Using the CData ODBC Driver for Trello in PyCharm

The CData ODBC Drivers can be used in any environment that supports loading an ODBC Driver. In this tutorial we will explore using the CData ODBC Driver for Trello from within PyCharm. Included are steps for adding the CData ODBC Driver as a data source, as well as basic PyCharm code to query the data source and display results.

To begin, this tutorial will assume that you have already installed the CData ODBC Driver for Trello as well as PyCharm.

Add Pyodbc to the Project

Follow the steps below to add the pyodbc module to your project.

1. Click File -> Settings to open the project settings window.
2. Click Project Interpreter from the Project: YourProjectName menu.
3. To add pyodbc, click the + button and enter pyodbc.
4. Click Install Package to install pyodbc.

Connect to Trello

You can now connect with an ODBC connection string or a DSN. See the Getting Started section in the CData driver documentation for a guide to creating a DSN on your OS.

Trello uses token-based authentication to grant third-party applications access to their API. When a user has granted an application access to their data, the application is given a token that can be used to make requests to Trello's API.

Trello's API can be accessed in 2 different ways. The first is using Trello's own Authorization Route, and the second is using OAuth1.0.

• Authorization Route: At the moment of registration, Trello assigns an API key and Token to the account. See the Help documentation for information on how to connect via the Authorization route.
• OAuth Route: Similar to using Authorization, OAuth creates an Application Id and Secret when you create your account. See the Help documentation for information on how to to connect.

Below is the syntax for a DSN:

[CData Trello Source]
Driver = CData ODBC Driver for Trello
Description = My Description
APIKey = myApiKey
Token = myGeneratedToken
InitiateOAuth = GETANDREFRESH

Execute SQL to Trello

Instantiate a Cursor and use the execute method of the Cursor class to execute any SQL statement.

import pyodbc

cnxn = pyodbc.connect('DRIVER={CData ODBC Driver for Trello};APIKey = myApiKey;Token = myGeneratedToken;InitiateOAuth = GETANDREFRESH;')
cursor = cnxn.cursor()
cursor.execute("SELECT BoardId, Name FROM Boards WHERE Name = 'Public Board'")
rows = cursor.fetchall()
for row in rows:
 print(row.BoardId, row.Name)

After connecting to Trello in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to Trello data as if it were a standard database. If you have any questions, comments, or feedback regarding this tutorial, please contact us at [email protected].
