Adds two rendering options.
render :super¶ ↑
This syntax skips all template overrides and goes directly to the provided ActiveScaffold
templates. Useful if you want to wrap an existing template. Just call super!
render :active_scaffold => #{controller.to_s}, options = {}+¶ ↑
Lets you embed an ActiveScaffold
by referencing the controller where it’s configured.
You may specify options for the embedded scaffold. These constraints have three effects:
* the scaffold's only displays records matching the constraint * all new records created will be assigned the constrained values * constrained columns will be hidden (they're pretty boring at this point)
You may also specify options for the embedded scaffold. These only do 1/3 of what constraints do (they only limit search results). Any format accepted by Sequel::Model.find is valid.
Defining options lets you completely customize the list title for the embedded scaffold.
