Re: Any django reusable app for outdoor & indoor location, GPS tracking?

['Federico Capoano' via Django users]

Hey everyone,

I forgot to follow up on this thread.

django-loci  now provides 
abstract/base classes for models, admin, channels so other developers can 
use this reusable app as a kind of library.

There's ample room for improving this new reusable app but nonetheless I 
hope it will be a useful addition to the django ecosystem.

Best regards
Federico

Re: Admin site and Model

[Fidel Leon]

You need to add your model to the app's admin.py file.

As an example:

Re: Crazy Idea: OOP for "Hyperlink"

[guettli]

In my use case there is no model involved.

I have a django url-mapping (regex to view) not model.

Django-channels request depending Middleware

[Marius Räsener]

Hey everybody,

We are using a Middleware to inject postgresql schemas into queries based on a 
subdomain. You can have a look how it‘s done here:
https://github.com/systori/systori/blob/dev/systori/apps/company/middleware.py

Now, for channels I‘ve noticed that there is no usual request, right?
So, if I‘m connecting a WS it doesn‘t hit the Middleware. 
Are there any guides or docs available or any recommendations how to solve this 
properly for channels?

Thx,
Marius

Re: importError

[Fidel Leon]

>From the look of things, it seems:
-You're following the Django v2.0 tutorial.
-You have installed a Django v1 version.

This is an example with Django v2:

>>> import django
>>> django.get_version()
*'2.0.5' *
>>> from django.urls import include, path
>>>
*[No error]*

And this is an example with Django v1.11

>>> from django import get_version
>>> get_version()
*'1.11.13' *
>>> from django.urls import include, urls
Traceback (most recent call last):
 File "", line 1, in 
*ImportError: cannot import name 'include'*
>>>

So either you upgrade your Django package, or you follow your Django
version's tutorial :)

Fixtures: core.serializers.sort_dependencies sorts models in the wrong order for FK constraints

[Andrew Wrigley]

 

Hi all,


I'm trying to dump a database fixture, and load it again to run tests. When 
I run `python manage.py test`, I get:

 

> IntegrityError: Problem installing fixtures: insert or update on table 
> "publisher_journaldupextid" violates foreign key constraint 
> "publisher_journaldup_journal_id_67a6a414_fk_publisher"
> DETAIL:  Key (journal_id)=(153) is not present in table 
> "publisher_journal".

 

On further inspection this is because 
django.core.serializers.sort_dependencies, which I'm using to create the 
fixture, is sorting models in the wrong order. Looking at the source of 
sort_dependencies, the only constraints on the ordering of models relate to 
natural keys. I'm not using natural keys, but my database has foreign key 
constraints so order of loading is still important.

 

Am I missing something about how to save and load models without violating 
FK constraints?

sphinx is showing the django base views instead of my own views.py

[Anthony Petrillo]

The view being shown when using Sphinx on a Django site is: 




The beginning of my views.py is:


import os

from django.shortcuts import render, redirect 

from django.urls import reverse 

from django.http import HttpResponse, HttpResponseRedirect 

from django.utils import timezone

from . forms import PlayForm, RollForm, checkBoard, BossForm

from random import randint 

from . templatetags.playExtras import translateDice 

from .models import Board, Winner, Boss


def getFirstFolder(req):

""" return the string between first two / - this is a hack, find out 
how to do it with the object """

r = req.split("'")

loc = r[1].find('/',1)

x = r[1][1:loc]

return(x)


def loadBoard(request,context,location=''):

''' Load the board from the database into context. Add a hyperlink for 
available squares.


:param context: context for template

:type context: dictionary


:param location: Comma seperated string of available locations or empty 
string so no links included.

