unicode_to_repr - depricated package of "rest_framework"
While upgrading Django 2.2 to 3.2.9 I've encountered a couple of dependencies that were deprecated, of which "unicode_to_repr" is the one I couldnt find sufficient information about, neither on its usage or of its substitutes. Can someone advise how to proceed? Is there a valid replacement for this module? Thank you, Lior. -

Django queryset annotate if SearchQuery is found in field
I have a model like this: (With a trigger in Postgres that populates vector_column) class Article(models.Model) content = models.TextField() vector_column = SearchVectorField(null=True) I query this model like this: Article.objects.filter( Q( vector_column=SearchQuery( "cat", config="english", search_type="phrase" ) | vector_column=SearchQuery( "dog", config="english", search_type="phrase" ) ) ) So it will filter out all articles with "dog" and "cat" in the content. I've been trying to figure out how I can annotate the articles by if the word is found in the vector_column. I can not do two separate queries because, in reality, I have a lot more conditions in the query than this. The optimal output would be something like this: [ { "content": "cats", "words_found": ["cat"] }, { "content": "dogs", "words_found": ["dog"] }, { "content": "dogs and cats", "words_found": ["dog", "cat"] } ] -
Django ListView how to make query I need in class as I had it before in my function
I'm new at django and did my first project using book Eric Matthews python crash course, but now I'm trying do it better and change function that works perfectly into class, but can not get how to make it in Class the same query by filtering public and not public "topics" for users. Could somebody give me advice please how it works in classes? The function which is works perfectly and then the class I need worked like this function: def topics(request): """Provide list of topics.""" public_topics = Topic.objects.filter(public=True).order_by('date_added') if request.user.is_authenticated: private_topics = Topic.objects.filter(owner=request.user).order_by('date_added') topics = public_topics | private_topics else: topics = public_topics context = {'topics': topics} return render(request, 'learning_logs/topics.html', context) And there is the class I need that it worked like the previous function. Could you advice what should be in queryset with public, owner and request? class TopicsHome(ListView): model = Topic template_name = 'learning_logs/topics.html' context_object_name = 'topics' def get_queryset(self): return Topic.objects.filter(public=True).order_by('date_added') -
Why do localize template tag and USE_L10N sometimes produce different results?
According to Django docs, the localize template tag allows for more fine-grained control of localization in templates than the general USE_L10N = True setting. However, turning localize on doesn't always produce the same result as setting USE_L10N = True. For example, # USE_L10N = True in settings.py {% load l10n %} {{some_datetime_value|date}} # Date is shown and localized vs # USE_L10N = False in settings.py {% load l10n %} {% localize on %} {{some_datetime_value|date}} {% endlocalize %} # Date is shown and NOT localized Why are the two results different? And is there a way to make the localize tag localize correctly in those cases? -

How to correctly use Django defer() when CONCAT to large textfield
I have a textfield with lots of data (>400000 lines of text). I think this is the reason that my server sometimes suddenly denies service when many users append new text lines. I am using so far Item.objects.filter(pk=iitem.pk).update(html=Concat("html", Value(msg))) to append a new msg. But I think the problem is that beforehand I have to check some other fields of iitem, so I do iitem = IMPALitem.objects.get(pk=p["iibox"]). Am I correctly assuming, that this is where all the data (40MB) gets unnecessarily loaded from the DB (postgres) into memory!? Is changing the get to iitem = IMPALitem.objects.get(pk=p["iibox"]).defer("html") all I need to do? (Does the defer() need to go left/in-front-of the get()?)? -

How to prevent Django TestCase creating SQL table with prefixes?
I have started building TestCase for API which used Django Rest Framework. But the moment I started, I realized the database TestCase created included prefixes in my table. I know I can change the table name to be more Django-friently but I don't think it will work with my current MySQL setup. This is the error I got. django.db.utils.ProgrammingError: (1146, "Table 'test_db.foo' doesn't exist") And when I run with --keepdb, the table it created is api_foo, where api is where the models.py is stored Is there a way to prevent Django from renaming my table name at all? -
Django reverse foreign key constraint
I have 2 models, Asset and Trade. The Trade model has Asset linked by a foreign key, which allows null values depending on the status of the Trade. An Asset always needs to be linked to a Trade by the foreign key. An Asset can have many Trades, but a Trade can only have 1 Asset. The problem is that sometimes an Asset is created without a Trade, and this needs to fail because it then causes further errors as it shouldn't be possible. How can I ensure the reverse foreign key is never null for the Asset model, but keep the on_delete parameter as SET_NULL? class Trade(models.Model): status = models.CharField(max_length=10) asset = models.ForeignKey( Asset, on_delete=models.SET_NULL, blank=True, null=True, ) class Asset(models.Model): price = models.DecimalField(max_digits=16, decimal_places=2) -

How to automatically launch django web server by windows SYSTEM
I want to know if there's a way to have windows server 2019 automatically launch django's web server. I also want the launch to be performed at startup and by SYSTEM. I tried using batch scripts that launch manage.py from venv's python interpreter. When I launch the batch manually (i.e. double click) it works fine and dandy. But it appears that SYSTEM fails in running the script correctly when planning the task. I made SYSTEM launch another script at startup (a simple python script that creates a txt file from within its own venv) and it works. If the Django launch sceipt is launched by USER then it works. The problem is with the launching of django with SYSTEM. I've also tried streamlit and the result is the same. Do you have any Ideas? Sample batch script: cd path\of\managepyfile\ C:\path_to_venv\Scripts\python -m manage.py
