Re: Do queries made instantiating a form not show up in db.connection.queries?

[Jonathan Berger]

Thank you!

I was looking at the value of 'connection.queries' before rendering the
form.

Do queries made instantiating a form not show up in db.connection.queries?

[Jonathan Berger]

Hi Django Users,

I'm a moderate-level user of Django and trying to determine if I've found a
bug.

Per the db and model FAQ
:
expected behavior is that 'connection.queries' should contain a list of all
SQL queries made by an app.

I'm finding actual behavior for a Form subclass that has a
ModelMultipleChoiceField with a default queryset, does not add that query
to 'connection.queries'. This violates expected behavior.

Am I misunderstanding something or is this a bug?

Thanks,
Jonathan

Re: Using django on kubernetes

[Dan Davis]

Thanks, would you say that running Minikube is the best way to learn 
Kubernetes at a significant level, or would you recommend a small 
Virtualbox/vagrant setup that really is a multi-node Kubernetes?   I don't 
really have enough cores and memory for the later anyway, but I could just 
start-up workloads on Amazon KCS or GCP to learn, if Minikube is not enough.

Re: race condition on post multiple files to the same folder

[Simon Charette]

Hello there,

I think you just hit #29890[0], a bug present in Django in 2.0+ and fixed 
in Django 2.1.3
which should be released today[1].

Simply updating to 2.1.3 when it's released should address your issue.

Cheers,
Simon

race condition on post multiple files to the same folder

[Han Hu]

Here is my model definition

class Item(models.Model):
name = models.CharField(max_length=256)


def item_id_path(instance, filename):
return '{}/{}'.format(instance.item.id, filename)


# Create your models here.
class File(models.Model):
file = models.FileField(upload_to=item_id_path)
timestamp = models.DateTimeField(auto_now_add=True)
item = models.ForeignKey(Item, on_delete=models.CASCADE)

def __str__(self):
return self.file.name


The application posts multiples file that belong to the same item. But I 
run into race condition in making directories. My server stores all the 
related files in a separate folder (named by the item id) together.

In django/core/files/storage.py _save method it checks the existence of 
uploading directory. When multiple files for the same item are uploaded the 
first request checks the existence of the directory and is going to create 
one, then it switches to the second file upload. It also finds that the 
directory doesn't exist yet and it is going to do the same directory 
creation. The second file upload will fail because the first file upload 
has already created the folder. It fails at the last line of the following 
code snippet in storage.py.

def _save(self, name, content):
full_path = self.path(name)

# Create any intermediate directories that do not exist.
directory = os.path.dirname(full_path)
if not os.path.exists(directory):
try:
if self.directory_permissions_mode is not None:
# os.makedirs applies the global umask, so we reset it,
# for consistency with file_permissions_mode behavior.
old_umask = os.umask(0)
try:
os.makedirs(directory, self.directory_permissions_mode)
finally:
os.umask(old_umask)
else:
os.makedirs(directory)


what approach can I take to avoid this race condition? 

I guess changing the source code from os.makedirs(directory) to 
os.makedirs(directory, exist_ok=True) could work.
