How do I generate Django seed data for a model that has a "through" field?
I'm using Python 3.9 and Django 3.2. I want to define Address objects for my Coop models, so I have set up these models ... class Coop(models.Model): = ,,, addresses = models.ManyToManyField(Address, through='CoopAddressTags') class CoopAddressTags(models.Model): coop = models.ForeignKey(Coop, on_delete=models.SET_NULL, null=True) address = models.ForeignKey(Address, on_delete=models.SET_NULL, null=True) address_is_public = models.BooleanField(default=True, null=False) My question is, how do I generate YAML seed data that creates the address, coop, and its join table data (CoopAddressTag), linking the two? address_pks = Command.get_and_print_address_yaml(file_path, city_pks) ... for row in input_file: id = row['ID'].strip().encode("utf-8", 'ignore').decode("utf-8") ... # Output the coop print("- model: directory.coop") print(" pk:",id) print(" fields:") print(" name: \"",name,"\"", sep='') print(" types:") for entry in types: print(" - ['", entry, "']", sep='') print(" addresses: [", address_pk, "]") print(" enabled:",enabled) if phone: print(" phone:",contact_phone_pk) if email: print(" email:",contact_email_pk) print(" web_site: \"",web_site,"\"", sep='') print(" approved: True", sep='') I need the Coop to exist before I can generate the join table data (CoopAddressTag), but then I'm confused about how to then enter the address data in the Coop in the YAML. -
In django models, how to add a constraint that looks across multiple rows
In the model below, I define a user, a habit the user is trying out, the start date (required) and end date (if the habit has ended). I want to add a constraint that each user can only be actively in one habit at a time. There is conceptually a few ways to determine this: For a specific user, only one habit has a NULL end date or for a specific user, the start-end range does not overlap for any of their habits, etc. I'm not sure how to approach writing this constraint, since it is looking across multiple rows instead of checking validity within one row. Any help getting started would be appreciated. from django.db import models from django.contrib.auth.models import User from django.db.models import F, Q class HabitChoices(models.TextChoices): NUTRITION = 'nutrition', 'Nutrition' EXERCISE = 'exercise', 'Exercise' SLEEP = 'sleep', 'Sleep' STRESS = 'stress', 'Stress' ALCOHOL = 'alcohol', 'Alcohol' SMOKING = 'smoking', 'Smoking' class HabitStatus(models.Model): """ This model keeps track, at a high level, of which habit the user is currently in.

How can I reset a forloop.counter0 in django?
I have a code in django that creates a carousel for each card item. As I am looping through each image for each specific card, I realized the forloop.counter will keep continuing until the initial for loop has finished. So in my example, i is my initial loop and p is my secondary loop. i loops through cards and p loops through images within the carousel of each card. I need to reset the counter after one i so that the carousel counter starts from the beginning so that first image of every carousel is active. I'd really appreciate any help {% for i in inspections %} <div class="card - mb-3" style="width: 40 rem;"> <div id="myCarousel" class="carousel slide" data-bs-ride="carousel"> <div class="carousel-indicators"> {% for p in photos.all %} {% if p.inspection_id == i.id %} <button type="button" data-bs-target="#myCarousel" data-bs-slide-to="{{ forloop.counter0 }}" class="{% if forloop.counter0 == 0 %} active {% endif %}" aria-current="true" aria-label="Slide {{forloop.counter0}}"></button> {% endif %} {% endfor %} </div> <div class="carousel-inner"> {% for p in photos.all %} {% if p.inspection_id == i.id %} <div class="carousel-item {% if forloop.counter0 == 0 %} active {% endif %}"> <img src="{{ p.InspImages.url }}" class="img-responsive mx-auto d-block w-80" height="300" alt="..."> </div> {% endif %} {% … -

Python migrations custom user model
I was wondering if anyone could point me in the right direction, please? I have built a custom user model as per the below code, however, when I run 'make migrations' it doesn't seem to pick up a few of the fields I have added in the custom user model. I think this is the cause of the following error message whenever I try to create a superuser.

Is there a way to add additional fields on an implicit many-to-many table in Django?
Consider the following models in models.py: class Volunteer(models.Model): account = models.OneToOneField( UserAccount, on_delete=models.CASCADE, related_name= "volunteer", primary_key=True) request_offers = models.ManyToManyField('Request', related_name="volunteers", blank = True) volunteer_communities = models.ManyToManyField('Community', related_name="volunteers", blank = True) class Request(models.Model): req_type = models.ForeignKey('RequestTypes', related_name="requests", on_delete = models.CASCADE, blank = False, null = False) A volunteer can have many request_offers(type of request). In the implicit appname_volunteer_request (many-to-many) table, I want another field called date besides the default fields -- id, request_id and volunteer_id. Is there a way to add an additional field on the implicit table without creating a through table? Thanks! :) -

django-filter list of links
I'm using django-filter's ChoiceFilter to generate a dropdown to filter results and it works great. However a dropdown is not what I have in mind for the design, instead I would like to use a list of links, but I can't find if there is such a filter.

