I want to get category id but I get None, what's the problem? Django
models.py class Post(models.Model): news = 'NW' articles = 'AR' POSITION = [ (news, 'Новость'), (articles, 'Статья') ] author_post = models.ForeignKey(Author, on_delete=models.CASCADE) category_type = models.CharField(max_length=2, default=news, choices=POSITION) date_created = models.DateTimeField(auto_now_add=True) category = models.ManyToManyField(Category) title = models.CharField(max_length=128, blank=False, null=False) text = models.TextField(blank=False, null=False) raitingPost = models.SmallIntegerField(default=0, verbose_name='Рэйтинг поста') class Subscription(models.Model): user = models.ForeignKey(to=User, on_delete=models.CASCADE, related_name='subscriptions') category = models.ForeignKey(to=Category, on_delete=models.CASCADE, related_name='subscriptions') signals.py @receiver(post_save, sender=Post) def subscribe_notify(instance, created, **kwargs): if not created: return print(instance.category) I need to get the category ID of a post that was just created.

Django 1.11 Subquery annotate with .exclude
Is it not possible to exclude inside a queryset? I always receive this error: ValueError: This queryset contains a reference to an outer query and may only be used in a subquery. The part of the code I am wondering why is it not working: def get_queryset(self): return self.queryset.annotate( foo_count=Subquery( Foo.objects.exclude(code__hash=OuterRef('hash')) .values('code') .annotate(cnt=Count('pk')) .values('cnt'), output_field=IntegerField() ), ) Thanks for any possible solutions! -
Prefetching implicitly related model instances
Let's say I have two models that look like that: class UserRequest(models.Model): # other fields deal_type = models.CharField(choices=DEAL_TYPE_CHOICES, max_length=10) class Company(models.Model): # other fields deal_types_interested_in = ArrayField( models.CharField(max_length=10), ) # this field has a set of choices from DEAL_TYPE_CHOICES As you can see thoses models have no explicit relationship with each other but an "implicit" one via the deal types. What I want to achieve is to query UserRequests and "prefetch" all Companys that have matching deal types. If those two models had a direct relationship (m2m) I could use prefetch_related like that: requests = UserRequest.objects.prefetch_related( Prefetch('companies', Company.objects.filter(deal_types_interested_in__contains=OuterRef('deal_type'))) ) But that doesn't work as there is no relation companies on the UserRequest model. How can I prefetch those Company instances anyways? I especially want the prefetch to only be evaluated when the queryset is evaluated, just like with prefetch_related. In other words I'm looking for a prefetch_related but for implicitly related models with no explicit through table and no predefined relation to each other. In my use case I have even more criteria than only the deal_type to match Companies to User requests but I omitted them for sake of simplicity. -

Stripe not working when getting needed variables from means other than GET parameters
I'm trying to submit a payment to Stripe using the documentation here. My goal is to submit a PaymentIntent and then check the status. The payment page I am creating is for a donation, so the amount can vary. As such, I'm trying to read the amount from my Django application into the stripe JS, and this is failing. This is my slightly modified code from the documentation example, which works fine: const items = [{ amount: "20" }]; let elements; initialize(); checkStatus(); document .querySelector("#payment-form") .addEventListener("submit", handleSubmit); // Fetches a payment intent and captures the client secret async function initialize() { const response = await fetch("/payment/intent/", { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ items }), }); const { clientSecret } = await response.json(); const appearance = { theme: 'stripe', }; elements = stripe.elements({ appearance, clientSecret }); const paymentElement = elements.create("payment"); paymentElement.mount("#payment-element"); } The problem comes when I try to replace const items = [{ amount: "20" }]; Based on this answer, I've tried grabbing the value from a hidden value, by the following (showing hidden field in template and line in JS to obtain value from hidden field): <input type="hidden" id="amount" name="amount" value="20"> and const items = … -
Determine whether 2 files are of similar file extensions in Python
I'm working on a project including a webapp, with the option for storing smaller files. Currently an uploaded file can be updated to a new version IF the format (file extension) of the files are identical. MyPainting.jpg can be replaced by a new file MyPainting2.jpg. To implement this logic I'm simply performing the following check if file_type != local_file_type: return Exception("These files are not of simmilar format") I wish to extend this logic so that .jpg files can also be replaced by .jpeg, ppt can be replaced by pptx and so on. One solution would be to hardcode some collection of simmilar types, but that seems awfully annoying to deal with. TLDR: Does some package, or system exist that can tell me whether or not 2 file extensions are similar? (jpg --> jpeg are similar, but png --> pdf isn't) I'm working in the Django framework, so if I could put some attribute on my HTML input field, that does the same, that would be a solution aswell. Note: It doesn't really matter to me if PNG and JPG are found to be similar. In technical/practical use, I don't actually need the files to be similar, I could update a … -
many-to-many link table - have multiple of FKs linked - general concept question (Django)
While this is Django related it is more of a concept question that is confusing me. I understand how to set this up in Django. I feel I have solved this before but it would have been a while ago and now suddenly I can't wrap my head around it anymore. This seems so simple so surely I must have a blank moment here? Here is a simple example: Pizza and Topings with a trough (m2m link) table that joins both. Question: How can I have multiples of one type linked to an instance of the other without creating additional fields for it? The issue is that those fields are all FK ids of course. I want an option to have unlimited toppings for a Pizza within ONE single column. Is that doable? Pizza Table Pizza A Pizza B Toppings Table Topping 1 Topping 2 Through Table Pizza A | Topping 1 Pizza A | Topping 2 Pizza B | Topping 1 Pizza B | Topping 1 & Topping 2 <<<<<---- how to do this with 1 column instead of 2? The first answer that came to me was to create a list or dict (or similar) within that DB … -

Django own templatestags
I have a question. I created own tags in django like this: from django import template from my_app.models import Post register = template.Library() @register.simple_tag def last_create_members(last=5): return Post.objects.order_by('created')[:5] And I wanted to displayed it.

Django: get model's fields name
I am trying to create a table in react that uses as table information from a django backend. I would like to fetch the table's columns from the API, so I tried updating the model: class Activity(models.Model): aid = models.AutoField(primary_key=True) uid = models.ForeignKey(USER_MODEL, default=1, verbose_name="Category", on_delete=models.SET_DEFAULT, db_column="uid") rid = models.IntegerField() action = models.TextField(max_length=254, blank=True, null=True) time = models.TextField(max_length=254, blank=True, null=True) table = models.TextField(max_length=254, blank=True, null=True) class Meta: managed = False db_table = "activity" @property def fields(self): return [f.name for f in self._meta.fields] I am trying to use fields() as the method to get all the model's "column" names, so that I can place them in the API's response, but it does not work. How can I get a django model's field names from the model's meta? -

djano support nested or flat values for a single field using single serializer

But there are few implementations where lower and upper are flat values and not nested. Like: "date_range": { "lower": "2023-01-21T00:00:00Z", "upper": "2023-02-21T23:59:59Z" } Now, I can set the value required=False and add lower/upper as flat fields like I've mentioned in the comments above. But I want to enforce it more "properly". Is there any other way where I can handle both payloads for nested and flat lower-upper values? -
django equivalent for mysql's JSON_OVERLAPS
