Relationship Attributes - Intro¶
In the previous chapters we discussed how to manage databases with tables that have relationships by using fields (columns) with foreign keys pointing to other columns.
And then we read the data together with
select() and using
.join() to connect it.
Now we will see how to use Relationship Attributes, an extra feature of SQLModel (and SQLAlchemy) to work with the data in the database in way much more familiar way, and closer to normal Python code.
When I say "relationship" I mean the standard dictionary term, of data related to other data.
I'm not using the term "relation" that is the technical, academical, SQL term for a single table.
And using those relationship attributes is where a tool like SQLModel really shines. ✨
