How to implement the update only some properties of change

The documentation is not clear on that matter :)

From the JDBDatabase you get a JDBCollection, then create a JDBView, then create a JDBQuery from that view.

From a JDBQuery you can

• modify all docs with allAndModify:
• modify docs within limit with allInRange:andModify:
• or modify only the first doc with firstAndModify:

Those methods all take a JDBModifyOperation code block that take the NSMutableDictionary document to be modified, then expect you return options to tell JsonDB what type of modification you want to do

You can see this in action here:
