INSTALLED_APPS = [
    'django.contrib.auth',
     ....
    'tabular_permissions',
]

Tabular_permissions possible configurations and their default:

TABULAR_PERMISSIONS_CONFIG = {
    'template': 'tabular_permissions/admin/tabular_permissions.html',
    'exclude': {
        'override': False,
        'apps': [],
        'models': [],
        'function':'tabular_permissions.helpers.dummy_permissions_exclude'
    },

    'apps_customization_func': 'tabular_permissions.helpers.apps_customization_func',
    'custom_permissions_customization_func': 'tabular_permissions.helpers.custom_permissions_customization_func',
}

template

the template which contains the permissions table, you can always customize this template by extending or overriding. Notice that there is a style block which you can override to easily edit the css.

exclude

Control which apps, models to show in the permissions table.

By default tabular_permissions exclude sessions , contenttypes and admin apps from showing their models in the permissions table. If you want to show them you can switch override to False.

apps & models lists would contain the names of the apps and models you wish to exclude.

function is a dotted path of a custom function which receive the model as a parameter to decide either to exclude it or not, default to a dummy function that always return False (ie do not exclude)

auto_implement

By default, just by including tabular_permissions in your installed_apps, the django.contrib.admin.UserAdmin (and GroupAdmin) are "patched" to include the tabular_permissions widget. If you have a custom UserAdmin, then set this option to False and make sure you either:

1. Inherit from tabular_permissions.admin.TabularPermissionsUserAdmin and tabular_permissions.admin.TabularPermissionsGroupAdmin for User & Group ModelAdmin.
2. Or for a more direct and compact way, inherit your ModelAdmin from tabular_permissions.admin.UserTabularPermissionsMixin and tabular_permissions.admin.GroupTabularPermissionsMixin (comes before admin.ModelAdmin in the mro),
3. Set the user_permissions widget to tabular_permissions.widgets.TabularPermissionsWidget and remember to send a 3rd argument 'permissions' for Group Model Admin. See tabular_permissions.admin for information.

use_for_concrete

Default: False (new in version 2.8)

There was an inconsistency with proxy models permissions (Django ticket 11154) which got fixed in Django 2.1 In case you're on an django <2.1 and you have proxy models and you created their permissions by hand (via this gist maybe), then turn off this option in order to correctly assign your newly created permissions. For django > 2.1, leave it as is you should be good.

custom_permission_translation

A dotted path function to translate the custom permission. This function gets passed the permissions codename, verbose_name and its relevant content_type_id. The function will try to translate the permission verbose_name.

apps_customization_func

A dotted path function to control the whole permissions objects passed to the widget. Sometimes you use custom menu where apps and models are ordered in a more "user friendly" manner and not necessarily in the "actual programmatic" apps & models order. You can use this option to get a hold of the whole ordered dict and shuffle its content around moving models from one app to the other and do all kind of crazy stuff to get just the right table of permissions.

custom_permissions_customization_func

A dotted path function to control the "extra" permissions which will be displayed on the default django widget. Suppose a model is removed, or an app is commented out of INSTALLED_APPS; its permissions are still in the permissions table, and it will be picked up. Use this function to manipulate and order those permissions and return them . The permissions are passed a list of tuples , like this [(perm_id, perm_name), (perm_id, perm_name), ...]

JavaScript:

Located at 'static/tabular_permissions/tabular_permissions.js', it have 2 responsibilities:

1. Upon form submit, the checked permissions in the table are dynamically appended to the form default permission input so the backend can carry on its functionality normally and correctly.
2. Add handlers for column and row select-all checkboxes.

Compatibility:

Version >= 2.0 only supports Django >= 1.11 For earlier versions of django use django-tabular-permissions 1.0.9.
