Django Admin - dynamic select options with foreignkey and manytomanyfields
Here the supplier is related to Supplier model (ForeignKey) and substrate is with Substrate (ManyToManyField). The main model here is SupplierInfo from which we can filter suppliers and get their respective substrate. When ever admin clicks on the dropdown of Arrival_supplier and, SupplierInfo_substrate should be filtered with the supplier name and should be able to receive SupplierInfo_substrate inside Arrival_substrate. The Arrival model, where the filtered SupplierInfo_substrate should be saved. class Arrival(models.Model): submitted_on = DateTimeField(auto_created=True, null=True, blank=False, editable=False) edited_on = DateTimeField(auto_now_add=True) submitted_by = ForeignKey(get_user_model(), on_delete=models.SET_NULL, null=True) supplier = ForeignKey(Supplier, null=True, on_delete=models.SET_NULL) arrival_date = DateField(auto_now_add=True, null=True, blank=False) substrate = ManyToManyField(Substrate, blank=True) The Substrate and Supplier models, which are connected to Arrival and Supplier. class Substrate(models.Model): name = CharField(max_length=299, unique=True, null=True, blank=False) class Supplier(models.Model): name = CharField(max_length=299, unique=True, null=True, blank=False) The SupplierInfo model, from which supplier and its substrate should be filtered. Note: One supplier can have multiple substrates. Simply, filtering supplier returns multiple query set each with a different substrate (ForeignKey) name. class SupplierInfo(models.Model): supplier = ForeignKey(to=Supplier, on_delete=models.SET_NULL, null=True, blank=False) substrate = ForeignKey(to=Substrate, on_delete=models.SET_NULL, null=True, blank=False) mushroom = ForeignKey(to=Mushrooms, on_delete=models.SET_NULL, null=True, blank=False) weight = FloatField(null=True, validators=[MinValueValidator(0.9)],blank=False) yield_min = FloatField(null=True, validators=[MinValueValidator(0.9), MaxValueValidator(100)]) yield_max = FloatField(null=True, blank=True, validators=[MinValueValidator(0.9), MaxValueValidator(100)], ) status = BooleanField(null=True) -

How to capture certain information in a session from a form using ajax
I am trying to learn Django and I am making an eCommerce site that has sessions. I building the cart app and I intend to capture qty, price and item.id in a session using AJAX. To understand the concept, I am attempting to capture only the itemid from the HTML. Unfortunately after a few attempts I haven't been able to update the session. I know the session is not updating from running manage.py shell after clicking the "add to cart" button on the page by decoding the session info using the method below: from django.contrib.sessions.models import Session s = Session.objects.get(pk='<sessionid from chrome cookies>') s.get_decoded() Result = {'skey': {}} Here is my cart app: class Cart(): def __init__(self, request): self.session = request.session cart = self.session.get('skey') if 'skey' not in request.session: cart=self.session['skey'] = {} self.cart = cart def add(self, item): item_id = item.id if item_id not in self.cart: self.cart[item_id] = {'price':str(item.price)} self.session.modified = True Here is my AJAX script: <script> $(document).on('click'), '#add-button',function (e) { e.PreventDefault(); $.ajax({ type: 'POST', url: '{% url "store_cart:cart_add" %}', data: { itemid: $('#add-button').val(), action: 'post' }, success: function (json) { }, error: function(xhr,errmsg,err) {} }); }) </script> Here is my html form I am dealing with: <form class="cart … -
I have a slight misunderstanding about Django’s user’s authentication system
How does Django create users? Does it create users automatically? For example, when someone opens a Django site, is a user object automatically created? I see in a lot of codebase, they use request.user to access the logged in user in views.py but then again, does a user need to login before the User object is created? I have an application I want to create but then, I wouldn’t want to create a Django login system since most users will be logging in only via some third party OAUTH service, like login with Spotify or something. In this case, is there a way to merge both authentication systems? Can I still access the logged in user using request.user? -

handle duplicate attribute in django model fields, looking for best practise
I'm having a senario, where my model have different fields but the share the same attribute for example I have the following model: class Skills(models.Model): pace = models.IntegerField() shooting = models.IntegerField() passing = models.IntegerField() dribbling = models.IntegerField() defending = models.IntegerField() physic = models.IntegerField() gk_diving = models.IntegerField() gk_handling = models.IntegerField() gk_kicking = models.IntegerField() gk_reflexes = models.IntegerField() gk_speed = models.IntegerField() . . . So Is there a way that can let me writing my model in better way? I mean when I want to update, for example, from models.IntegerField() to models.IntegerField(validators=[MaxValueValidator(100),MinValueValidator(1)]). I have to do the update for the whole fields. -
is it possible to pass template variable to django template tag
I created a custom django template tag and it accepts few arguments. Now the problem I am facing is that, the argument that would be passed to template is dynamic and dependent on the value passed from view function. suppose template has value arg1 and I want to pass it to template tag, so I do like {% custom_tag {{arg1}} %} but it doesn't interpret arg1 as variable but a string, any workaround? -

