/admin/password_change/ and /accounts/password_change/ use the same template unless I manually specify some urlpatterns
Problem I am using both django auth and django admin. After registering these in urls.py, visiting /accounts/password_change/ and /admin/password_change/ are using the same template. This is not what I want. Environment The following is my project layout, or at least the relevant parts: . +-- config | +-- settings.py | +-- urls.py +-- timelog | +-- templates | | +-- registration | | | +-- password_change_done.html | | | +-- password_change.html | | +-- app1 | | | +-- (templates) | | +-- app1 | | | +-- (templates) | +-- app1 | +-- app2 +-- manage.py TEMPLATES setting: from pathlib import Path ROOT_DIR = Path(__file__).resolve(strict=True).parent.parent.parent APPS_DIR = ROOT_DIR / "timelog" TEMPLATES = [ { "BACKEND": "django.template.backends.django.DjangoTemplates", "DIRS": [str(APPS_DIR / "templates")], "APP_DIRS": True, } ] urls.py: from django.conf.urls import include from django.contrib import admin from django.urls import path urlpatterns = [ path("accounts/", include("django.contrib.auth.urls")), path("admin/", admin.site.urls), ] Current workaround The only solution I found was to override /accounts/password_change/ and /accounts/password_change/done/. I found it necessary to rename the templates so that include("django.contrib.auth.urls") wouldn't screw things up. Updated urls.py from django.conf.urls import include from django.contrib import admin from django.contrib.auth import views as auth_views from django.urls import path urlpatterns = [ path( "accounts/password_change/", auth_views.PasswordChangeView.as_view(template_name="registration/change_password.html"), … -
How to know the count of many to many fields of an random model?
I have an random model: class Model(models.Model): other_field1 = models.SomeField(...) m2m_field1 = models.ManyToManyField(...) other_field2 = models.SomeField(...) m2m_field2 = models.ManyToManyField(...) other_field3 = models.SomeField(...) I want to know the count of fields that correspond to the relation many to many and the count of other fields. In the example above, I have 2 fields with a many-to-many relationship and 3 other fields. -
How to allow the update of only 1 field?
So Im doing an app where the user can upload photos, each photo has a user, image, description, and other fields. When the user creates a new photo, the image is required, but when the user wants to update it, you only can change the description. I'm stuck with this, first tried with update (put) but it's clearly not the method to use, now I'm trying with partial_update but I can't get it right. This is what I have right now, it gives me the error: TypeError: Object of type Photo is not JSON serializable. Maybe it's a completely wrong way of doing it. View: class PhotoViewSet(mixins.RetrieveModelMixin, mixins.CreateModelMixin, mixins.UpdateModelMixin, mixins.DestroyModelMixin, viewsets.GenericViewSet): """ PhotoViewSet Handle upload (create) and delete of photos.

Get queryset and it's aggregated value at one db query
In Django rest framework view I am making a complex Product annotated queryset which goes to serialization, but at the same time, I need to get its aggregation data to add it to the Response data. Example (one query): qs = self.filter_queryset(Product.objects.filter(**query_filters) .annotate(current_price=F('some_value') * some_vart))) Then I need aggregated data(second query): min_max = qs.aggregate(Max('current_price'), Min('current_price')) This produces 2 DB queries total. Is there any way to make it hitting DB once? DB is Postgres. Thx -
Django migrations weren't unapplied
I've developed a custom package to sync some models with s3 bucket. When I installed it on my django app, and ran the CI, the migrations weren't unapplied. The unapplying migrations are behaving unexpectedly: It tries to unapply twice the same migration (recommendations.0011_auto_20210725_1253): Operations to perform: Unapply all migrations: lakehouse_sync Running migrations: Rendering model states... DONE Unapplying lakehouse_sync.0001_initial... OK INFO:botocore.credentials:Found credentials in shared credentials file: ~/.aws/credentials Operations to perform: Unapply all migrations: profiles Running migrations: Rendering model states... DONE [...] Unapplying recommendations.0011_auto_20210725_1253... OK [...] Operations to perform: Unapply all migrations: recommendations Running migrations: Rendering model states... DONE Unapplying recommendations.0011_auto_20210725_1253 And it happens because Django doesn't detect that they were unapplied. lakehouse_sync [X] 0001_initial profiles [X] 0001_initial [X] 0002_auto_20210723_0857 recommendations [...] [X] 0011_auto_20210725_1253 However, there aren't those tables on my db I have no idea how to proceed with that, could someone give me a clue at least to solve this issue? -

