Lesson 7: Using Mocks

[kailashchoudhary11]

How do I get the sub_id after deploying VRFCordinatorMock?

Hi @kailashchoudhary11

You can do below to get sub_id:

# Creating Subscription And Getting SubscriptionId...
create_sub_tx = vrfCoordinatorV2Mock.createSubscription()
create_sub_tx.wait(1)
subId = create_sub_tx.return_value
# Second way to get subscription id
subID = create_sub_tx.events["SubscriptionCreated"]["subId"]
print(f'SubscriptionId: {subId, subID}')

Just note that sub_id is used in VRF_V2 not in previous 1st version. You can also take a look at my whole lottery on VRF_V2 here: https://github.com/Neftyr/Lottery-On-VRFConsumerBaseV2-Python

@cromewar @Neftyr Did you'll find anything wrong in the code?

[cromewar]

Not particularly, I'll clone your repo and try to reproduce the error.

@kailashchoudhary11

Sorry I was out for 1 week vacation have you guys solved issue and figured out what was wrong?

[kailashchoudhary11]

@Neftyr yeah the issue is resolved. There was some problem with the brownie environment.
