I've got a master entity (node) that users edit, and I've got an entity reference on it. I'd like to be able to edit a field on the referenced entity on that master referencing entity's edit form.
Is there a module for this? Or can somebody just give me a general sense of a good way to accomplish this?
I know I can create a custom form element with hook_form_alter, then use a form_submit function, and then use entity_metadata_wrapper to load and save values.
That seems cumbersome, is there a better way to do this?
