This plugin allows you to tell a field to instantly apply a block (defined in validators) to a field when you create a new instance of a model, or update an existing record.
I didn’t want content editors to have to click the add block button, rather I wanted the model to display all requried fields from the get go.
In an ideal world there would be a new field Type, that just applied a block to a model for you. But for now you can use this plugin to apply validators to modular text fields.
Now in the market place and working as much as I think it needs to. I’m using it on a production project so will likely keep it reasonably uptodate.
