object references an unsaved transient instance - save the transient instance before flushing or set cascade action for the property to something that would make it autosave. Type:xxx, Entity: xxx


This is the exception information reported by NHibernate.TransientObjectException,

Mainly, because one table and another table have a primary foreign key relationship,

When saving, the foreign key ID is written by itself, not the entity object obtained from the table.

Causes the throw of an exception.

Solution:

Let's see it yourself




Previous:mvc returns javascrip{filter}t script
