Re: Help deciding ORM VS raw SQL trade-off in Complex scenario

[eric paul]

According to your scenario an accounting system is a more complex system
that requires high performance. It can be written in any language but as
the system grows some programming languages will experience performance
issues python being one of them take a case like Dropbox which was
originally written in python but because of python speeds and data handling
limitations it led the team to introduce other languages (Go, Rust) . Since
you've decided to go with Django then it's best you use raw queries and
concurrency etc inorder to achieve high performance.It also comes down to
your hardware and code practices . Take a look at the Django ledger repo an
accounting system. About the API you can explore Graphql.

efficiency . I won't recommend to use Raw queries if you don't know what

Hi Django User Group Admins,

I hope this email finds you well.

I'm writing this to discuss the recent influx of spam emails in our 
group. As we know, this group is a great resource for Django developers 
to learn, share, and collaborate. However, in the past few months, we've 
seen an increase in emails that are unrelated to Django, such as job 
postings and promotional materials.


I understand that some people may want to use the group to post job 
listings, but I believe that these emails are disruptive and detract 
from the purpose of the group. I've also noticed that some people are 
responding to these emails, which only encourages more spam.


I've been thinking about ways to address this issue, and I have a few 
ideas. One idea is to create a separate Google group for job postings. 
This would allow people who are looking for jobs to connect with each 
other, while keeping the Django_users group focused on Django-related 
content.


Another idea is to develop a Zapier + OpenAI plugin that can detect the 
type of email (sentiment analysis) and then mark it as spam or 
non-Django related, add automated reply and mute it. This would help to 
automatically filter out spam emails, so that they don't clutter up our 
group's inbox.


I'm not sure which of these ideas is the best solution, but I wanted to 
get your thoughts on the matter. What do you think about the recent 
influx of spam emails in our group? Do you have any suggestions for how 
we can address this issue?


I'm happy to help in any way I can. Please let me know if you have any 
questions.


Thank you for your time.

With kind regards,
Abhishek Choudhury

Django dpahne prod

[Paul Haguet]

Hello everyone, I'am looking to deploy Django ASGI project in production.

This is the actual setup. Because Daphne is installed into the project 
python manage.py runserver use the asgi.py file instead of wsgi.

Si with this config the project run with asgi on port 8000 and wsgi on port 
5000.

Is there any big difference using

daphne -b 0.0.0.0 -p 8000 main.asgi:application

Instead of:
python manage.py runserver

[uwsgi]

uid = www-data
gid = www-data
socket  = 0.0.0.0:5000

for-readline= /srv/settings.env
env = %(_)
endfor  =

plugin  = python3
chdir   = /var/www/application
module  = main.wsgi:application

virtualenv  = /srv/env
daemonize   = /var/log/uwsgi/uwsgi_worker.log

attach-daemon = sh -c "cd /var/www/application/ ; source 
/srv/env/bin/activate && python manage.py runserver 0.0.0.0:8000"
attach-daemon = sh -c "cd /var/www/application/ ; source

Re: Django Admin

[Paul Kudla]

ok hope i am not adding to the confusion

I ran into this a while back

CSRF errors are usually (in my case anyways) triggered by apache SSL 
setup etc


if you are running Apache + SSL you need to make sure the certificates 
and the SNI ssl naming is setup correctly or the CSRF errors will 
trigger randomly.


of course the ssl cert has to match the site name

this config assumes APACHE + WSGI + SSL etc. and you are running 
multiple virtual sites under apache.


Also note the port 80 redirect (ie everything is directed to the SSL site)

if you are mixing ssl & non-ssl apache / django will get confused and 
trip the CSRF error as well.


relative apache config (httpd.conf):


SSLRandomSeed startup builtin
SSLRandomSeed connect builtin

SSLSessionCache memcache:localhost:11211  <<-- only if using memcache.



then my apache config for a site ?

admin.scom.ca ?


ServerName admin.scom.ca
ServerAlias admin.scom.ca
Redirect permanent / https://admin.scom.ca/



ServerName admin.scom.ca
ServerAlias admin.scom.ca
DocumentRoot /www/admin.scom.ca

Alias /media/ /www/admin.scom.ca/media/
Alias /static/ /www/admin.scom.ca/statics/
Alias /statics/ /www/admin.scom.ca/statics/


  Options FollowSymLinks

Hi there. I am fairly new to Django but have had previous success

Recently, if I attempt to access the admin page of a new Django app
it throws the CSRF error upon trying to log in!!!

I have attempted several ways to bypass this error including adding
allowed hosts but I cant seem to get past this issue.

Can someone please provide me with the definitive way of stopping
CSRF error when simply trying to access the admin part of Django? I
mean there are no post functions that really apply to this feature
so I cant understand the CSRF token.

I cant get past this issue which means I can never access the admin

Please help.

Re: Django call_command from Admin

[Paul Kudla]

you need to basically add a hook (save class) to your save model and 
process stuff along the way.


you will need to modify this example but it's how i update info when 
saving an scom email user for dovecot.


you can also override the admin class as well with something simaliar

Note :
super(EmailUsers, self).save(*args, **kwargs)  #Save the email changes

is extemely important as stuff will process but any field updates will 
not save without the above line..


example :


	def save(self, *args, **kwargs): #This will create an email account if 
nessesary.
		emailaddress = str(self.username) #Set the email address to see if we 
need to create the mailbox?
		emailpassword = str(self.password) #Set the password (used for check 
alias)


#prefill username/domain is blank
if self.domain == None or str(self.domain) == '' :
self.domain = self.username.split('@')[1]

if self.source == None or str(self.source) == '' :
self.source = self.username

if self.destination == None or str(self.destination) == '' :
self.destination = self.username




domain = str(self.domain)
send_settings = str(self.send_settings)
if self.send_settings == None :
send_settings = ''
self.send_settings = ''
dontupdate = self.dontupdate
self.dontupdate = False

#set dovecot directory & split user / domain
if self.username.split('@')[1] == 'preload.scom.ca' :
			self.home = '/data/dovecot/users/%s/%s' %( 
self.domain,self.destination.split('@')[0] )

else:
self.home = '/data/dovecot/users/%s/%s' %( 
self.domain,self.destination )

self.user = self.username.split('@')[0]

Re: django deploy on IIS

[Paul Kudla (SCOM.CA Internet Services Inc.)]

