See [1], extracted from [2] But, AFAIK, with the current API, it is not possible to define this last pattern (at least for JS and iOs, confirmed by Matzew). When doing a read we can pass an id option but as mentioned in the doc, this id will always be append to the endpoint. Well, it is possible - but in a very (IMO) ugly way: https://gist.github.com/matzew/6ab432e437b9a017a21d

IMO, we should be able to support this pattern but for now I'm not really sure how to specify this in our API, so if you have any ideas feedback this thread has been made for you ! Suggestion: Enhance the read function - example: https://gist.github.com/matzew/04f069dfbed2cc77a8b4

I'll leave that decision to others. It would be easy enough for JS to just provide this as an object representing the nesting that I would just translate to a URI but it may not be that easy for others.

I like the idea but I will more see that has a method/function for the pipelineManager (and will be easier to implement in JS, I think) : var myParentPipe = Aerogear.Pipeline({name:"parentPipe"}).pipes.parentPipe var myChildPipe = Aerogear.Pipeline.fromParent(myParentPipe, {options} )

Hi team, on the last couple of days I have been playing with the idea on how to support nested path in resources (a.k.a subresources). I am more keen in the idea to treat the nested resources as full-time citizens. That is, treat the nested resource as a Pipe.

I came up with the following proposal (showing here in iOS) For demonstration I use an imaginative Soccer API e.g. soccer.org/leagues/{id}/teams/{id}/players when expanded with sample {ids}: soccer.org/leagues/seattle/teams/trebuchet/players During registration of the "parent pipe" (leagues) we specify the nested resources for this Pipe using the "setNestedPipes" config option. Internally the Pipeline during the setup of this pipe creates the corresponding nested pipes, initialising their URL accordingly. e.g. ----- AGPipeline* pipeline = [AGPipeline pipelineWithBaseURL:BASE_SOCCER_APP_URL]; id<AGPipe> leagues = [pipeline pipe:^(id<AGPipeConfig> config) { [config setName:@"leagues"]; [config setNestedPipes:[@"teams", @"players"]; // an array of nested resources for this pipe

}]; ----- A new "pipe" method is added in the pipeline with params the Parent ID's of this nested resource. Once returned you have a fill Pipe to invoke operations on. ----- soccer.org/leagues/seattle/teams/trebuchet - > [[pipeline pipe:@"teams" pathParams:@[@"seattle"]] read:@"trebuchet"] ... soccer.org/leagues/seattle/teams/trebuchet/players/foo - > [[pipeline pipe:@"players" pathParams:@[@"seattle", @"trebuchet"]] read:@"foo"] .. ----- Wdyt?

On Thu, Mar 28, 2013 at 1:03 PM, Christos Vasilakis <cvasilak(a)gmail.com&gt; wrote: Hi team, on the last couple of days I have been playing with the idea on how to support nested path in resources (a.k.a subresources). I am more keen in the idea to treat the nested resources as full-time citizens. That is, treat the nested resource as a Pipe. I agree w/ Luke - interesting proposal I came up with the following proposal (showing here in iOS) For demonstration I use an imaginative Soccer API e.g. soccer.org/leagues/{id}/teams/{id}/players when expanded with sample {ids}: soccer.org/leagues/seattle/teams/trebuchet/players During registration of the "parent pipe" (leagues) we specify the nested resources for this Pipe using the "setNestedPipes" config option. Internally the Pipeline during the setup of this pipe creates the corresponding nested pipes, initialising their URL accordingly. e.g. ----- AGPipeline* pipeline = [AGPipeline pipelineWithBaseURL:BASE_SOCCER_APP_URL]; id<AGPipe> leagues = [pipeline pipe:^(id<AGPipeConfig> config) { [config setName:@"leagues"]; [config setNestedPipes:[@"teams", @"players"]; // an array of nested resources for this pipe I would read the nested pipes here as: * soccer.org/leagues/{id}/teams * soccer.org/leagues/{id}/players which does not match the above URL samples, you gave;

}]; ----- A new "pipe" method is added in the pipeline with params the Parent ID's of this nested resource. Once returned you have a fill Pipe to invoke operations on. ----- soccer.org/leagues/seattle/teams/trebuchet - > [[pipeline pipe:@"teams" pathParams:@[@"seattle"]] read:@"trebuchet"] ... Hrm..... I am confused... What is the name of the first argument? Also the path params, not sure about them…

I think this proposal differs from how we currently read a specific entry: (soccer.org/leagues/seattle) [leaguesPipe read:@"seattle" success:callback failure:othercallback]; So i guess ... the above would return details about the "Seattle League", right?