:type location: str


:return: 'not on the board' or 'all taken' or comma seperated string of 
location options such as 'A0,B0'

:rtype: str

'''

req = request.__str__()

I was getting errors if I didn't show Sphinx where the Python was located. 
The path additions I made in the Sphinx's conf.py are:

ourPaths = [
'/game/',
'/game/game',
'/game/play',
'/game/play/templatetags'
]
for p in ourPaths:
abspath = os.path.abspath('.')  + p
print('path..',abspath)
sys.path.insert(0, abspath)
# Need to point to where the Django is on this system. FIND OUT HOW TO MAKE 
THIS RELATIVE
sys.path.insert(0,'/home/ajp/Downloads/env/lib/python3.5/site-packages')
sys.path.insert(0,'/home/ajp/Downloads/env/lib/python3.5/site-packages/django')


The views.rst file I'm using: 

views module
==

.. automodule:: views
:members:
:undoc-members:
:show-inheritance:

I searched for days but I'm afraid I do not know the right terms search for 
to find the answer. I posted on stackoverflow for a couple weeks and no 
responses at all. 

I'm okay with the other code showing up, but I'd need to see my code in the 
manual as well.

Thank you for any help you can give.

Query Regarding Django Signals

[Nipun Arora]

Hello Community 

I was puzzled by the fact that if django signals are not asynchronous why 
do we use them as in when ever i want some trigger on post_save can't  i 
simply write that particular trigger in the same function that handles the 
request for saving a new object in django views..?
as in :


def handlerequest(Request):
save instance to db 
   Do the work i would do in the method handling the signal post_save

RE: Query Regarding Django Signals

[Matthew Pava]

The advantage with the signals is that you can put all that code in one place.  
You may have different views that are saving the same model, and it isn’t DRY 
to have to put that same code in multiple locations.

Re: Django-channels request depending Middleware

[Andrew Godwin]

That's correct - Django middleware only runs on HTTP request objects, and
so doesn't work in a WebSocket context. The recommended alternative is to
write ASGI middleware for this purpose.

Unfortunately, there is not good documentation on this yet, but you can see
a bit about it here, in the authentication docs:
http://channels.readthedocs.io/en/latest/topics/authentication.html#custom-authentication

Re: I got error when working on "Writing your first Django app, part 5" of tutorial

[brzrkr]

It seems you need to point your Django project to your urls.py file. See: 
https://docs.djangoproject.com/en/2.0/ref/settings/#root-urlconf
This should point to your urls.py file, the file containing the 
`urlpatterns` variable, which is a list of `path()` statements.
For example if your urls.py file is in `/myapp/urls.py`, in your 
settings.py you should write: `ROOT_URLCONF = myapp.urls`.

Custom User model writes email in username column and vice-versa (postgresql)

[brzrkr]

Hi guys, I'm new here.

I customised the User model of my project by inheriting from 
AbstractBaseUser, I've also made a custom Manager through BaseUserManager 
and added an auth backend to login through email instead of username.
The reason I did this is to let users register and login using their email 
but still have a username, that doesn't have to be unique (they're 
differentiated through a discriminator not unlike the one Discord uses, if 
you know it, like brzrkr#0001 and brzrkr#2342 may exist at the same time 
and both be known as brzrkr).

The problem is, when I create a user with `manage.py createsuperuser`, the 
database saves the email in the "username" field and the username in the 
"email" field, even though I set all overridden variables to the correct 
fields (see below for code).

NOTE: I have also posted a question about this on stackoverflow but it's 
been ignored for some days now, so I've looked for a place where people may 
be more familiar with Django in particular. Here is the link to 
it: https://stackoverflow.com/q/50104202/8599834

Now here's the *code of the User model* not including irrelevant methods:
class User(AbstractBaseUser, PermissionsMixin):
"""Override of the Django class to handle user authentication."""
# ==Identification==
# To allow for multiple users with the same username, users are 
publicly identified with username#identifier.
# Internally, only the couple username + identifier must be unique, but 
either can be duplicate on their own.
username = models.CharField(max_length=150, db_column="user_username")
# The identifier is stored as a string of digits including trailing 
zeroes.
# It is assigned at creation and modification of a user's nick using 
the first value that doesn't conflict.
identifier = models.CharField(max_length=settings.IDENTIFIER_DIGITS)

email = models.EmailField(unique=True, db_column="user_email")

objects = UserManagerOverride()  # Override the default manager to 
customise user creation.