Ok please do not take this the wrong way .

this comes from 20+ years of experience of all the different platforms.

windows is good for microsoft office etc, they have kinda set the 
standard in day to day useage to run a business.


however 

production servers today are almost entirley on the unix side of the 
platforms.


although you could  try getting a windows IIS running (never tried and i 
do apologise for answering this thread saying that - i appreciate your 
frustration)


to get django to run on IIS (or consider windows apache would probably 
be better but at the end of the day ???)



i did try server 2019 + python3 + django + apache etc etc and gave up 
ended up putting the project on their freebsd router.



a lot of work would be spent when unix flavors are more suited to stuff 
like this.


at the end of the day windows is just not stable for multiple reasons.


too many lib issues to mention a few.

if you are running any kind of production server you really should look 
at a linux flavor (i use freebsd as it has several enhancements to the 
network layer)


Again not an answer but maybe it is !



Happy Saturday !!!

Why I love Django

Choosing a web framework is hard. Especially now when there are a lot of

Here is why I think that when building a large database-driven application, 
I would honestly pay to use Django.

Its a requirement if your application is using 1. a fronted framework,

Re: Static Code analysis and Security Scanning tools for Django Web Applications

[Paul Tiplady]

I also use safety  to scan for package 
vulnerabilities in the pipeline. This is similar to a repo-scanning app 
like Dependabot or Snyk.

Prospector is decent, although I found it preferable to use pre-commit 
 to wire up individual tools like bandit, black, 
./manage.py check, safety, flake8 -- that way I can run them as individual 
build jobs that run in parallel in the build pipeline, rather than one 
command invocation.

Using activate() to set the timezone in Model Admin

[Paul Tiplady]

I'd like to have my Admin site use a different default timezone than the 
rest of my django app.

I prefer the backend and API to operate in UTC, because this is a general 
good practice for geographically distributed teams. However admin users 
(based in a specific timezone) find this confusing, and would like to see 
their datetimes in a local timezone (say, Pacific Time).

The docs state that a local time can be set using 
activate(): 
https://docs.djangoproject.com/en/4.0/ref/utils/#django.utils.timezone.activate

Specifically: 
https://docs.djangoproject.com/en/4.0/topics/i18n/timezones/#default-current-time-zone
 
says "You should set the current time zone to the end user’s actual time 
zone with activate() 
.
 
Otherwise, the default time zone is used.".

Where should this be done to set the timezone only in the admin?

Simon Wilson has a suggestion to set this globally using 
Middleware: https://til.simonwillison.net/django/show-timezone-in-django-admin

I'm wondering if there's a better way that won't affect the TZ of non-admin 
requests. It seems that this should be configurable somewhere on the 
AdminSite.

Has anyone made this work specifically for the Django Admin?

Thanks!

Not necessarily. With Auth0, the IDP runs on Auth0's server.
You are responsible for storing ID tokens, access tokens, and refresh 
tokens in your app.
There are ways of doing this fairly securely, even with desktop apps or 
mobile

devices, where you don't have a secure backend.

If I understand this correctly, Google et al provide an MFA API for apps 
that want to handle
auth themselves, instead of going the OIDC/OAuth2/SAML route. They also 
provide standards

based protocols, like OIDC.

That's what I was hinting at above - adopting OIDC makes things easier 
than trying to bolt

on security (via some MFA API).

This is definitely a pain point. You can either open up a browser from 
the device, or on constrained
devices, use device flow (display a URL, user visits that URL on their 
laptop, device grabs confirmation
from the IDP that they did). Neither one is completely elegant, but 
opening a browser on a mobile

device is far less intrusive than you might think.

I'm not familiar with C.A.S. I don't have any clients that I know of 
using it, so I can't comment on it.

But the JWT token spec is now common, and is a standard. Also the SAML spec.
I see more OIDC, but also a lot of SAML.

It IS possible to use 2FA on Dovecot, but it would be better if Dovecot 
supported options by Plugins to control what supported 2FA options are 
supported in the CAPABILITIES string.  (Ongoing problem getting more 
power in the handles of 3rd party plugins for Dovecot, politics.. )


HOWEVER, there are many ways if you 'roll your own' dovecot, eg can 
apply patches to the build process.  We do this.


Having said that, yes.. especially in North America this push by 
insurance agents for 2FA, is driven by the RansomWare problems, and 
gives an insurance company a way out..


The only problem is, having looked at several of these insurance 
companies forms, it is almost as if a o365 sales person wrote the 
requirements.  And even IF you apply a 2FA, (eg a 2nd factor) you might 
find that the insurance documents will not accept anything other than 
what their legal department defined as 2FA..


The biggest problem, is not the use of 2FA, it is making 2FA transparent 
and simple enough for end users to adopt.  End users don't want to mess 
with a second factor they have to add, or a hardware dongle, or giving 
their cel# out..


And the industry has to come together, otherwise you will quickly find 
out insurance companies ONLY accept 2FA from one or two closed source 
companies..


Which is why once again, I wish that Dovecot would take a leadership 
role in this, and allow more 3rd party plugins to be available to 
address this business need.


