Sanic filter

Required:

• Python: >=3.9
• SQLAlchemy: >=2.0.20

Optional

• Sanic: >=23.3.0
• Dataclasses

Installation

pip install sanic-filter

Description

You define the fields you want to be able to filter on as well as the type of operator

name: str = Query(option='ilike')

You can make some field mandatory

class MyFilter(Filter)
	name: str = Query(option='ilike', required=True)

Query

?name=moon,sun

sqlAlchemy

SELECT * FROM table WHERE table.name LIKE :name_1 OR table.name LIKE :name_2"

Supported operators:

• like
• ilike
• in
• ==
• !=

If you want to search by JSON fields

#SqlAlchemy model

properties = Column(JSON, nullable=True)

Filter supports one level of nesting

color: str = Query(option='ilike’, json_column='properties', required=True)

Query

?name=moon,sun

sqlAlchemy

SELECT * FROM table WHERE table.name LIKE :name_1 OR table.name LIKE :name_2"

Returned fields

You can specify the returned fields of the models Filter

fields: str = Query(option='returned_fields')

It will look like this SqlAlchemy model

class Car(BaseModel):
    __tablename__ = "cars"

    id = Column(UUID(as_uuid=True), primary_key=True, default=uuid.uuid4)
    name = Column(String, nullable=True)
    order = Column(String, nullable=True)
    properties = Column(JSON, nullable=True)

Query

?name=moon,sun

sqlAlchemy

SELECT * FROM table WHERE table.name LIKE :name_1 OR table.name LIKE :name_2"

The search for fields is performed automatically, if the field has the same name, use model name

sqlalchemy models

class Car(BaseModel):
    __tablename__ = "cars"

    id = Column(UUID(as_uuid=True), primary_key=True, default=uuid.uuid4)

class Garage(BaseModel):
    __tablename__ = «garages»

    id = Column(UUID(as_uuid=True), primary_key=True, default=uuid.uuid4)

filter

id: str = Query(option='ilike', required=True, model=Car)

routers

query.filter(select(Car, Garage))

If you want to return fields with the same name, but from different models, use the alias parameter id from Car

car_id: str = Query(option='ilike’, alias=‘id’, model=Car)

garage_id: str = Query(option='ilike', alias=‘id’, model=Garage)
