Calc field reference to related app
I need to pull in a value from a specific item record in a related app. App A is where I'm pulling from, App B is where I'm pulling into. App A has 10 records and I want the value of Field C from record 1 only. I would appreciate guidance on what is my calculation formula, please.
when you call the referenced items through @all of field c you get them as an array. The first element in this array is always the "oldest" item (it's the one with the lowest Unique ID). You get this item with
@all of field c
The youngest item you get with
@all of field c[@all of field c.length-1]
Thanks Rainer. I should have noted that the desired record in app A is not in a fixed order. In fact, the record I'm referencing is in App B as a related/linked field. I need to extract the value of Field C within that matching record. Specifically:
App A, record x, Field C value is what I want to obtain
App B contains a relationship field linked to "App A" records
I want to add a calculation field in App B to obtain Field C value when the linked record in App B matches the same record in App A.
I hope that helps clarify. Thanks again,
The matching criterion is a field in the record. My example is a database managing projects, deliverables, and tasks (each of these is an app, and each contains multiple records. Records are linked/related between apps (ie, a project has multiple deliverables and each deliverable has multiple tasks). Projects are the parent, deliverable = child, tasks = grandchild.
Each app has a field called "title" and "priority". The title of one project is "Project A", which has 3 deliverables ("1", "2,", "3"). "Project A" has a priority field value of "1". Within "Project A", "Deliverable 1" priority field value is "2". I want to add a field in the Deliverable App called "Project Priority" that references the priority field in "Project A". So Deliverable "1" has 2 priority fields: its own deliverable priority = 2 and its referenced project priority = 1.
Thank you again for your time and help!
If a Delivarable is connected to only 1 Project it 's simply
@all of priority.toString()
All Deliverables which are related to Project A will show the same value ("1" in your example) in their field "Project Priority".
What I don't understand is:
"App A has 10 records and I want the value of Field C from record 1 only." (in your 1. posting). - @all of gets values omly form the 1 linked Project.
and: "when the linked record in App B matches the same record in App A." (in your 2. posting) - there is nothing to match it there's only 1 Project item related.
Hi Michael and Rainer
I have a similar need. In App 'Contact' I wish to search for the text 'xyz' in a text field 'Communication' in all related items from App 'Email' (in same Workspace).
In Contact, I use (thanks to Rainer):
var text = @All of Communication [Email via Contact (incoming) type]
text.indexOf("xyz") > -1 ? "Yes, XYZ found" : "No, not XYZ"
But, even when I refresh a Contact that has this text 'xyz' in the Communication field of a related Email, the calculation does not find a match. In the Email App, I set up a similar calculation field to find 'xyz' in the Communication field on each email item, and this works fine. My guess is that in the Contact App I am not searching through all related Email items? I get an array as Rainer describes above, so maybe the search syntax must be different? Hope you have a good idea Rainer :)