(Oh, on the side, there ARE some ways you actually do 2FA transparently, 
but of course the email client has to understand it.  But while you can 
do 'tricks' even in IMAP for 2FA, we need to think that the same method 
should work for ALL communication channels which utilize the same 
credentials, eg IMAP/SMTP/POP, even other things like caldav/carddav etc)

address of the server (not 127.0.0.1) and it needs to be accesable on 
your network to be able to find it.


best to try telneting to the server as a test to verify ip & ports are 
correct.


example :

telnet 192.168.0.2  8000  for example if you get 
a response then you are good to go.


ie

"telnet 192.168.0.2 8000"

Re: Django email | Gmail | Outlook

[Paul Kudla (SCOM.CA Internet Services Inc.)]

thanks for the hint on gmailapi

i figure they had something outlook has an azure server plugin (same idea)

just an fyi i was taking a more generalized approach to the issue

as an isp i have customers spanning several different providers needing 
a more generalized solution.


gmail, office, rogers, aol, yahoo etc etc etc

i generally use fetchmail to handle this but there is no oauth2 
avaliable yet and you still need a device key - aka manual setup


I am putting together a python program to handle this the main issue is 
getting prompted backwards in html on a new device / connection and 
busilding some sort of connect library per provider.


Afterwhich i save the device key in a local database for future use?

simply put from my research to date is oauth2 does the following

redirects to a
website link for a key

3. once on the website you need to say yes to some kind of auth

4. the website returns the key (which you probably should save)

5. from there (thus far research to date) normal python libs
will handle
emails thereafter as before.

other option is like with google where you need to signup for a
developer account (or something) that will generate a key for your
account & device at which point other emails to that, only good
for 15
devices ??

after that you have to pay?

just a heads up, other non-main stream providers (like myself) have
other devices in place for security and will not force customers to
migrate, maybe look for a local provider?

I will eventually handle oauth2 etc but only when forced to
(government
contracts etc)

My suggestion (if you are in unix) is to start up a postfix /

email server instance where you are in control of the protocol's

this way your in complete control of your emails in both

a bit of work but leaving things to the main stream providers isn't

Re: POS Printer

[Paul Kudla (SCOM.CA Internet Services Inc.)]

ok a few zillion requirements

You need something that will generate a pdf file and then send it to a 
printer / email etc


Basically Pillow libs needs to be installed to generate a pdf file

from there is is system dependant

if running linux / freebsd then i would write the pdf file into the /tmp 
folder (make sure you set the rights of /tmp to 777)


next to be able to print you will need ghostscript / cups

cups needs the printer to be on your network (NOT USB Preferably)

USB Can be made to work but requires a whole wack of printer setup on 
the stations.


also Report Lab (Pillow libs)

#PDF (Report Lab Stuff)
from reportlab.pdfgen import canvas
from reportlab.lib.units import inch
from reportlab.lib.pagesizes import letter, A4
from reportlab.lib import colors
from reportlab.graphics.shapes import *
from reportlab.platypus import SimpleDocTemplate, Image

from reportlab.lib.colors import PCMYKColor, PCMYKColorSep, Color, 
black, blue, red, orange



please understand that this is very rough approach

if you need more info a can send my django code if nessesary but is 
tailered to my system


fyi

Re: What do they mean, exactly

[Paul Kudla (SCOM.CA Internet Services Inc.)]

this occurs when manage does not detect any changes to your project

or if the project folders have lost sync.

I have run into this before lots of times.

this is based on djando 1.11 but should work moving forward in principal.

In general try the following :

syncdb :

No longer exists 

when creating the database tables do the following :

remove ALL migrations directories in app's

manage makemigrations  DO FOR ALL APPS

manage migrate --fake-initial

manage migrate

manage createsuperuser (optional)

When creating new apps __init__.py must exist

manage migrate --fake-initial  to create the table(s)



the above will not destroy any db tables etc but if you added a field 
that never got updated to the database you will probably need to reverse 
the table changes (in your model), then sort the migrations out as per 
above and then re-add the table entries


This can happen when syntax errors, migrations errors occured on the 
last run and it did not make it far enough to add the fields?


hope this helps.

Happy Saturday !!!

Re: OperationalError at /admin/login database or disk is full

[Paul Kudla (SCOM.CA Internet Services Inc.)]

ok i will assume you are running a flavor of unix aka linux, freebsd etc

/admin/login is a mount point but it depends on your hdd layout

for example depending on your hdd initalization


# df
Filesystem   SizeUsed 
Avail Capacity  Mounted on
zroot/ROOT/default   393G3.3G 
389G 1%/
devfs1.0K1.0K

389G 0%/var/tmp
zroot/tmp389G136K 
389G 0%/tmp
zroot/var/log389G1.4M 
389G 0%/var/log
zroot389G 96K 
389G 0%/zroot
zroot/var/mail   389G148K

zroot/usr/home   431G 42G 
389G10%/usr/home
zroot/var/crash  389G 96K 
389G 0%/var/crash


when you do s 'df' to list you hdd's it will give you the partition 
layouts and avaliable hdd space


if /admin/login is on it own partition then it probably has reduced size?

check that first

make sure you data base is running where there is plenty of space (ie /usr/)

otherwise post back your hdd layout

and do a

ps -axww

and return the process layouts

between the two you should be able to figure out where your database, 
dhango etc lives and go from there


keep in mind that default locations usually work but sometimes not 
pending how your system was formatted.

Is this because my SQLite database is full from other projects? Or

[Paul Tiplady]

You can deploy to Heroku, there's a free tier and it's very low maintenance.

https://devcenter.heroku.com/articles/deploying-python

I've had a free Django app running there that I set up almost 10 years ago 
without any work required to keep it up since then.

