Seeking Guidance on Migrating Django Project to Golang and Finding Equivalent to reversion Library
We are currently migrating a project from Python (Django) to Golang (Gin). In our application, we use the reversion library. Is there an equivalent in Golang? If not, how can we implement the migration of this functionality in Golang? Perhaps someone has encountered this and can give me advice. @reversion.register() class DocumentRecommendationMedia(models.Model): document = models.ForeignKey("Document.Document", on_delete=models.CASCADE) file = models.FileField(upload_to=settings.DOCUMENT_RECOMMENDATION_PATH) file_name = models.CharField(max_length=100) class Meta: db_table = "document_recommendation_media" @reversion.register(fields=("recommendation", "date", "media_files")) class DocumentRecommendation(ArchivableModel): document = models.ForeignKey("Document.Document", on_delete=models.CASCADE) recommendation = models.TextField(null=True, blank=True) date = models.DateTimeField(default=timezone.now) media_files = models.ManyToManyField(DocumentRecommendationMedia, blank=True) class Meta: db_table = "document_recommendation" I am seeking possible implementation options for reversion in Golang. -
Get object by id of OneToOne related object in DRF
I have Progress model wich relates with Deck model by OneToOne relation. I want to get Progress object from API by passing deck_id to 'http://localhost/api/v1/progress/deck_id/' endpoint. How I can do this? Or may be should I consider other implementations of retrieving Progress object? Also I want all CRUD functions with this model. class Deck(models.Model): name = models.CharField(max_length=70) owner = models.ForeignKey( CustomUser, on_delete=models.CASCADE, related_name='decks', ) class Progress(models.Model): deck = models.OneToOneField(Deck) progress = models.JSONField( null=True ) class ProgressViewSet(viewsets.ModelViewSet): queryset = Progress.objects.all() serializer_class = ProgressSerializer permission_classes = (OwnerOrAdminProgress,) lookup_field = 'id' http_method_names = ['get', 'post', 'patch', 'delete'] class ProgressSerializer(serializers.ModelSerializer): progress = serializers.JSONField() class Meta: model = Progress fields = ('id', 'deck', 'progress') router_v1 = routers.DefaultRouter() router_v1.register('v1/decks', DeckViewSet, basename='decks') router_v1.register('v1/progress', ProgressViewSet, basename='progress') urlpatterns = [ path('', include(router_v1.urls)), ] -

Passing Django Usernames to Streamlit
I'm working on a project using Django for user authentication and Streamlit for the front end. I'm struggling to fetch the authenticated user's information from Django and pass it to my Streamlit app. How can I efficiently retrieve user data from Django and securely transfer it to Streamlit? Any guidance or code examples for this integration would be appreciated. Thanks! Attempted to establish communication between Django and Streamlit by creating an endpoint in Django to fetch user information. I expected to retrieve the authenticated user's data from Django and then use an HTTP request in Streamlit to fetch this data from the Django endpoint. However, I encountered difficulties in properly implementing this communication and handling the data transfer securely between the two platforms. Also Tried to Use Javascript To Fetch On Screen Infomration -

How can I avoid this Numpy ArrayMemoryError when using scikit-learn's DictVectorizer on my data?
I'm getting a numpy.core._exceptions._ArrayMemoryError when I try to use scikit-learn's DictVectorizer on my data. I'm using Python 3.9 in PyCharm on Windows 10, and my system has 64 GB of RAM. I'm pre-processing text data for training a Keras POS-tagger. The data starts in this format, with lists of tokens for each sentence: sentences = [['Eorum', 'fines', 'Nervii', 'attingebant'], ['ait', 'enim'], ['scriptum', 'est', 'enim', 'in', 'lege', 'Mosi'], ...] I then use the following function to extract useful features from the dataset: def get_word_features(words, word_index): """Return a dictionary of important word features for an individual word in the context of its sentence""" word = words[word_index] return { 'word': word, 'sent_len': len(words), 'word_len': len(word), 'first_word': word_index == 0, 'last_word': word_index == len(words) - 1, 'start_letter': word[0], 'start_letters-2': word[:2], 'start_letters-3': word[:3], 'end_letter': word[-1], 'end_letters-2': word[-2:], 'end_letters-3': word[-3:], 'previous_word': '' if word_index == 0 else words[word_index - 1], 'following_word': '' if word_index == len(words) - 1 else words[word_index + 1] } word_dicts = list() for sentence in sentences: for index, token in enumerate(sentence): word_dicts.append(get_word_features(sentence, index)) In this format the data isn't very large. It seems to only be about 3.3 MB. Next I setup DictVectorizer, fit it to the data, and try to transform … -

How to really completely completely remove pgadmin4 web version from ubuntu (nothing works)
I have tried this: sudo apt -y remove pgadmin4 sudo apt -y autoremove pgadmin4* It does not work I have tried this: pip3 uninstall pgadmin4 it does not work while it says "successfully removed" it is not! The problem is that I have forgotten the password so uninstalling and installing does not help because it does not give me a chance to reenter the new data: So I have gone to env/lib/python3.10/site-packages/pgadmin4/config_local.py LOG_FILE = '/var/log/pgadmin4/pgadmin4.log' SQLITE_PATH = '/var/lib/pgadmin4/pgadmin4.db' SESSION_DB_PATH = '/var/lib/pgadmin4/sessions' STORAGE_DIR = '/var/lib/pgadmin4/storage' SERVER_MODE = True and removed the stored sessions, the config_loca.py file and still does not work because when I run this: python3 venv/lib/python3.10/site-packages/pgadmin4/setup.py it does not pop me up to enter email and password like the first time I installed it but it just reads: pgadmin4 application initialisation I am going insane about it.

