在sqlalchemy中，如何导入另一个表上具有外键的现有表

Question

I have two Tables as bellow:

table series :

+-------------+
| Field       |
+-------------+
| series_id   |
| title       |
+-------------+

table season :

+-------------+
| Field       |
+-------------+
| season_id   |
| title       |
| version     |
| duration    |
| series_id   |
+-------------+

In season , series_id as foreign key referees from series(series_id)

Now I want load these two table via sqlalchemy. Is that possible to build a one-to-many relationship between these two tables so that I can access all seasons object of one series?

Answer 1

Yes you can! The series_id field of the season table will be a foreign key to the series table. To get all seasons of a particular series, you will query the 'season' table for all entries which have a particular series_id.

Look at this: http://docs.sqlalchemy.org/en/latest/orm/tutorial.html#querying