Heroku is somewhat expensive if you actually get enough traffic that you 
need to start paying them, but it's ideal for the MVP / proof-of-concept 
phase of a project. If you're price-conscious and want to scale up a bit 
more, you can rent a dedicated VM for $5/month (for example, Digital Ocean 
droplets https://www.digitalocean.com/pricing/) and that will get you a lot 
more capacity per $. That said, you may find that the convenience of Heroku 
is worth paying for.

I am using django with DRF and dj_rest_auth

[Manas Paul]

I have made my custom user model. The dj_rest_auth returning the response 
after successfull login 
{ "access_token":

I want the user object to have all the fields that I have defined. I could 
not get the way how I can achieve that.

another problem I am getting I can register the user but when I am trying 
to login it says I can't login with the credentials [ "Unable to log in

What will be best option

[Manas Paul]

I have been working on a project, where the project has a Model called 
Competition and under each completion I have a model called  Artwork ( in 
foreign key relationship). I am using DRF and the problem I am facing is 
each artwork has a field called approved ( boolean ) and I want to retrieve 
all the approved artwork under a competition detail view. 

How can I filter that data on Competition retrieve API view. I could not 
find any good example. Please help

Also I have been thinking about to make another api which will filter the 
artwork only based on the given competition id.

Please help me to find out the solution.

Re: HOW TO REDIRECT DIFFERENT CATEGORY OF USERS THROUGH LOGIN REDIRECT (two login redirects instead of one)

[Kuntal Paul]

Thank you for your response. I did this way and it was giving me a 405
error. I couldn't find my mistake. I was saving both of them as student and
as teacher separately from auth.user.
 Also, do I have to provide a separate temple for that view?

HOW TO REDIRECT DIFFERENT CATEGORY OF USERS THROUGH LOGIN REDIRECT (two login redirects instead of one)

[Kuntal Paul]

The *LOGIN_REDIRECT_URL*  only allowing to redirect to a particular profile 
page. But in scenarios like where there are *students* and *teachers*, both 
of them need their specific profile page after login. 

Using* LOGIN_REDIRECT_URL*, both the teachers and the students are getting 
redirected to the same profile ( in my case, both of them either entirely 
to teachers profile or entirely to students profile). 

How can I set *two login redirects instead of one*? I searched in the 
documentation, online videos, and everything but couldn't find such. Please 
help me with resources/codes/guide/etc from where I can learn from and 
implement. I'm pretty new to this and have tried whatever I know till now.

Django - Heavy Databse Usage

[Paul Onteri]

Let's say you are building a SAAS application system in which every user 
will use the database heavily, for example, a hospital management system. 
Should you have separate databases for each user? And how do you implement 
this in Django?

JSONField filter fails with TypeError: can only concatenate tuple (not "list") to tuple

[John-Paul Navarro]

The following fails with Django 2.2.6 but works with Django 1.11.x.

Did filter() of JSONfield change in 2.2.6 and the query needs to change, or 
could this be a bug?

Goal:
   Select model rows where the related AbstractService.EntityJSON contents 
“Capability" list includes the value 'data.transfer.nonstriped'
Given: EntityJSON field contains "Capability": ["data.transfer.striped", 
"data.transfer.nonstriped"],

Executing:
  objects = 
Endpoint.objects.filter(AbstractService__EntityJSON__Capability__contains=['data.transfer.nonstriped’])
  serializernonstriped = xdinfo_gridftpn_Serializer(objects, many=True)
  len(serializernonstriped.data)

Failes like this:

Collapsible elements in admin stopped working with latest release

[Paul Michalski]

I just upgraded from Django 2.1.3 to 2.2.3, at which point collapsible
elements in the admin interface stopped working. I’m using IE11, and in the
console I see the error “object doesn't support property or method
'matches'”, with a reference to line 35 of collapse.js in the admin
package. I did some research and I found that IE11 doesn’t support the
“matches” function, so I just modified the admin base template with a
polyfill to get things working on my machine. But the collapsible elements
were working fine with my old version of Django on IE11, so it looks like a
polyfill (or something) was removed in the most recent Django version. Does
anyone know what might have changed? If something was changed, I think this
is a bug – we shouldn’t have to modify the templates in the admin package
to use IE11.



This is my first post. Thanks for any comments or suggestions.

template {% url %} tag is giving server's absolute path

[Paul Lanza]

I have recently changed my django project (using A2 hosting) from fcgi to 
wsgi.  I have successfully gotten the project to work, but I am 
experiencing a minor caveat I am trying to solve.  Now, when I use the {% 
url %} tag in the templates to form a link, I get the absolute path of the 
server (the results still works but the link now looks more ugly).

For example, I might have this in my urls.py

url("^about_us/$", views.about_us, name="about_us")


Then in my template, I would have this

{% url "about_us" %}


In my development, the template will render the link "/about_us" so that 
when you click the link, it takes you to www.mysite.com/about_us.html

Now, in production, the template will render the link 
"/home/myproject/myproject/about_us" so that when you click the link, it 
takes you to www.mysite.com/home/myproject/myproject/about_us.html

How can I get my production template rendering of the url tag to replicate 
the development rendering of the url tag.

Thanks for any help!

Re: Django Channels - core.py error

[Paul Whipp]

I've just had trouble with exactly the same error. In my case I was 
building from the tutorial ChatConsumer with my own XChatConsumer and I 
hadn't referenced it in the routing.py. As a result the tutorial async chat 
consumer was receiving a scope that did not contain a room_name in its 
url_route kwargs. Very obscure! I think the channel gets closed by an error 
and then this 500 error comes up rather than anything helpful for the 
original error.

Handling multiple timezones in Django Admin

[Paul Tiplady]

Timezone handling in the Django admin is quite confusing when there are 
users in multiple timezones -- does anyone have a good way of handling this?

I'm using USE_TZ=True, TIME_ZONE='UTC', USE_I18N, USE_L10N. I have admin 
users in US/Pacific and US/Eastern.

