I wanted a to-many relationship for attachments on multiple entities
(journals, payments,invoices, whatnot). In the end, I added that one
line model dependency and it work. My model defines an entity called
FileAttachment, which itself is modeled as a to-many for multiple
other entities. FileAttachment has only the to-one relationship to
ERAttachment as it seemingly requires based on what's documented. This
may add a little work in creating an extra entity before uploads can
happen, but it cleanly allows the two-many that I need.
