Schema inspection for PostgreSQL
Schema inspection for PostgreSQL (and potentially others in the future).
Inspects tables, views, materialized views, constraints, indexes, sequences, enums, functions, and extensions.
Limitations: Function inspection only confirmed to work with SQL/PLPGSQL languages so far.
Get an inspection object from an already opened SQLAlchemy session or connection as follows:
from schemainspect import get_inspector from sqlbag import S with S('postgresql:///example') as s: i = get_inspector(s)
The inspection object has attributes for tables, views, and all the other things it tracks. At each of these attributes you’ll find a dictionary (OrderedDict) mapping from fully-qualified-and-quoted-name-of-thing-in-database to information object.
For instance, the information about a table books would be accessed as follows:
>>> books_table = i.tables['"public"."books"'] >>> books_table.name 'books' >>> books_table.schema 'public' >>> [each.name for each in books_table.columns] ['id', 'title', 'isbn']
Documentation is a bit patchy at the moment. Watch this space!
Install with pip:
$ pip install schemainspect
To install psycopg2 (the PostgreSQL driver) at the same time as well:
$ pip install schemainspect[pg]