When viewing a datetime field, users see the UTC time, with a note below 
saying "Note: You are 7 hours behind server time". This is better than 
nothing, but still quite sub-par for a 201x-era web UI. We really should be 
localizing the timezones in the browser to the user's own time zone, and 
submitting back to the app using TZ-aware timestamp strings. (It's possible 
to pull the TZ unambiguously from a modern 
browser: https://stackoverflow.com/a/37512371/37481).

Any suggestions for getting round this? I'm wondering if there's a good 
tz-aware datetime widget for the admin? Or perhaps a clean way of storing a 
User.time_zone config property that could be used to localize the admin 
cleanly.

Cheers,
Paul

Security Check in Django

[Jerrina Paul]

Hi,

We started migrating a java project to Django .Our present code we are 
using  different filters for security. Mainly we are checking below filters

·   Session hijacking check

·   XSS attach check

·   CSRF check

·   Path manipulation check(directory traversal attack)

·   Access controller check

When I go through Django security documents ,I come across CSRF ,Session 
and XSS security. I would like to know  remaining security checks are 
already implemented in Django or we need to add our own check condition. We 
are not using Django templates for GUI .If we are adding angularJS for GUI, 
do we need to handle XSS security separately .


Regards,

Jerrina

Re: In the Admin, Is it possible to make filters on foreign keys usable with lots of related objects?

[Paul Tiplady]

I've used that in a few admin pages, as far a I understand it just
restricts the allowed values for a model's foreignkey field when editing a
model instance. I don't see any way to use that to change how the
`list_filter` functions -- am I missing something?

Re: In the Admin, Is it possible to make filters on foreign keys usable with lots of related objects?

That's a pretty inflexible solution though; what if I want to filter on
multiple foreign keys, e.g. Tenant=Foo(id=1), Customer=Bar(id=200)?

Re: Newbie - Microservice in Django - Best place to start learning

[Paul Tiplady]

Assuming you're trying to build a REST API and not a HTML website, you 
should look at http://www.django-rest-framework.org/ as it provides a lot 
of djangonic convenience methods for building REST APIs with the Django ORM.

In the Admin, Is it possible to make filters on foreign keys usable with lots of related objects?

[Paul Tiplady]

Currently it's simple to configure a filter on a foreign key in the admin:

`list_filter = ['theforeignkeyfield']`

However in practice this is barely usable in most cases that I've 
encountered, since the admin uses RelatedFieldListFilter, which fetches the 
full list of objects from the DB and loads them into the browser. For any 
production site that either times out or makes the admin unusably slow, not 
to mention the UX is terrible as it inserts a list of all of the items into 
the filter bar that needs to be scrolled through.

I'm not sure if this is fixed in 2.0 (I haven't played with the new select2 
integration that was added), but is there a plugin / workaround to use 
something like django-autocomplete-light, or a `raw_id_field` type approach 
in pre-2.0?

InlineFormset Updating issues, after changing the value in the input

[Paul]

I have 2 models Product and Image:

class Image(models.Model):
product = models.ForeignKey(Product, related_name='images', on_delete=
models.CASCADE)
parent = models.ForeignKey('self', blank=True, null=True, 
verbose_name='original 
image', on_delete=models.CASCADE)
image = models.ImageField(upload_to=file_upload_to)
image_type = models.CharField(max_length=50)



parent is a Foreign Key to the original image

I use the Image Model in a formset:

ImageFormSet = inlineformset_factory(parent_model=Product, model=Image,
form=ImageModelForm, min_num=1, max_num=4, can_delete=True)



Steps:

Set the Product Form with the inlineformset for Image
Show and submit the creation form
save the original image(s)
after the original image is saved, create multiple image by cropping 
the original image, using a task
Edit/Update Form, show as image one of the cropped image (instead of 
original) by modifying(filter by image_type) the Formset queryset

An here appear the issue:

The {{form.id}} value in case of update, is the pk(id) of the cropped 
image, instead of the original image:





and when the image is updated, is replacing the cropped image in database 
instead of the original image, and the 'cropped' tasks after and insertion 
in database is wrong.

I tried to replace the value(using a custom widget) instead of the cropped 
image with the pk(id) of the original(parent_id).

but if I do, this, on updating/replacing an older image, the new replacing 
image, is ignored; the form submit with no errors, but the replace image is 
not replaced; the other new images are ok.

So I think is a mechanism that compares the value in the the input with 
what was passed to the form, and if doesn't correspond is jut ignoring.

Re: Issues with image.path being reported wrong causing failing of a Celery task

[Paul]

I did, is not celery related. 

The only thing, that maybe is influencing the path, is that the Image model 
is used in an inlineformset.

Issues with image.path being reported wrong causing failing of a Celery task

[Paul]

 

I have the following model:


class Image(models.Model): image = models.ImageField(upload_to=
file_upload_to)


I have a dynamic file_upload function:


def file_upload_to(instance, filename): 
  base = '_'.join([str(instance.item.pk), instance.item.slug])
  return os.path.join('accounts', base, 'item', base_2, 'images', filename)

and in a ModelForm:


class ImageModelForm(ModelForm) 
 def save(self, commit=True): 
  image_obj = super().save(commit=commit) 
  product_image__task.delay(image_obj.image.path, image_obj.image.name, 
image_obj.product_id) return image_obj



I tried also to wait for transaction:


transaction.on_commit( lambda: 
product_image_crop_task.delay(image_obj.image.path, image_obj.image.name, 
image_obj.product_id))



The file is saved properly in a path like:


media/account/12_blue/images/image_name.jpeg



The problem is that image_obj.image.path is not reporting the correct path, 
but this path:


media/image_name.jpeg


I use the image path, further passing it as an argument to a task, but 
because I received the wrong path, it will fail.


