Certain models not showing up in django 4 admin despite being registered-CodePudding

Using django 4.0.3 and the restframework.

I have serval models registered in django admin:

@admin.register(models.Drug)
class DrugAdmin(admin.ModelAdmin):
    list_display = ('apl_label', 'name', 'drug_class', 'atc_code', )
    
@admin.register(models.Organism)
class OrganismAdmin(admin.ModelAdmin):
    list_display = ('apl_label', 'long_name', 'short_name', 'genus', 'flagged', 'notes')

....

For some reason, some o fthe models are not showing up in the admin view. In this example, Organism shows up, but Drug is hidden. I can go to http://localhost:8000/admin/api/drug/ and access this admin page, but it is not listed under http://localhost:8000/admin/. There is no error message either. I did run makemigrations and migrate.

Permissions are only set globally in settings.py:

...
'DEFAULT_AUTHENTICATION_CLASSES': [
    'rest_framework.authentication.SessionAuthentication',
],

It is always the same models not showing up. I tried deleting the database and creating everything from scratch. No luck. Why does Django decide to not show certain models?

If this solves your problem you can use this. Or you can check this to understand is the problem because of your admin.py or not.

This will work properly:

from django.contrib import admin
from .models import (
    Drug,
    Organism,
    )

admin.site.register(Drug)
admin.site.register(Organism)

CodePudding user response：

That should not happen. Your code seems perfectly fine to me. Make sure your top imports contain the following lines too:-

from django.contrib import admin
from . import models

If your models don't have any extra customization like custom fieldsets and/or custom section-titles, you can try using the regular old admin.site.register(models.modelname). Maybe the decorator is malfunctioning for you for some reason, though I have never seen that happen before.
