Re: Installing and using django registration – backends

[Rahul Verma]

Can you try like ths
  urlpatterns = [
 # Other URL patterns ...
url(r'^accounts/', include('registration.backends.activation.urls')),
# More URL patterns ...
]
 By the way, this is the documentation of Django Registration ,Hopefully it
may help you.

Your Post model doesn't have any fields in it, just the two Managers. We can't 
see what model the fields are defined in, because your screenshot cuts that off.

Re: Installing and using django registration – backends

[Yuval Bachrach]

For the suggested link I get the following error message:
"ModuleNotFoundError: No module named 'registration'"
I think registration is the old name used at version 2.3.
 Instead of following the pdf I follow
https://django-registration.readthedocs.io/en/3.0/
(pdf is for an older version 2.3)
specifically
https://django-registration.readthedocs.io/en/3.0/quickstart.html is short
and describes the way to start and the urls to use... but, I am getting the
error message I have described.

Re: Are distance lookups available for MySQL or not?

[Clara Daia]

Hello, Jason

I appreciate your help, and I tried running the test with a MySQL container
but got the same error.
The MySQL spatial reference

does not have a'dwithin' entry or similar either.

I changed my query to

self.assertEqual(MyModel.objects.filter(
geopositionfield__distance_lt=(
Point(-25.427855, -49.279644),
0.00028321143293561684)
).count(), 1)

And it seems to have worked, both on the MySQL and the MariaDB containers.
I suppose there is limited support and the documentation should specify
which distance functions are available for MySQL. Do you think I should
file a ticket?

Best regards,

Clara

Shame on me, there is a table for that in the docs.

Mysql query which splits by '-' and matches against last index.
SELECT * from Employee WHERE substring_index(emp_number, '-', -1) = '111';

I cannot write endswith on a column like below:
Employee.objects.filter(emp_number__endswith='111').values('emp_number')

Deploying Django multi servers, 1 DB server

[Peter van der Does]

We currently have one app server, so deployment with migrations is easy,
but we're expanding to multiple app servers and one DB server.

How do people handle migrations? I understand you run migrations on one
server only. But how do you inform the other servers that migrations has
finished and they can start doing the next steps.

We're open to using any DevOps tool, Ansible, Puppet, Chef.
We don't do any form of CI, nor are we planning to do so in the near future.

If more details are needed let me know and I can provide them.

Re: Deploying Django multi servers, 1 DB server

[Christian Ledermann]

You will have to split migrations from code changes.
The migrated database will have to run with both old and new code.
You may have to split one migration into several to achieve this

Re: Best way to submit application cmd, then download a resulting file?

[PASCUAL Eric]

Hi Chris,


The problem you describe does not require Django at all to be solved.


WRT process parameter input, what you need here is a simple Web based UI with a 
basic form. Of course Django can do it, but if you don't need features such as 
the ORM, admin... you can implement it with a couple of lines using lighter 
frameworks (e.g. Tornado).


The point about monitoring  the process requires first that this process is 
able to provide a feedback on demand. On *nix systems, this can be done by 
handling one of the USR signals (e.g. SIG_USR1) and of course implementing the 
process in non blocking mode (to be able to handle the USR signal while 
computing).


How the feedback is returned to the end user is another story. Real time 
feedback in Web apps is preferably done using Web sockets (rather than polling 
periodically the server from JS code on the UI page). Who will push the 
feedback on the socket ? It can be the computation process itself, supposing 
appropriate connection information are passed to it. But it is cleaner to 
separate concerns and isolate this in a monitoring specialized layer, 
communicating with the computation process via Unix sockets for instance or 
capturing its stdout and grabbing dedicated messages in it (e.g. a message like 
"PROGRESS: 30"). One option for implementing this monitor is using job Queues, 
as provided in the multiprocess part of Python standard lib. One you also use 
Celery, RQ or any job queue framework, but chances are that this would be 
overkill (especially Celery). RQ is maybe a good choice here, since very 
lightweight and having RabbitMQ as its only dependency.


Hope this helps


Regards

Eric

Subject: Best way to submit application cmd, then download a resulting file?

Hello,

I'm going to attempt to generalize my question to make this easier to answer.

Lets say I have a simple terminal based application (e.g. multiply_by_two) that 
takes a number argument, then multiplies that number by 2, and returns the 
result into a result.txt file.

I would enter something like this:
multiply_by_two -n 6

The -n flag asks what number I would like to multiply by 2. The result of this 
would be a result.txt, containing the number 12 inside.


What I would like to do is develop a simple Djano application that contains a 
text field allowing me to input the number 6, then click "Submit."

This job will start on the server by running my custom multiply_by_two 
application with my input parameter (6), but when the job is finished and the 
result.txt is available, the browser will automatically download the file.

To make this a tad bit more complex, lets say that the job takes 2 minutes to 
run. What would be the best way to monitor the job? Maybe I accidentally close 
the window.

Not looking for anyone to solve this, I'm just new to Django and want to know 
if someone can give me any pointers on where to start. Are there any apps 
existing that will help me not need to write everything from scratch, 
especially if 'monitoring' is needed? Would Celery be ideal for this?

Thanks for any input!

Regards,
Chris

Filter by sum of filtered related objects?

[Dustin Wyatt]

Given the following models:


class Transaction(models.Model):
  amount = models.IntegerField()
  date = models.DateField()
  terms = models.ForeignKey('Terms')


class Terms(models.Model):
  name = models.CharField(max_length=100)
  timezone = models.CharField(max_length=50)


I need to annotate Terms with the sum of the related Transaction.amount's 
where the Transaction.date is between two dates and what those two dates 
are varies by Terms.timezone.

Possible?

Hacking attempts

[Mike Dewhirst]

I'm no expert and I suspect things are working as designed but I'm 
getting multiple admin emails from a production site reporting attempts 
to access wsgi.py


So my question is: Can I change the name of wsgi.py so the hackers get 
401 errors and maybe go away?


The emails have subject lines like ...

[Django] ERROR (EXTERNAL IP): Invalid HTTP_HOST header: 
'43.211.128.177'. You may need to add u'43.211.128.177' to ALLOWED_HOSTS.


ALLOWED_HOSTS is tied down to exactly the website domain.

Thanks

Mike

Yes! You can do that. You've to just hop over to the wsgi.py setting part.
