quote_from_bytes() expected bytes
Hi
I am using Django 4.0.4.
I am getting the TypeError quote_from_bytes() expected bytes when I save my
model after creating a task.
When I backspace, the create form is still there on the screen as if not
saved.
When I go to List View or Detail View, I find that everything went OK.
The error would be an inconvenience to a user.
The suggested solution from various quarters is to have get_absolute_url
right, but it is:
def get_absolute_url(self):
return (
reverse("internalcontrol:task_detail", kwargs={"pk": self.pk}),
)
The prior models also have the get_absolute_url like this and they work
normally.
What could be wrong?

Connection timeout error with Postgres
Hi, I am facing below connection timeout error while using Postgres as database for my Django application.

How to 301 redirect django url with multiple slashes on url path?
I am trying to figure out how to redirect properly some urls that contain multiple slashes and create a permanent 301 redirect whenever the slug changes. For example: A - https://example.org/category/subcategory/article-name-A B - https://example.org/category/subcategory/article-name-B I want to redirect the A to B. I tried the default redirects app from django but did not work with multiple slashes.

QuerySet Caching of ManyToMany fields
Hi All, We've been working on improving the performance of our backend recently, and have started analyzing the database queries generated by Django more thoroughly. We quickly realized that we were mis-using our ManyToMany fields. We had assumed that the results of accessing an M2M field would be cached like accessing a ForeignKey would. https://docs.djangoproject.com/en/dev/topics/db/queries/#one-to-many-relationships This is definitely not the case, ManyToMany fields are not cached. We went down a bit of a rabbit hole, including this StackOverflow (https://stackoverflow.com/questions/8316437/does-django-cache-related-foreignkey-and-manytomanyfield-fields-once-theyre-acc/71887338#71887338) After a lot of digging through the docs, I finally realized that they were already trying to make that clear: https://docs.djangoproject.com/en/dev/topics/db/optimization/#understand-cached-attributes Have others run into this mistake? Seems like either a feature request or a documentation update would be a good idea. Russell -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: simple command line ./manage.py shell puzzle
The script should quietly exist without error. I actually have a longer script that is the real workhorse. I just made this tiny one to showcase the issue. I can past import datetime ; [datetime for e in [1, 2]] into a regular Python3 shell as well as the Django shell and all is fine. The problem I think has something to do with how I inject it into the Django shell via "< test". cs On Thursday, April 21, 2022 at 12:18:04 PM UTC-5 larry.mart...@gmail.com wrote: > On Thu, Apr 21, 2022 at 1:06 PM cseb...@gmail.com > wrote: > > > > Why does this fail?... > > > > % echo "import datetime ; [datetime for e in [1, 2]]" > test > > > > % ./manage.py shell < test > > > > Traceback (most recent call last): > > File "./manage.py", line 8, in > > django.core.management.execute_from_command_line(sys.argv) > > File > "/usr/lib/python3/dist-packages/django/core/management/__init__.py", line > 381, in execute_from_command_line > > utility.execute() > > File > "/usr/lib/python3/dist-packages/django/core/management/__init__.py", line > 375, in execute > > self.fetch_command(subcommand).run_from_argv(self.argv) > > File "/usr/lib/python3/dist-packages/django/core/management/base.py", > line 323, in run_from_argv > > self.execute(*args, **cmd_options) > > File "/usr/lib/python3/dist-packages/django/core/management/base.py", > line 364, in execute > > output = self.handle(*args, **options) > > File > "/usr/lib/python3/dist-packages/django/core/management/commands/shell.py", > line 92, in handle > > exec(sys.stdin.read()) > > File "", line 1, in > > File "", line 1, in > > NameError: name 'datetime' is not defined > > What do you expect to happen? > -- You received this message because you are subscribed to the Google Groups "Django users" group.
