Is there any endpoint in alfresco that allows applying the aspects in bulk

bip1989

Hello community 

As the title says, i was searching in the community content about any available endpoints to apply aspects in bulk on several nodes in one or more sites. I have 4-5 aspects which i have added to my content model which i want to apply to old nodes

Is there anything available already or do i need to create a custom WebScript or something?

Appreciate any hint/guidance

As far as i know, there are no ootb rest api which can be used for your use case. However, there is a way to add/remove aspects to one node.

You can see details here:

For applying aspects to multiple nodes to a specific site or on all the available sites, you can do following:

1- Create a java backed or repo (js) webscript which will search for the nodes in site for missing aspect.
2- You can target one site at a time or you can list all sites and iterate on iterate
3- Search query would be something like:

PATH:"/app:company_home/st:sites/cm:test-site/cm:documentLibrary//*" AND (TYPE:"cm:content" AND NOT ASPECT:"xyz:aspectName" AND NOT ASPECT:"cm:lockable") [Here, cm:test-site is the site short name.]

You can limit the search to a specific folder and custom content types as well.

4- Iterate on resulted nodes and apply the aspect using NodeService (when using java backed webscript) or call addAspect on node (node.addAspect("xyz:aspectName")).

Here is a sample repo (js) webscript, you can take reference from it and tweak it as per your need, It allows applying aspect to all the sites based on search query:

apply-aspect.get.js

main();

function main(){
	var aspectName = args["aspectName"];
	var contentType = args["contentType"];
    var skipCount = (args["skipCount"]==null || args["skipCount"]==undefined)?0:args["skipCount"]; //defaults to 0, if argument is not passed.
	var maxCount = (args["maxCount"]==null || args["maxCount"]==undefined)?100000:args["maxCount"]; //defaults to 100000, if argument is not passed.
	
	var successfullNodes = [];
	var erroredNodes = [];
	
	var query = 'PATH:"/app:company_home/st:sites//*" AND TYPE:"'+contentType+'" AND NOT ASPECT:"'+aspectName+'" AND NOT ASPECT:"cm:lockable"';
	
	var page = {
			skipCount : parseInt(skipCount),
			maxItems : parseInt(maxCount)
	};

	var searchQuery = {
			query : query,
			language : "lucene",
			page : page
	};
	
 	logger.log("Query for search: "+query)
 	var nodes = search.query(searchQuery);
 	logger.log("Resulted Nodes: "+nodes.length)

	for each(node in nodes) {
		try {
			if(!node.hasAspect(aspectName)){
				node.addAspect(aspectName);
				successfullNodes[node.nodeRef] = "Aspect '"+aspectName+"' applied successfully to: " +node.name;
			}
		} catch(excp) {
			logger.log("Failed to apply aspect due to: "+excp.message);
			erroredNodes[node.nodeRef] = "Aspect '"+aspectName+"' could not be applied to: " +node.name+", due to: "+excp.message;			
		}
	}
	//Put the result in model so that we can display it in a template
        model.successfullNodes = successfullNodes;
	model.erroredNodes = erroredNodes;
}
