Attempting to insert into reference table

[RobertCorbet]

I am attempting to write a function that runs once to compile a large collection of modules into a single reference table. The reason I need to do this is to get another piece of code to operate efficiently without looping through every single time.

I am able to get values from the looped modules, but whenever I try to insert them into my reference table, they refuse to go. I created a pcall to see if there’s some kind of formatting issue, and the pcall just errors out with table index is nil.

Build Function

mod.RegModuleReference = {}

mod.BuildModuleReference = function()
	
	for i,module in pairs(cm.reg:GetChildren()) do
		
		if module:IsA("ModuleScript") then
			local thisModule = require(module)
			print(module.Name.." "..thisModule["groupId"])
			print("\n")
			print("MODULE REFERENCE: Located module: "..module.Name)
			
			local success, errorReason = pcall(function()
				table.insert(
					mod.RegModuleReference,1,
					{
						[thisModule["groupId"]] = {
							1
						}
					}
				)
			end)
			
			if not success then
				error(errorReason)
			end
			
			print("MODULE REFERENCE: Inserted values from: "..module.Name)
			
			local testIndex = table.find(mod.RegModuleReference,"purplepeopleeater")
			print(testIndex)
			print(mod.RegModuleReference)
		end
		
	end
	
end

Edit 1: Error was resolved, but inserting into the reference table is still broken.

testIndex probably doesn’t work because you are inserting a table that contains a dictionary into the table:

table.insert(
		mod.RegModuleReference, 1,
		{
			[thisModule["groupId"]] = {
				1
			}
		}
	)

Try looping through it and printing all of the values and the keys like this:

for key,value in pairs(mod.RegModuleReference) do
   print(key,value)
end

This is correct somewhat. Inserting regular strings into the table also doesn’t work, so I don’t think it’s because of a dictionary.

Is "groupId" part of every module you’re requiring?

[CodeDel (Code)]

try this:

mod.RegModuleReference[1] = {
   [thisModule["groupId"]] = {1}
}

[DataSigh]

That doesn’t do the same thing

[CodeDel (Code)]

so the [thisModule["groupId"]] is probably not returning the string

[DataSigh]

Yup, he probably doesn’t have "groupId" as part of every module script and it’s trying to index nil because it doesn’t exist

[RobertCorbet]

I do. The error has been fixed, but I still can’t insert anything into the table, even minor strings.

[DataSigh]

Is the code above still the one you’re using to insert items into the table? And the error is under the pcall?

[RobertCorbet]

Solution found. I typed out my table.insert incorrectly. Too many brackets.
