[Girder-users] Find a file with a given name in a Collection

[Zach Mullen]

Hi Brian,

Items actually keep track of what top-level resource they live under in
their model data.  This isn't exposed via the core web API, so you'd want
to expose it via a plugin that would create a new endpoint.  You could do
this (mostly) in the database, by using find() with a query like the
following:

results = self.model('item').find({
    'name': {'$regex': searchRegex},
    'baseParentType': 'collection',
    'baseParentId': collectionId
})
return list(self.model('item').filterResultsByPermission(results,
self.getCurrentUser(), level=AccessType.READ, limit=limit, offset=offset))


It would probably also be a good idea to add the relevant indexes to the
item collection to make such searching much faster.


HTH,
