I'm not an expert in Django, but I was reading here and found that there's not much I can do to compile SASS in production environment. Could you suggest some way to compile SASS/SCSS in production environment? Can node JS and python run simultaneously on VPS so that sass can be compiled? -
Need help in creating a beginner project
I really need some help, so I am learning Django and getting an opportunity in my current job to get a role as a backend developer. I am still at the beginner level. I know how to make basic projects and stuff but now my employer has asked me to make a project as follows- Create a User authentication model using JWT and REST Framework Then one admin and other users are to there. Using CURD I need to allow the users to add sales in the project with relevant fields. In the end the admin should be able to see all user profile sales and should be able to edit. While A user should just be allowed to edit or see his own sales. Can you please help me? I am not able to get a hold of how to implement JWT token and create the start of it. How will I be making the model. Because as much knowledge I have gained it's about creating a superuser creating a user form and then allowing them to add their profiles. But doing it via API in REST FRAMEWORK is somehting I need help on. -

how to insert raw html to django-cms page using cms.api?
I am using django-cms and their cms.api to migrate some articles from a WordPress site.

I have looked up all possible resources I could think of and nothing is working. -
Adding products to Shopify with MEDIA (3d models, images ....) using ShopifyAPI - DJANGO
Hope you're having a wonderful day! I'm working on an a Django project that uses ShopifyAPI using this project as base: https://github.com/Shopify/shopify_django_app, i was able to Authenticate, see and add products, My problem is that i couldn't add media to the products using the api (for example .glb files for 3d models) in order to preview it in the store website. I want to be able to create products and assign all information using my view. i create products like this: new_product = Product() new_product.title = title new_product.tags = ",".join(tags) new_product.product_type = product_type new_product.vendor = vendor price = self.request.data.get('price', '50.00') sku = self.request.data.get('sku', 'Default-SKU') variant = Variant() variant.price = price variant.sku = sku new_product.variants = [variant] new_product.save() I reasearch some solutions but i couldn't find any, except maybe for using metafields and that's how i tried it but with no use! metafield = Metafield({ "namespace": "digital", "key": "file_url", "value": file_url, "value_type": "string", "description": "Download link for the digital product", "owner_resource": "product", "owner_id": new_product.id }) metafield.save() how can i attach media to products from my django view? thanks in advance -
Enum values not enforced
In Django, I'm trying to create a enum-based database field. I'm avoiding external libraries and want to only use vanilla Django4. Essentially, I'm replicating the example given in Python - Covert enum to Django models.CharField choices tuple However, the enum values are not enforced. I can easily create a database entry with animal = 'foo' and it happily writes this into the database. I am expecting this to yield an IntegrityError, since I'm explicitly using an enum so only valid values end up in the db. -

Can I modify Django form data and post back to the page?
I want to use a django form, update some of the fields on POST (to the same page) and display the updated field values. There is no db involved here. I have a Django form. I am following the documentation here https://docs.djangoproject.com/en/4.2/ref/forms/) Here is my view code: def QuestionView(request): # if this is a POST request we need to process the form data if request.method == "POST": # create a form instance and populate it with data from the request: form = QuestionForm(request.POST) # check whether it's valid: if form.is_valid(): query = form.data["question"] result = chat(filepath=filepath, query=query) form.cleaned_data["answer"] += query result["answer"] form.cleaned_data["confidence_score"] = result["score"] # if a GET (or any other method) we'll create a blank form else: form = QuestionForm() return render(request, "home.html", {"form": form}) Here is my form code: class QuestionForm(forms.Form): question = forms.CharField(label="Question", required=1, max_length=255) answer = forms.CharField(label="Answer", required=0, max_length=16384) confidence_score = forms.IntegerField(label="Confidence", required=0, min_value=0, max_value=100)``` The line result = chat(filepath=filepath, query=query) is an external function that successfully returns an array of values. I can assign these values successfully to the form.cleaned_data. I cannot then render the updated cleaned_data back to the form.

