 Hi everyone, I am new to programming, more than 4 months, I had an 
 issue when making  migrations for my apps. 

 I run :" python manage.py makemigrations " and  I got a error.
  It said:  TypeError: __init__() got an unexpected keyword argument 'on 
 delete'
 I'm Using Django 3.2.9 
 Can someone explain it for me? And how to fix it.

 Thanks and Regards,

Student Management System kin Django

[Eugene TUYIZERE]

Dear Team,

I am developing a student management system and I am stuck at the point
below which I need your idea.

I need to record school fees every semester and promote a student from one
level (year) to the next level every year. Like 1st Year to second year.

How can I achieve this to avoid data duplication in the database.

Regards,

-- 
*Eugene*

Dear Gilwell,

That is where I want an idea. I do not understand how I do the diagram.

Play audio File

[Shada Bahassan]

  Hello everyone,

I'm a beginner on Django.

I have audio files and I want to read the path when I click the play 
button. I discovered some resources that upload audio files as object 
models. but I don't want to handle as the model, I just want to read it 
when I call the play sound method.

Any pointers in the right direction would be greatly appreciated.

Sorting in Django admin site on different locale

[Roland Leners]

I am currently learning Python and Django via building a simple Web 
application. It involves objects with character fields that take values in 
different languages (French and Spanish) and I face an issue with sorting 
on those values in the Django administration site. 

Here are sample sets:
French: dataFr = ['être', 'gronder', 'gérer', 'éviter', 'exiger']
Spanish: dataEs = ['dos', 'acompasar', 'acompañar', 'día']

The following works fine in Python:

import locale
locale.setlocale(locale.LC_ALL,"fr_FR.utf8") 
sorted(dataFr, key=locale.strxfrm) 
> ['être', 'éviter', 'exiger', 'gérer', 'gronder'] #which is the desired 
result.
sorted(dataEs, key=locale.strxfrm)
> ['acompañar', 'acompasar', 'día', 'dos'] #which is also the desired 
result.

(French as well as Spanish local settings seem to work indifferently for 
sorting  French and Spanish)

In Django, the simplified model is as follows:

from django import models

class Word(models.Model):
content = models.CharField(max_length=32, unique=True)
class Meta:
abstract = True

class FrenchWord(Word)

The relevant part of the admin.py file is:

from django.contrib import admin
from .models import FrenchWord

@admin.register(FrenchWord)
class FrenchWord(admin.ModelAdmin):
list_display = ('content',)
ordering = ('content',)

Now my question is how to enforce ordering according to the fr_FR.utf8 
locale? I have tried all kinds of stuff, taking inspiration from various 
sites, but I do not succeed.

Thanks in advance.

Re: Urgent need help regarding to localhost

[Bernard Mallala]

What troubleshooting have you attempted so far?
What is the composition of your development environment?
Have you checked if the port is open to eliminate firewall and or network 
related issues?
Have you checked to make sure that your postgres database server is running?
Are you able to connect and authenticate to your postgres database in 
command line and terminal ?
e.t.c.

Re: Student Management System kin Django

[Bernard Mallala]

Eugene,

Your question is very broad. The combination of the business logic for the 
student management system plus database normalization best practices will 
result in the right database schema for this platform.
Example business logic :
- User must have a B or higher to be eligible to move to the next grade or 
auto upgraded to the next grade
- User can be upgraded to the next grade but will not be eligible to enroll 
if the account balance for the prior year is not zero

Some of the business rules will guide your database design/model creation.

You need to be able to do the above resulting in an ERD which you can then 
share and someone can then offer additional feedback.
