Managing user role assignments

Each user can be assigned a role for each application. This can be done via the API by updating the user and including the relationship 'user_to_app_to_role_by_user_id'. As an example let's say we want to assign user id 100 with a certain role for a certain app. If the role id is 7 and the app id is 5, the following would create the required relationship to assign that role to that user for that app.

PUT /api/v2/system/user/100?related=user_to_app_to_role_by_user_id  

{
	"user_to_app_to_role_by_user_id": [{
		"app_id": "5",
		"role_id": 7,
		"user_id": 100
	}]
}

To retrieve the role assignments, do a GET with relationship 'user_to_app_to_role_by_user_id'. The last one is the one we just created.

GET /api/v2/system/user/100?related=user_to_app_to_role_by_user_id  

{
	"id": 8,
	"user_to_app_to_role_by_user_id": [
		{
			"id": 23,
			"user_id": 8,
			"app_id": 1,
			"role_id": 7
		},
		{
			"id": 24,
			"user_id": 8,
			"app_id": 2,
			"role_id": 7
		},
		{
			"id": 25,
			"user_id": 8,
			"app_id": 3,
			"role_id": 7
		},
		{
			"id": 26,
			"user_id": 8,
			"app_id": 4,
			"role_id": 7
		},
		{
			"id": 31,
			"user_id": 8,
			"app_id": 5,
			"role_id": 7
		},
		{
			"id": 32,
			"user_id": 8,
			"app_id": 6,
			"role_id": 7
		}
	]
}
