How to use SQLAlchemy ORM to access EventBrite Data in Python
Create Python applications and scripts that use SQLAlchemy Object-Relational Mappings of EventBrite data.
The rich ecosystem of Python modules lets you get to work quickly and integrate your systems effectively. With the CData API Driver for Python and the SQLAlchemy toolkit, you can build EventBrite-connected Python applications and scripts. This article shows how to use SQLAlchemy to connect to EventBrite data to query EventBrite data.
With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live EventBrite data in Python. When you issue complex SQL queries from EventBrite, the CData Connector pushes supported SQL operations, like filters and aggregations, directly to EventBrite and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).
Connecting to EventBrite Data
Connecting to EventBrite data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.
Start by setting the Profile connection property to the location of the EventBrite Profile on disk (e.g. C:\profiles\EventBrite.apip). Next, set the ProfileSettings connection property to the connection string for EventBrite (see below).
EventBrite API Profile Settings
To use authenticate to EventBrite, you can find your Personal Token in the API Keys page of your EventBrite Account. Set the APIKey to your personal token in the ProfileSettings connection property.
Follow the procedure below to install SQLAlchemy and start accessing EventBrite through Python objects.
Install Required Modules
Use the pip utility to install the SQLAlchemy toolkit and SQLAlchemy ORM package:
pip install sqlalchemy
pip install sqlalchemy.orm
Be sure to import the appropriate modules:
from sqlalchemy import create_engine, String, Column
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker
Model EventBrite Data in Python
You can now connect with a connection string. Use the create_engine function to create an Engine for working with EventBrite data.
NOTE: Users should URL encode the any connection string properties that include special characters. For more information, refer to the SQL Alchemy documentation.
engine = create_engine("api:///?Profile=C:\profiles\Eventbrite.apip&ProfileSettings='APIKey=my_api_token'")
Declare a Mapping Class for EventBrite Data
After establishing the connection, declare a mapping class for the table you wish to model in the ORM (in this article, we will model the Events table). Use the sqlalchemy.ext.declarative.declarative_base function and create a new class with some or all of the fields (columns) defined.
base = declarative_base()
class Events(base):
__tablename__ = "Events"
Id = Column(String,primary_key=True)
Name = Column(String)
...
Query EventBrite Data
With the mapping class prepared, you can use a session object to query the data source. After binding the Engine to the session, provide the mapping class to the session query method.
Using the query Method
engine = create_engine("api:///?Profile=C:\profiles\Eventbrite.apip&ProfileSettings='APIKey=my_api_token'")
factory = sessionmaker(bind=engine)
session = factory()
for instance in session.query(Events).filter_by(Status="live"):
print("Id: ", instance.Id)
print("Name: ", instance.Name)
print("---------")
Alternatively, you can use the execute method with the appropriate table object. The code below works with an active session.
Using the execute Method
Events_table = Events.metadata.tables["Events"]
for instance in session.execute(Events_table.select().where(Events_table.c.Status == "live")):
print("Id: ", instance.Id)
print("Name: ", instance.Name)
print("---------")
For examples of more complex querying, including JOINs, aggregations, limits, and more, refer to the Help documentation for the extension.