How can I fix this, and receive the correct path ?  I tried also using 
time.sleep(), nothing works, the path/location returned is wrong, even if 
is saved to the correct one.

ManytoMany Relation and Custom widget in Django

[Paul]

I have two models Category and Products.

- a Product can have multiple Categories 
- a Category can have multiple Products.
- Categories have a circular Foreign key, to itself.
- not all Categories have the same depth level

Example:

Category A
- Category A_1
- category A_2
- Category A_2_1
Category B
Category C
- Category C_1


class Product:
categories = models.ManyToManyField(Category)
name = models.CharField(max_length=255)

class Category:
categories = models.ForeignKey(self)
name = models.CharField(max_length=255)

As Form I use a ModelForm:

class ProductForm(ModelForm):



class Meta:
model = Product
fields = ['categories', 'name', 'short_description', 
'description']
widgets = {
'categories': MyWidget,
}

**What I want to achieve:**

I want to implement a conditional select (narow options):

1. Only top parent Categories(level 0 A,B,C) are available
2. The user select a parent Category.  If the parent has children a new 
Select box appear with his children(category level 1 A1,C1) 
3. The user select a level 1 Category (A1,C1). If the parent has children a 
new Select box appear with his children(level 2 A2)

- The process is repeated until no children are availavable(recursive), an 
user select the "smallest" category in the tree
- A new button is available for the user to add more categories and start 
the 1-3 process again
- I want to do the select,add new select using JavaScript
- On Form Submit I want to send only the last children categories


Options I thought:

1. Change the ManyToMany coresponding default Fields - looks like there are 
no good hooks and/or inheritance
2. Use a non-default custom Field instean of ManytoMany(like Charfield) - 
more complex on clean,saving Form
3. Change/Inherit the widget. My issues is how to send the data to the 
default Field on submit, and get/show it on edit 
 
I need some help as code and indication how to do this.

ManytoMany Relation and Custom widget in Django

[Paul]

I have two models Categories and Products.

A Product can have multiple Categories, a Category can have multiple 
Products.

The Categories have a circular Foreign key, to itself.

class Product:
categories = models.ManyToManyField(Category)
name = models.CharField(max_length=255)

class Category:
categories = models.ManyToManyField(Category)
name = models.CharField(max_length=255)

Not all Categories have the same depth level. A Category can have no 
children and a Category can have multiple grandchildren.

*What I want to achieve:*

When a user add/create a Product, only a select-box containing the parents 
will appear. 

After the parent is selected, if the parent has children another select 
will appear with that parent children. Also the possibility to add more 
categories.

When a user what to edit a product the select boxes for what was already 
chosen should be available.

*From where I start:*

I know that to ManyToMany relation corresponds a ModelMultipleChoiceField 
Field.

To a ModelMultipleChoiceField corresponds a SelectMultiple widget.

I thought of creating an widget that inherits from SelectMultiple and 
change the templates manipulating the get_context_data on the Widget.

But my problem is that in context I don't have (know to find) the parent 
relation inside categories. 

What are my options ?

Re: Django raising error - hostname doesnot match.

[Rahul Paul]

Thanks James for your suggestion. So according to you, I must use the 
domain name and not the IP address anymore in my request. Thanks again.

Re: Django raising error - hostname doesnot match.

In some place I wrote that "However the very same API is returning proper 
result with both --- IP address and domain name". I would like to correct 
hat this scenario is working when I am hitting the API from POSTMAN.

Django raising error - hostname doesnot match.

[Rahul Paul]

Hi, 

I am using requests package to send a post request to an API within my 
application.

I am using the request as : 

*requests.post("https://xx.xxx.xxx.xxx/my-admin/api/api2;, data=data)*

where "xx.xxx.xxx.xxx" is the IP of my server on which this API is hosted.

When I am trying to call this API from my application, django is raising 
an  exception as follows:

*SSLError: hostname 'xx.xxx.xxx.xxx' doesn't match 'xxx.com'*

But when I put the domain name in the request i.e. "xxx.com", it gives me 
proper result. Also when I put verify=False along with the request, my 
application gives me proper result even with IP addess in the request. 
However the very same API is returning proper result with both --- IP 
address and domain name.

My server has a CA signed certificate but the DNS have forward entry but 
doesnot have a PTR entry. I have also verified with digicert.com and found 
that when I am entering the domain name, it is giving proper IP address but 
when I am giving IP address, it is not able to resolve the domain name. 

This API was functioning working correctly with IP address when we had self 
signed certificate.

Also I am using nginx-gunicorn to run my application.

Please help me with understanding why this is happening and what are the 
best possible solutions for this problem.

Thanks in advance.

What is the role of __deepcopy__ in Python class and Django widget

[Paul]

 

First, I know how copy and deepcopy from copy module work for a list.


I'm interested the role of __deepcopy special method inside a class.


I need to create custom widgets in Django and I try to understand the 
python code behind.


class Widget(metaclass=MediaDefiningClass):

needs_multipart_form = False  # Determines does this widget need multipart 
form
is_localized = False
is_required = False
supports_microseconds = True  # for data and time values

def __init__(self, attrs=None):
if attrs is not None:
self.attrs = attrs.copy()
else:
self.attrs = {}

def __deepcopy__(self, memo):
obj = copy.copy(self)
obj.attrs = self.attrs.copy()
memo[id(self)] = obj
return obj

What is happening with *__deepcopy__* when I make an instance of Widget, or 
and instance of a subclass of Widget ? Looks like is making a shallow copy 
of attributes and the object itself , but what is the purpose ?

ManytoMany field in Django admin not appearing

[Paul]

 

I have a Product model, an Image Model and a Category Model.

