iCloud deleting half of my table

Other
#1

Hello,

I am trying to upload a table to iCloud. When I download it again, it is broken, I have absolutely no idea why that happens. It always cuts the table where the first “false” is. I have tried that with several options, booleans and strings, it is always the same.

theTable = {true, true, true, false, false} iCloud.set("theTable", json.encode(theTable)) --- theTableDownload = iCloud.get("theTable") theTableDownload = json.decode(theTableDownload) -- this is the remaining table: {true, true true}

Have you tried with 1 and 0 instead of true and false?

#3

Yes, and also with strings. But my original table has more than 5 values, it has 144 x true, then 4 x false and then 1 x true again. Could that be a problem?

Edit:

I have to make a new project, it could be that I am just overwriting the table so often that I am confused with what it should look like. I will write as soon as I find out something new

Your code works. If I run this code it’s correct:

local iCloud = require( "plugin.iCloud" ) local json = require("json") theTable = {true, true, true, false, false} iCloud.set("theTable", json.encode(theTable)) print ("before", json.prettify(theTable)) --- theTableDownload = iCloud.get("theTable") if (theTableDownload ~= nil) then theTableDownload = json.decode(theTableDownload) print ("after", json.prettify(theTableDownload)) end

Output:

before [true,true,true,false,false] after [true,true,true,false,false]

But in this case he’s storing the array as a JSON string, which is perfectly fine.

@inglemar, I was referring to this in particular

…Keys should be less than 64 symbols (bytes).

I would imagine a JSON string of 149 booleans would be longer that 64 bytes?

#8

True, that should be taken into consideration, but philipp3 claims that even with 5 values it was failing, which in my testing didn’t fail.

#9

No worries, I think you missed a follow up post saying "But my original table has more than 5 values, it has 144 x true, then 4 x false and then 1 x true again. Could that be a problem?"

#10

But that limitation is for keys, not values. :slight_smile:

The key is his example is “theTable”.

#11

I modified the example to generate 150 values, and the returned result from iCloud is correct.

local iCloud = require( "plugin.iCloud" ) local json = require("json") local theTable = {} for index = 1, 150 do local value = math.random( 100 ) \< 50 and true or false theTable[index] = value end iCloud.set("theTable", json.encode(theTable)) print ("before", json.prettify(theTable)) --- theTableDownload = iCloud.get("theTable") if (theTableDownload ~= nil) then theTableDownload = json.decode(theTableDownload) print ("after", json.prettify(theTableDownload)) end

Thank you very much. I think I messed up everything. Is there a way to remove the iCloud data to start all over? I don’t see the app in the iCloud settings.

Also, I think I don’t quite understand when “initialSync” in the KVSListener is called, as I never saw it happen. Is this the point where I should set the values first to avoid overwriting them if they exist?

      • EDIT

Just to confirm, iCloud was not the cause of the broken table, it was a very unlucky combination of tables overwriting each other, too long strings, bad WiFi and my inability to understand initialSync.

#13

Have you tried to use iCloud.delete() to delete the key first?

Also “initialSync” isn’t called unless there was an error writing the data. It’s a message stating that the data couldn’t be written due to the initial sync not being completed.

#14

I didn’t delete the key first, I just overwrote it, that has lead to problems with the tables, because they had a different length. I just left out the KVSListener, now it works fine. It wasn’t a bug though, just a fault on my side.
