# Litestar-Django
2+
3+
Django model support for Litestar, implemented via Litestar [DTOs](https://docs.litestar.dev/latest/usage/dto/index.html).
4+
5+
```python
6+
from litestar import get, Litestar
7+
from litestar_django import DjangoModelPlugin
8+
from django.db import models
9+
10+
class Author(models.Model):
11+
name = models.CharField(max_length=100)
12+
13+
14+
class Genre(models.Model):
15+
name = models.CharField(max_length=50)
16+
17+
18+
class Book(models.Model):
19+
name = models.CharField()
20+
author = models.ForeignKey(Author, on_delete=models.CASCADE, related_name="books")
21+
genres = models.ManyToManyField(Genre, related_name="books")
22+
23+
24+
@get("/{author_id:int}")
25+
async def handler(author_id: int) -> Author:
26+
return await Author.objects.prefetch_related("books").aget(id=author_id)
27+
28+
29+
app = Litestar([handler], plugins=[DjangoModelPlugin()])
30+
```
31+
32+
This minimal setup will provide serialization of Django objects returned from handlers,
33+
complete with OpenAPI schema generation.
34+
35+
## Installation
36+
37+
```bash
38+
pip install litestar-django
39+
```
40+
41+
## Usage
42+
43+
### Directly constructing a DTO
44+
45+
```python
46+
from litestar import get
47+
from litestar_django import DjangoModelDTO
48+
from app.models import Author
49+
50+
@get("/{author_id:int}", dto=DjangoModelDTO[Author])
51+
async def handler(author_id: int) -> Author:
52+
return await Author.objects.prefetch_related("books").aget(id=author_id)
53+
```
54+
55+
### Automatically creating DTOs via the plugin
56+
57+
```python
58+
from litestar import get
59+
from litestar_django import DjangoModelPlugin
60+
from app.models import Author
61+
62+
@get("/{author_id:int}")
63+
async def handler(author_id: int) -> Author:
64+
return await Author.objects.prefetch_related("books").aget(id=author_id)
65+
66+
app = Litestar([handler], plugins=[DjangoModelPlugin()])
67+
```
68+
69+
### Creating a model instance from a DTO
70+
71+
```python
72+
from typing import Annotated
73+
from litestar import post
74+
from litestar.dto import DTOConfig
75+
from litestar_django import DjangoModelDTO
76+
from app.models import Author
77+
78+
@post(
79+
"/",
80+
sync_to_thread=True,
81+
dto=DjangoModelDTO[
82+
Annotated[
83+
Author,
84+
# exclude primary key and relationship fields
85+
DTOConfig(exclude={"id", "books"})
86+
]
87+
],
88+
return_dto=DjangoModelDTO[Author],
89+
)
90+
async def handler(data: Author) -> Author:
91+
await data.asave()
92+
return data
93+
```
94+
95+
## OpenAPI
96+
97+
Full OpenAPI schemas are generated from models based on their field types:
98+
99+
### Type map
100+
101+
| Field | OpenAPI type | OpenAPI format |
102+
|------------------------|--------------|----------------|
103+
| `models.JSONField` | `{}` | |
104+
| `models.DecimalField` | `number` | |
105+
| `models.DateTimeField` | `string` | `date-time` |
106+
| `models.DateField` | `string` | `date` |
107+
| `models.TimeField` | `string` | `duration` |
108+
| `models.DurationField` | `string` | `duration` |
109+
| `models.FileField` | `string` | |
110+
| `models.FilePathField` | `string` | |
111+
| `models.UUIDField` | `string` | `uuid` |
112+
| `models.IntegerField` | `integer` | |
113+
| `models.FloatField` | `number` | |
114+
| `models.BooleanField` | `boolean` | |
115+
| `models.CharField` | `string` | |
116+
| `models.TextField` | `string` | |
117+
| `models.BinaryField` | `string` | `byte` |
118+
119+
### Additional properties
120+
121+
The following properties are extracted from fields, in addition to its type:
122+
123+
124+
| OpenAPI property | From |
125+
|--------------------|----------------------|
126+
| `title` | `Field.verbose_name` |
127+
| `description` | `Field.help_text` |
128+
| `enum` | `Field.choices` |
129+
| `exclusiveMinimum` | `MinValueValidator` |
130+
| `exclusiveMaximum` | `MaxValueValidator` |
131+
| `minLength` | `MinLengthValidator` |
132+
| `maxLength` | `MaxLengthValidator` |
133+
134+
### Relationships
135+
136+
Relationships will be represented as individual components, referenced in the schema.
137+
138+
139+
## Lazy loading
140+
141+
> [!IMPORTANT]
142+
> Since lazy-loading is not supported in an async context, you must ensure to always
143+
> load everything consumed by the DTO. Not doing so will result in a
144+
> [`SynchronousOnlyOperation`](https://docs.djangoproject.com/en/5.2/ref/exceptions/#django.core.exceptions.SynchronousOnlyOperation)
145+
> exception being raised by Django
146+
147+
This can be mitigated by:
148+
149+
1. Setting `include` or `exclude` rules to only include necessary fields ([docs](https://docs.litestar.dev/latest/usage/dto/1-abstract-dto.html#excluding-fields))
150+
2. Configuring nested relationships with an appropriate `max_nexted_depth`
151+
([docs](https://docs.litestar.dev/latest/usage/dto/1-abstract-dto.html#nested-fields))
152+
3. Using [`select_related`](https://docs.djangoproject.com/en/5.2/ref/models/querysets/#select-related)
153+
and [`prefetch_related`](https://docs.djangoproject.com/en/5.2/ref/models/querysets/#prefetch-related)
154+
to ensure relationships are fully loaded
155+
