Supertool changing sources of citations

Help

The script below tries to change the source of the selected citations to the source of the first citation selected. But, it doesn’t change the source. What am I doing wrong, please?

[Gramps SuperTool script file]
version=1
[title]
SuperTool-Citations
[category]
Citations
[initial_statements]
first = True
[statements]
if first:
	snew = source
first = False 
citation.source = snew
[filter]
[expressions]
source, citation,snew
[scope]
selected
[unwind_lists]
False
[commit_changes]
True
[summary_only]
False

Output:

ID	Value1	Value2	Value3
C05306 	Source[S01909] 	<gramps.gen.lib...	Source[S01909]
C12219 	Source[S00857] 	<gramps.gen.lib...	Source[S01909]

You can’t directly change the citation’s reference to its source, you have to use a method to do it, something like that in statements:

if first:
	snew = source.handle
	first = False 
citation.set_reference_handle(snew)

I’ve tested it, that’s working.

Thank you, as you say, it now works.

How could I have known the correct code without asking? Is it because Source is of type SourceProxy and so can’t be altered directly?

My references documents are principally these two:

You could also read posts tagged Isotammi (or supertool-script) on this Discourse

And, I’ve published this filters library, may be you could find some methods used in it interesting(?)

Not exactly. The Proxy is a working copy of the piece of the tree. Your script makes its changes to the Proxy copy. Then, once the script successfully competes AND you have the “Commit changes” the Proxy changes are committed to the main tree. If the script doesn’t successfully complete, the proxy changes simply go away.

Kari has been updating the Reference section of the SuperTool README.md file. It has a new chart that has the Proxy classes.
