I have a function which takes in T::AccountId type

    Citizen get(fn candidate_name): map hasher(blake2_128_concat) T::AccountId => Option<Vec<u8>>;

e.g.

    fn add_count(origin, account:T::AccountId, phrase: Vec<u8>) {
       // I need to concatenate : account + _ + phrase, then convert it to Vec<u8> or bytes
       // Then change the Citizen storage using account
    }

Another way is:

    fn add_count(origin, account:Vec<u8>, phrase: Vec<u8>) {
       // Concatenate : account + _ + phrase, then convert it to Vec<u8> or bytes
       // Then change account to T::AccountId and then change the Citizen storage
    }

But I am unable to convert the T::AccountId type to bytes/vec<u8> or vice versa.

have you tried `account.into()` ? – Nuke Apr 12 '21 at 19:16
No, into() is not working – Amiya Behera Apr 13 '21 at 03:52
let vote_bytes: u8 = vote_account.into(); gives error => the trait `std::convert::From<::AccountId>` is not implemented for `u8 – Amiya Behera Apr 13 '21 at 03:55
with account as `AccountID`? – Nuke Apr 14 '21 at 02:49
Yes. account as AccountID – Amiya Behera Apr 14 '21 at 06:30
It's been this long this question been asked. Have you figured out an way @AmiyaBehera – Sudip Ghimire Jan 12 '22 at 09:34
@SudipGhimire No. Not sure if staurated_from can be used. https://crates.parity.io/sp_arithmetic/traits/trait.SaturatedConversion.html#method.saturated_into – Amiya Behera Jan 13 '22 at 07:47