Now... I think... If I wanted a "sub"/"nested" pipe, from that leagues pipe (e.g. to work with teams in the "Seattle Leaguue" ... I think there are two ways... a) use the Pipeline as it's factory (I guess that's what you proposed) b) use the actual pipe to create a nested pipe, by leveraging the available information Here is, I think, how the b) could look for this URL: id<AGPipe> allTeamsInSeattlePipe = [leaguesPipe subPipe:@"teams" for:@"seattle"]; Now we have a subPipe that has this (inherited) URL: -> soccer.org/leagues/seattle/teams And, if I want to issue a a read against "soccer.org/leagues/seattle/teams/trebuchet" would look like: [allTeamsInSeattlePipe read:@"trebuchet" success:callback failure:othercallback]; Now, imagine the API could also return the owners of a certain lagues - the "sub pipe creation" could be done like: Here is, I think, how the b) could look for this URL: id<AGPipe> allOwnersInNewYorkPipe = [leaguesPipe subPipe:@"owners" for:@"newyork"]; Reading details about Mr. Brown (some owner in the list, that has the ID 19) would be like: [allOwnersInNewYorkPipe read:@"19" success:callback failure:othercallback]; So... this would match a read to: "soccer.org/leagues/newyork/owners/19" Does that make sense ? Any thoughts ?

Two thoughts.... 1) the 'original' leaguesPipe has no clue about the subpipes, right ? 2) should a pipe offer a 'getter' for all it's sub pipes ?

Thought a bit more about it and chatted with friends, the issue with the sub pipes is: it adds state and is perhaps an API construct that is a bit hard to understand (see all the discussions here) Not sure - but currently we can access "kid resources", with our API - right ? https://gist.github.com/matzew/6ab432e437b9a017a21d Perhaps it's better to just keep it that way? This has the benefit of using an established and know API, the different pipes are accessible via the pipeline object; And the code is not too much code; it's simply an explicit pipe ...

My concern was more when we had a Pipe of type <Post> and a readForResource(String property) method.

The type information of the property isn't available unless we can infer it from the Post object.

you have a comments collection on the post but no comments data in the response then the value for getComments will just be null.

Hey, Like paging, could we start 2 gists : one with a side to side techno samples and another one with high level Specs ? I start a bit to get lost in this thread :)

Just one remark when reading the last messages, one "must have" is to be able to retrieve all the comments for a post without EVER retrieving the post record, so /posts/1/comments will retrieve all the comments for post 1 but will actually never call posts/1 : in this covered in your last examples ? (spec could be : "by-pass parent GET resource" Seb On Tue, Apr 9, 2013 at 9:03 AM, Matthias Wessendorf <matzew(a)apache.org&gt; wrote: On Mon, Apr 8, 2013 at 7:57 PM, Summers Pittman <supittma(a)redhat.com&gt; wrote: ----- Original Message ----- | From: "Matthias Wessendorf" <matzew(a)apache.org&gt; | To: "AeroGear Developer Mailing List" <aerogear-dev(a)lists.jboss.org&gt; | Sent: Monday, April 8, 2013 1:22:19 PM | Subject: Re: [aerogear-dev] [Aerogear Pipeline] Support for nested endpoints | | OK, with the following server API: | | http://some.server.com/posts/1 | http://some.server.com/posts/1/comments | (and NO 'comments' collection on the ' http://some.server.com/posts/1 ' | response) | | Does this (today) 'myPipe.read(1)' already read the specific comments ( | http://some.server.com/posts/1/comments ) ?? | | ======= JAVA API ======= | Class Post: | - string: id; | - string: title; | - string: postContent; | - List<Comment> comments; | Class Comment: | - string username; | - string comment; | | Or would the IMPL expect an 'embedded' _comments_ collection on the response | of "GET http://some.server.com/posts/1 " ?

Hi I've prepared a document[1] that collectively describes the different approaches discussed in this thread for supporting the nested resources. It is split in two sections, ones that don't require modification to the existing API and ones that do Please have a look and let me know if I miss sth or interpret one approach wrong.

Hi I've prepared a document[1] that collectively describes the different approaches discussed in this thread for supporting the nested resources. It is split in two sections, ones that don't require modification to the existing API and ones that do Please have a look and let me know if I miss sth or interpret one approach wrong.
