Collaboration resources

Mockup/spec

#11015 (comment)

Implements #11015

UI

ToDo

Backend

• Allow apps to register their provider classes
• Add iconClass to Resources
• Limit calling resource providers by the resource type
• Add Link to resource
• Renaming collections
• Serach for existing collections
• x] Properly iterate over database until we find some collections

Frontend

• Create new collections in the files sidebar
• List existing collections and their resources
• Add to existing collections
• Remove resources from collections
• Add readableName to Resources (so a resource of type files is translatable and can be used in the ui like "Link to a file")
• Rename collections

Documentation

Registering resources in the frontend

OCP.Collaboration.registerType('files', {
// This function is called when the user selects the entry "Link to a file" in the multiselect input
action: () => {
return new Promise((resolve, reject) => {
OC.dialogs.filepicker('Link to a file', function (f) {
const client = OC.Files.getClient();
client.getFileInfo(f).then((status, fileInfo) => {
resolve(fileInfo.id)
}, () => {
reject()
})
}, false);
})
},
typeString: 'file',
typeIconClass: 'icon-files-dark'
});

Registering resource providers in the backend

• Implement OCP\Collaboration\Resources\IProvider
• ... TBD

@nickvergessen Is this ready by tomorrow evening? Could I help you somehow to get this in?

I've added a screencast of the current UI to the first post: #11871 (comment)

Please have a look @nextcloud/designers

@nickvergessen Please have a look as well 😉

• We still need to find a way to properly search for collections of a given user: https://github.com/nextcloud/server/pull/11871/files#diff-c0ede1133f7267a466a21eb7ee0e65ceR85
• Permission handling still needs to be sorted out
• Allow apps that don't have a dedicated selection UI (like the file picker) to register a search handler for their resources

Apart from that I think this is a good start for this feature.

Access cache should be working now for most things.
If you search the first time and a lot of collections with resources where created already, it is still bad, but we can't really help that.

@juliushaertl looking good generally, nice work! :) The icon-delete would better be icon-close X since it does not delete the file but only removes the connection?

[juliusknorr]

@nickvergessen There seem to be some issues with the query when fetching collections / creating collections. The frontend is already working for testing btw, just make sure to run npm install and npm run build for the core bundle as well as in apps/files_sharing/

@nickvergessen I tried to fix some more issues with the access cache joins. Seems to work now except for two issues, maybe you can have a look at those:

• When adding a resource to a collection the access cache entries for the collections resources get duplicated
• Access cache entries for collections are never added to the access cache

[nickvergessen]

Also todo:

• Add listener to group membership changes and purge for the user in that case.
• File sharing should purge access cache when a share is added/removed

[nickvergessen]

I think the backend should be ready now

[rullzer]

Lets do this!
