Added
- `one_or_none` parameter to FastCRUD `get` method (default `False`)
- `nest_joins` parameter to FastCRUD `get_joined` and `get_multi_joined` (default `False`)

Detailed Changes
`get`
By default, the `get` method in `FastCRUD` returns the `first` object matching all the filters it finds.
If you want to ensure the `one_or_none` behavior, you may pass the parameter as `True`:
python
crud.get(
async_session,
one_or_none=True,
category_id=1
)
`get_joined` and `get_multi_joined`
By default, `FastCRUD` joins all the data and returns it in a single dictionary.
Let's define two tables:
python
class User(Base):
__tablename__ = "user"
id = Column(Integer, primary_key=True)
name = Column(String)
tier_id = Column(Integer, ForeignKey("tier.id"))
class Tier(Base):
__tablename__ = "tier"
id = Column(Integer, primary_key=True)
name = Column(String, unique=True)
And join them with `FastCRUD`:
python
user_tier = await user_crud.get_joined(
db=db,
model=Tier,
join_on=User.tier_id == Tier.id,
join_type="left",
join_prefix="tier_",,
id=1
)
We'll get:
javascript
{
"id": 1,
"name": "Example",
"tier_id": 1,
"tier_name": "Free",
}
Now, if you want the joined data in a nested dictionary instead, you may just pass `nest_joins=True`:
python
user_tier = await user_crud.get_joined(
db=db,
model=Tier,
join_on=User.tier_id == Tier.id,
join_type="left",
join_prefix="tier_",
nest_joins=True,
id=1,
)
And you will get:
javascript
{
"id": 1,
"name": "Example",
"tier": {
"id": 1,
"name": "Free",
},
}
This works for both `get_joined` and `get_multi_joined`.
!!! WARNING
Note that the final `"_"` in the passed `"tier_"` is stripped.
What's Changed
- Reuse of `select` method in `FastCRUD`
- Skip count call when possible
- Add `one_or_none` parameter to FastCRUD `get` method
- Add `nest_joins` parameter to FastCRUD `get_joined` and `get_multi_joined`