Hi Everyone! Happy New Year I was trying to deploy my vite react application in vercel or netlify. I hosted it's backend part in render, Now backend is working, but when i hosted in frontend, the request URL change to hosted URL because I used vite proxy to use shortcut URL but it's not working in devlopment, Example of my vite cconfig // https://vitejs.dev/config/ export default defineConfig({ plugins: [ VitePWA(manifestForPlugin), react(), ], server: { proxy: { "/api": { target: "https://sample__.onrender.com", changeOrigin: true, secure: false, rewrite: (path) => path.replace("/api", ""), }, }, }, build: { proxy: { "/api": { target: "https://sample__.onrender.com/", changeOrigin: true, secure: false, rewrite: (path) => path.replace("/api", ""), } } } }); so when i call api my url is like: api/auth/login/ so in localhost, it will became, localhost:8000/auth/login/ but when i did it from dev server of netlify or vercel it become like vercel/netlify url/api/auth/login/ In localhost my backend is runnning in 8000 and frontend is runningin 5173 -

How to deploy a remote production server using Jenkins?
We currently have our Dev server and Jenkins server on the same Cloud instance1. OS user: djDev Jenkins install owner: jenkins We are able to deploy our Django application build on this same instance1 using Jenkins and application is accessible fine but the files are deployed in /var/lib/jenkins folder. This is because Jenkins configuration is pointing to /var/lib/jenkins Is this possible to deploy the application in OS user folder, like /home/djDev/djApp While we try to modify the above folders and keep this instance1 for both Dev and Jenkins server, we need to deploy a production server on a remote cloud instance2 and deploy the application in a desired OS user´s using the same Jenkins server. (ex: user: djProd and /home/djProd/djApp) Our plan is to deploy the Production server as soon as automated tests are passed on Dev. server. Our repository is in Github. Please let me if there is any recommended steps to achieve the above deployment especially for Django application and also when users are different on each instance? Best Regards -

Django 5 and Python 3.12.1 send_mail fails with SSL error
I have a working application using Django 3.2.6 and Python 3.9.6. I'm trying to upgrade to Django 5 and Python 3.12.1. So far, I've managed to track down and fix a number of problems caused by various changes and deprecations but this one has had me stumped for several days.

I've spent many hours fruitlessly searching for a solution. I've looked at the source for the django smtp module and the python ssl module and in desperation even the cpython _ssl module, but I can't figure out … -

Unsaved model instances to related filters in tests for django 5.0
In Django 5 "passing unsaved model instances to related filters is no longer allowed" (https://docs.djangoproject.com/en/5.0/releases/5.0/). Basically before I had this method (only relevant code shown): def make_payload(user, nonce, exclude_groups=None): exclude_groups = set(exclude_groups or []) relevant_groups = Group.objects.filter(internal_only=False).order_by("internal_name") filter_q = Q(user=user) & ~Q(pk__in=exclude_groups) add_groups = relevant_groups.filter(filter_q).values_list("internal_name", flat=True) ... And tested it using this test method (only relevant code shown): def test_builds_payload_not_activated(self): user = accounts.tests.factories.UserFactory.build(email_verified=False) payload = utils.make_payload(user, "nonce-nce") ... Now obviously the instance as not been saved as it's a unit and not an integration test. This leads to relevant_groups.filter(filter_q) failing with ValueError: Model instances passed to related filters must be saved. Basically I've no idea how to fix the test as the code is still working in a real environment. Ideas welcome. -

Integrate webpack template with Django
I'm working on a Django project, and I'm trying to integrate an HTML template built with npm using webpack into the Django project. I'm curious about the necessity of these {% static %} tags in the HTML templates. Issue: When visiting a URL like /view/user, static files are being loaded from /view/user instead of the expected /static. This happens because I am not adding the {% static %} template tag in the html templates.

# firstly, I split my data target = 'member_casual' X_train = train.drop(target, axis=1) y_train = train[target] # Then, transformed my numerical and categorical columns cat_trans = Pipeline([("imputer", SimpleImputer(strategy="most_frequent")),('encoder',OneHotEncoder(handle_unknown="ignore", drop="first", sparse=False))]) num_trans = Pipeline([("imputer", SimpleImputer(strategy="mean")),("scaler", MinMaxScaler())]) preprocessor = ColumnTransformer(transformers=[('num', num_trans, num),('cat', cat_trans, cat)]) pipeline = Pipeline([('preprocessor', preprocessor)]) # then this next code gave me errors pipe_fit = pipeline.fit(x_train) A key error and value error: A given column is not a column of the dataframe
