Hey,
I want to do math operations in django default template engine and I want to add a number to another number like this:
{% for num in custom_range %}
<p>{{ num + 1 }}</p>
{% endfor %}
But, raising error Could not parse the remainder: ' + 1' from 'num + 1'
I searched this issue on google and by stackoverflow users answers used sub filter but seems that this filter is not in current stable version
Have you tried {{num}} +1

Don't do that, use a model and foreing key

Don't do that, use a model and foreing key
I want to store an instance directly because the instance might not exist in its orignal table

I want to store an instance directly because the instance might not exist in its orignal table
This is the actual problem lets say there is a row update on a table , i need both old and new instance to be stored some where so that a cron job compares both and generates a change log

So i am looking for a field that stores the object

hi! i got this kind of error and i have no idea how to solve this. After googling i think it is related with url path names, but i dont see any mistakes...
Error:
File "C:\Users\Aziz\AppData\Local\Programs\Python\Python310\lib\sre_parse.py", line 831, in _parse
raise source.error(err.msg, len(name) + 1) from None
re.error: redefinition of group name 'pk' as group 2; was group 1 at position 20
Repo:

Aziz
all url names are unique
ms tk
make authenticationi as a seperate service
how can i relate (FK) user in model for other project
Charly
how can i relate (FK) user in model for other project
you don't, that's not how authentication should work
ms tk
you don't, that's not how authentication should work
so the way of storing user should be with the decoded jwt, right?

Hey guys. I need a suggestion. I need to create an app for making appointments only for available time, I’ve created 3 models(may be shortened to 2): 1 for available days with the counter field(how many available time records are linked to this day), 1 for available time with foreign key to days and boolean “is_available”, and 1 for appointment itself with foreign key to time model. I have 3 Model forms to proceed the information step by step and make queryselection based on data I receive. But I can’t access this data properly, coz when django redirects user from one form to another, http method is GET
What is the best practice for appointment creation? Haven’t found any attractive solution in the internet
Pm me If you need my code

If the structure of the database corresponds to the code, migrations may not be used

You can generate the models of an existing db
python manage.py inspectdb > models.py

A'd adding a class meta

In a Django project am working on, I need to have 2 user types. One is an Owner and the other is a Reseller
The superuser creates owners, and the owners create resellers under them. I want to keep track of which Resellers are registered under which Owner by connecting Owners and Resellers table via a Foreign Key. So no reseller can create an account by themselves, their owners should do that for them. How can I accomplish this?
you can find what I have tried so far in the link below

Well you can create a user manager, and assign permissions to those users. Then create a model for each user and then use a foreign key or a signal to link each reseller to an owner. This is how I would have done it, although I know it is not the best practice and there are far better options. Good luck 😊

Create a user manager (superuser, owner, reseller) and a user model, assign permissions to each user. That's all I can think of.

The thing is,
Superuser creates Owners and the Owners create as many resellers as they want under them,, how can i track which resellers are under which owners,, how will the foreign key relationship be,,?

So the owner creates the reseller. Alright model;
Reseller (...):
owner = models.ForeignKey(User, on_delete=models.CASCADE)

Just like user=request.user on the views panel

Then for the owner;
Owner = models.manytomany(Reseller)

Then for the owner;
Owner (...):
Owner = models.manytomany(Reseller)

do u mean sth like this👇🏾

class User(AbstractBaseUser, PermissionsMixin):
# ...list of other fields
is_owner = models.BooleanField(default=False)
is_reseller = models.BooleanField(default=False)

objects = UserManager()
class Owner(models.Model):
user = models.OneToOneField(
User, on_delete=models.CASCADE)

user = models.OneToOneField(

owner = models.ForeignKey(

Yes, but do not forget to add an owner class and reseller class to the User manager, so they can be recognized as user roles

i need clarification why in (example): path('<int:question_id>/', views.detail, name='detail'), exactly this order, why the first <int:question_id>/ second views.detail third name='detail, and not vice versa. only with other parts of the code and, in principle, an explanation of what is responsible for what
