Error ; Member "push" is not available in address[] memory outside of storage

Question

I am writing a function to generate trail of all address who owned an asset ( assets is a mapping of asset no to owner no to address of owner). However while making array of address 'listofOwners' I get compilation error, Member "push" is not available in address[] memory outside of storage.

function viewTrail(uint256 _assetNo) public view returns(address[] memory){
   address[] memory listofOwners = new address[](assets[_assetNo].ownerNo);
  for(ownerNo = 1; ownerNo<= assets[_assetNo].ownerNo; ownerNo ++)
  {
  listofOwners.push(owneraddr[_assetNo][ownerNo]);
  }
return listofOwners;}

Can you please suggest a solution or some other code to generate trail of owners of an asset?

Answer 1

You can assign the elements to the array position by referencing the element key like myArray[0] = ‘new value’;

The following example uses a view function, because the array is in memory:

function getMultipleAddresses( string[] calldata ids) public view returns (address[] memory) {
address[] memory _addresses = new address[](ids.length);

for (uint256 i = 0; i < ids.length; i++) {
  string memory id = ids[i];
  require(_idToAddress[id] != address(0), 'Missing address');
  address payable _address = payable(_addresses[i]);

  _addresses[i] = _address;
}
return  _addresses;

}
