I wonder how I would implement the scheduler with different types of resources. At the moment I am already using the event, assignment and resource stores, which allow a many-to-many relationship between events and resources. I would like to implement this construct but with an additional resource type. So that I effectively have two combo boxes with an resource assignment in the event editor.

Is there any way to have multiple resource/assignment stores? I have already tried modelling the relationship in the event editor, but as far as I can tell, there is no array or object field type that would make this possible.

Thank you very much for your support!

This is not supported no, but if you explain in a bit more detail we should be able to give you some advice. You want to assign two sets of resources to a single event? And you cannot do this using our current multi-select resource combo?

So far I am using the following model:

class MyEvent extends EventModel {

  static get fields() {
    return [
      { name: 'resourceType2Id', type: 'string', persist: true },
    ];
  }
}

An as I wrote, I'm using the event, assignment and resource (for resourceType1) stores to map the many-to-many relationship between resource type 1 and events. But now I need to assign several resources of type 2 to an event, which means that I can no longer use the reference to a single ID in the event model.

It could still be done using one multi-assignment combo box, or you definitely want it done in two separate ones?

Yes, I think two combo boxes would be better, as the types should be semantically separated. Also, only the one type of resource should be displayed as columns.

Could you have one resource store with a custom modelClass introducing the resourceType (type 1 or type 2) and filter the stores of combo boxes depending on which resource is being assigned?

That would probably solve the problem with the different combo boxes. Is there also a way to filter the displayed resource columns? And how do you filter the stores of the combo boxes?

I hope this is exactly what you're looking for.

Hi pmiklashevich,

thanks for your reply. The example you provided helped a lot. In the example the "master" store was grouped by the type field, but my use case requires one type to be hidden entirely. How would could I solve this?

Hello.
If I understood you correctly, you can try to filter out records with certain type from the store:
