# User Model
|
|
|
|
## Autenticación Django
|
|
|
|
- Sistema de autenticación *built-in*
|
|
- Framework para características básicas
|
|
- Registro
|
|
- Login
|
|
- Autorización
|
|
- Se integran con el panel de administración de Django
|
|
|
|
### Django user model
|
|
|
|
- Es la fundación del sistema de autenticación de Django
|
|
- Django incorpora por defecto un modelo de usuario
|
|
- Utiliza un nombre de usuario en vez de un email
|
|
- No es facil de personalizar
|
|
- Creación de modelo de usuario personalizado para nuevos proyectos
|
|
- Permite el uso de email en vz de nombre de usuario
|
|
- Asegura compatibilidad del proyecto con posibles cambios del modelo usuario
|
|
en versiones futuras
|
|
|
|
### Creación del modelo
|
|
|
|
- Basado en la clase `AbstractBaseUser` y `PermissionsMixin`
|
|
- Creación de administrador personalizado
|
|
- Se establece `AUTH_USER_MODEL` en `settings.py` para utlizar este modelo
|
|
- Creación y ejecución de las migraciones
|
|
|
|
### AbstractBaseUser
|
|
|
|
- Proporciona las características de autenticación
|
|
- No incluye campos
|
|
|
|
### PermissionsMixin
|
|
|
|
- Soporte para el sistema de permisos de Django
|
|
- Incuye todos los campos y métodos necesarios
|
|
|
|
### Problemas comunes
|
|
|
|
- Correr migraciones antes de crear el modelo personalizado
|
|
- Crear el modelo personalizado primero
|
|
- Tipeo
|
|
- Indentación
|
|
|
|
## User Model personalizado
|
|
|
|
### Campos de usuario
|
|
|
|
- email `EmailField`
|
|
- name `CharField`
|
|
- is_active `BooleanField`
|
|
- is_staff `BooleanField`
|
|
|
|
### User Model administrador
|
|
|
|
- Usado para administar objetos
|
|
- Lógica personalizada para crear objetos
|
|
- **Hash** passwords
|
|
- Metodos para el CLI de Django
|
|
- Create superuser
|
|
|
|
### BaseUserManager
|
|
|
|
- Clase base para administrar usuarios
|
|
- Métodos útliles de ayuda
|
|
- `normalize_email` para almacenar emails de forma consistente
|
|
- Métodos a definir
|
|
- `create_user` llamado al crear usuarios
|
|
- `create_superuser` usado por el CLI para crear un super usuario (**admin**)
|
|
|
|
### Agregando Unitetst para el modelo usuario personalizado
|
|
|
|
[test_models.py](./app/core/tests/tests_models.py)
|
|
|
|
```py
|
|
from django.test import TestCase
|
|
from django.contrib.auth import get_user_model
|
|
|
|
class ModelTests(TestCase):
|
|
|
|
def test_create_user_with_email_sucessfull(self):
|
|
email = 'test@example.com'
|
|
password = 'testpass123'
|
|
user = get_user_model().objects.create_user(
|
|
email=email,
|
|
password=password,
|
|
)
|
|
self.assertEqual(user.email, email)
|
|
self.assertTrue(user.check_password(password))
|
|
```
|
|
|
|
## Agregar usuario personalizado al proyecto
|
|
|
|
[models.py](./app/core/models.py)
|
|
|
|
```py
|
|
from django.db import models
|
|
from django.contrib.auth.models import (
|
|
AbstractBaseUser,
|
|
BaseUserManager,
|
|
PermissionsMixin,
|
|
)
|
|
|
|
|
|
class UserManager(BaseUserManager):
|
|
"""Manager for users."""
|
|
|
|
def create_user(self, email, password=None, **extra_fields):
|
|
"""Create, save and return a new user."""
|
|
user = self.model(email=email, **extra_fields)
|
|
user.set_password(password)
|
|
user.save(using=self._db)
|
|
|
|
return user
|
|
|
|
|
|
class User(AbstractBaseUser, PermissionsMixin):
|
|
"""User in the system."""
|
|
email = models.EmailField(max_length=255, unique=True)
|
|
name = models.CharField(max_length=255)
|
|
is_active = models.BooleanField(default=True)
|
|
is_staff = models.BooleanField(default=False)
|
|
# Asignar el UserManager a esta clase User
|
|
objects = UserManager()
|
|
|
|
USERNAME_FIELD = 'email'
|
|
```
|
|
|
|
Actualizar `settings.py` para que Django utilize este modelo de autenticación
|
|
agregando al final del archivo lo sgte.
|
|
|
|
```py
|
|
...
|
|

## Django Admin
|
|
|
|
Es la interfáz gráfica para los modelos creados en el proyecto, permite
|
|
la administración basica C.R.U.D.
|
|
Requiere muy poco cóidgo para ser usado
|
|
|
|
|
|
|
|
Se activa por modelo, en [`admin.py`](./app/core/admin.py)
|
|
|
|
### Personalización del administrador
|
|
|
|
Se crea una clase basada en `ModelAdmin` o `UserAdmin` donde se sobrescribe o
|
|
establecen variables de clase
|
|
|
|
ejemplo
|
|
|
|
```py
|
|
class UserAdmin(BaseUserAdmin):
|
|
"""Define de admin pages for users."""
|
|
ordering = ['id']
|
|
list_display = ['emial', 'name']
|
|
fieldsets = (
|
|
(None, {'fields': ('email', 'password')}),
|
|
)
|
|
readonly_files = ['last_login']
|
|
add_fieldsets = (
|
|
(None, {
|
|
'classes': ('wide',),
|
|
'fields': (
|
|
'email',
|
|
),
|
|
})
|
|
)
|
|
```
|
|
|
|
- `ordening` 
|
|
- `list_display` 
|
|
- `fieldsets` 
|
|
- `readonly_fields` 
|
|
- `add_fieldsets` 
|
|
|
|
### Creando test para el administrador
|
|
|
|
[`app/core/tests/test_models.py`](./app/core/tests/test_admin.py)
|
|
|
|
```py
|
|
class AdminSiteTests(TestCase):
|
|
"""Tests for Django admin."""
|
|
|
|
def setUp(self):
|
|
"""Create user and client."""
|
|
self.client = Client()
|
|
self.admin_user = get_user_model().objects.create_superuser(
|
|
email='admin@example.com',
|
|
password='testpass123',
|
|
)
|
|
self.client.force_login(self.admin_user)
|
|
self.user = get_user_model().objects.create_user(
|
|
email='user@example.com',
|
|
password='testpass123',
|
|
name='Test User'
|
|
)
|
|
|
|
def test_users_list(self):
|
|
"""Test that users are listed on page."""
|
|
url = reverse('admin:core_user_changelist')
|
|
res = self.client.get(url)
|
|
|
|
self.assertContains(res, self.user.name)
|
|
self.assertContains(res, self.user.email)
|
|
```

### Activar admin para core app
|
|
|
|
En [`admin.py`](./app/core/admin.py)
|
|
|
|
```py
|
|
from django.contrib import admin
|
|
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
|
|
from core import models
|
|
|
|
class UserAdmin(BaseUserAdmin):
|
|
"""Define the admin pages for users."""
|
|
ordering = ['id']
|
|
list_display = ['email', 'name']
|
|
|
|
admin.site.register(models.User, UserAdmin)
|
|
```
|
|
|
|
- **Admin**
|
|
|
|
- **CORE** Section
|
|
|
|
- **CORE** Usuarios, requiere modificar pues espera campos que el modelo no tiene
|
|
|
|
|
|
### Modificar admin para que use los campos de usuario personalizado
|
|
|
|
```py
|
|
from django.contrib import admin
|
|
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
|
|
from django.utils.translation import gettext_lazy as _
|
|
from core import models
|
|
|
|
class UserAdmin(BaseUserAdmin):
|
|
"""Define the admin pages for users."""
