I've searched around on Google before posting this and didn't found
anything useful. So, feel free to point me to a URL that answers this
is you find one.
I have a Category class. Categories have Datapoints and Categories. I
want to JSON-ify this deeply nested tree structure, but it fails at
the second level.
Does anyone know how to configure the json_serializer so that it
traverses past the first depth of associations?
I configured it like this: Category.plugin :json_serializer, :include
=> {:categories => {:include => Category.columns +
[:datapoints]}, :datapoints => {:include => Datapoint.columns}}
Here's a simple example of one category (classcat_id => 1010138) that
has a subcategory (classcat_id => 1010140). That subcategory has a
single datapoint:
[
{
"json_class": "Category",
"class_id": 10010,
"class_parent": null,
"class_name": "Manual Test Cases",
"class_tag": "JWH_TEST_CASE",
"classcat_id": 1010138,
"classcat_parent": null,
"classcat_class": 10010,
"classcat_name": "Imported Data",
"categories": [
{
"json_class": "Category",
"class_id": 10010,
"class_parent": null,
"class_name": "Manual Test Cases",
"class_tag": "JWH_TEST_CASE",
"class_description": null,
"class_keywords": null,
"class_can_publish": 1,
"class_is_active": 1,
"classcat_id": 1010140,
"classcat_parent": 1010138,
"classcat_class": 10010,
"classcat_tag": "TEST_IMPORT_CIRC_OUTPUT",
"datapoints": [
"#<Datapoint:0x6e5cbebb>"
]
}
],
"datapoints": [ ]
}
]
