Drupal 7 Rules - Set value of multiple value reference field (user reference)

Question

I have a cck content type with a multi value reference field. Using rules, I am trying to populate these reference fields when users create a different content type (for example an event and I want to keep adding user references for people that view the event -- this is an example.)

My issue right now is that I can fetch the entity to set the user reference (using a loop of users), but I can only set the first field. How do I move to the next field of the fetched entity and set it to the next user in the loop list?

I imagined that as long as I was in the loop, for each item in the loop, a set data value on the reference field would move to the next field but it simply overwrites the first one.

I see that the particular reference field I'm trying to set values for is an array (fetched-entity:field-blah:0 etc). Since I cannot pick for example item [0], I thought fetched-entity:field-blah without the delta would keep shifting to the next. It does not.

I'm thinking there is a way for me to loop through the deltas in the fetched entity as I loop through the list?

Any help appreciated.

Answer 1

1. Install next modules:
   • Conditional Rules
   • Rules Bonus Pack
2. Create a rule for "Content is viewed".
3. Set conditions , like "content is type"
4. Create a loop and set its name, in the data selector choose the field(not the deltas) like [node:field-alumnos-curso]
5. Create an action inside the loop(do not "set data value"), just select "add item to the list" and the value will be the list name or loop name.
6. Remember create a action "Save an entity".

Its long since the question asked. Currently this can be done very easily.

1. Load a list of entity objects. I used a VBO View.
2. Set a data value. Parameter: Data: [node:field-your-user-ref-field], Value: [entity-list-you-loaded]
3. Save the entity

Its as simple as this. I am using this very successfully.
