Is there a way to add a server-side hook in an ROP setup that allows you to perform an action before a record is committed or before it is fetched to alter a flag on the record before it is sent to the client?
Here is my use-case: I have records that need to be electronically signed. My implementation of the signing process involves calculating a hash of a record's data (and the data of important foreign records) and attaching that hash to the signature record. On fetch a signed record would then validate its signature record's hash to ensure no data has changed since it was signed. Currently this is all done on the client side before committing to the server or after fetching. In reality this is bad practice as it gives the client the power to decide how the signature is generated and validated. I would like to have the hashing and validation code on the server to take that power away from the client. My hope is that I can put a pre-commit hook on the server objects that checks for a link to a Signature object and performs the hashing and storage of the hash. Upon fetch I would like the server-side to validate the hash and set a flag on the Signature object that is then sent to the client. Does this sound feasible? Thanks, Adam
