Accessing Models of Other Entities in a Custom Dynamic Handler

[fberbert]

I have an entity, and in its JSON file under clientDefs, I defined a dynamic handler:

"dynamicHandler": "arc-custom-plugin:handlers/dynamic/unit",

Inside this handler, I have access to the this.recordView.model object, which has methods like get, set, save, fetch, etc.

The this object contains model and recordView, which are related to the scope of the entity in question.

My handler starts with the following code:

define('arc-custom-plugin:handlers/dynamic/unit', ['dynamic-handler', 'arc-custom-plugin:lib/module-js-functions'], function (Dep, Utils) {
...

My question is, how can I access models of other entities within this local scope code to use in my logic? Is there a way to inject some kind of App object in the list of dependencies?

Thank you.

The max that is possible to access is this.model.collection.models and this.model.collection.parentModel, and only in certain circumstances. There's no connection between different views by design. Though, you can establish it by using some 3rd object that will serve as an intermediate. You can register a service (with frontend dependency injection) and require it in different pieces of your frontend. This requires using ext-template as it needs the transpiling step.

Thanks for the guidance. I managed to solve my issue by creating a hook for the entity in question and injecting the EntityManager into the class, which allowed me to access other entities.
