Error Code 306

[RoosterJuice]

Hi folks,

 

I've been developing a web front end using Django for our office's filemaker database.

 

Occassionally when there are a lot of simultaneous submissions to the database I get an "error 306:Record modification ID does not match"

 

I cannot find anywhere on the internet what this error may mean.  Any help with the meaning of this error would be a great help to me!

 

Thanx!

That's odd - two questions re 306 within hours of each other - unless this is really the same one as on the FMP-Experts list...

 

Are these inserts or updates?

 

If updates, this means what it says - along with the -recid that is FileMaker's unique internal id, there is -modid that is a count of the times the record has been updated. A well written web system will acknowledge that there is a time lag between retrieving a record for modification, and posting the results back. During this time period, someone else may have modified the record - those modifications would be over written if the -modid is not checked...

 

If inserts - that should never happen.
