Re: Best way to run a shell script, using input value from Django?

[Alex Heyden]

So, a lot of this doesn't have much to do with Django, but I'm not sure how
familiar you are with web server best practices in general, so apologies if
some of this is remedial for you.

If something takes two minutes to finish, you don't want it being handled
on the request handler itself. Split the job off into a separate worker,
then return *something* to the user. Ideally, that something will allow the
user to continue polling for job updates.

Sounds simple, but the details can be obnoxious. First, you have to figure
out how to track the job. Personally, I prefer to not have to watch a
worker directly. I'd rather watch the results come through. For example, if
your script takes two minutes because it's updating a few thousand items
somewhere, I'd rather watch the items change by OS mtime or auto_now on a
model or whatever makes sense in your context. That means less complexity
in my workers and less complexity in my database. You might not be so
lucky. If one user can kick off a dozen or so of these jobs, and they only
do one thing each, you're probably going to have to track Celery workers
individually by sending to the user a job identifier and storing them in
your database with a foreign key out to your User model. Regardless of how
you decide to do it, the job of the initial request handler is to take care
of this piece of the puzzle: how am I going to track this, kick off the
job, send the tracking information to the user.

The script itself is probably pretty easy. A Celery worker using subprocess
from the standard library will be sufficient, with maybe a little bit
watching stdout to figure out how far along the job is if you need to. Have
the worker write its progress to the database row associated with the job,
or use celery-progress if you'd rather use someone else's implementation of
that idea.

In your UI, you'll want some sort of AJAX loop so the user can watch the
job go. This is usually pretty simple too: just an endpoint that queries
the job's status as recorded in the database and returns it without fanfare.

You probably don't want to automatically delete the database entry for the
job once its done, because you don't know if the user was there to see the
end of it. Save that for a periodic task or a response to the user
acknowledging the end of the job run.

Re: Are distance lookups available for MySQL or not?

https://mariadb.com/kb/en/library/mysqlmariadb-spatial-support-matrix/ seems

there's no listing for dwithin.  so while there might be support for mysql,

No module named context_processors

[Larry Martell]

I am having an odd interment problem. I have an app which is deployed
at 30 different sites. At one site only, and only intermittently, user
will get the error 'No module named context_processors'.

It may happen on a page that was previously accessed with no error and
upon refreshing the same page it will come up fine. It will not occur
for months, then happen a few times in one day.

The app is deployed with nginx and uwsgi.

Here is a typical traceback:

As I said it's intermittent. Anyone have any ideas on what it could be
and/or how to debug it?

Best way to run a shell script, using input value from Django?

[Chris Robinson]

Hello, 

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

Lets say I have a simple terminal based shell script (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

Are distance lookups available for MySQL or not?

[Clara Daia]

Hello, everybody

I am using Django 2.1 with MariaDB 10.3.
I have been trying to get the 'dwithin' lookup to work on a PointField, but 
I keep getting the following error:

  ...
  File 
"/usr/local/lib/python3.6/site-packages/django/contrib/gis/db/models/lookups.py"
, line 74, in get_rhs_op
return connection.ops.gis_operators[self.lookup_name]
KeyError: 'dwithin'

(To be more precise, I am using this filter backend from a library 
,
 
which generates the lookup for me.)

Looking at the docs, I get conflicting info:

* this section 

 says "Availability: 
PostGIS, Oracle, SpatiaLite, PGRaster (Native)", implying 'not available on 
MySQL'
* this other section 

 says 
MySQL support was added on Django 2.0

I could switch to PostgreSQL as a last resort, but maybe I'm just 
forgetting some configuration? Are the distance lookups available for MySQL 
or not?

Best regards,

Clara

Installing and using django registration – backends

[Yuval Bachrach]

Installing and using django registration – backends

The package is installed (pip) and migration is clean. Next steps at the
documents: Adding to urls at urlpatterns but I get error messages (details
below). So I am stacked at the very beginning. As a Django beginner, I
would be happy to get some help.

The issues are with “backaends” that exists on the file system (with the
required content) but Django can’t find it



*Details:*

Ø  The urls added:

urlpatterns = [

url(r'^accounts/',
include('django_registration.backends.activation.urls')),

url(r'^accounts/', include('django.contrib.auth.urls')),

.

.

]

o   In here there is an error message (from runserver) ended with:

  File "", line 965, in _find_and_load_unlocked

ModuleNotFoundError: No module named 'django_registration.backends'



Ø  Commenting out the first url out of the two makes the error go away

Ø  Adding (inside url.py prior to urlpattern declaration):

from django_registration import backends

is resulted with the following error message:

ImportError: cannot import name 'backends' from 'django_registration'
(C:\Users\yuval\OneDrive\pythonWorkDir\django\tutor1\ybsite\django_registration\__init__.py)

(I did not think this line is to be added but wanted to see the
response…). I commented it out.



