According to http://infoqubeim.com/drupal5/?q=node/128, auto-assignment rules can be triggered as follows:

A: Update target field when the current field is added (initially no value in the current field)

M: Update target field when the current field is modified (initially there is a value in the current field)

E: Update target field when the current field is erased (the current field had a value and you deleted it)

Say you already have a value in the current field for an item, but now you want to create a new auto-assign value to push a value to a target field, or set a tag for that same item, without modifying the existing value in the current field for that item? (As if the value were just added to the current field.) Is there a way to do this?

I entered an auto-assignment rule to set a tag, to see if it would be applied where items already contained a value for that field. Didn't work. Also tried the Recalculate button, but that applies only to row equations.

Did you try Edit > Touch ?

It is supposed to do just that...

see 2. Edit Menu

Hi Pierre, thanks for your reply. I hadn't tried Edit/Touch, so I gave it a try as follows.

I have a Y/N field named "USB Flash Drives". As a test, for that field I entered the following auto-assignment rule in Manage Fields:

A:#USB_Flash_Drives|E:#USB_Flash_Drives=0

I had already created the tag USB_Flash_Drives in the tags pane.

Then I highlighted all my items for which the USB Flash Drive field is checked, and then I did Edit/Touch.

I hoped that all these items would now be tagged with the #USB_Flash_Drives tag, but it didn't happen.

Am I doing something wrong?

It works here...

Remember that Edit > Touch "touches" the selected cells, not the selected items. So you must select the appropriate grid column

Can you try that ?

In the example above, I added the column "USB Flash Drives" to my grid, and all the TLIs appeared checked. Then I highlighted all the TLI cells in that column, did Edit > Touch, but none of the items were tagged with the #USB_Flash_Drives tag. I also tried right-clicking the column header and clicking Select Column before I did Edit > Touch - same result, no tagging. I tried refreshing the tags list to see if the tagging would appear, no luck.

I added the AA rule A:[Test] to see if that work, didn't work whether I Touched the whole USB Flash Drives column or just a single cell.

The AA rule does work if I check/uncheck the USB Flash Drives field manually - the corresponding tag does get checked/unchecked. It's just the Edit/Touch method that's not working.

The Touch command does the equivalent of a Modify event auto-assign, so replace A: with AM: and it should work just fine

Also from Field Management Dialog - Equations

Auto-assign rules can also set tags: use #TagName=-1 or #TagName=0 to set / unset tags

Thanks Pierre, I got it working. "AM:#USB_Flash_Drives" didn't work, but "AM:#USB_Flash_Drives=-1" did.

I was following this from http://infoqubeim.com/drupal5/?q=node/4328 section 6:

So using a simple auto-assign rule, it is possible to update 1 or more tags whenever a field is changed, hence linking fields and tags.
To do so, in the field auto-assign section enter:
A:#TagName | E:#TagName=0

I gathered from this the "-1" might be assumed, but maybe not?

Indeed...

Improved in v116i:

New: Fields: In auto-assign equations, simpler syntax to set/unset tags. Details here
