A TODO list using Model Classes

Show and Tell
1

Here is the app I presented at today’s Anvil User Group meeting! It’s a pretty simple TODO-list app, but it’s implemented entirely with Model Classes (look ma, no Server Modules!).

Clone it here to take a look: Anvil | Login

Notable features:

  • There are no Server Modules! All privileged operations happen via the model (including a @server_method)
  • All security and access control is in the model
  • The is_overdue property on the model class separates the logic (what counts as an overdue task) from the presentation (display overdue tasks in red - which happens in the data bindings of the row template)
  • The model is client-writable, so all the DB updates happen directly in client code
  • Buffering to edit items or draft new items

I’d suggest starting with the Models module, then working your way through Form1, then the row template in the DataGrid, then EditItem itself (which is 100% data bindings and no other code).

If you have any questions, feel free to ask!