How to solve CreateAPI 400 error in this DjangoRestFramework in Serializer Create Method?
I have a model, Doctor, that has a Foreign key relation to the user model. I'm handling the creation of Doctor instances through the serializer of the Doctor Model. The flow I'm going for is simply to check if a user with the given username exists.

Check constraint referencing fields of database object
Let's say I have a Django object like this: class X(models.Model): start_main = models.DateField("start X") And another like this: class Y(models.Model): x = models.ForeignKey(X, on_delete = models.CASCADE) start_sub = models.DateField("start Y") I want to add a CheckConstraint to Y that always ensures that Y.start_sub >= Y.x.start_main. Is this possible? I've looked into django.core.validators.MinValueValidator for example but that only takes concrete values as parameter. I've also looked into the check = models.Q(...) syntax but am unable to get syntactically correct constraint. -

django URL in a TextField with HTML
In my Django e-commerce project, I have an obvious Product model with an expected description field: description = models.TextField(...) I have the following url configured: path("product/slug:slug", views.product_detail, name="product_detail"), which, obviously, serves URLs like this: http://localhost:8000/product/foo and when a product foo is a part of a set with product bar, I want to add respective links to the description field on such products, like "you might want to buy bar together with this". However, adding a link to bar to the description of foo proved tricky. The whole description field (imported from a legacy ecomm app) can contain arbitrary HTML, and since it's not a user input, I render it like this in the template: {% autoescape off %} {{ product.description }} {% endautoescape %} When I add this to the (TextField) description: > This item together with <a href="product/bar">Bar</a> (sold separately) , the URL produced in the template is wrong: http://localhost:8000/product/product/bar/ , but if I don't use this '/product' in the description's url: > This item together with <a href="/bar">Bar</a> (sold separately) make > a matching set. , the URL is also wrong: http://localhost:8000/bar/ I'll admit, I don't understand how Django constructed the first or second URL. So it's ironic … -
How to aggregate an array of JSON Objects in Django with Postgres?
In Django 4.0+, I have an array of JSON objects that look like this: [{'type': 'ORG', 'data': "USA", "mentions": 8}, {'type': 'ORG', 'data': "CA", "mentions": 15}, {'type': 'PERSON', 'data': "Mahmoud", "mentions": 12}] So, in each row, I will have similar data like that in an object field called entities. What I am trying to achieve is to aggregate based on type with data and the total count of mentions of the same type and data and type in ALL rows. In my queryset, I have tried the following code to get the total mentions aggergate (unsuccessfully): def get_named_entities(self): named_entities = self.exclude(entities__exact={}).exclude(entities__isnull=True).values('entities__type', 'entities__data', 'entities').annotate( mentions=RawSQL("CAST(JSONB_AGG(entities->>'mentions') AS INTEGER)", ()) ).order_by('-mentions') Unfortunately, this doesn't work at all. -

Can a Django query filter with a relationship reference a parent's field value?
I have a Training and TrainingAssignment table in my django app. Users sign into the app and complete a Training which creates a TrainingAssignment record. The Training table has a field, days_valid which is used to determine whether or not a user has to re-take a training. I want an admin to be able to change days_valid on the fly to "invalidate" previously completed trainings. (e.g. changing a training thats good for a year to only good for one month.). I don't want the admin's changing of days_valid to go out and change the expiration date of thr TrainingAssignment record...I want those records to remain untouched for audit purposes. Instead, my code creates a new assignment if the employee is due. models.py class Training(models.Model): title = models.CharField(max_length=200) days_valid = models.IntegerField() class TrainingAssignment(models.Model): training = models.ForeignKey( Training, on_delete=models.CASCADE, related_name='training_assignments', blank=True, null=True ) date_started = models.DateTimeField(null=True,blank=True) date_completed = models.DateTimeField(null=True, blank=True) date_expires = models.DateTimeField(null=True, blank=True) In a query, I need to be able to get all Trainings where TrainingAssignment's date_completed + the Training's days_valid <= today.
