Angular ng-init assignment inside of a template

I need to initialize an object in my view and assign a reference to it.

Can I achieve this by using ng-init? Is it an assignment by value or reference?

<ANY ng-init="objA = objB"> ... </ANY>

Any help will be appreciated!

Move assignment to controller init() method.

ng-init is directive that have a very lot of side effects and hardly to trace it down. For example: when you use ng-init in directive template for creating/editing item and you assign some model value in it - you will achieve problem with editing that actually should use already existing value.

As well side effect of it is executing few times when you add ng-if.

Usage ng-init in templates are your own risk.

Right way: controller data should be defined at start of module - in any case any view started in order: $state -> resolve() -> controller -> template -> directive. It's not a good idea to fool yourself with not existing data until it will be created by magic.

In case of repeaters when you have for example empty {} and you need to display it like possibility to fill yet empty input, as I mentioned - you need to run function on init that can define empty or extend existing model by passing actual model.
