If it possible to filter out names of objects returned in Django Admin

Question

For my Django CMS Admin I would like to prevent it returning a specific object to the CMS. What is the best way to do this?

I would like to do something like

class MyModuleAdmin(admin.ModelAdmin):
    list_display = ['name']
    list_filter = ('my_module__name__is_not=moduleidontwant',)

Answer 1

You can simply overload get_queryset admin function and filter out items you do not want:

class MyModuleAdmin(admin.ModelAdmin):
    list_display = ['name']

    def get_queryset(self, request):
        queryset = super(MyModuleAdmin, self).get_queryset(request)
        return queryset.exclude(name='moduleidontwant')

Answer 2

# custom_filters.py
from django.contrib.admin import SimpleListFilter

class testFilter(SimpleListFilter):
    """ This filter is being used in django admin panel in specified model."""
    title = 'Title of you field'
    parameter_name = 'field_name'
    
    def queryset(self, request, queryset):
       if not self.value():
           return queryset
       else:
           return queryset.filter(my_module__name__is_not='moduleidontwant') #add your filter here.

Add this testFilter in your list_filter in admin.py file.

# admin.py
from django.contrib import admin
from .models import *
from .custom_filters import testFilter

class MyModuleAdmin(admin.ModelAdmin):
    list_display = ['name']
    list_filter = (testFilter)
