How to filter asset object attribute with AQL, to show subset of reference?

Frederic Wolf

Hi together,

I would like to know how I can filter an object attribute with AQL and use in the filter the value of another object attribute?

I have the following object types:

Schema: Employee
---------------------
Object Type: Employee
- Name (Label)
- Company (Reference to Company Object)
- Location (Reference to Location Object)

Schema: Company
--------------------
Object Type: Company
- Name (Label)
- Locations (Reference to Location, Cardinality 0 to unlimited)

Object Type: Location
- Company Name
- Address
** Has Inbound Reference of Company (see above)

There are of course several companies with even more locations. By the way, the object type Employee is subdivided into Internal and External Employees, but this is not important for the use case.

I would like to achieve that the selection of the location in the object Type: Employee is filtered based on the attribute Company.

I can set the AQL filter for the attributes.

The following static AQL filter works: 'object having inR(Name LIKE "Example Company")'.
--> As expected, this filter returns only the location objects that have an inbound reference where the name is like "Example Company".

However, I want to filter based on the Company object that is entered in the Employee object (bonus point: if no location is selectable when Company is not selected). This way I would have a dynamic filter.

I have already tried multiple variations:
Examples:

object having inR(Name LIKE ${Company})
object having inR(Name LIKE ${Company})
object having inR(Name LIKE ${Company.Name})

I am currently out of ideas and am curious if there is a solution for this or if this is not possible at all.

PS:
Also happy to suggest alternative ways I can achieve this. Sometimes you can't see the forest for the trees.

Hi @Frederic Wolf 

I think I understand what you are trying to achieve here as it sounds similar to something I have done that I have done with my Asset Types and Models.

So basically, you have:

Company A at Locations 1 2 and 3

Company B at Locations 1 3 and 4

Meaning some locations are exclusively Company A or B but some locations have employees from both Company A and B.

So being similar to how I have setup my Schemas, I would have a Company Object Type and each asset would be a Company Name.

I would then have a Locations Object Type and each Asset would be a Location Name. There would be an attribute on this, that links to Company Object Type. The cardinality could be multiple as Location 1 may be relative to Company A and B but Location 2 only for Company A.

Then over on my Employee or Asset Object Type I would have Attributes for Company and Location. Each linking to the relevant Schema and Object Type. Company would be a direct link to Company Schema. Location would be a direct link to Location schema however on the AQL Filter it would say Company = ${Company}.

This means that as you are filling in the Asset, you select Company attribute first in current schema. And then when you click the Location drop down, the list will only show Locations based on the Company you selected just prior to it. If no company is selected, then no locations will show.

 

I have done this same thing in my system with Asset Types and Models.

As an example: I have no Type Selected so my Model drop down shows No Options

When I select Type as HDW-Laptop, now you can see my Model drop down is Filtered to All Models with a Type as a Laptop (sorry my screenshot is weird. The drop down actually drops up, not down)

 

This is the Asset View showing all models with type HDW-Laptop:
