Django folder structure for created file, static? media? or another one?
I want to create the file(.wav) by django and let it be downloaded by user. Currently I create the file under /myproj/static directory. However it is mixed with the other jpg/img files, so,, it's not good design? then, I read the document about /myproj/media directory but it is said used for user upload files. So,,, how is the good directory design for server created file? Should I create such as /myproj/create_wav? but how can user access this url in template? Thank you for any idea or helps. -

Django - No module named 'mywebsite'
I have a django app that I downloaded from a Github repo where the main app is not called "mywebsite" (like instructed in the django tutorial). Everytime I run python manage.py runserver i get the following error. Conceptually I understand the error, but practically I don't. The issue can't be that I have always need to name my repo "mywebsite" right? This is the current repo structure.

Should i allow user to use the admin panel to upload his blog?
I'm building an app for someone, one of its function is it allowers the owner to upload blogs to the website. So i'm wondering if i should create a page for uploading blog or just give him staff permission so he can create and upload it through django's admin panel. I want to know if this is safe or if it will be worth it to create a front-end template for just one person to use. -
WooCommerce webhooks with Django Rest Framework
I am trying to integrate WooCommerce webhooks with Django but without success. I found a solution to a similar issue, but still cant make it work. The thing is that, Woocomerce is generating this secret key automatically. I guess that I have to hard code it by myself in the admin panel ? Also about the code bellow(solution found in the web), Django is complaining that request has no property payload. I guess that it must be data ? mport base64 import hashlib import hmac request_sig = request.headers.get("x-wc-webhook-signature") signature = hmac.new(<your_secret_key>.encode(), request.payload, hashlib.sha256).digest() if hmac.compare_digest( request_sig.encode(), base64.b64encode(signature) ): return True return False enter code here -

4 products on the same line in the template
I'm developing an e-commerce with Django. My backend is fine, my problem is with the template. Currently, I want to display 4 products per row, and if there are 7 products, the other 3 must be aligned with the top one. I'm using bootstrap to do this, however, for some reason I don't know, it doesn't have 4 products on the same line, even with space. I'm using a container with 1200px. home.html <div class="container"> <div class="row"> <div class="col-lg-8"> <div class="row"> {% for product in products %} <div class="card mb-4 border rounded" style="width: 13.5rem;"> <a href="{{ product.get_absolute_url }}"> {%if product.image %} <img class="img-produto" src='/media/{{product.image}}' class="card-img-top hover_img "> {% else%} <img class="img-produto" src="{% static '/img/not-found-product.jpg' %}" class="card-img-top hover_img"> {%endif%} </a> <div class="card-body"> <p class="card-title">{{product.name}}</p> <p class="card-text"><i class='fas fa-dollar-sign' style="margin-right:2px"></i>{{product.price}}</p> </div> </div> {% endfor %} </div> </div> </div> </div> base.css @media (min-width: 900px){ .container{ max-width: 1100px; } } -

django-tenants global device table mapping to tenants
We are using django-tenants to provide a multi tenant solution for an iot platform and I'm having an issue figuring out how to map some global data to tenant specific tables. Basically we have iot devices that talk to a node.js server using a proprietary protocol over tcp, that server then makes rest api requests to a Django webserver to update the database with device measurements. The node server does not know anything about which device belongs to which customer so it needs to have a rest api that is global and then the webserver backend will need to map that device to a specific tenant but we cannot let tenants view each other's data so I'm not sure how we accomplish this as it seems apis are either tenant specific or global (public). -

django rest framework Viewset for single item, not list
I am having a problem with my DRF API. I want to provide a read only endpoint that takes a single id from a object(document) in the DB and runs a script to perform an check and gives back the result. It works fine when I call the API with //api/documentcheck/1/ where 1 is the pk of the document in the DB. The problem is that if I just call the base URL //api/documentcheck/ it tries to give back the results of all documents in the database and times out because it takes ages. I am looking for a way to remove the list view and force users to provide the ID for a single document to check. This is my serializer class class DocumentCheckSerializer(serializers.Serializer): '''Serializer for document check''' class Meta: model = Document fields = '__all__' def to_representation(self, value): return process_document(value) This is my view: class DocumentCheck(viewsets.ReadOnlyModelViewSet): """Check a single document""" authentication_classes = ( TokenAuthentication, SessionAuthentication, BasicAuthentication, ) permission_classes = [IsAuthenticated] queryset = Document.objects.all() serializer_class = serializers.DocumentCheckSerializer and my router entry router.register("documentcheck", views.DocumentCheck, basename="documentcheck") -
I'm tyring to make an API following instructions on CodewithMosh
I'm learning python on a website called codewithmosh.
