So I followed this tutorial to kombine fastapi & peewee: link
And due to this tutorial i got those models (peewee):
class User(peewee.Model):
email = peewee.CharField(unique=True, index=True)
hashed_password = peewee.CharField()
is_active = peewee.BooleanField(default=True)
class Meta:
database = db
class Item(peewee.Model):
title = peewee.CharField(index=True)
description = peewee.CharField(index=True)
owner = peewee.ForeignKeyField(User, backref="items")
class Meta:
database = db
And those basemodels (fastapi):
class PeeweeGetterDict(GetterDict):
def get(self, key: Any, default: Any = None):
res = getattr(self._obj, key, default)
if isinstance(res, peewee.ModelSelect):
return list(res)
return res
class ItemBase(BaseModel):
title: str
description: Optional[str] = None
class ItemCreate(ItemBase):
pass
class Item(ItemBase):
id: int
owner_id: int
class Config:
orm_mode = True
getter_dict = PeeweeGetterDict
class UserBase(BaseModel):
email: str
class UserCreate(UserBase):
password: str
class User(UserBase):
id: int
is_active: bool
items: List[Item] = []
class Config:
orm_mode = True
getter_dict = PeeweeGetterDict
I have this to call the api:
database.db.connect()
database.db.create_tables([User, Item])
database.db.close()
app = FastAPI()
def get_db(db_state=Depends(reset_db_state)):
try:
database.db.connect()
yield
finally:
if not database.db.is_closed():
database.db.close()
@app.get("/users/", response_model=List[schemas.User], dependencies=[Depends(get_db)])
def read_users():
return list(models.User.select()
This is the base. Now begins my problem / question:
If I call this request (GET "/users/"), I get the following JSON as a result (the data is imaginary its only about the structure)
[
{
"email": "123@test.com"
"id": 1
"is_active": 1
"items": [
{
"title": "item1"
"description": "placeholder"
"id": "1"
"owner_id": "1"
}
]
}
]
This is how it is supposed to be BUT i don't want it exactly like this. I want that I only get the user data, without its items.
So... my question:
How can I get the user data without loading the data of the items?
There is a simple way to do that, response_model_exclude is exactly what you are looking for.
@app.get("/users/", response_model=List[schemas.User], response_model_exclude={"items"}, dependencies=[Depends(get_db)])
def read_users():
return list(models.User.select()
