My contract is as follows:

pragma solidity ^0.4.21;
contract try {
    mapping (address=>bytes32[10]) Map;

    function try(){}

    function fill_map(bytes32[10] _attributes) public  {

    function get_map(address id) view public returns (bytes32[10]){
      return Map[id];


The error I get is:

Member “push” not found or not visible after argument-dependent lookup in bytes32[10] storage reference Map[msg.sender].push(_attributes)

I also tried inserting the data with a loop as follows:

    for(uint i=0;i<10;i++)

Also results in the same error.


You have to assign the data directly

function fill_map(bytes32[10] _attributes) public  {
        Map[msg.sender] = _attributes;

Also try is a reserved keyword and the compilation will fail. You have to use another name for your contract.


The syntax to insert data in a mapping (key => value) Map is

Map[key] = value 

In your case it is Map[msg.sender] = _attributes

push() function inserts data into array but not into map.
