How to change the Databin file name?

Question

You can create a Databin file like this:

This link can check you file.I found I couldn't change it's name after I create it.As the documemtation of RenameFile in Details and Options:

RenameFile works on cloud objects, changing their cloud file names but not their UUIDs.

So I guess it can do this.But how to do it?

Answer 1

The name of a Databin

bin = CreateDatabin["Name" -> "FirstName"];

bin["Name"]
(* "FirstName" *)

can be changed with SetOptions:

SetOptions[bin, "Name" -> "LastName"];

The modification does not seem to be reflected when evaluating again the above:

bin["Name"]
(* "FirstName" *)

and the summary box also still displays the old name:

bin

It can be checked however that the change is indeed performed by going on the datadrop website:

• before the evaluation of SetOptions:

• after its evaluation and reloading the page:

Note that if we exit the kernel,

LocalSymbol["BinUUID"] = bin["UUID"];
Exit

and load the bin in a new session, we recover the new name:

bin = Databin[LocalSymbol["BinUUID"]]

Remove[LocalSymbol["BinUUID"]];

bin["Name"]
(* "LastName" *)

Update

Alternatively, all the cache related to the bin can be clear:

SetOptions[bin, "Name" -> "MiddleName"];

bin["Name"]
(* LastName *)

DownValues[DataDropClient`Private`datadropclientcache] = 
   With[{sid = bin["ShortID"], uuid = bin["UUID"]}, 
      DeleteCases[
        DownValues[DataDropClient`Private`datadropclientcache], 
        patt : HoldPattern[lhs_ :> rhs_] /; MemberQ[patt, sid | uuid , Infinity]
      ]
   ];

bin["Name"]
(* MiddleName *)

or the relevant part can be updated appropriately:

SetOptions[bin, "Name" -> "NoName"];

DataDropClient`Private`datadropclientcache[{"DatabinIDs", bin["UUID"]}] = 
     Options[bin][[1, 2]]

bin["Name"]
(* "NoName" *)
