Reference value pair
This module provides a new field type that combines an entity reference with a free text value, simplifying the process of storing a related entity alongside a descriptive value. It is useful for scenarios like associating units of measurement with numeric values, where the units are stored as separate entities.
The reference value pair combines an entity reference with a free text value field in one new field type.
Site builders often end up using field collection or entity reference modules when all they want to do is store a value and a reference (e.g. to a taxonomy term).
This module bundles the two things, a reference to some entity and a value together in one field. It can reference any entity, the value field is a simple text field.
One typical use is storing a measurement with its unit where the units are stored in a taxonomy (e.g 50 liter, 20 cm, 80 %).
