Minimal database access library
Project description
Medial - minimal database assistance library
Medial is not an abstraction layer to magically make your classes persistent. it merely tries to alleviate some of the tedium, hopefully not by adding more tedium or new complexity.
Knowledge of SQL is still necessary, as well as the specific flavour(s) used. Medial currently supports SQLite and Postgres.
API documentation is available.
Example usage
import medial
class Thing(Persistent):
table = 'things'
key = 'name'
persistence = {
'name': {
},
'description': {
}
}
def __init__(self, name=None, description=None, new=False):
if name and not new:
# lookup
super().__init__(name)
else:
# new object
super().__init__()
self.name = name
self.description = description
# configure medial
medial.configure('file:///tmp/example.sqlite')
# lookup thing or create new thing
try:
# lookup
t = Thing(name='example')
except medial.exceptions.ObjectNotFound:
# create
t = Thing(name='example', new=True)
t.commit()
Status
Medial is in active development. Due to its minimal design, features you may expect (relations, for example) are easily implemented with regular SQL, but if/when new features are introduced (relations, for example), existing code will almost certainly continue to work.
Current features
- SQLite and Postgres
- Python enumerations
- Validation and setter override functions
Planned features
- Relations
