Calculated field for content type based on dateOfIntroduction field

[Jeffrey Schultz]

Does dotCMS support the ability for me to add a calculated field to a Content Type that uses another field within that Content Type to convert a dateOfIntroduction timestamp into a label, such as Tier 1, Tier 2, etc.?

How would this be done so that the content data comes back with this field in the JSON?

Your question isn't perfectly clear, but I will take a stab at it.

If you are just using the backend, you can put in arbitrary js via a custom field that will allow for calculations and updates.

The js you use there can also talk to the API, to either read in other fields/structures or write back to the API.

If this is not enough, you can just write code in java or js or velocity (or some combination) and make *any* sort of app you like - dotCMS can work 'headless'. 

I can routinely do things like make an SQL query against my school db to build a list of 'active departments' for a drop down or something like that in the dotCMS backend that my users use and they do not notice.  

Now, 'out of the box' and 'without code', no, you cannot do what you are asking.

Thanks, Mark. I think your response answers my question. 

I just needed the ability to have a field that isn't editable, and that derives its value from another field within the Content Type to produce a label based on say a timestamp.
