New Example: replace spaces with underscores as user types

[jaymorgan]

I can't seem to wrap my head around this. I want to be able to replace spaces with underscores in a field as someone types. Seems like it should be easy to do but I'm not able to out it together. Is this already addressed somewhere?

You could probably use ng-mask for this: http://angular-formly.com/#/example/very-advanced/ng-mask

I want it to actually change the value in the model though. This would only alter how the value is displayed, right?

Ah, yes, that's true. You'll want to look into the new parsers property that utilizes the $parsers api from angular. It's not very well documented and there's no example yet, but here's the issue that describes how it works: formly-js/angular-formly#368
