Django model properties that are also lookup expressions.

```python
from lookup_property import lookup_property
from django.db import models
from django.db.models import Value
from django.db.models.functions import Concat

class Student(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)

    @lookup_property
    def full_name():
        return Concat("first_name", Value(" "), "last_name")
```
```pycon
>>> from myapp.models import Student
>>> from lookup_property import L
>>>
>>> Student.objects.create(first_name="John", last_name="Doe")
>>> student = Student.objects.filter(L(full_name="John Doe")).first()
>>>
>>> student.full_name
'John Doe'
```
