    vRO Action driven Dynamic inputs

    pezh0re Novice

      Is there a way to add a dynamic number of inputs based on a vRO action output? I'm working on a vRO workflow that will ask a user for vCenter tags to apply to a VM - but the tagging categories may change as time goes on. I'd prefer not to hard code anything if I can help it.

       

      I currently have a workflow that populates predefined list/answers from actions (leveraging the VAPI), but I'd like to get to the next step and have the user provide input for each of the vCenter tag categories.

          No, vRO presentation does not allow dynamic creation of input fields, you can only show/hide existing inputs.

           

          So one possible option is to create the maximum anticipated number of inputs upfront, and then dynamically show/hide part of them. This would work if there is a sane upper limit on the number of inputs.

           

          Another possible option is to implement sort of a loop, and in each loop iteration collect one or few inputs using a user interaction element. This might work, with some assumptions (eg. that the client option to automatically pop up a user interaction form is turned on).

            Would it be possible to use dynamic types somehow to accomplish this? Create a dynamic type with the various tag categories, then have that be a static input for a workflow?

              No, dynamic types serve a different purpose. What you are describing here sounds closer to so called 'composite types', but they are also not so flexible to allow dynamic creation of their fields at runtime.

                I do have a workflow that we use to assign a single tag to one or many VM's at a time.  In the presentation of this we ask for VM Name, Tag Category & Tag Value.  The Tag Category is populated by an action that returns all the Tag Categories and sorts them for inclusion in a drop down.  So while this may not be exactly what you are looking for, it may be of some use.

                 

                Action Scripting

                "

                throw "'endpoint' parameter should not be null";

                }

                 

                 

                // Fetch tags and tag categories

                var client = endpoint.client(); 

                var category = new com_vmware_cis_tagging_category(client); 

                var categories = category.list();

                var sourceTagCats = new Array();

                //Exclude Source tags in the "agency" category

                for each(sourceTagCatId in categories){

                sourceTagCat = (new com_vmware_cis_tagging_category(client)).get(sourceTagCatId);

                if(sourceTagCat.name === 'agency'){

                agencyTagCatId = sourceTagCat.id;

                }

                else{

                sourceTagCatObj = new Object();

                sourceTagCatObj.name = sourceTagCat.name;

                sourceTagCatObj.id = sourceTagCat.id;

                sourceTagCats.push(sourceTagCatObj.name);

                }

                }

                sourceTagCats = sourceTagCats.sort()

                return sourceTagCats

                "

                 

                Then in the presentation tab of the workflow, you can set a property to the input attribute as "Predefined List of Elements"  See the Screenshot below.
