lesson 14 random question about tags

[TimeKeyRoll]

Hi In NFT Chapter we have 3 contracts and every contract has different tags like :
["all", "BasicNft", "main"]
["all", "RandomIpfsNft", "main"]
["all", "dynamicsvg", "main"]

When we run : `npx hardhat deploy --tags "mocks,RandomIpfsNft"

`npx hardhat deploy --tags "mocks,dynamicsvg".

Contracts gets deployed individually.

Now Question is if i want to deploy all contracts all together then i run : npx hardhat deploy --tags "mocks,main" and it gives me an Error.
So how i deploy all the contracts in one go?
And what is difference between all and main and when do we use all ?

If anyone can help me to understand it I would highly appreciate that.

@TimeKeyRoll :

If you wanna deploy all of your contracts at once, Just run : npx hardhat deploy

The main tag we made for our test net deployment,

In the video ahead, we will gonna make another deploy script called 04-mint.js In that we will mint all the NFTs from all three contracts at once, And in that script we will not going to have the main tag!

So, with the main tag we can only deploy all our contracts on the testnet, without interfering our 04-mint.js deploy script.

And we will gonna run our mint script individually by mint tag.

all tag is an option to use in your testing! And its upto you to use the all tag in your testing or just use the specific contracts name instead!

So, That's the difference between all and main

@TimeKeyRoll :

You can just skip the all tag, It will be totally fine! Since you are using specific contracts name anyways,
by defining the contracts name to target like : "dynamicsvg","mocks" like this.

For me personally, I use all tags in my testing! So, they are helpful for me!

@abossofmyself I'm sorry if i failed to ask in a right way. My question is if we can deploy contracts individually or altogether and also have main for test net. then why it is all mentioned there? what is the purpose of it? And how it is different from main ? and when we do we use it?
P.S My contracts has been deployed and i get that other than all . just curious about this.

@TimeKeyRoll :

In our deploy scripts every script has an all tag, So, If we deploy our contracts on a test net It will trigger our mint script as well, By this command : npx hardhat deploy --tags "all" --network goerli

We don't want that, Specifically in this lesson : So we gave all three contracts a unique tag i.e main So, that only our contracts can deploy.

The all tag is just for deploying on our hardhat node, like npx hardhat deploy --tags "all" --network localhost

@abossofmyself perfect!

I remember @othaime-en told me we can also use custom .. do you know something about this as well ?
If you could share your view my all confusion about tags would be gone :)

[RoboCrypter]

@TimeKeyRoll : Yes! custom tag is like our main tag, And you can name it any thing you want, like you can change it to : testnet tag, custom tag etc

tags are a tool for us, for which contracts we wanna deploy as per our choosing!

hey @abossofmyself can you please help me with this

here is my randomIpfsNft.test.js

const {developmentChains, networkConfig} = require("../../helper-hardhat-config")
const {getNamedAccounts, deployments, ethers} = require("hardhat")
const {assert, expect} = require("chai")

!developmentChains.includes(network.name)?describe.skip:describe("randomIpfs NFT test", function(){
let randomIpfsNft, deployer, vrfCoordinatorV2Mock
const chainId = network.config.chainId

beforeEach(async function(){
accounts = await ethers.getSigners()
deployer = accounts[0]
await deployments.fixture(["mocks", "randomIpfs"])
randomIpfsNft = await ethers.getContract("RandomIpfsNft")
vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
})
describe("constructor",() =>{
it("sets the initial value correctly", async function(){
const dogTokenUriZero = await randomIpfsNft.getDogTokenUri(0)
const isInitialized = await randomIpfsNft.getInitialized()
assert(dogTokenUriZero.includes("ipfs://"))
assert.equal(isInitialized, true)
})
})
describe("requestNft",()=> {
it("fails if payment is not enough", async () =>{
await expect(randomIpfsNft.requestNft()).to.be.revertedWith("RandomIpfsNft__NeedMoreEth")
})
it("should revert an error if payment amount is less than mint fee", async () =>{
const fee = await randomIpfsNft.getMintFee()
await expect(randomIpfsNft.requestNft({
value:fee.sub(ethers.utils.parseEther("0.001")),}).to.be.revertedWith("RandomIpfsNft__NeedMoreEth"))
})
it("emits an nftRequested events",async () =>{
const fee = await randomIpfsNft.getMintFee()
await expect(randomIpfsNft.requestNft({value:fee.toString()})).to.emit(randomIpfsNft,"NftRequested")
})
})
describe("fulfillRandomWords", async () =>{
})

describe("getBreedFromModdedRng", async () =>{
it("should return pug if the moddedRng is less than 10", async () =>{
const expectedValue = await randomIpfsNft.getBreedFromModdedRng(7)
assert.equal(0, expectedValue)
})
it("should return shiba-INU if the moddedRng value is more than 10 but less than 40", async () =>{
const expectedValue = await randomIpfsNft. getBreedFromModdedRng(21)
assert.equal(1, expectedValue)
})
it("should return st.bernard if moddedRng value is more than 40 but less than 100", async () =>{
const expectedValue = await randomIpfsNft.getBreedFromModdedRng(77)
assert.equal(2, expectedValue)
})
it("should revert back an error if moddedRng value exceed 100", async () =>{
await expect(randomIpfsNft.getBreedFromModdedRng(100)).to.be.revertedWith("RandomIpfsNft__RangeOutOfBounds")
})
})

})

firstly, i do not know where i am going wrong but half of these tests are not working
secondly, i cannot figure out how to write "fulfillRandomWords" tests and i am unable to understand patrick's solution
thirdly, why are we putting these numbers (7,21,77)
const expectedValue = await randomIpfsNft.getBreedFromModdedRng(7)
const expectedValue = await randomIpfsNft. getBreedFromModdedRng(21)
const expectedValue = await randomIpfsNft. getBreedFromModdedRng(77)
how are we getting these??? can you please explain

[TimeKeyRoll]

1)-You have to mention Errors right here so one could figure what could be possibly wrong.

2)-fulfillRandomWords comes from VRFConsumerBaseV2.sol and VRFCoordinatorV2Interface.sol has the function named requesrRandomWords in this case we have named it requestNft function. AND we could name this function anything we want.
So its job is to get us the randomNumber and do the task whatever we've mentioned and look for fulfillRandomWords to check if everything we have mentioned is true and gets it executed.

3)-Remember each dog has different rarity`. and it comes with a function which is

 function getChanceArray() public view returns (uint256[3] memory) {
        return [10, 30, MAX_CHANCE_VALUE];
    }

As you have mentioned (7,21,77) See 7 is less than 10 and 21 is also smaller to 30 and 77 is smaller to its MAX_Value. it could be any number tho. lets say it is (5,16,89). it will still work the same way.

@DANIA001 This is what i know so far. just see if these things helps you to get the explanation.