Django run javascript before render_to_string
I am building a application that dynamically fill in forms and converts it to pdf. To build the pdf I pass in html code (pdfkit.from_string()) and to build the html code I am using Django templates. I need to run some Javascript code to mark some input checkboxes as checked, however render_to_string will just generate the html without running the javascript to mark the items as checked. my_template.html {{checked_items|json_script:'items'}} <script src="{% static 'form_render.js' %}"></script> form_render.js const items = JSON.parse(document.getElementById("items").textContent); let form_checkboxes = document.querySelectorAll('input[name="my_checkboxes"]'); for (let i of form_checkboxes) { items.includes(i.value) ?

Pyhton django, when creating an registering form how to get this .get method working?
I started to watch Corey Schafer's django website tutorial and everything was going great until now. unlike in the video after registering site doesn't sends me to home page. It does nothing.

Any ideas why :( and also .method functions seems to be not working it is white in VSC from django.contrib import messages from django.contrib.auth.forms import UserCreationForm from django.shortcuts import redirect, render def register(request): if request.method =='POST': form = UserCreationForm(request.POST) if form.is_valid(): username=form.cleaned_data.get('username') messages.success(request,f'Account Created for {username}') return redirect("blog-home") else: form=UserCreationForm() return render(request,'users/register.html',{'form':form}) -
Django: How to delete models in real time
I am working on a subscriber confirmation system with Django, and I do not want random/spam subscribers. So I came up with a confirmation system. Once the subscriber clicks the subscribe button, a Subscriber model is created. However, it is not confirmed. I send a confirmation email and only if the subscriber clicks on the link in the email will the model be confirmed. The problem with this system is that an unconfirmed subscriber stays and is not deleted. How do I write a function that deletes the unconfirmed subscribers if they did not confirm in, say, 2 days? models.py class Subscriber(models.Model): email = models.EmailField(unique=True) confirmed = models.BooleanField(default=False) creation_date = models.DateTimeField('date published', blank=True, null=True) #my function for deleting subscribers def confirm_date(self): today = date.today().toordinal() if today - self.ordinal_creation >= 2 and self.confirmed == False: self.delete() -
how do I create an online compiler? like TIO?
So, I'm working on a hobby project, and so basically what I want is something like 'TIO' (try it online) Where the user would enter the 'code' hit 'Run', and the server would return the appropriate output firstly I was thinking of using a third party library Python-tio-github and simply sending a request to the 'Tio' website, but that doesn't seem right, I mean is that allowed?, is there any other way? how am I supposed to go about it? My Setup: I'm using Django, 'Rest Api' with Angular 10, and I'm planning on running this on Digital Ocean I could run the TIO on my website server (as it's open-source) but I doubt the server would be able to handle it? running Django, node(angular), and MySQL along with TIO? the main goal of this project is for me to learn, so, even if I could have only a single language compile (Python) I'd be happy, I just don't have ANY clue on how and where I'd start looking. thanks in advance! -

