[英]How to merge all results of AQL into single document with custom properties
I have an AQL query traversing graph that always should return a fixed amount of documents from a unique set of collections.我有一个 AQL 查询遍历图,它总是应该从一组唯一的集合中返回固定数量的文档。 So each collection will occur only once and with one document only.
所以每个集合只会出现一次,并且只有一个文档。
I wish to merge them all into a single document under properties that reflects document's collection name.我希望将它们全部合并到反映文档集合名称的属性下的单个文档中。
Query as simple as:查询很简单:
FOR v IN ANY "vertex/key" edge_collection RETURN v
Returns a sample result as:返回示例结果为:
[
{
"_key": "123",
"_id": "foo/123",
"_rev": "_WYhh0ji---",
"foo_attribute": "lorem impsum"
},
{
"_key": "456",
"_id": "bar/456",
"_rev": "_WYhh2ny---",
"bar_attribute": "dolor sit amet"
}
]
That I wish to get like this:我希望得到这样的:
[
{
"foo": {
"_key": "123",
"_id": "foo/123",
"_rev": "_WYhh0ji---",
"foo_attribute": "lorem impsum"
},
"bar": {
"_key": "456",
"_id": "calendar/bar",
"_rev": "_WYhh2ny---",
"bar_attribute": "dolor sit amet"
}
}
]
PARSE_IDENTIFIER
function that gives document's collection name and key separatelyPARSE_IDENTIFIER
函数,该函数分别给出文档的集合名称和键Example:例子:
RETURN MERGE(
FOR v IN ANY "vertex/key" edge_collection
RETURN {[PARSE_IDENTIFIER(v).collection]: v}
)
