How to address N+1 problem in django with prefetch related?
With the following code I am getting N numbers of queries based on the loop. How to avoid that ? I tried using prefetch_related but that didn't worked or am i doing the wrong way ? models class Product(models.Model): name = models.CharField() .... class ProdcutOffer(models.Model): product = models.ForeignKey(Product, related_name="offers") .... def my_view(request): qs = Product.objects.filter(is_active=True).prefetch_related("offers") data = [] for product in qs: data.append( { ...., "offer":product.offers.filter(is_active=True, is_archived=False).last() } ) paginator = Paginator(data, 10) try: page_obj = paginator.page(page_num) except PageNotAnInteger: page_obj = paginator.page(1) except EmptyPage: page_obj = paginator.page(paginator.num_pages) return page_obj -

Designing a Generic List Manager Library with User Permissions in Django/Python
I'm currently in the process of developing a versatile and reusable Generic List Manager Library for applications built with Django/Python. This library aims to provide a generic solution for creating and managing lists of various entities Here are the key requirements for this generic library: User-List Association: A list should be associated with one or multiple users. User Permissions: Users linked to a list should have different permissions such as read, write, and share rights. Abstract Lists: Lists should be abstract and capable of linking to a single model, with a field defining the primary model it references. Multiple Models: It should be possible for two different lists to point to different models. I am seeking advice on what are some suitable design patterns for doing this. I am thinking of using a combination between Repository Pattern && Mediator Pattern to implement this, but I would love to hear different opinion or takes into this. -
I am unable to update value of lifecycle stage using hubspot api
I am using hubspot api to update the value of lifecycle stage of a contact. The value can be changed to any other value in the hubspot crm. But when I am using the api to do so, I can change the value of the lifecycle stage to a higher stage say, from a Subscriber to Lead, as Subscriber is lower in rank than Lead. But when I try to change the value from Lead to Subscriber using the api, it doesn't do so. There is no error too. I am not sure if it is a bug with the api or there is some restriction to do so. The code for my api: def update_contact_lifecycle_stage(request , *args): try: api_client = HubSpot(access_token=HUBSPOT_API_KEY) #get this from params contact_email = "test@test.com" filter_query = { "propertyName": 'email', "operator": 'EQ', "value": contact_email } filterGroup = { "filters" : [filter_query] } search_request = PublicObjectSearchRequest( filter_groups= [filterGroup], properties=['vid'] ) response = api_client.crm.contacts.search_api.do_search(public_object_search_request=search_request) contacts = response.results if contacts: contact_vid = str(contacts[0].id) #Get this from params new_lifecycle_stage = "subscriber" contact_update = { "lifecyclestage": new_lifecycle_stage } simple_public_object_input = SimplePublicObjectInput( properties=contact_update) try: api_response = api_client.crm.contacts.basic_api.update( contact_vid, simple_public_object_input=simple_public_object_input ) except ApiException as e: print(f"HubSpot API error: {e}") except Exception as e: … -

Django Permission per Database Object
I have an architectural question regarding Djangos permission model. I do have a Database Model which hold companies, and each company can have multiple projects. Users should be able to only see companies that they are assigned to and only see projects which they are assigned to. I am now confused whether I should have a Many2Many Relation in the companies and projects which holds the allowed users and then check them on access through the permission system? Or create a new permission for each company, add this permission to the company and/or project and then give the users these permissions? Somehow I think solution 1. gets me into problems in the long run when querying all projects one user should see. But solutions 2 got me stuck since there is no permission field in the models, so I always have to cast string field to permission and I will generate a huge amount of permissions overall. Maybe I am completely overthinking this? What would be the best approach to per Database-Entry permissions? Thanks and Best Regards -

How to avoid client caches (Chrome) on django react app?
I have a django-react app that is serving out of Heroku. I use webpack to build static files, which I serve out of a Django app called frontend. Django static files serving adds a hash to the webpack generated files for cache breaking on new releases. To illustrate, here is the index.html that is served for my site: <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <link rel="icon" href="/static/favicon.e62ca627caf.ico" /> <meta name="viewport" content="width=device-width, initial-scale=1" /> <meta name="theme-color" content="#000000" /> <link rel="stylesheet" type="text/css" href="/static/frontend/css/index.e861872e9ba7b.css"/> <link rel="manifest" href="/static/manifest.a22d2aecab21fe.json" /> </head> <body> <div id="root"></div> <script src="/static/frontend/js/index.a39c981a0accf.js"></script> </body> </html> Cache-Control for index.html is set to max-age=0. I thought this setup would be good enough for breaking client caches when I release a new frontend version of my site (since index.*.js would have a new hash). However, I observed that some of my clients had stale versions up to two weeks ago even with this setup (using Chrome on Windows). How is this possible? Am I missing something to break client caches for new frontend releases? -