A Product can have multiple Images(Foreign Key) and a Product can be in 
multiple Categories a Category can contain multiple Products.

A Category can have multiple subcategories(key to itself).


class Category(MetaData): 
 parent = models.ForeignKey('self', blank=True, null=True, verbose_name='parent 
category', on_delete=models.CASCADE) 

class ProductMetaData): 
  categories = models.ManyToManyField(Category) 

class ProductImage(models.Model):  
  product = models.ForeignKey(Product, related_name='image', on_delete=
models.CASCADE)



In Product Django Admin: 

class ProductDocumentInline(admin.TabularInline): 
 model = ProductDocument class ProductAdmin(MetaData):
 inlines = [ProductImageInline]
 fieldsets = (
 ('Product Data', {
 'fields': ('name', 'short_description', 'description')
 }),
 ('SEO', {
 'classes': ('collapse',),
 'fields': ('meta_title', 'meta_description', 'slug', 'canonical')
 }),
 ('MetaData', {
 'classes': ('collapse',),
 'fields': (('created_at', 'created_by'), ('updated_at', 'updated_by'))
 }),
 )
 readonly_fields = ('created_at', 'updated_at', 'created_by', 'updated_by')
 list_display = ('name', 'updated_at')
 ordering = ('-updated_at',)
 search_fields = ('name',)


admin.site.register(Product, ProductAdmin)
admin.site.register(ProductImage)



Issues:

   1. 
   
   If I don't customize fieldsets (grouped, ordered) the Categories appear 
   like default in the middle of the form. If there are customized as in my 
   example they don't appear.
   2. 
   
   If they don't appear Products without Categories can be created and I 
   don't want that. I want a product to have at least one category.
   3. 
   
   Now the inline Images appear below all Product fields. 
   
I want the Categories to appear first, then normal fields for 
Product(grouped,ordered), Images inline and at the end the SEO and metadata 
fields. How can this be done ?

Possible Bug Regarding model choices and form hidden input?

[Paul Kenjora]

Hi,

  When setting HiddenInput on a form widget for an integer model field with
choices, in tests I get 'X is not a valid choice' errors.  I'm guessing
it's the hidden input returning a STRING and the model expecting an INT.

  I have a model that has


*class Banner(models.Model):*

*  banner_x = models.PositiveIntegerField(blank=False, default=0,
choices=enumerate(BANNER_XS))*


And a form that has

*class BannerForm(forms.ModelForm):*

*  class Meta:*

*model = Banner*

*fields = ['banner_x']*

*  def __init__(self, *args, **kwargs):*

*kwargs['prefix'] = 'banner'*

*super(BannerForm, self).__init__(*args, **kwargs)*

*self.fields['banner_x'].widget = forms.HiddenInput()*


In my unit tests I always get the error:

*resp = self.client.post(**'/banner/, {*

*  'banner-banner_x':0,*


*}, follow=True)*

*banner_xSelect a valid
choice. 0 is not one of the available choices.*


Anyone else seeing this?  Works fine via browser, just unit tests are not
coming back right.

How Django inlineformsets works internally

[Paul]

 I have a form with two inline formsets.
. 

At the HTML level Django use the hidden fields for the formset management, 
and use the prefix to know which fields are related to a formset.

Also it has ids in the html id, to group like in a virtual form the fields.


 
 




On retrieve by default I get the path to the file in a paragraph and the 
inputs (html elements) are empty.



 Currently: 
Test 
Insieme/documents/sdsasa7

Change:





On Browse(upload a different file) Django knows to update the same record 
in the database. Similar for click on checkbox.


*How Django make the correlation between the paragraph that show the path, 
the html id of the element and what is in the database?*


I want to change the UI (make it dynamic with JavaScript, use button 
instead of checkbox) and I want to understand how the mechanism is working.

Django InlineFormset : Customize inputs and widget

[Paul]

I’m using inlineformsets for an Image Model in combination with a Product 
Model.


For the Image Model (using javascript):


1) a remove/delete button will be available to remove an image; the image 
can be remove not only on edit, but also on creation(the use upload the 
image, but before saving doesn’t like the image and removes it) 2) An add 
button, when the user clicks a new input and corresponding fields are added


By default the inlineformset code is like this:


Document: File 
type: Delete:


Using inputs I can do it with javascript, but things get a little more 
complicated for what I want to do:


The user should click on an image button a modal window will appear with 
the option to crop. 

Now the Upload button is in the modal window. The user is cropping, I 
select and save the coordinates with javascript, also show a cropped image 
(simulated using css).


How do I transfer all this mechanism to Django inputs so formsets can 
understand what I want to do ?

Implementation Advice: Categories and Product Specifications

[Paul]

 

I have Product and Categories. A product can be in multiple categories and 
off course a Category have multiple products.


The Categories can have Subcategories’ which can have Subcategories. I used 
a Category Model with a circular Foreign Key.


Each Product can have specifications/attributes based in which Categories 
is. 


So the specifications are of the products but depends on the Categories.


I can’t add the specifications as Products attributes because they depend 
on categories, and the user can change categories.


I can’t add them as attributes per Category because the value are/can be 
different for each product.


Also an attribute/specification can appear in multiple Categories.


I want also to search for a Product filtering by attributes.


I think I need a separate Attribute Model that is linked (foreign key) to 
both Product and Category.


Also a way of “protection” in case a Product change categories, a Product 
and/or a Category is deleted.


What is the optimal approach as flexibility and performance ?

