Subject: [OASIS Issue Tracker] Commented: (ODATA-398) Define "GetByID" canonical function as a path segment
[ http://tools.oasis-open.org/issues/browse/ODATA-398?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33511#action_33511 ] Michael Pizzo commented on ODATA-398: ------------------------------------- yes, I wanted to define a convenience shortcut to make Hubert's brilliant solution more discoverable ;-) the advantage to making it a path segment is that we know from the path that it identifies a single resource (same as with a key lookup), so 1) $filter and $orderby don't apply 2) it can be returned as a single object, not as a collection containing a single object (another advantage over simply filtering using $it) > Define "GetByID" canonical function as a path segment > ----------------------------------------------------- > > Key: ODATA-398 > URL: http://tools.oasis-open.org/issues/browse/ODATA-398 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Improvement > Components: OData ABNF Construction Rules, OData Protocol , OData URL Conventions > Affects Versions: V4.0_CSD01 > Environment: [Proposed] > Reporter: Michael Pizzo > Fix For: V4.0_CSD02 > > > Ids are the primary way to reference an instance in OData; they are used in relationships, in deltas, and can take the place of instances in payloads. We recommend, but do not require that ids be dereferenceable. > Clients need a dependable way to get from an id to a reference, whether or not the reference is dereferencable. Although they could construct a query if they know the root set the id comes from, it would be useful and more discoverable to introduce a canonical query function, at the service root, for returning an instance given its id. > Note that, since the id is likely to contain illegal characters, we have to pass the id as a query option, and will need to double single quotes in reference > Options: > GET ~myservice/getbyid(@id)?@id='.....' > GET ~myservice/$getbyid?@id='.....' -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