Django - inconsistent password hashing
Trying to build the user manager boilerplate of a Django (DRF) project. Facing some really weird issues when registering a user. First problem I encountered was passwords not being hashed. After some investigation I found out that the auth package has make_password function, which generates a hash from a given string. But then I noticed that I cannot authenticate these users. Tried to setup my own authentication logic using the check_password of the same package, when I realized, that the password hash stored in the database is completely different from the hash generated by make_password and passed to the set_password method of the user instance. I know I should provide some code, but the computer running the code doesn't have internet access (my wi-fi adapter has died) , but the structure of the user manager, view and serializer is almost same as here: https://github.com/dotja/authentication_app_react_django_rest/tree/main/backend I do use user.save() after setting up the password. I need to figure out either why the user's password not getting hashed without using the make_password function, or why the stored hash is different when using the make_password function. Thanks. -

When I click submit button it only redirects me to my other page, nothing happens with submitted data and data is not saved to my db. I looked for solution in multiple sources but didn't find one. I am begginer with this topic so every feedback would be great. My questions: Where I made mistake If i have prepopulated slug field in my admin.py (from title field) will it be prepopulated in forms when i exclude my slug field? 3.I would appreciate for useful knowledge sources. model.py class Task(models.Model): is_done = models.BooleanField(default=False) title = models.CharField(max_length=100) add_time = models.DateTimeField(auto_now_add=True) deadline = models.DateTimeField() user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="user") slug = models.SlugField() description = models.TextField() forms.py from django import forms from .models import Task class TaskForm(forms.ModelForm): class Meta: model = Task exclude = ["add_time", "is_done"] template <form method="post" class="form" action="{% url 'add-task' %}"> {% csrf_token %} <p>Title: {{ form.title }}</p> <p>Deadline: {{ form.deadline }}</p> <p>User: {{ form.user }}</p> <p>Description: {{ form.description }}</p> <button type="submit">Submit</button> </form> views.py def add_task(request): if request.method == 'POST': form = TaskForm(request.POST) if form.is_valid(): form.save() return HttpResponseRedirect("/todolist") form = TaskForm() return render(request, "todolist/add_task.html", … -
Django generating python file
I am building site in django and I have table with data: <th>name</th> <th>data</th> data is necessary in my client-side python program sender.py. User double click on specific row and using pyinstaller compile it with data which user selected stored as const in python program and then download it. I manage to make JS script witch shows what row you selected, but I cant figure out how to insert data into python program, use run pyinstaller on that file and then download it. Python program have function which takes that data but is not necessary Python: from somelib import func constData = data def clientFunc(constData): if constData != None or len(constData) <= 0: print("Argument constData is valid") else: constData = str(constData) client = func(constData, 9999) client.func2() or from somelib import func constData = data if constData != None or len(constData) <= 0: print("Argument constData is valid") else: constData = str(constData) client = func(constData, 9999) client.func2() JS: const table = document.getElementById('table'); const rows = table.getElementsByTagName('tr'); Array.from(rows).forEach((row, index) => { row.addEventListener('dblclick', () => { const cells = row.getElementsByTagName('td'); console.log(cells[0]); console.log(cells[1]); const content1 = cells[0].innerHTML; alert(content1) }); }); I will be grateful for at least one of these things. Cheers! -
NextJS and Django Project Deploy
Does anyone know how to deploy the django+nextJs app currently, my frontend is running on localhost:3000 and Django at 127.0.1:8000 and its is working perfectly on my local machine I want to deploy it on a live server anyone who knows how to do this I have deployed the next app on Vercel (https://cropsight-dusky.vercel.app/) but it will not move further from login unless Django is also running simultaneously. I have checked it If the nextJs project is running on Vercel and my Django is running locally then the request from front end will come to me
