Marionette passed objects to module

Question

I have recently updated to Marionette JS version 2.4.7 after being on an older version of Marionette for a very long time.

I am initializing a module and want to pass two objects to this module , a model and another custom object foo .

layout = new FooBar.Layout
  model: options.model if options.model
  foo: options.foo if options.foo
options.loadRegion.show(layout)

The model comes through just fine in the initialize method of the FooBar module but the foo object is not coming through in the options object of the FooBar module no matter what I try, though it is appearing in the options object before I initialize FooBar.Layout (as seen above).

Am I doing something wrong in the new version of Marionette?

Answer 1

I realized the problem was with trying to run a conditional statement in an object property declaration, which does not work.

layout = new FooBar.Layout
  model: options.model if options.model
  foo: options.foo if options.foo

Removing the conditional statements works:

layout = new FooBar.Layout
  model: options.model
  foo: options.foo

Or declaring your object before creating the new Layout works, as well

opts = nil
opts.model = options.model if options.model
opts.foo = options.foo if options.foo

layout = new FooBar.Layout(opts)