Django: Form validation strange behaviour

[Paul]

 

I want to do file validation(size,type) on a field on inlineformset. 


class ProductDocumentModelForm(ModelForm): 

  class Meta: model = ProductDocument 
   fields = ['document'] 

  def clean_document(self): 
   file = self.cleaned_data['document'] 
   validate_file(file, 'document')



Because I want to use the same validation in multiple application I created 
a separate function.


def validate_file(file, for_model, max_size=5000): 
 if for_model == 'document': 
  max_size = FILE_MAX_DOC_SIZE 
 
 if file.size > max_size: 
  raise ValidationError('Please keep file size under {}. Current file size is 
{}' .format(filesizeformat(FILE_MAX_DOC_SIZE), filesizeformat(file.size)))



The file size validation works as intended but introduce a strange behavior.


If this validation is in place and is passed the "This field cannot be 
blank." default validation is triggered even if the fields are not empty.


Without the file size validation in place there are no issue even if the 
fields are empty.


I don't understand what is the cause.

Django - Best option to check file types, even fake or without extensions

[Paul]

 

I'm trying to validate mime types of files uploaded with a predefined list 
of validate mime types. 


I need to do the check the file in the buffer before save, even if they are 
faked or no extensions.



1. python own  mimetypes package seems to "guess" only base on extension


2. magic-python looks ok, but has OS dependencies because is using UNIX 
libmagic.

 I had a lot of trouble with it on Windows 64 bit, and even after I fixed 
the dependencies error other issue appears and it couldn't identify files.

 This also is a issue because is hard to install OS related filed on a 
predefined hosting.


3. I found filetype package but it only checks "magic numbers" for a 
limited file types, and docx and other identifies them as zip file(wich are 
archive as technology),

 but I need to identify them as what they really are.


What other non OS dependent solutions that can check if the file is faked 
or with no extension exist ? (pdf,doc,docs,csv,xls,xlsx, ods,odt,odm)

Django - Image crop using a widget as a field in the form

[Paul]

I have a Product Model and Image Model with a Foreign key to the product 
model. 


So in a form for Product creation I will have/need multiple Image File 
Upload inputs. 


I want to replace the default Image file-upload form field with a Image 
(like a plus sign, like add a new image, using a widget). 


When the user click on a add a new image a pop-up will apear with a 
javascript crop. I need to get the data(coordinates) from the javascript 
crop back to Django, use Pillow to crop and fill the Image Model field.


What is the best approach for this mechanism for the form field(will not be 
a real upload) ? , maybe a link to a tutorial 


(I know there are some Django package that do something like that but are 
really what I want regarding crop control)

Restricting the user from closing the browser tab so that the server side APIs are called.

[Rahul Paul]

Hi,

We are working on a django project in which we are developing a two way 
audio visual solution for the users. Now we have certain set of APIs that 
need to be called from JavaScript through ajax request when user ends the 
call through our end-call button. Some of these ajax calls are sequential 
i.e. based on result of one ajax call another ajax call is made.

Now our problem is if the user close the tab or browser using the cross 
button of tab or browser, then these APIs are not called and many of our 
functionalities does not work. Hence to solve this we were looking into the 
following options : 

1. Restricting the user from closing the tab or browser until the user 
clicks on end-call button and all functionalities related to ending the 
call is done.
2. Calling the APIs before the browser or tab close when user tries to 
close the browser or tab.
3. Opening our template as a modal so that we can modify the closing of 
modal to satisfy our use case.

First option is not possible since it poses security risks w.r.t. browser. 
Currently our web page is opening as new tab. We have tried opening the 
page as new window and hiding the menu bar, minimize/maximize and cross 
button, but we could not hide the cross button. 

We tried the second option using window.onbeforeunload and window.onunload 
feature of JavaScript window object, but we could not call the APIs.

We are now thinking of the third option, but here we are stuck as we are 
not sure if the template can be directly rendered as a modal from django 
views. 

Also our web page will have the following major components : 

* video tag, where 2-way A/V will play.
* iframe where we have another feature.
* chat section where communication happens through django channels.
* File upload and download feature.
* Many functionalities are based on API call hence many ajax request.

In short our web page will be heavy and will have a lot of javascript files 
to be loaded. So will we get the same efficiency with modal as we get with 
proper web page? What will be the limitation and if possible how we can 
render our template as modal?

Our main intention have the same flow when the user clicks the end-call 
button or close the tab or browser i.e. all the functionalities that are 
happening when end-call button is clicked, must also happen when the user 
close the tab or browser.

Please help me with resolving this issue. You can also provide options 
other then what we have considered. All suggestions are welcome.

Thank you.

Dear Antonis,

Thank you very much for your quick response.
Sorry, I am newer in this field. I was trying to install LitDB 
(http://www.ikmb.uni-kiel.de/litdb)
I changed the settings as what your suggestion, but not happened.

with port number 5432, it showing
 Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?

Is there any other settings i need to change?
Thanks and Regards

Some reversible migrations cannot be reversed in practice?

[paul]

I've just hit a tricky migration case, and I'd like to check I'm not 
missing something. The summary is that merge migrations make it possible to 
add migrations which cannot be unapplied, even if they are the latest 
migration to be run.

With the migration graph:

M1
|
+--+
|  |
M2a   M2b
|  |
+--+
|
M3(merge)

Now, as far as a can tell, if I want to revert M2b, I have to run 
`manage.py migrate app M1`. If M2a is not reversible, then it's impossible 
to un-apply M2b, even though the dependency graph would allow it. Or to 
consider another pathological case, imagine a long-running series of 
deployed migrations (M2a, M3a, M4a, ...) instead of an immediate merge 
commit; the M2b migration could be impossible to revert without reverting 
many other migrations in the other branch, which could delete user data if 
run in production.

It seems there's a missing command, `manage.py revertmigration M2b`, which 
would walk the dependency graph backwards to figure out which later 
migrations needed to be unapplied (in this case M2b and M3). Absent this 
command, it seems that merge migrations aren't safe to use, and should be 
avoided.

Am I missing something here? Appreciate any insights or workarounds anyone 
has on this subject.
