max_length=3000, blank=True) materials = models.ManyToManyField(to=Material, through='ProjectMaterialSet', related_name='projects') created_by = models.ForeignKey(to=User, on_delete=models.CASCADE) created_on = models.DateTimeField(auto_now_add=True) def __str__(self): return f'{self.name}' class ProjectMaterialSet(models.Model): id = models.AutoField(primary_key=True) project = models.ForeignKey(to=Project, on_delete=models.CASCADE) material = models.ForeignKey(to=Material, on_delete=models.CASCADE) material_qty = models.PositiveIntegerField(default=1) Now, I have successfully rendered the project form containing a checkbox list of the materials (without the quantity feature), another form listing just one material as a checkbox, and a field for the quantity (a form of the ProjectMaterialSet model). Now, the part I'm struggling with is how to combine both. So far, I think what I need to do … -
Get access token from HttpOnly cookie for server side request with getServerSideProps
So, I've been working on a project using nextjs for frontend and django for backend. I'm also using HttpOnly cookies for my access and refresh tokens that I'm setting from my django backend. So, the thing is, if I send my requests on the client side by using useEffect for example, it works just fine. My django custom authenticate can read the cookie off of the request with no trouble. The problem is for when I use any server side function like getServerSideProps. I've checked and the problem is that the cookie isn't being sent with the request to the backend. I've tried to manually add the cookie to the request headers like this : export async function getServerSideProps(context) { const { req } = context console.log('accessToken >>> ', req.cookies.access); // Undefined const response = await axiosInstance.get('http://localhost:8000/api/project/projects', { headers: { "Authorization" : `Bearer ${req.cookies.access}` } }); const data = response.data; return { props: { data, }, }; } // axiosInstance export const axiosInstance = axios.create({ baseURL: "http://127.0.0.1:8000/api/", timeout: 20000, withCredentials: true, headers: { "Content-Type": "application/json", "Accept": "application/json" } }) But the problem is that the cookie I'm trying to read always gives back an undefined value.

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.

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

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

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? -
