Django. Retrieving data from a related model for use in a form
How can I automatically associate a user with an id_ ticket and fill in a field in the form? Sample form - https://i.stack.imgur.com/9YMUv.png models.py class Ticket(models.Model): ticket_id = models.BigAutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID') ticket_title = models.CharField(max_length=100) ticket_date_open = models.DateTimeField(auto_now_add=True) user = models.ForeignKey(CustomUser, on_delete=models.CASCADE, verbose_name='User') class TicketMessage(models.Model): ticket_mes = models.TextField(verbose_name='Message') ticket = models.ForeignKey(Ticket, on_delete=models.CASCADE) user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) forms.py class TicketMessageForm(ModelForm): ticket_mes = forms.CharField(label='Answer', required=True) class Meta: model = TicketMessage fields = ('ticket_mes', 'ticket') views.py class Ticket(DetailView, CreateView): model = Ticket form_class = TicketMessageForm ticket_message = TicketMessage template_name = 'support/ticket.html' context_object_name = 'one_ticket' allow_empty = False def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['ticket_message'] = TicketMessage.objects.filter() return context def form_valid(self, form): obj = form.save(commit=False) obj.user = self.request.user return super(Ticket, self).form_valid(form) success_url = reverse_lazy('ticket_list') I assume that need to somehow take the data from the template and pass it to form_valid.

This is works, but it looks wrong and unsafe. <select class="d-none" name="ticket" required="" id="id_ticket"> <option value="{{ one_ticket.ticket_id }}" selected="">{{ one_ticket.ticket_id }}</option> </select> -
Async Request with OpenAPI Generator Python
Happy New Year EveryOne I have a particular Case in which i am using OpenAPI generator for calling the api in another Microservice. I have two microservices ie User and Customer so in Customer im am getting the information of the multiple users from User below is the example code from user.api_clients import User user_id = [1, 2, 3, 4, 5, 6, 7, 8, 9] user_list = [User.api.get(id=i) for i in user_id] and the above code will give me the user_data from User. In short it will hit user api from User 9 times one by one. So is there any way to hit this in a single shot with asyncio. I am new to this async thing in python. So ill really appreciate if anyone can give me an idea about how to do this. There is also a similar case like i want to get object from User model in oneshot for these user_id list. Yes i can use id__in=user_id but is ther anyway to hit the below code in oneshot like below code user_id = [1, 2, 3, 4, 5, 6, 7, 8, 9] user_obj = [User.objects.get(id=i) for i in user_id] Thanks for helping -

using method 'build_standard_field(self, field_name, model_field)' to overcame the error [<class 'decimal.InvalidOperation'>]
I'm writing a Django Rest Framework, and I want to use a generics.CreateAPIView to create an operation in my database. my models.py: class User(AbstractBaseUser, PermissionsMixin): uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) email = models.EmailField("Email Address", unique=True) first_name = models.CharField("First Name", max_length=150) last_name = models.CharField("Last Name", max_length=150) mobile = models.CharField("Mobile Number", max_length=150, blank=True) balance = models.DecimalField(max_digits=9, decimal_places=2, default=0.0, verbose_name=("Balance")) created_at = models.DateTimeField("Created at", auto_now_add=True, editable=False) class Operation(models.Model): sender = models.ForeignKey("User", related_name=("Sender"), on_delete=models.CASCADE) receiver = models.ForeignKey("User", related_name=("Receiver"), on_delete=models.CASCADE) amount = models.DecimalField(max_digits=9, decimal_places=2, default=0.0, verbose_name=("Amount")) created_at = models.DateTimeField("Created at", auto_now_add=True, editable=False) I want to send uuid values when creation the operation and handle the users filter in the backend using the view.

How to handle inline formset in post method of generic CreateView?

Django, common model used in several applications
In my project, there are applications named "developer" and "startup" In developer and startup application, i need a table named "languages", which implies that the language developer use and startup use. So i made model named "languages", But I'm thinking about whether to make this in developer application or startup application, or make a new application and make it in it. When I made it in developer application, i could use it by importing startup application models.py. But actually, I don't think that the table "languages" is more relevant to application "developler" than "startup". How should I do? I referenced link https://stackoverflow.com/questions/4137287/sharing-models-between-django-apps -
How to implement DB Connection Pool in Django

Is there a clean way to lower the cyclomatic complexity of Django templates?
I have a Django template I'm working on that takes an object that has multiple properties and adds different tags based on those properties. For example if object.bold == True it adds the <b></b> tag, and if object.strikethrough == True it adds the <strike></strike> tag. I've seen some other posts that smell which suggest nesting the ifs like: {% for object in objects %} {% if object.bold == True %} {% if object.strikethrough == True %} <b><strike>{{object.name}}</strike></b> {% else %} <b>{{object.name}}</b> {% endif %} {% else %} {% if object.strikethrough==True %} <strike>{{object.name}}</strike> {% else %} {{object.name}} {% endif %} {% endif %} {% endfor %} This code hurts me. I've also seen some wonky logic with only wrapping the beginning tags in if statements. Again, it's painful to introduce console errors. Is there a better, cleaner way to achieve this result without nesting ifs? I'm leaning towards making a custom Django tag but that seems like overkill for something that I'm really hoping can be simpler. -
