How can i enable the agent instance to be available in my agent update form when the agent is connected to the user through a one to one field
models.py class Auto(models.Model): user = models.OneToOneField("User", on_delete=models.CASCADE) def __str__(self): return self.user.username class User(AbstractUser): pass # To categorize users either as an organisor or as an agent is_organisor = models.BooleanField(default=True) is_agent = models.BooleanField(default=False) agent_details = models.TextField(null = True, blank=True) class Agent(models.Model): user = models.OneToOneField("User", on_delete=models.CASCADE) organisation = models.ForeignKey("Auto", on_delete=models.CASCADE) def __str__(self): return self.user.username views.py class Agent_update(ManualLoginRequiredMixin, generic.UpdateView): template_name = 'agent-update.html' form_class = AgentUpdateForm queryset = Agent.objects.all() context_object_name = 'agents' def get_success_url(self): return reverse('reverse url') agent-update.html <form method="post"> {% csrf_token %} {{form|crispy}} <button>Update Agent</button> </form> After running the server the form works but dosen't display the instance of the particular agent being updated. I feel it is because the Agent model is connected to the User model. Any help would be appreciated -

How to search inside string and modify
Python newbie here. A script I am using has a method s_lower(value) to lowercase every text posted by user. Also there are some special syntax such as [spec sometexthere]. I want to not lowercase if the text has a special syntax (in this case [spec ...] but lowercase all other text. For example, THIS IS A TEXT [spec CAPITAL] EXAMPLE This should be rendered as this is a text [spec CAPITAL] example Unfortunately, I wasn't be able to see/write logs (maybe because of docker), so I am kind of blind but hopefully this code block below will give you some hint to guide me WEBURL = r"(?:(?:(?:(?:https?):)\/\/)(?:(?!(?:10|127)(?:\.\d{1,3}){3})(?!(?:169\.254|192\.168)(?:\.\d{1,3}){2})(?!172\.(?:1[?") # actually much more longer def s_lower(value): url_nc = re.compile(f"({WEBURL})") # Links should not be lowered if url_nc.search(value): substrings = url_nc.split(value) for idx, substr in enumerate(substrings): if not url_nc.match(substr): substrings[idx] = i18n_lower(substr) return "".join(substrings) return value.lower() I want something like if the value has "[spec" then find the index number of "[" and "]", then do not lowercase the text between those parantheses but lowercase all other text. -

Dockerizing Django with PostgreSQL. FATAL: password authentication failed for user "postgres"

Best practice to use django db connection in network call
I have two Django projects with DRF and have some Rest API's I want to use db connection of one Django project to another so i need to pass db connection/credentials over api network. I know we can get connection object using following from django.db import connections db_conn = connections['default'] and what am thinking is 1- to pass above db_conn in an api call as parameter to second project api but when am getting on other side its showing as string not as db connection object. 2- Another option is to pass credentials and create connection using sql alchemy in second project. So what is the best approach in above two scenarios?. Also it would be great if you can answer how to pass db connection object in api params as object not string -
How to apply a filter for each row of the same queryset on Django
I have the a model Product which has a relation with itself using the key "parent". This way, to get the parent of a product i just do product.parent and if i want the children of a product i do product.product_set.all(). What i want to do is to do an annotate on a queryset of parent products and sum the stock of each product with the stock of its children. Something similar to this: qs = Product.objects.filter(is_parent=True) qs = qs.annotate(stock_sum=Sum(Product.objects.filter(parent_id=F('id')).values_list['stock'])) Is this possible? Will it result in many queries or django know a way of handling this with a few joins? -

Django Query across multiple models
So I am looking for some help (and hopefully and explanation) of how I access data across my multiple models because this one has left me completely snookered. I have a system for the sale of events (events model) now these events have multiple products(products model) and variable prices dependant on when you book (prices model), this part is working fine. Where I am struggling is there are also bundles of products (bundles table) which contain multiple products, and I need to get their attached prices. Now I have a list of bundles attached to the products being viewed but am struggling to query the ORM and get a full record - <Products (multiple)> - . I'm not completely new at this but it has left my completely stumped so any help would be greatly received. I have attached a sketch of the DB to help visualise. Thanks -
