How to make Django translations accessible from Javascript?
How do you make all of the Django app locale/<lang>/django.po translations accessible from Javascript so you can dynamically translate text in Javascript widgets? According to these docs you need to add a URL pattern to your urls.py like: urlpatterns += i18n_patterns( path("jsi18n/", JavaScriptCatalog.as_view(packages=['myapp1', 'myapp2', ....]), name="javascript-catalog"), and then in your base template's <head> add the includes: <script type="text/javascript" src="{% url 'admin:jsi18n' %}"></script> <script type="text/javascript" src="{% url 'javascript-catalog' %}"></script> I've done this, and I have Japanese locale/ja/django.po (and their compiled .mo) files for every app in my project. However, when I access the URLs generated by {% url 'admin:jsi18n' %} (/admin/jsi18n/) and {% url 'javascript-catalog' %} (/ja/jsi18n/) it doesn't contain any of my custom translations. Why is this? What step in the docs am I missing preventing my translations from being accessible in the Javascript catalog? -
CORS problem with django running on GCP compute engine code-server
I am working on a Django project. For that, I work both in my personal laptop as well on a remote code-server instance (VS Code Remote) running on GCP compute engine. I run code-remote on https://dev.myweb.com (fake url) and when running the django server via python manage.py runserver in port 8000 the built in proxy allows me to connect via https://dev.myweb.com/proxy/8000 I can get to the first page (base.html) without problem (no forms or request in that page). But when I click on login (which would bring a POST request, that I think is the problem?), I get a error like this: Forbidden (403) CSRF verification failed. Request aborted. Help Reason given for failure: Origin checking failed - https://dev.myweb.com does not match any trusted origins. In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django’s CSRF mechanism has not been used correctly. For POST forms, you need to ensure: Your browser is accepting cookies. The view function passes a request to the template’s render method. In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL. If you are not using CsrfViewMiddleware, then you … -
Signal receivers must accept keyword arguments (**kwargs) when using pre_delete signal in Django
I am trying to make a destructor-similar signal in django to be called before any children of the class Base are deleted. The reason is that I need to change something on another models's field when this is deleted as part of cleaning up, and I want this to run when for example deleting the instance from Admin. I have this in my models.py: @receiver(pre_delete, sender = Base) def delete_shot_script(sender, instance, **kwargs): print("Calling the destructor") do_something... I am getting the error ValueError: Signal receivers must accept keyword arguments (**kwargs), why? Is the approach valid otherwise? I have tried adding **kwargs, but the error seems to persist. -
Django - PropertyFilterSet - How to filter on a property when the property refers to a model
How can I filter on a model's property with django_property_filter package given the following Django models: # models.py from django.db import models class Manager(models.Model): name = models.CharField(max_length=35) class Plan(models.Model): name = models.CharField(max_length=35) manager = models.ForeignKey(Manager, on_delete=models.CASCADE) class Member: name = models.CharField(max_length=35) plan = models.ForeignKey(Plan, on_delete=models.CASCADE) @property def manager(self): return self.plan.manager # filters.py from django_property_filter import PropertyFilterSet class Meta: model = Member fields = [] class MemberFilter(PropertyFilterSet): manager = ???( field_name='manager', ) I tried the PropertyMultipleChoiceFilter and PropertyChoiceFilter with no success.

Extract a subtree from the tree structure returned by DecisionTreeRegressor (recursive & iterative versions)
Given A starting root node and a certain depth, I want to extract the subtree from the scikit-learn's DecisionTreeRegressor tree.