|
|
ordering = ['id']
|
|
list_display = ['email', 'name']
|
|
filedsets = (
|
|
(None, {'fields': ('email', 'password')}),
|
|
(
|
|
_('Permissions'),
|
|
{
|
|
'fields': (
|
|
'is_active',
|
|
'is_staff',
|
|
'is_superuser',
|
|
)
|
|
}
|
|
),
|
|
(_('Important dates', {'fields': ('last_login',)})),
|
|
)
|
|
readonly_fields = ['last_login']
|
|
|
|
admin.site.register(models.User, UserAdmin)
|
|
```
|
|
|
|
- Administrador de usuario personalizado
|
|
|
|
|
|
- Cambio de lenguaje y timezone, y traducción `gettext_lazy`
|
|
|
|
|
|
- Requiere modificar pues espera campos que el modelo no tiene
|
|
- 
|
|
|
|
### Test página de creación de usuario
|
|
|
|
```py
|
|
def test_create_user_page(self):
|
|
"""Test the create user page works."""
|
|
url = reverse('admin:core_user_add')
|
|
res = self.client.get(url)
|
|
|
|
self.assertEqual(res.status_code, 200)
|
|
```
|
|
|
|
### Actualizar clase `UserAdmin` para que use los campos personalizados
|
|
|
|
[app/core/admin.py](./app/core/admin.py)
|
|
|
|
```py
|
|
class UserAdmin(BaseUserAdmin):
|
|
...
|
|
add_fieldsets = (
|
|
(None, {
|
|
'classes': ('wide',),
|
|
'fields': (
|
|
'email',
|
|
'password1',
|
|
'password2',
|
|
'name',
|
|
'is_active',
|
|
'is_staff',
|
|
'is_superuser',
|
|
)
|
|
}),
|
|
)
|
|
...
|
|
```
|
|
|
|
- Los test pasan
|
|
- Página para crear usuarios 
|
|
- Panel de usuarios del administrador 
|
|
|
|
## Documentación de la API
|
|
|
|
Es necesario tener acceso a una buena documentación para que los desarrolladores
|
|
puedan saber como usarla. Se documenta todo lo que sea necesario para usar la API
|
|
|
|
- Endopoints disponibles (paths)
|
|
- Métodos soportados `GET`, `POST`, `PUT`, `PATCH`, `DELETE`...
|
|
- Formateo de payloads (inputs). Parametros, Post en formato **JSON**
|
|
- Formateo de respuestas (outputs). Respuesta en formato **JSON**
|
|
- Proceso Autenticación
|
|
|
|
### Opiones de documentación
|
|
|
|
- Manual
|
|
- Documento de texto
|
|
- Markdown
|
|
- Automatizada
|
|
- Usa la metadata del código (comments)
|
|
- Genera páginas de documentación
|
|
|
|
## Autodocs de DRF
|
|
|
|
- Documentación Autogenerada (3rd party library)
|
|
- `drf-spectacular`
|
|
- Genera el "schema"
|
|
- Interfaz web navegable
|
|
- Test requests
|
|
- Maneja la autenticación
|
|
|
|
### Como funciona
|
|
|
|
1. Creación del archivo `schema`
|
|
2. Pasa el schema al GUI
|
|
|
|
### Open API Schema
|
|
|
|
- Estandar para describir APIs
|
|
- Popular en la industria
|
|
- Soportada por la mayoría de herramientas de documentación de API
|
|
|
|
### Ejemplo Schema
|
|
|
|

|
|
```
|
|
|
|
### Implementación DRF

|
|
|
## Autenticación
|
|
|
|
| Tipo de autenticación | Descripción |
|
|
| - | - |
|
|
| **Básica** | Envía usuario y password en cada request |
|
|
| **Token** | Usa un token en el encabezado HTTP |
|
|
| **JSON Web Token (JWT)** | Usa un token de acceso |
|
|
| **Sesión** | Usa cookies |
|
|
|
|
En esta app se utilza **Token** por:
|
|
|
|
- Balance entre simplicidad y seguridad
|
|
- Soporte por defecto por **DRF**
|
|
- Bién soportada por la mayoria de clientes

end

```
|
|
|
|
#### Pros del uso de Token
|
|
|
|
- Soporte por defecto
|
|
- Simple de usar
|
|
- Soportada por todos los clientes
|
|
- Evita enviar datos de usuario/password en cada request
|
|
|
|
#### Cons del uso de Token
|
|
|
|
- El token debe ser seguro
|
|
- Requiere hacer peticiones a la base de datos
|
|
|
|
### Login out
|
|
|
|
- Sucede en el lado del cliente
|
|
- Borra el token
|
|
|
|
### Test token API
|
|
|
|
Agregar tests en
