Django: How do I check for duplicates before bulk_create (when defining the object)?
I would like to define an object and check if it is a duplicate before creating it,as shown below. if data['title'] in videos: I'm hoping I can determine it this way. How can I determine duplicates? videos = [] throughs = [] for datas in files: for data in datas: tags = data["tags"].split() tag_pks = list( set([Tag.objects.get_or_create(name=tag)[0].pk for tag in tags]) ) #Around here, we want to make sure that the list called videos already contains data['title']. video = Video( title=data["title"], thumbnail_url=data["thumbnail_url"], preview_url=data["preview_url"], embed_url=data["embed_url"], embed_source=data["embed_source"], duration=data["duration"], published_at=data["published_at"], ) for tag_pk in tag_pks: throughs.append( Video.tags.through(video_id=video.pk, tag_id=tag_pk) ) videos.append(video) Video.objects.bulk_create(videos) Video.tags.through.objects.bulk_create(throughs) -
django redirect to other page and auto login to that page
Is there a way to redirect to other page and automatically log into that page? So it's like I make django webpage with login and create link to facebook. When user clicks to facebook link, it should automatically login to his facebook page. Of course, I will have his facebook username and password on db I used to create the website. Is this possible? Basically, I am trying to create interface page on django with link to several different webpage and make user access to his page by simply logon to this interface page alone. -

How do I fix pagination when there is a GET filter from the URL?
In the main product browse page (www.url.com/works), pagination works well (displays 10 items at a time) and the URL becomes www.url.com/works/?page=2 In the same view, the works can be filtered by category (i.e. www.url.com/works/?collection=Drawing). Since it using the same view, it is still paginating by 10, but if I click other pages, it loses the /?collection=Drawing and just goes back to being www.url.com/works/?page=2. How do I combine them to be something like www.url.com/works/?collection=Drawing&page=2 ? Thank you! views.py class ProductListView(ListView): model = Product template_name = "products/product_all.html" paginate_by = 10 def get_queryset(self, *args, **kwargs): sold = ProductPurchase.objects.filter( refunded=False ).values_list('product_id') qs = super(ProductListView, self).get_queryset(**kwargs) qs = qs.filter(for_sale=True, test_check=False).exclude(id__in=sold).order_by('-timestamp') categoryfilter = self.request.GET.get("collection") if categoryfilter: qs = qs.filter( Q(category__name__icontains=categoryfilter) ) query = self.request.GET.get("q") if query: tags = Tag.objects.filter( slug=query ).values_list('products') qs = qs.filter( Q(title__icontains=query) | Q(description__icontains=query) | Q(material__icontains=query) | Q(id__in=tags) ).order_by("title") return MyFilterSet(data=self.request.GET, queryset=qs).filter() -
how to configure Postgres to work with pytest
I am using django for my backend and pytest to handle my tests. I switched my project db from sqlite3 to postgres, everything works just fine except for the tests, for some reason all of my them are failing. before switching I was able to access my db during my tests with the following line: pytestmark = pytest.mark.django_db but now after using Postgres as my db I get this error on all of my tests UndefinedTable The above exception was the direct cause of the following exception: request = <SubRequest '_django_db_marker' for <Function test_logged_user_saved_recipes_url_reverse>> @pytest.fixture(autouse=True) def _django_db_marker(request): """Implement the django_db marker, internal to pytest-django.

Use of serializer class in other frameworks
Why isn't there a serializer class just like in DRF Djnago in node, express , laravel or RoR?? Is it just on python we need serialization? In every other framework, are data saved as json in database? I dont think so. Can someone explain this? For eg in DRF we have something like this: class Leadserializer(serializers.ModelSerializer): class Meta: model = Lead fields = '__all__' Here this serializer class serializes all the fields of Lead model while calling a get api. It brings out the complex queryset to json format in api response. Shouldnt the same thing be happening in all other frameworks as well?? -

Using Django/Postgres to store binary data in a memory efficient manor
Context I have a Django project, and inside of this project, I have a database model with a field of type models.BinaryField(max_length=50000000, default=b'0') Problem When the server is requested to query for this binary data, even though there are never more than 1-2 concurrent requests, I am reaching the ram limits of my server using io.BytesIO, along with stream.seek({index}), and stream.close()(I use the term stream very loosely, as I am simply referring to seeking and closing a stream of bytes here). Question Is it possible that I need to implement the way I am storing this binary data differently? Solutions that I have tried that didn't work Would splitting it up into chunks of smaller sizes be computationally more efficient for the RAM of the server? When I attempted this, I discovered that chunking up the file into smaller chunks and relating them with a many-to-one relationship was extremely taxing as far as overhead on the database. -

I don't understand how to use the django-dynamic-formset plugin
I am using the Django Dynamic Formset However, I have not found a documentation for noobs who are just starting out, I feel that they already take many things for granted and do not go step by step. I have several doubts: In point 5 of the page, it mentions that I must write jquery.formset.js in my MEDIA_ROOT and I must include the jQuery library if my MEDIA_ROOT, but how will I do that if mine is like this MEDIA_ROOT = os.path.join (BASE_DIR, ' photos') in point 4 of the plugin documentation it says this prefix: '{{formset.prefix}}' which means prefix here -

