Instance Method Details

#input ⇒ Object

Determine which type of input to used based on the field. If the field is a column, use the column’s type to determine an appropriate field type. If the field is an association, use either a regular or multiple select input (or multiple radios or checkboxes if the related :as option is used). If it’s not a column or association, but the object responds to field, create a text input. Otherwise, raise an Error.
