Hi,
Which is right way to write documentation for Navigation table methods? For example for GetAirlinesTable:
// Data Source Kind description
TripPin = [
Authentication = [
Anonymous = []
],
Label = "TripPin Part 3 - Navigator"
];
// Data Source UI publishing description
TripPin.Publish = [
Beta = true,
Category = "Other",
ButtonText = { "TripPin Navigator", "TripPin Navigator" }
];
//
// Implementation
//
[DataSource.Kind="TripPin"]
shared TripPin.Feed = Value.ReplaceType(TripPinImpl, type function (url as Uri.Type) as any);
[DataSource.Kind="TripPin", Publish="TripPin.Publish"]
shared TripPin.Contents = Value.ReplaceType(TripPinNavTable, type function (url as Uri.Type) as any);
DefaultRequestHeaders = [
#"Accept" = "application/json;odata.metadata=minimal", // column name and values only
#"OData-MaxVersion" = "4.0" // we only support v4
];
TripPinImpl = (url as text) =>
let
source = Web.Contents(url, [ Headers = DefaultRequestHeaders ]),
json = Json.Document(source)
in
json;
TripPinNavTable = (url as text) as table =>
let
source = #table({"Name", "Data", "ItemKind", "ItemName", "IsLeaf"}, {
{ "Airlines", GetAirlinesTable(url), "Table", "Table", true },
{ "Airports", GetAirportsTable(url), "Table", "Table", true }
}),
navTable = Table.ToNavigationTable(source, {"Name"}, "Name", "Data", "ItemKind", "ItemName", "IsLeaf")
in
navTable;
GetAirlinesTable = (url as text) as table =>
let
source = TripPin.Feed(url & "Airlines"),
value = source[value],
toTable = Table.FromList(value, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
expand = Table.ExpandRecordColumn(toTable, "Column1", {"AirlineCode", "Name"}, {"AirlineCode", "Name"})
in
expand;
Hi @Anonymous ,
What do you want? Change your query?

No, if you have methods in connector, how do you write documentation for them?
Hi @Anonymous ,
