Breeze URL generation for REST API and navigation properties - breeze

Question

Ive been trying to use breeze with third party RESTful API - the API expects parameters of two types - deep linking like - localhost/request/5 for single entities (ie. request with id = 5) and parametrised queries using JSON encoded in URL (transformed by breeze with no problem).
The main problem is to make breeze to create request with URL such as:
localhost/request/{id}
not JSON encoded GET, while using breeze query "withParameters( {workorderid: id})"
And the second part of problem is using syntax like:
var query = breeze.EntityQuery
.from('request')
.withParameters(parameters)
.expand('requestDetails');
To query for two entities - main - request - and secondary - requestDetails (with deffered on access querying for value of the secondary object).
The result should be like on this image:

My model is defined by hand with two entities:
metadataStore.addEntityType({
shortName: "request",
namespace: "servicedesk",
dataProperties: {
workorderid: {
dataType: DT.Identity,
isPartOfKey: true
},
ignorerequest: {
dataType: DT.Boolean
}
},
navigationProperties: {
requestDetails: {
entityTypeName: "requestDetails:#servicedesk",
isScalar: true,
associationName: "request_requestDetails",
foreignKeyNames: ["workorderid"]
}
}
});
metadataStore.addEntityType({
shortName: "requestDetails",
namespace: "servicedesk",
dataProperties: {
workorderid: {
dataType: DT.Identity,
isPartOfKey: true
},
group: {
dataType: DT.String
},
description: {
dataType: DT.String
}
},
navigationProperties: {
request: {
entityTypeName: "request:#servicedesk",
isScalar: true,
associationName: "requestDetails_request",
foreignKeyNames: ["workorderid"]
}
}
Ive found example of this: https://github.com/Breeze/breeze.js.labs/blob/master/breeze.ajaxrestinterceptor.js , it looks like i can change url generation by intercepting ajax calls, can this be done for angular.breeze adapter?

I don't fully understand your question. What query are you having trouble with? Please edit your answer so we can help.
BUT I do see what looks like a metadata problem with your definition of the request type's requestDetails navigation property. Both the property name and the semantics suggest this should return a collection but you've defined it as a scalar.
requestDetails: {
entityTypeName: "requestDetails:#servicedesk",
isScalar: true, // <-- HUH?
associationName: "request_requestDetails",
foreignKeyNames: ["workorderid"]
}
I think you want isScalar: false,
