Does create_pydantic_model use optional fields by design

[scott2b]

In using a model created with create_pydantic_model as a request validator in a web application view, I am finding that the fields are not validated, vs creating my own schema subclassed from BaseModel which will complain, e.g., if the request data is missing fields.

I am trying to determine if I am doing something wrong, or if this is by design.

There's a parameter you can pass to your columns called required. By default it's False. create_pydantic_model uses this to determine if a field is optional or not.

class MyTable(Table):
    name = Varchar(required=True)

MyTableModel = create_pydantic_model(MyTable)

# name is now required:
MyTableModel()
>>> Error! 

It's not documented well - we need to add a section to this page explaining it:

Ah, that makes total sense. I should have thought of that. Thank you.

I've updated the docs now to include this.
