Deno 2.2 Improves Dependency Management and Expands Node.js Compatibility
Deno 2.2 enhances Node.js compatibility, improves dependency management, adds OpenTelemetry support, and expands linting and task automation for developers.
Please read
UPGRADE-v2.0.md <https://github.com/graphql-python/graphene/blob/master/UPGRADE-v2.0.md>
__
to learn how to upgrade to Graphene 2.0
.
A SQLAlchemy <http://www.sqlalchemy.org/>
__ integration for
Graphene <http://graphene-python.org/>
__.
For instaling graphene, just run this command in your shell
.. code:: bash
pip install "graphene-sqlalchemy>=2.0"
Here is a simple SQLAlchemy model:
.. code:: python
from sqlalchemy import Column, Integer, String
from sqlalchemy.orm import backref, relationship
from sqlalchemy.ext.declarative import declarative_base
Base = declarative_base()
class UserModel(Base):
__tablename__ = 'department'
id = Column(Integer, primary_key=True)
name = Column(String)
last_name = Column(String)
To create a GraphQL schema for it you simply have to write the following:
.. code:: python
from graphene_sqlalchemy import SQLAlchemyObjectType
class User(SQLAlchemyObjectType):
class Meta:
model = UserModel
class Query(graphene.ObjectType):
users = graphene.List(User)
def resolve_users(self, info):
query = User.get_query(info) # SQLAlchemy query
return query.all()
schema = graphene.Schema(query=Query)
Then you can simply query the schema:
.. code:: python
query = '''
query {
users {
name,
lastName
}
}
'''
result = schema.execute(query, context_value={'session': db_session})
