✨ Update AutoUi on schema change #192

Open ollyhensby opened 11 months ago

ollyhensby commented 11 months ago

Feature Request To make it possible for an AutoUi object to update based on a new schema passed.

Expected Behaviour Create AutoUi object.

from ipyautoui import AutoUi
from pydantic import BaseModel

class Stringy(BaseModel):
    stringy: str

ui = AutoUi(schema=Stringy)
display(ui)

Displays this UI object. image

Then setting schema

class Inty(BaseModel):
    inty: int

ui.schema = Inty.schema() OR ui.schema = Inty

Would display this on the same UI object. image

Use Case My use case for this is when using EditGrid: the value and schema can be set in the object, which updates the DataGrid, but the AutoUi object doesn't update leading to a mismatch between the columns (or rows) shown in the DataGrid and the fields in the AutoUi object. The only way this can be done is by re-instantiating the whole EditGrid object. It would be great to have an AutoUi schema setter that updates AutoUi object.

reviewing this again... I'm not 100% sure it is possible... this @classmethods init the form from schema / model: https://github.com/maxfordham/ipyautoui/blob/3421b2eb8fdb052d2f94aaf51e50fefdd3108ce1/src/ipyautoui/watch_validate.py#L133-L168

probs need to extract them out and make a tr.observe event to super().__init__() on change... not 100% it would work well though...
