javascript - How do I access a particular model in the templateHelper of a Collection View (or Layout)? -


roughly have this:

my collection; //a collection of models ids   layout = backbone.marionette.layout.extend({     templatehelpers: {         myfunc: function() {              //this.items array of serialized models in collection         }     } })  layout = new layout({     collection: collection,  })

the problem in myfunc() can see model data in collection: available array this.items. there no key cannot this.items.get("the_one_i_want").

how can access individual model in case?

( in case doesn't suit use composite view , item view , put template helper on item view. )

correct me if i'm misunderstanding, seems me maybe you're looking "container methods" of in marionette, listed here: http://marionettejs.com/docs/backbone.marionette.html under "container methods".

so if have collection of models ids, rather than

this.items.get('the_one_you_want')

you'd write like

this.items.findbyindex('my_index')

i've never used findbyindex , there's little warning "this not guaranteed stable index." can search few other things, including cid , model itself.

again, may not understand situation, hope provides help... ian

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
