Trouble retrieving historical transactions in React

Moralis General
#1

Hello! Im trying to get historical BSC transactions after logging in through MM and getting an empty array back.
I successfully log in and get my user name from Moralis
I also see all my BSC transactions in the Moralis dashboard…any ideas what Im doing wrong here?

  const { authenticate, isAuthenticated, user, Moralis, logout, isInitialized } = useMoralis();
  console.log(isInitialized);   // returns true

  const displayUserName = () => {
    if (!isAuthenticated) return '';
    console.log(Moralis.User.transactions);    // returns undefined
    console.log(Moralis.User.current);

    return user.get('username');
  };

  const getUserTransactions = async (user: any) => {
    // create query
    const query = new Moralis.Query('BscTransactions');
    query.equalTo('from_address', user.get('bscAddress'));

    // run query
    const results = await query.find();
    console.log('user transactions:', results);  // returning []
  };

  const getStats = () => {
    const user = Moralis.User.current();
    if (user) {
      getUserTransactions(user).then((resp) => console.log(resp));  // undefined
    }
  };

Hey @ACBassman

Take a look at Quick start User object Article

You should set a global constant:

const user = Moralis.User.current();

For getting info like: ethAddress, username … You should use attributes

const user = Moralis.User.current();

const userAddress = user.get("ethAddress");
const username = user.attributes.username;

Hope this helps you :wink:

@Yomoo Thank you for the quick response!!
Is the user you are setting for the global different from the user pulled from the useMoralis() method below?

#4

gettransactions

No, this is the same. And it is better to use user from useMoralis()

#6

But before using user from useMoralis() in your code
Always do a check if(isAuthenticated)

Ahh gotcha, thank you for the quick response. I am doing this check at login and rendering username to ensure authentication.
I’m still a little confused because this is from the quickstart tutorial

    // create query
    const query = new Moralis.Query('BscTransactions');
    query.equalTo('from_address', user.get('bscAddress'));

    // run query
    const results = await query.find();
    console.log('user transactions:', results);  // returning []
  };

  const getStats = () => {
    const user = Moralis.User.current();
    if (user) {
      getUserTransactions(user).then((resp) => console.log(resp));  // undefined
    }
  };```

I recommend you watch the video I CLONED ZERION IN 20 MINUTES. From there you can get a lot of useful stuff for Moralis development on React . :wink:

It’s okay, you should use ethAddress because it used for transactions on all chains

query.equalTo('from_address', user.get('ethAddress'));

Ahhh good to know - that did it!! More documentation around the different get types would be really helpful :nerd_face:
Also, this projects that the video references ( https://github.com/MoralisWeb3/react-moralis#usemoraliscloudfunction ) is not the react boilerplate available here - https://docs.moralis.io/getting-started/demos and would be super helpful!

This is true, not all demos from the github are included in the documentation :face_with_monocle:
The Moralis documentation is constantly being updated and expanded.

Happy BUIDLing :wink:
