lesson-14 General questions!

Hey! These are are Snippet from Patrick's video.
Just wondering why Patrick would take tokenUris instead of dogTokenUris?(yellow)
and he would not use networkConfig[chainId] in subscriptionId when using in args.(Green)
Anyone know answers to this?

@TimeKeyRoll : You will understand it, In the video after few minutes!

If you are strictly following along the course, Just keep following, It will clear you query by it self!

[TimeKeyRoll]

ok thanks

He does, later on. Your query is justified though; you are learning! :) (regarding args)

Just wondering why Patrick would take tokenUris instead of dogTokenUris?(yellow)

I do not quite understand this one. Could you elaborate?

[TimeKeyRoll]

In Contract constructor args is dogTokenUris but he's using tokenUris in deploy scripts?
For refrence you can also check the both screenshots which comes with the post.

[krakxn]

Again, it is just the name and only used for reference; it can be named anything and does not have to equal the one in the contract. It is just for reference (for debugging) that we name variables conveniently.

The only thing important, and necessary, is that tokenUris is an array of strings (refer constructor's dogTokenUri 's data-type) with its size (i.e. length) <= (i.e. less than or equal to) 3.

Whilst, currently in your lesson, it is not defined. Later on, when he does define tokenUris it contains this value:

let tokenUris = [
    "ipfs://QmaVkBn2tKmjbhphU7eyztbvSQU5EXDdqRyXZtRhSGgJGo",
    "ipfs://QmYQC5aGZu2PTH8XzbJrbDnvhj3gVs7ya33H9mqUNvST3d",
    "ipfs://QmZYmH5iDbD6v3U2ixoVAjioSzvWJszDzYdbeCLquGSpVm",
]

and if Pinata,

if (process.env.UPLOAD_TO_PINATA == "true") {
        tokenUris = await handleTokenUris()
    }

which is passed down appropriately as tokenUris for the deployment.

I know what you are saying.
Or
If i Modify my question : does not we require to have same name in deploy script whichever we have in contract's constructor?

[krakxn]

does not we require to have same name in deploy script whichever we have in contract's constructor?

No, it does not have to be the same name. The name does not matter at all in the logic of the code, only for our own reference.

What matters in the logic is given above (quoting below):

The only thing important, and necessary, is that tokenUris is an array of strings (refer constructor's dogTokenUri 's data-type) with its size (i.e. length) <= (i.e. less than or equal to) 3.
