How to call the nft mint by the contract?

I want to call the mint function:

#[payable]
    pub fn buy_nft(&mut self, token_id: String) {
             self.tokens.mint(
                  token_id,
                  new_owner_id,
                  Some(token_metadata),
        )
}

But the predecessor needs to by owner_id, my owner_id is the contract id on which contract is deployed.

assert_eq!(env::predecessor_account_id(), self.owner_id, "Unauthorized");

When I call this function by say charlie, it gives Uauthorized error:

call!(
    charlie,
    contract.buy_nft("123".to_owned()),
    deposit = to_yocto("10")
).assert_success();

Error:

Smart contract panicked: panicked at 'assertion failed: `(left == right)`
      left: `"charlie"`,
     right: `"contractname"`: Unauthorized'

How can I call self.token_mint by the contract, through charlie?

Solution

  • Currently the answer is to copy the mint function from the standard implementation and customize as you see fit.

    The better interface will be coming in the future updates.
