Re: referential integrity

Hello

I have been reading the docs, looking for a way to acheive referential integrity as it is done in RDBMS.

For instance, if I want to constraint the value of atribute title to a set of value, so that any modification to a value not in the list would be denied. Let's say the set of legal values could be stored in the directory, ad objects of a dedicated class;

How can it be done? slapo-refint is not about denying changes, slapo-constraint can only enforce regex matching.. Is there anything else I missed?

Write a new overlay to do what you want...
