无法使用文件夹名称字段来过滤HP QC REST API中的资源

Question

I don't expect to get an answer on this but if anyone can help it would be greatly appreciated.

We're using HP Application Lifecycle Management 12.2 (ALM or QC/QualityCenter as it's called). I'm trying to retrieve test resources from the project using the REST api but I suspect I've come across a defect in the API.

I'm trying to filter the response by using a query, and any other query works fine but when I try to use the 'folder-name' field it fails with the following message:

Failed to set params in the parametrized query

It doesn't matter what format I try to escape the query with, I've tried the following: /resources/?query={folder-name[%27folder%27]} /resources/?query={folder-name['folder']} /resources/?query=%7bfolder-name%5b%27folder%27%5d%7d

I've also reproduced this on an 11.52 QC instance so it's not just our environment. I've double checked the customization collection using the ?can-filter=true param and folder-name is supposed to be filterable.

I'm currently using the parent-id for filtering instead which works but it requires me to do another request to get the parent-id first which I would like to refrain from.

Any suggestions, patches? Thanks

Answer 1

As I wrote in the comments, the error is reproducable here, and I agree that it is strange. The folder-name exists as a field in resource, and should be filterable. It seems to be a bug.

But there is another approach that I offer as a substitute solution. The resource entity offer a relation directly to the folder entity, and you can get the exact result you were looking for, by using a cross join with that table:

/resources/?query={resource-folder.name['folder']}

This is probably too late to help you with your work, but it might help others.