is_superuser = models.BooleanField(default=False)
is_staff = models.BooleanField(default=False)
is_active = models.BooleanField(default=True)

USERNAME_FIELD = "email"
EMAIL_FIELD = "email"
REQUIRED_FIELDS = ["username"]

class Meta:
unique_together = ("username", "identifier")

This is the *Manager*. This is mostly identical to what BaseUserManager 
does except for some quirks. I haven't included the generate_identifier 
method because it's not relevant:
class UserManagerOverride(BaseUserManager):
"""Override of the default Django user manager."""
def _create_user(self, email, username, password, **extra_fields):
"""Override the parent function to create a user and save it in the 
database."""
if not email:
raise ValueError('An email is required.')

# Prepare the data to be stored into the database.
email = self.normalize_email(email)
username = self.model.normalize_username(username)
identifier = self.generate_identifier(username)

# Make the user instance.
user = self.model(username=username, email=email, 
identifier=identifier, **extra_fields)

# Add the password after encrypting.
user.set_password(password)

try:
# Save to database.
user.save(using=self._db)
except Exception:
# If there was an error, scratch the user row to preserve 
integrity with User and UserData primary keys.
user.delete()
raise
else:
# Create a UserData record for this user.
# Thanks to the try-else, we only do this if the code raised no 
exceptions.
UserData.objects.create(user=user)

return user

def create_user(self, email, username, password=None, **extra_fields):
"""Override parent function to create a regular user account."""
extra_fields.setdefault('is_staff', False)
extra_fields.setdefault('is_superuser', False)
return self._create_user(email, username, password, **extra_fields)

def create_superuser(self, email, username, password, **extra_fields):
"""Override parent function to create a superuser account."""
extra_fields.setdefault('is_staff', True)
extra_fields.setdefault('is_superuser', True)

if extra_fields.get('is_staff') is not True:
raise ValueError('Superuser must have is_staff=True.')
if extra_fields.get('is_superuser') is not True:
raise ValueError('Superuser must have is_superuser=True.')

return self._create_user(username, email, password, **extra_fields)

And finally the *auth backend*, although this should only come into play 
when trying to log in, so it isn't involved in the problem (at least for 
now):
class EmailBackend(ModelBackend):
"""Allow authentication using email instead of username."""
def authenticate(self, username=

Re: Django-admin problem

Hi,

By the looks of error you're running windows.

By default scripts are not in PATH so you need to type something like
c:\python36\scripts\django-admin.py

Or you should use virtualenv (or pipenv) which would set path correctly.

Trigger password reset

[Álmos Kovács]

Hi Everyone,

I got stucked with triggering password reset in my custom view. I want to
trigger it in different places but I want to use the OOTB souliton. I've
found that I can import and use
from django.contrib.auth.forms import PasswordResetForm
and
from django.contrib.auth.views import password_reset
but it didn't send any email. I wasn't able to see any emails using the
console email debugger option in the settings.

I've tried these ways:
def reset_password(request):
reset_form = PasswordResetForm({'email': request.POST.get('email')})
assert reset_form.is_valid()
reset_form.save(
request=request,
use_https=request.is_secure(),
subject_template_name='registration/account_creation_subject.txt',
email_template_name='registration/account_creation_email.html',
)
return HttpResponse("the given mail: " + request.POST.get('email'))

def reset_password (request):
return password_reset(request,
post_reset_redirect="/admin/accounts/list/")

Could anyone help me to triggering password reset from my views?

Thanks in advance,
Álmos

Re: Query Regarding Django Signals

[Jani Tiainen]

Hi,

Signals are also good for decoupling things.

For example you want to do some post save action for third party models.

Hello Community

I was puzzled by the fact that if django signals are not asynchronous why
do we use them as in when ever i want some trigger on post_save can't  i
simply write that particular trigger in the same function that handles the

as in :


def handlerequest(Request):
save instance to db
   Do the work i would do in the method handling the signal post_save

You can also just write a Celery task to do your async stuff and trigger it
