How to add new fields to users according to its group (role) in Django
I'm trying to do a logistics web application in Django and I need to assign different roles to the users. I have normal users (clients), employees (office employees, delivery man, truck drivers...) and supervisors. I need to do the following: Office employees and delivery man users: need to have an office assigned Truck drivers users: need to have an assigned route I've made 2 models (Offices and Routes) but I don't know how to relate the users with these models. I've read websites that create custom classes inherited from AbstractBaseUser or AbstractUser, but I don't know how to do it with this special case. I hope to hear the right answer here.

Download (powerpoint) - file with django REST framework
I am running a django app and I want to be able to download a powerpoint file with an API call using django REST framework and the library requests. My model is very simple: class FileCollection(models.Model): name = models.CharField(max_length=120, null=True, blank=True) store_file = models.FileField(upload_to='file_storage_api/', null=True, blank=True) creation_date = models.DateTimeField(null=True, blank=True) Then in my view I want to query different instances of the FileCollection model which I then want to download. First I tried just calling the link but my upload files should be private that's why I would like to use token authentication that I already have implemented. I also tried following this answer but https://stackoverflow.com/questions/38697529/ but can't get it to work. I also read the REST doc on Renderers but I don't really get how to implement them. Is there any (easy) way of a downloading a powerpoint file with REST and requests? Any help is very much appreciated, thanks very much in advance! -
when I click on next on pagination all previous query parameter are lost in django

Unable to access / var / tmp in Subprocess via Django
I created a script that outputs the execution result of a shell script to a Web screen using Django and subprocess of python. Specifically, the following two scripts were created. test.py #!/usr/bin/python import sys,os import subprocess import syslog command_list = ['/bin/sh', '/var/tmp/test.sh'] proc = subprocess.Popen(args=command_list, stdout=subprocess.PIPE, stderr=subprocess.PIPE, cwd=os.path.dirname(command_list[0]), shell=False) result = proc.communicate(input=None) print str( result ) test.sh #!/bin/bash echo "begin" cat /var/tmp/data.txt data.txt data1 data2 Unit tests were performed on the two scripts, and they were confirmed to work properly.

Why do I get 'detail: not found' for primary key formatted as '12-345.78'?
When I try to display detail info calling e.g. /api/products/12-345.67/, I get detail: Not found. as a response. As you can see, product IDs are formatted as 12-345.67. My first suspect was the RegEx validator (listed below), but it works the same way with or without it. Model, serializers, viewsets and URLs are defined this way: # models.py: class Product(models.Model): product_id = models.CharField(max_length=9, primary_key=True) name = models.CharField(max_length=40) is_active = models.BooleanField(default=True) def __str__(self): return self.product_id # serializers.py: class ProductSerializer(serializers.ModelSerializer): product_id = serializers.RegexField(regex='^\d{2}-\d{3}\.\d{2}$', max_length=9, min_length=9, allow_blank=False) name = serializers.CharField(min_length=6, max_length=50, allow_blank=False) class Meta: model = Product fields = '__all__' class ProductViewSet(viewsets.ModelViewSet): queryset = Product.objects.all() serializer_class = ProductSerializer lookup_field = 'product_id' # urls.py: router = routers.DefaultRouter() router.register(r'products', ProductViewSet, basename='products') (...) urlpatterns = [ path('api/', include(router.urls)), (...) -

Return the progress to the template each value change in Django
I want to show the progress of the task going in the back-end in order let the user know that the work is still in progress. I have ajax call to a function to get the final value. In back end it will take lot of time to complete the job, but each time i have the progress of the job in one variable i want to show the values of this variable in the front end. For example my ajax function is def ajax_call(request): j = 0 for i in range(1,10000): j += i res = {'data': j} return JsonResponse(res, safe=False) As we know it will return the final value of j. But i want to show the value of j in the front end in each change. Is there any simple way to do this using celery or something -

How can I use '{{' , '}}' letter for plain text on template?
The problem was shown when I wanted to explain syntaxes of Django templates on my html document. However, {{ or {% letters are recognized and by the template engine, so I couldn't use them for just plain string. How can I make Django template engine to bypass that letters? I have already tried to use some letters, like backslash \ or Django template's comment function {# #}. First, backslash was not worth at all. Second, comment function makes bypassing everything inside the function. It is an example of my situation: <p>A variable outputs a value from the context, which is a dict-like object mapping keys to values. Variables are surrounded by {{ and }} like this:</p> <p>My first name is {{ first_name }}. My last name is {{ last_name }}.</p> I expected the output have to be like: A variable outputs a value from the context, which is a dict-like object mapping keys to values. Variables are surrounded by {{ and }} like this: My first name is {{ first_name }}. My last name is {{ last_name }}. But actually, it was like: A variable outputs a value from the context, which is a dict-like object mapping keys to values. … -

Celery tasks don't send email to admins on logger critical messages
My celery tasks don't send an email to application admins each time I call logger.critical. I'm building a Django application The current configuration of my project, allows the admins of the application to receive an email each time a logger.critical message is created. This was pretty straight forward to set up. For some reason, which I'm not figuring out, the code that runs inside a celery task, does not have the same behavior. Does celery actually event allow this to be done? Am I missing some configuration? Does anyone got this problem and was able to solve it? Using: Django 1.11 Celery 4.3 Thanks for any help. -
