# core.patch_django

## Overview

Monkey-patches Django permission codenames to use CRUD naming conventions.

## `get_builtin_permissions` {#get_builtin_permissions}

Return ``(codename, name)`` pairs for the permissions Django creates for a model, with actions renamed.

Each action in ``opts.default_permissions`` is renamed through ``PERMISSION_NAMES_MAPPING``, and a
pair that two actions map to appears once. Importing this module installs it in place of Django's
``_get_builtin_permissions``, which it copies:
https://github.com/django/django/blob/f302343380c77e1eb5dab3b64dd70895a95926ca/django/contrib/auth/management/__init__.py#L22-L35

### Signature {#get_builtin_permissions-signature}

`get_builtin_permissions(opts)`

#### Parameters {#get_builtin_permissions-parameters}

| Name | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| <span id="get_builtin_permissions-param-opts">opts</span> |  | yes |  |  |

### Source {#get_builtin_permissions-source}

`server/vueda/core/patch_django.py:64`

## `get_permission_codename` {#get_permission_codename}

Return the permission codename for ``action`` on the model ``opts`` describes, after renaming the action.

``PERMISSION_NAMES_MAPPING`` renames Django's actions; by default ``add`` becomes ``create``,
``change`` becomes ``update``, and ``view`` becomes ``read``. Importing this module installs it as
``django.contrib.auth.get_permission_codename``.

### Signature {#get_permission_codename-signature}

`get_permission_codename(action, opts)`

#### Parameters {#get_permission_codename-parameters}

| Name | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| <span id="get_permission_codename-param-action">action</span> |  | yes |  |  |
| <span id="get_permission_codename-param-opts">opts</span> |  | yes |  |  |
