Договор о солидности не связан с django html

/ 15 марта 2019

моя программа солидности работает хорошо .. я просто установил для среды web3 Обеспечение. Затем я скопировал abi и адрес в index.html .i также установил учетную запись по умолчанию как web3.eth.defaultAccount = web3.eth.accounts [0];но соединение не работает, он сказал, что учетная запись не определена, это моя программа солидности 

pragma solidity ^0.4.11;

контракт HDataAccessManager {

mapping (string => string) dataLink;
mapping (string => string) dataHash;
mapping (string => bytes32) private passwords; 
string[] users;


function _isValid(string _user_id, string _encryption_key_hash) returns (bool) {
    for(uint i = 0;i<users.length;i++){
        if(keccak256(users[i]) == keccak256(_user_id) && 
            keccak256(_encryption_key_hash) == passwords[_user_id]) {

            return true;
        }
    }
    return false;
}

function addUser(string _user_id, string _encryption_key_hash) {
    users.push(_user_id);
    passwords[_user_id] = keccak256(_encryption_key_hash);
}

function totalUsers() returns (uint) {
    return users.length;
}


// link is alias of generated_id
function storeLink(string _user_id, string _link){

    // check if user is present in blockchain
    //require(_isValid(_user_id, _encryption_key_hash));

    dataLink[_user_id] = _link;
}

function storeHash(string _user_id, string _hash){

    // check if user is present in blockchain
    //require(_isValid(_user_id, _encryption_key_hash));

    dataHash[_user_id] = _hash;
}


function retrieveLink(string _user_id, string _encryption_key_hash) returns (string, string) {

    //check if user is present in blockchain
    require(_isValid(_user_id, _encryption_key_hash));

    string link = dataLink[_user_id];
    string hash = dataHash[_user_id];
    return (link, hash);

}