Wrong decimal round to first 2 digits of amounts in python 3.7 and Django
Let there be 3 Django fields: INPUT = models.DecimalField(max_digits=20, decimal_places=3, default=0) RESULT = models.DecimalField(max_digits=20, decimal_places=3, default=0) RATE = models.DecimalField(max_digits=12, decimal_places=5, default=1) RATE is always Decimal('1.00000'). I want to have RESULT = INPUT * RATE and since the source is either from database, either from APIs, I use: RESULT = Decimal(INPUT) * Decimal(RATE) I do not know why, but in some cases (≈ 2%) I end with the numbers you see in the following table. There is a round to the first 2 digits. Do you know what could cause that? I do not see anything in the code that could do that and I am clueless. Both columns should be equal.

Django verbose logging for bad request
I am relatively new to django. I recently deployed my application on a web server, and I find it very hard to debug issue. I am getting 400 Http status code for some of my requests and not sure why. I am trying to increase the level of logs in order to find the root cause for it. However, the output of the logs in not very informative. I am using this configuration for logging (DEBUG is enabled): logging.config.dictConfig({ 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'console': { 'format': '%(name)-12s %(levelname)-8s %(message)s' }, 'file': { 'format': '%(asctime)s %(name)-12s %(levelname)-8s %(message)s' } }, 'handlers': { 'console': { 'class': 'logging.StreamHandler', 'formatter': 'console' }, 'file': { 'level': 'DEBUG', 'class': 'logging.FileHandler', 'formatter': 'file', 'filename': '/var/log/django/debug.log' } }, 'loggers': { '': { 'level': 'DEBUG', 'handlers': ['console', 'file'] } } }) This is the output that I am getting in the logs: 2021-11-18 16:18:59,667 django.request WARNING Bad Request: /create How can increase the verbosity of the logs to be more informative? -
Django url kwargs in templates
Previously we have been accessing kwargs in Django templates with {{view.kwargs.kwarh_name}}. However, it has been to my surprise that this is not working in my django 3.2.4+ Has it been removed, is there any issue with the line above? Note: Kwargs here I mean something like below: Given a function as below: def GetSomething(request, code): return render(request, "some template here") Now, the urlpatterns would be something like, import GetSomething from .views app_name = "some_app_name_here" urlpattern = [ path("link/<int:code>/", GetSomething, name="some_cool_name") #http:localhost/link/12345/ ] Now in HTML/Django templates or Jinja2(whichever you use), accessing this code would be via {{ view.kwargs.code }} But it so happens that this is not working for me in Django 3.2, any reasons?? Hope I was very clear! -
Django DurationField just for HH:MM never needing seconds?
I have a DurationField in my DB and trying to use this in ModelForm` with the purpose of keeping track of days if any, and only hours and minutes. I do not need seconds at all.

In my shell, I am getting a timdelta object such as datetime.timedelta(seconds=105) If anybody has any guidance as to how to accomplish this would be greatly appreciated! -

Apply a migration to Django Flatpage model
I would like to use the modeltranslation package in a Django application that uses the flatpages app. I installed both, followed the model translation docs, and created a translation.py file, which I put in the main app (where all the global stuff lies), as I can't put it directly in the flat pages app (Django code is a requirement and is not committed to VCS). # django/main/translation.py from modeltranslation.translator import translator, TranslationOptions from django.contrib.flatpages.models import FlatPage class FlatPageTranslationOptions(TranslationOptions): fields = ('title', 'content') translator.register(FlatPage, FlatPageTranslationOptions) Then I ran python manage.py makemigrations, and it created a migration file in the flatpages app /usr/local/lib/python3.8/site-packages/django/contrib/flatpages/migrations/0002_auto_20211118_1558.py. It would be again in the Django code, so I tried to simply move it to the main app at django/main/migrations/0002_flatpages_translations.py (there is already an unrelated 0001_initial.py migration, which has no dependencies): from django.db import migrations, models class Migration(migrations.Migration): dependencies = [ ('flatpages', '0001_initial'), ] operations = [ migrations.AddField( model_name='flatpage', name='content_en', field=models.TextField(blank=True, null=True, verbose_name='content'), ), migrations.AddField( model_name='flatpage', name='content_fr', field=models.TextField(blank=True, null=True, verbose_name='content'), ), migrations.AddField( model_name='flatpage', name='title_en', field=models.CharField(max_length=200, null=True, verbose_name='title'), ), migrations.AddField( model_name='flatpage', name='title_fr', field=models.CharField(max_length=200, null=True, verbose_name='title'), ), ] And... when I finally try to run the migration (python manage.py migrate), I got this error: CommandError: Conflicting migrations detected; multiple leaf … -

Change available options in select but don't change selected one
I wan't to create Django/JavaScript mechanism that will enable me to change form select data based on other selected fields. For example let's say I have two select fields, I change the first one, then the function is triggered in Django and new template is loaded to html select element (I am using Ajax for that). This works fine, but the problem is when I will choose element 1 and then I want element 2 to also be able to change element1, the first option is reseted. I was trying to solve this by remembering the selected field and then loading it in but it then triggers element 2 and it, won't work. Any help will be appreciated :)
