Automatically find model classes in modules

[jayqi]

Would be a nice convenience feature if users could specify a module (or multiple modules) and have erdantic loop through its namespace and find any data model classes.

[zamiramir]

Workarround for a module which contains classes of pydantic BaseModel:

import erdantic as erd
from pydantic import BaseModel
import some_module
import inspect

objs = set()
for name, obj in inspect.getmembers(some_module):
    if inspect.isclass(obj) and issubclass(obj, BaseModel):
        objs.add(obj)
        diagram = erd.create(obj)
        diagram.draw(f"diagram_{name}.svg")
diagram = erd.create(*objs)
diagram.draw("diagram_all.svg")

Keep up the good work! 🥇
