You definitely do not want to pass 'entry' as a parameter on the url.
Every database object needs some kind of unique key id just for situations
like this.
Maybe you could use the insertDate as a key (it's probably unique within
this context) but it would be better to add a key, perhaps a sequence number
so that goalToAchieve_id + seq is the PK.