Ø  This is the case both when in settings.py INSTALLED_APPS I have or don’t
have the following:

 'django_registration',   # <= This one is OK

Ø  Trying to add

 'django_registration.backends',

 #   <= This one is NOT OK : error message:

oduleNotFoundError: No module named 'django_registration.backends'

(I did not think this line is to be added but wanted to see the
response…). I commented it out.



So now I don’t have an error message but also not having Django
registration ready to use…

Re: OneToOneField value must be a model instance, not a value?

OneToOneField value must be a model instance, not a value?

[regtech]

Hello everyone!
I am a junior who is first using OneToOneField, I found that the value which is 
giving to the field only could be a instance of the related model, can't be a 
value of the field which is specifed by the "to_field" ( else django will raise 
excption ).

In the other word, "to_field" does not make effect, django performing 
OneToOneField use PK.
I feel incomprehension and it makes me trouble on working.
Thanks!

cmd from where you are trying to start the server. You must see some error 
there. May be pasting the screenshot of that error might be helpful to 
indicate what is wrong here. 
See the terminal error and try to resolve it first. I guess there should be 
some import error or migration error or something else. Please do check 
first

Re: Error

[Kuber Sodari]

Hmm, I suspect your issue is with queryset there since it says Matching 
Query Doesn't exist. This error always tend to say you that your django 
orm query is not proper, it has certain fields or style that you can not 
perform in the way you have written. First of all, please check if your 
variables values on your queryset 
place = Chapter.objects.get(course__course_name=course_name, slug=slug)
you can't make the query with None values as you have defaulted on your 
method *def chapter(request, course_name=None, slug=None): *
Thus, my guess would be because of these variable values you are getting 
that error. You should have some values there instead of None or else it 
will always have that error.

And another thing I was wondering, why are you not using django 2.0 :D ?

What would you like us to do? Personally I won't  / can't do anything with
the code you sent because I don't know what error you got nor do I know the
environment in which you run that code. I sure wish my crystal ball ball
was working.

If I ran that code I would get an error reporting unknown name Chapters.

So give us enough so that we could at least get started. If you got a trace
back please copy and paste the entire traceback.

If you included an attachment it did not come through.

Re: DetailView only works with slug and primary key?

[Andréas Kühne]

Hi,

The DetailView has a method "get_object" that you can override and use to
return the object via any source you choose.
You can also override the pk_url_kwarg or slug_url_kwarg properties on the
DetailView to retrieve the information from the url in any way you want.

Regards,

Andréas

Re: How to deploy Django Python Webapp with Windows10?

[Joel Mathew]

Also why are you attempting to deploy it online from your laptop. An online
application needs to be.. well, online, all the time. That's the function
of a server. You dont normally deploy from a laptop, unless you have a
specific need to do so. If it's for a client, definitely a big no-no. Use a
lightweight Linux distro like Debian, and install a server on it
(apache/nginx), and run django with mod_wsgi_express.

If you dont know or dont care on installing your own server, just go with a
built in solution like heroku.

Sincerely yours,

Re: How to deploy Django Python Webapp with Windows10?

[Joel Mathew]

Windows 10 is not designed to be a server. What is your issue in deploying
in Ubuntu or Debian?

Sincerely yours,

I guess you not using a frontend framework like reactJs or AngularJs. So i 
would suggest you look into AJAX. this could be done easily using jQuery's 
ajax function

Get the list of related objects in Django

[Tessnim Zrayga]

I have 3 models:

class Node(models.Model):
ID = models.DecimalField(max_digits=19, decimal_places=10)
name = models.CharField(default='node', max_length=32)
connexion = models.CharField(max_length=255)
# Many2one fields | Foreign keys:
firm = models.ForeignKey('firme.Firme', on_delete=models.CASCADE, 
null=True, blank=True)

class ScheduledAction(models.Model):
date = models.DateTimeField(default=datetime.now, blank=True)
firm = models.ForeignKey('firme.Firme', on_delete=models.CASCADE, 
null=True, blank=True)
node_ids = models.ManyToManyField(Node)

I want in ScheduledAction form to show, for a selected firm, the list of 
its related nodes. Normally I should do this by get:

class ScheduledActionForm(forms.ModelForm):
date = forms.DateTimeField()
firm = forms.ModelChoiceField(queryset=Firme.objects.all())
node_ids = 
forms.ModelMultipleChoiceField(queryset=Node.objects.get(firm_id=firm.id), 
widget=forms.CheckboxSelectMultiple)

class Meta:
model = ScheduledAction
fields = [
'date',
'firm',
'node_ids'
]

But I got this error:

AttributeError: 'ModelChoiceField' object has no attribute 'id'

How can I fix this?
