do I have to read the source for each object to learns its methods?
Yes, you will have to read the source code to see what methods are available.
I try to save this code data:
[{"uid":"1","name":["Andreas"]}]
where uid is a field and name is a array. But when I do db.setObject I obtain this error:
Modifiers operate on fields but we found a Array instead. For example: {$mod: {<field>: ...}} not
Anyone can help me to save in my format?
you need to wrap it like {"value": [{"uid":1,"name":["Andreas"]}]}
. Arrays are no (direct) instances of Objects; Thus not allowed to be used within db.setObject
.
EDIT: Actually [] instanceof Object === true
. It's just not allowed by the database clients since Arrays are no conventional key/value stores.