getting all records with same foreign key in django
I'm working on my first project in Django/Postgres, an app to track plant breeding projects. I have a Generation model that connects to a Project model with ForeignKey (i.e., each breeding project consists of multiple generations of offspring): class Generation(models.Model): # ... project = models.ForeignKey( Project, related_name="generations", on_delete=models.CASCADE ) I'd like to add a generation_number field that auto-increments based on the associated project - if there are already 3 records with the same foreign key in the Generation table, then the next record created with that FK should get assigned a generation_number of 4. My understanding is that I can't use an AutoField because this is not a primary key, so I'm trying to write a method that counts the number of records with the same FK and adds 1, something like: def increment_gen_number(self): last_count = Project.objects.filter(pk=self.project).count() return last_count+1 gen_number = models.IntegerField(default=increment_gen_number) I'm guessing there are some syntax issues since I'm still new to Python and this feels like a bit of a kludge. How can I get this to work? -

Django Annotate and aggregate behaviour clarification. Auto filtering?
Im writing an API in DRF and had some questions on the behaviour of annotate and aggregate on query sets. So I essentially have models Product, Producer, and a model inventory. An inventory contains a product fk, producer fk and quantity and price fields, among other unimportant fields. I have a view which lists out all the inventory items, and filters them based on producer. Im trying to annotate the query set to aggregate and sum the quantity of each product among all inventory items. Initially I just referenced the quantity field directly. That way works apparently, however Im suspicious because it works even if I don't specify that it needs to filter entries based on product. For safety, I access the product model from the inventory model, and then did a reverse relationship from product back to inventory, and referenced the quantity to be aggregated. I get the same expected values, and in this way I understand why its working, however it feels inefficient. I need some clarification on why the simple solution works, and if I should use it, since nowhere am I filtering my product, however the aggregated values are aggregated based on product. class Inventory(models.Model): item_ID … -

Django REST framework TokenAuthentication returns anonymous user
How do I properly implement DRF TokenAuthentication without the request object returning an anonymous user when I try to log in? according to the docs, when authenticated, the TokenAuthentication object provides the request.user which is the Django user instance and the request.auth which is the token instance. But even after authentication, request.user returns anonymouse user. What could I be doing wrong? Client request: //function to get token export default function axiosConfig() { // request header const headers = { "Content-Type": "application/json" } // Get token from local storage.

I have a problem with creating a profile instance in Django. when I try to update a profile the images of the profile don't save in the database My guess is that the form.save(commit=False) does not upload the photo nor update the field as it should but I do not understand why : here is my code: models.py class Profile(models.Model): user = models.OneToOneField(User, primary_key =True, on_delete=models.CASCADE, related_name= 'profile') image = models.OneToOneField(UserImage, on_delete=models.SET_NULL, null=True, blank=True) phone_number = models.CharField(max_length=50, null = True, blank = True) followers = models.ManyToManyField(User, related_name='follower', blank=True) following = models.ManyToManyField(User, related_name='following', blank=True) biography = models.TextField(max_length=250, null=True, blank=True) class UserImage(models.Model): avatar = models.ImageField(blank=True, null=True,upload_to='avatar_pic') header_image = models.ImageField(blank=True, null=True,upload_to='header_pic') forms.py class ProfileForm(ModelForm): class Meta: model = Profile fields = ( 'phone_number', 'biography', ) class ImageProfileForm(ModelForm): class Meta: model = UserImage fields = ( 'avatar', 'header_image', ) views.py @login_required def CompleteSignUp(request): if request.method == 'POST': profile_form = ProfileForm(request.POST,request.FILES ,instance=request.user.profile) image_profile_form = ImageProfileForm(request.POST, instance=request.user.profile.image) if profile_form.is_valid() and image_profile_form.is_valid(): profile = profile_form.save(commit=False) images = image_profile_form.save() profile.user = request.user profile.social = social profile.image = images profile_form.save() return redirect('blog:Home') else: profile_form = ProfileForm( initial={ 'phone_number':request.user.profile.phone_number, 'biography':request.user.profile.biography } ) if request.user.profile.image: image_profile_form = ImageProfileForm( initial={ 'avatar':request.user.profile.image.avatar, 'header_image':request.user.profile.image.header_image } ) else: image_profile_form = ImageProfileForm() return render(request, 'user/createprofile.html', {'form_p': … -
