When working with SQLAlchemy, the need to convert row objects into Python dictionaries often arises. This article provides a workaround for this requirement, focusing on the specific version of 0.5.6.
The code sample illustrates the challenge. Attempting to iterate over column-value pairs using dict(row) or dict(u) for each query result throws an exception due to the non-iterable nature of SQLAlchemy objects.
To overcome this hurdle, we can leverage the internal __dict__ attribute of the SQLAlchemy object. By iterating over each query result u and accessing its __dict__ attribute, we can access the column name and value pairs in a dictionary format. The following code demonstrates this solution:
for u in session.query(User).all(): print u.__dict__
This workaround allows for easy iteration through column-value pairs, providing a simple and effective way to convert SQLAlchemy row objects into Python dictionaries.