Set is_staff to true for new users that created new accounts from CreateView
I am having problem with Django. I am using UserCreationForm and generic CreateView in order for people to sign up and create an account. The code is as follows: Custom form: class SignUpCustomUserForm(UserCreationForm): first_name = forms.CharField(max_length=200) last_name = forms.CharField(max_length=200) email = forms.EmailField(max_length=200) class Meta: model = User fields = ['first_name', 'last_name', 'username', 'email', 'password1', 'password2'] View: class SignUpView(generic.CreateView): form_class = SignUpCustomUserForm success_url = reverse_lazy('login') template_name = 'registration/signup.html' I do not have a model since I am using CreateView which basically handles the model. I want to automatically set every new created account as staff, but I can not figure out how to do it. Basically, I am working on a form which users can use to create an account with is_staff privileges and they can use those accounts to login to /admin (the default django admin). I tried setting model.is_staff to true in the Meta class inside the form class, but it didn't work out. Any advice or ideas is welcomed. Thank you -

Cannot assign "": "" must be a '' instance
I am trying to make a registration key in the UserModel where the key field in the registration form is a foreign key to another model called RegistrationKey. I have made two posts about this topic earlier without any success, however has a few things changed in my code which makes those previous posts irrelevant. In the form field, the field for the key is a CharField as I can not display the keys for the users due to safety. These are the two previous posts: Save user input which is a string as object in db , Textinput with ModelChoiceField These are my two models. class RegistrationKey(models.Model): key = models.CharField(max_length=30) def __str__(self): return self.key class User(AbstractUser): key = models.ForeignKey(RegistrationKey, on_delete=models.CASCADE, null=True, blank=True) Since my latest posts have I created a class based view, which looks like this: class RegisterPage(CreateView): form_class = MyUserCreationForm def form_valid(self, form): key = form.cleaned_data['key'] try: keyobject = RegistrationKey.objects.get(key=key) form.instance.key = keyobject return super().form_valid(form) except RegistrationKey.DoesNotExist: form.add_error('key', 'error') return super().form_invalid(form) When I try and pass in the value Admin which is an object in the RegistrationKey model I get the following error: 'Cannot assign "'Admin'": "User.key" must be a "RegistrationKey" instance.' I don't know how to … -

Easiest/Best way to restrict people/unknown from accessing Django API?
I've written a Django API and it works well however I want to restrict people/unknown hosts from writing requests to the API. This is because I have a React Frontend deployed at example.com and I want to make sure that only example.com can send requests to the API. I'm not entirely sure how to do this. I was trying to do research into cors however from looking at this thread How can I block calls from unknown domains/IP to my REST API?, it seems like cors can't prevent other hosts/unknown from making requests? I want to secure my API such that only my Frontend host at example.com can make requests to the API and other hosts can't (including stuff like Postman and curl shouldn't be able to make requests). How do I go about doing this? Any help in the right direction is very much appreciated! Thank you so much! -
Django ORM Query Optimization Issue
I am making a blog website and I am facing some issues with the Query performance. I have 3 models User Model -> Users (To store user email, Password etc) Post Model -> Actual Posts people Model -> (To store users extra information) Post Model -> class Post(models.Model): user = models.ForeignKey(User, on_delete=models.PROTECT) category = models.ForeignKey(Category, on_delete=models.PROTECT) title = models.CharField(max_length=255,null=True) description = models.CharField(max_length=1000,null=True) Likes = models.ManyToManyField(to=User, related_name='Post_likes') favourites = models.ManyToManyField(to=User,blank=True,related_name="favourite") People Model -> class People(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) photo = models.ImageField(upload_to='profile_pics', blank=True,null=True) Phone_number = models.CharField(max_length=255,null=True,blank=True) Birth_Date = models.DateField(null=True,blank=True) Created_date = models.DateTimeField(auto_now_add=True) Updated_date = models.DateTimeField(auto_now=True) Now as both of these models are connected to User model. I want to query the Post model and get the user photo in the template. Now when I use post.user.people.photo then for every post it generates a seperate query to DB resulting in slowness. I would like to use Join here to combines multiple tables and fetch all the records at once. I am currently using following Query -> posts = Post.objects.select_related().prefetch_related('images_set').annotate(comments_Count = Count('comments_post',distinct=True)).annotate(Count('Likes',distinct=True)).all().order_by('-id')
