Using OnDevice to set the value of a custom column
I wonder if anyone could give me some help. I've just begun to explore customising Calibre and I'm finding it tricky; I spotted a throw away comment in a thread (sorry can't find it now) where the poster said breezily that they used a custom column to record which books are loaded onto their Kindle so that they know what's what even when the device isn't connected.
Just what I want I thought.
I found this post http://www.mobileread.com/forums/sho...03&postcount=6 and that of course work well to do it manually. But I feel sure that I should be able to set it automatically using the ondevice() funtion explained in the user manual and mentioned here http://www.mobileread.com/forums/sho...6&postcount=15
I guess I need a composite column but does it need to behave like a tag or not; or does it not matter? I presume I need to put the expression into the template box - but what exactly do I need to type into there?
Ideally I should like my new column to be updated when I connect my device so that if I delete things from the kindle itself the value of the column reflects that, and of course the value needs to persist after I unplug the device.

There is no (easy) way to automatically record "ondevice" in a way that persists after you disconnect the device. You can do such things in a plugin, but I don't know of one that does it.
The usual solution is to select all books and set the custom column to false using edit metadata (bulk). Next search for ondevice:true while the device is connected, select all and use edit metadata to set the custom column to true.

Make a True/False column (mydevice) in the Library if one does not exist.
Connect your device and wait for the device task to finish.
Stage 1) un-mark previous saved status for missing/removed from device books.
Enter this search:
ondevice:false and formats:true
1) Clear previous values if it was previously used by Selecting All (ctrl+A).
Bulk Meta-data edit: Custom metadata tab: set mydevice to No
Stage 2) Mark those found on the device.
Set the search:
Bulk Meta-data edit: Custom metadata tab: set mydevice to Yes
you have now saved your current status

Since ondevice does not persist if you restart Calibre, I use the Reading List plugin to keep track of what books are on my device when disconnected.
Instead of 'send to device' shortcut I remap it to send to 'reading list'. Next setup the program to manually/automatically 'Replace device with list, add new items only' (this adds/removes except overwrites because in my case it would remove the 'im_reading' collection the kobo uses).
When disconnected you call up the reading list, add/remove books to sync later. Reading List can also add a tag so you can do fancy stuff like column coloring, etc.
