Introduction
The packages allows you to programmatically create ER diagrams. The pacakges is simple, but it should help you generate ER diagrams like the one provided by Chen.
Installation
pip install yaerrrr
Example
A single ER can be generated as follows:
import yaerrrr
class TestEr(yaerrrr.AbstractYaerrrrScript):
def generate_er(self, context: 'yaerrrr.YaerrrContext') -> "yaerrrr.ErDiagram":
er = context.er
er.add_entity(name="authors", fields=[
er.generate_primary_id_key(),
])
er.add_entity(name="books", fields=[
er.generate_primary_id_key()
])
er.add_1_to_0_n("authors", "books", "writes")
return er
def main():
x = TestEr()
x.run("output.svg")
if __name__ == "__main__":
main()
and it outputs (for now):
1 maintainer
Metadata
1 maintainer
