formatting - How to format the values of a model in Marionette Backbone View before rendering? -

if implement onbeforerender method no way access model values in order format them temporarily

ideally want format values before rendering without changing model values of course!

how it?

by checking link: http://derickbailey.github.io/backbone.marionette/docs/backbone.marionette.html

you find serializedata being used before rendering template

so overriding it, below can format object values way want before rendering

serializedata():any {         var obj = super.serializedata();          obj.totalenergy = math.round(obj.totalenergy).tofixed(0)          return obj     }
