Is Django 4 async faster then sync queries
I'm trying to do an exercise to evaluate the value of upgrading to Django 4 and changing some of the queryset to async. To try and assess performance, I've created a couple of views to assess sync vs async and at present I can't see any performance improvement when communicating with the database. Firstly, I intentionally created two inefficient views where the db is supposed to be hit hard: Sync def some_validation(post): """Check that number of tags > 5""" return post.tags.count() > 5 @api_view(["GET"]) def posts_with_tags(request): start_time = time.monotonic() posts = [] for post in Post.objects.all(): tags = [] for tag in post.tags.all(): tags.append(tag.name) post_data = { "id": post.id, "title": post.title, "content": post.content, "tags": tags, "validation_passed": some_validation(post), } posts.append(post_data) end_time = time.monotonic() time_elapsed = end_time - start_time return Response( { "posts": posts, "time_elapsed": time_elapsed, "num_queries": len(connection.queries), } ) Async async def some_validation_async(post): """Check that number of tags > 5""" return await post.tags.acount() > 5 @api_view(["GET"]) async def posts_with_tags_async(request): start_time = time.monotonic() post_data = [] async for post in Post.objects.all(): post_tags = [] async for tag in post.tags.all(): post_tags.append(tag.name) validation_res = await some_validation_async(post) post_data.append( { "id": post.id, "title": post.title, "content": post.content, "tags": post_tags, "validation_passed": validation_res, } ) end_time = time.monotonic() time_elapsed … -

In wagtail, how to include a ForeignKey for a snippet with a panel that lets you add/create new items?
Having a snippet "Scientist" and another snippet "Country". When editing Scientist, it shows a dropdown with all the countries. I'm trying to find a way to also show an "Add new" so the editor can add a new country directly from the Scientist's change form. Currently, they should first go to the Country snippet panel, add a new one, and then go back to the Scientist and create the new one. Here's a simplification of the code: class Country(models.Model): name = models.CharField( _("name"), max_length=25, ) panels = [ FieldPanel("name"), ] class Scientist(DraftStateMixin, RevisionMixin, ClusterableModel): name = models.CharField(_("name"), max_length=25) country = models.ForeignKey( Country, on_delete=models.PROTECT, ) panels = [ FieldPanel("name"), FieldPanel("country"), ] Scientist is extending ClusterableModel because in the real code there's another field that's a ParentalManyToManyField. Using Wagtail 5.0. Thanks a lot! -

How to get fields name from Django QuerySet, even when it's an empty set?
A cool binding between Django and Pandas is the ability to construct a DataFrame directly from a QuerySet using: queryset = models.A.objects.filter(...).annotate(...) frame = pd.DataFrame(queryset.values()) Which wonderfully works as long as there is at least one record returned by the QuerySet. Acting at the QuerySet level is interesting because there we can have the benefit of all annotations as well as native columns. But this method will return a totally empty DataFrame (without columns defined), let's say from something like: queryset = models.A.objects.filter(id__lt=0).annotate(...) frame = pd.DataFrame(queryset.values()) The DataFrame is totally empty: Empty DataFrame Columns: [] Index: [] While we want something like instead: Empty DataFrame Columns: ["id", "key", "prop1", ...] Index: [] Where columns names are preserved in order to get this frame able to merge with another frames seamlessly. The pandas way to do this is to force columns names at the DataFrame creation using the columns switch. queryset = models.A.objects.filter(...) frame = pd.DataFrame(queryset.values(), columns=queryset.get_fields()) Unfortunately it seems that this get_fields or similar is not implemented or obvious at the first glance for the QuerySet object. I already know that I can fetch column names from a QuerySet that exists() using this dirty one: frame = pd.DataFrame( queryset.values(), columns=queryset[0].__dict__.keys() … -