Update Django ImageField through .update() ORM
Similar questions have been asked here: Update ImageField without forms in django, and Django ImageField is not updating when update() method is used But the answer has always been the same ("use .save() instead") - this solution does work, but because of signals on the model which I can't control, I would like to know if there are any work-arounds that can be used instead. # serializers.py from drf_extra_fields.fields import Base64ImageField from rest_framework import serializers class ProfileSerializer(serializers.Serializer): email = serializers.CharField(required=False, allow_null=True) image = Base64ImageField(required=False, allow_null=True, max_length=None, use_url=True) # views.py def get_as_base64(url: AnyStr): if url is None: return None, None full_name = url.split("/")[-1] my_base = base64.b64encode(requests.get(url).content) return my_base, full_name def do_profile_update(profile: Dict): b64_image, file_name = get_as_base64(profile.get("url")) if b64_image and file_name: *_, file_ext = file_name.split(".") b64_image = f"data:image/{file_ext};base64,{b64_image.decode('utf-8')}" build_dict = { "email": profile.get("email"), "image": b64_image, } serializer = ProfileSerializer(data=build_dict) serializer.is_valid() # returns True # serializer.validated_data = {'email': 'test@example.org', 'image': <SimpleUploadedFile: 11735acf-6d96-4c62-9e6a-8ebb7f7ea509.jpg (image/jpeg)>} Profile.objects.filter(pk=pk).update(**serializer.validated_data) # This saves the *name* of the image to the database, but no image file I understand that a ImageField is basically a CharField, and I can see the name of the image in the database, but the image isn't written to the server.

Django S3 : Saving images doesn't work when calling serializer
I need to create an API to upload images on a website. I've already created in my models the save method to upload and resize images. It's working correctly by the django administration page. Unfortunately, when I use my serializer, the image does not save. Here is my model : models.py class Shop(models.Model): name = models.CharField(max_length=255) category = models.ForeignKey(ShopCategory, on_delete=models.SET_NULL, null=True, blank=True) description = models.TextField(blank=True, null=True) path = models.CharField(max_length=255, unique=True, null=True, blank=True) mustBeLogged = models.BooleanField(default=False) deliveries = models.FloatField(validators=[MinValueValidator(0),], default=7) message = models.TextField(null=True, blank=True) banner = models.ImageField(null=True, blank=True) def save(self, *args, **kwargs): try: """If we want to update""" this = Shop.objects.get(id=self.id) if self.banner: image_resize(self.banner, 300, 300) if this.banner != self.banner: this.banner.delete(save=False) else: this.banner.delete(save=False) except: """If we want to create a shop""" if self.banner: image_resize(self.banner, 300, 300) super().save(*args, **kwargs) def delete(self): self.banner.delete(save=False) super().delete() def __str__(self): return self.name banner is the imagefield that I have to save. Here is my serializer : serializers.py class ShopSerializer(serializers.ModelSerializer): links = serializers.SerializerMethodField() isOwner = serializers.SerializerMethodField() banner = serializers.SerializerMethodField() class Meta: model = Shop fields = '__all__' def get_links(self, obj): links = Link.objects.filter(shop=obj) data = LinkSerializer(links, many=True).data return data def get_banner(self, obj): """Get a link for the banner""" if obj.banner: url = f"https://myurl/v1/images/{obj.banner.name}" return url def get_isOwner(self, obj): … -
How to add product to cart on a page with many products in E-commerce Vue.js / Django Rest Framework?
I am building an e-commerce website with Vue.js and Django Rest Framework. I have a page with all the latest products, that works well and fetches all the data. I can visit the details of each product and add them to the cart (on each product's page). The problem is that I don't know and can't get to add those products from the general products page where there are multiple products and get the number of products of each one of them. I created a dynamic Id for number input, but when I try to use it it says "Cannot read property 'value' of null" I understand that the number of products should be related to each one of the products, but I can't seem to understand how to do that. To sum things up: How can I add products to the cart on a page with multiple products fetched via v-for? Thank you! This is my Vue.js Products page code: <template> <div id="productapp"> <!-- Intro Section --> <div class="row" id="home__screen"> <div class="col-lg-12 text-center align-self-center decorator__spacing"> <h1 class="mt-5 mb-4 text-white">Conoce nuestros productos</h1> <button type="button" class="btn btn-light pl-3 pr-3 fw-bold main__text__color">VER MÁS</button> </div> </div> <!-- About Section --> <div class="w-100 bg-white …