Get the ID of the current logged-in user into a standalone script in Django?
I have a standalone script in Django that receives messages from a Redis server. Each incoming message is coded with a topic. Users of the site will indicate which topics they are interested in receiving messages for. Their preferences are stored in a database as True or False for each topic. I’m currently stuck trying to figure out a way to obtain the currently logged in user’s id so that I can reference their topic preferences against each incoming message’s topic. I can’t figure out how to get the ID of the currently logged in user into the standalone script. Does anyone know how to do this? I've been stuck on this for days so any insights would be greatly appreciated! -
Bringing a Django Model to a HTML Table
I am very new to Django and I am working on my first training project. I want to document every month a set of meters (water, electricity, and more) and I want to see those meters in a html table like: Nov 2023 Dec 2023 Jan 2024 Meter 1 500 510 Meter 2 1000 1300 Meter 3 100 110 120 I am using 4 models in models.py: model metertype -> electricity, water, and other types of meters model meter -> name/description of the meter model readingdate -> date of the reading, normally last day of month model readingsvalue -> the values I read from the meters from django.db import models class meterType(models.Model): meterType = models.CharField(max_length=100) class meter(models.Model): meterName = models.CharField(max_length=100) meterType = models.ForeignKey( meterType, on_delete=models.CASCADE) class readingDate(models.Model): date = models.DateField() class readingsValue(models.Model): readingsValue = models.DecimalField(max_digits=10, decimal_places=2) meter = models.ForeignKey(Zaehler, on_delete=models.CASCADE) readingDate = models.ForeignKey(Ablesedatum, on_delete=models.CASCADE) After this done (it seams to work in the admin area).

Django ArrayField. How to save JSON in array from Django Admin?
I have an ArrayField in my model. My model looks like this: class UserProfile(UUIDPrimaryKeyModel): canceled_plans_data = ArrayField(models.JSONField(), default=list, blank=True) When I append python dict in this field, it gets saved and later fetched easily. But as soon as I open this model in Django Admin and without any change in any field of this model, click on save button, it gives me error. Error is following: Item 1 in the array did not validate: Enter a valid JSON. Item 2 in the array did not validate: Enter a valid JSON. I am not sure what's wrong. I have just shown this field in Admin Model like this: class UserProfileAdmin(admin.ModelAdmin): fields = ('user', 'canceled_plans_data',) How I can fix this problem? -

In Celery, how to use autoretry and run some code after the last retry?
In Celery, I want to take advantage of autoretry_for and retry_backoff arguments. But I also want to report the exceptions manually to Sentry, to add a scope with the level of the error. I know I can add the scope with something like this: except Exception as e: try: raise self.retry(exc=e) except MaxRetriesExceededError: with sentry_sdk.push_scope() as scope: scope.level = 'critical' sentry_sdk.capture_exception(e) But if I do that, the exponential backoff does not work. Is there any other way to add the scope of the error without having to implement the backoff by myself? -

ValueError: Expected n_neighbors <= n_samples (mismatch between the number of neighbors specified and the number of samples in the data)
I want to implement multi-view spectral clustering. The supervised_multi_view_spectral_clustering function takes multiple views of feature matrices (X_views), a target variable (y), and clustering parameters, and performs spectral clustering on the concatenated features. The second function finds the optimal number of clusters based on silhouette scores when given a list of mixed representations. The final part of the code uses these functions to determine the optimal number of clusters and performs multi-view spectral clustering on the provided data (mixed_representation_all). By design, the input latent_representations_train_nmf is a dictionary of numpy array, whereas y is a multi-variate dataframe. The error indicates that there is a mismatch between the number of neighbors specified and the number of samples in the data. This is despite ensuring that n_neighbors is always less than or equal to the number of samples. Code: from sklearn.preprocessing import LabelEncoder from sklearn.cluster import SpectralClustering from sklearn.metrics import accuracy_score def supervised_multi_view_spectral_clustering(X_views, y, n_clusters, affinity='nearest_neighbors', max_neighbors=10): # Check if y is already encoded if isinstance(y.iloc[0, 0], str): # Assuming the first element of the dataframe is a string if not encoded # Encode labels if they are not numerical label_encoder = LabelEncoder() y_encoded = label_encoder.fit_transform(y) else: # Use the provided encoded y directly … -

The field in the model is as follow: price = MoneyField( default=0.0, decimal_places=2, max_digits=12, default_currency="EUR", verbose_name=_("Price [EUR]"), ) Version info django 4.2.8 djmoney 3.4.1 django-tables2 2.7.0 python 3.10.6 Related information https://django-tables2.readthedocs.io/en/latest/pages/column-headers-and-footers.html#adding-column-footers Django-tables2 column total Django-tables2 footer sum of computed column values -
taking picture from the django admin panel to a website with zip
There will be a field in the Django admin panel, I will select zip from this field. there will be about 60 to 70 images in the zip file. I want to be able to display these images as slides on my website, but I haven't found a solution. I've tried multiple solutions, but none of them have been successful, so I can't share the codes. -
