I have these features that I would like to transform and group into JSON output:
package_idpackage_nameresource_nameresource_url1Package AResource 1http://www.resource-A1.com1Package AResource 2http://www.resource-A2.com1Package AResource 3http://www.resource-A3.com2Package BResource 1http://www.resource-B1.com2Package BResource 2http://www.resource-B2.com3Package CResource 1http://www.resource-C1.com3Package CResource 2http://www.resource-C2.com3Package CResource 3http://www.resource-C3.com4Package DResource 1http://www.resource-D1.com
The resulting dataset should consist of 4 features, one feature for each package.
For each feature or package I need an attribute containing the package data in JSON format.
For example the value of the JSON attribute for first feature should be:
{
"id" : "1",
"name" : "Package A",
"resources" : [
{"name" : "Resource 1", "url" : "http://www.resource-A1.com"},
{"name" : "Resource 2", "url" : "http://www.resource-A2.com"},
{"name" : "Resource 3", "url" : "http://www.resource-A3.com"},
]
}
For the second one:
{
"id" : "2",
"name" : "Package B",
"resources" : [
{"name" : "Resource 1", "url" : "http://www.resource-B1.com"},
{"name" : "Resource 2", "url" : "http://www.resource-B2.com"}
]
}
I think I should probably use the JSONTemplater transformer, combining a root template with a sub template, but I cannot seem to figure out how it is done. Any help would be greatly appreciated.
