Target case is photos app: when visiting the tags category, all systemtags of the whole cloud are retrieved. In subequent steps the next tag is requested until the browser view is filled with tag tiles (i.e. previews are requested just as well). With this approach, we incorpoate the dav search and look for user related tags that are used by them, and already returns the statistics (number of files tagged with the respective tag) as well as a file id for the purpose to load the preview. This defaults to the file with the highest id. Call: curl -s -u 'user:password' \ 'https://my.nc.srv/remote.php/dav/systemtags-current' \ -X PROPFIND -H 'Accept: text/plain' \ -H 'Accept-Language: en-US,en;q=0.5' -H 'Depth: 1' \ -H 'Content-Type: text/plain;charset=UTF-8' \ --data @/home/doe/request-systemtag-props.xml With request-systemtag-props.xml: <?xml version="1.0" encoding="UTF-8"?> <d:propfind xmlns:d="DAV:"> <d:prop xmlns:oc="http://owncloud.org/ns" xmlns:nc="http://nextcloud.org/ns"> <oc:id/> <oc:display-name/> <oc:user-visible/> <oc:user-assignable/> <oc:can-assign/> <nc:files-assigned/> <nc:reference-fileid/> </d:prop> </d:propfind> Example output: … <d:response> <d:href>/master/remote.php/dav/systemtags/84</d:href> <d:propstat> <d:prop> <oc:id>84</oc:id> <oc:display-name>Computer</oc:display-name> <oc:user-visible>true</oc:user-visible> <oc:user-assignable>true</oc:user-assignable> <oc:can-assign>true</oc:can-assign> <nc:files-assigned>42</nc:files-assigned> <nc:reference-fileid>924022</nc:reference-fileid> </d:prop> <d:status>HTTP/1.1 200 OK</d:status> </d:propstat> </d:response> <d:response> <d:href>/remote.php/dav/systemtags/97</d:href> <d:propstat> <d:prop> <oc:id>97</oc:id> <oc:display-name>Bear</oc:display-name> <oc:user-visible>true</oc:user-visible> <oc:user-assignable>true</oc:user-assignable> <oc:can-assign>true</oc:can-assign> <nc:files-assigned>1</nc:files-assigned> <nc:reference-fileid>923422</nc:reference-fileid> </d:prop> <d:status>HTTP/1.1 200 OK</d:status> </d:propstat> </d:response> … Signed-off-by: Arthur Schiwon <[email protected]>
- uses DAV search approach against valid files joined by systemtag selector - reduced table join for tag/systemtag search - supports pagination - no changes to the output formats or similar Example request body: <?xml version="1.0"?> <oc:filter-files xmlns:d="DAV:" xmlns:oc="http://owncloud.org/ns" xmlns:nc="http://nextcloud.org/ns" xmlns:ocs="http://open-collaboration-services.org/ns"> <d:prop> <d:getcontentlength/> <d:getcontenttype/> <d:getetag/> <d:getlastmodified/> <d:resourcetype/> <nc:face-detections/> <nc:file-metadata-size/> <nc:has-preview/> <nc:realpath/> <oc:favorite/> <oc:fileid/> <oc:permissions/> <nc:nbItems/> </d:prop> <oc:filter-rules> <oc:systemtag>32</oc:systemtag> </oc:filter-rules> <d:limit> <d:nresults>50</d:nresults> <nc:firstresult>0</nc:firstresult> </d:limit> </oc:filter-files> Signed-off-by: Arthur Schiwon <[email protected]>
