The given contract doesn't exist in the blockchain

Question

I have got contract code below:

#include <eosiolib/eosio.hpp>
#include <eosiolib/print.hpp>

using namespace std;
using namespace eosio;

class deneme: contract {
   // @abi table  
   struct countries {
      name sender;
      string country;

      name primary_key() const { return sender; }
      EOSLIB_SERIALIZE( countries, (sender)(country) )
   };
public:
   deneme(account_name self):
    contract(self),
    _countries(_self, _self) {}

   multi_index< N(countries), countries > _countries;

  // @abi action
  void myaction(name sender,string country) {
    // add to table, first argument is account to bill for storage
     _countries.emplace(sender, [&](auto& row) {
        row.sender = sender;
        row.country = country;
     });
  }
};
EOSIO_ABI( deneme, (myaction) )

And generate wast and abi file with:

eosiocpp -o deneme.wast deneme.cpp
eosiocpp -g deneme.abi deneme.cpp

Deploy contract with (there was no change on nodeos terminal when setting contract):

cleos set contract eosio ../deneme -p eosio

Finally I try to push action like :

cleos push action deneme myaction '{"sender":"eosio","country":"anywhere"}' -p eosio

I've got an error below :

Error 3060004: Contract Query Exception
Most likely, the given contract doesnt' exist in the blockchain.

nodeos says:

Also when I set contract nodeos says nothing (no changes on nodeos terminal). Where am I doing wrong?

Answer 1

You need to set the contract to your deneme account not to eosio.

For local development you have to do the following (considering you already have a wallet and unlocked it).

Create two key pairs for active and owner

cleos create key

Output:

Private key: <private_key_1>

Public key: EOS....xyz

run it twice and write down the key pairs

Now import them to your wallet

cleos wallet import <private_key_1> -n <wallet_name> 

Import the eosio private key for account creation:

cleos wallet import 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3 -n <wallet_name> 

Then you need to create your account deneme

cleos create account eosio deneme <owner_public_key> <active_public_key> 

Deploy to deneme account

cleos set contract deneme <path_to_contract> <path_to_contract>/deneme.wast <path_to_contract>/deneme.abi -p deneme

Test an action

cleos push action deneme myaction '{"sender":"eosio","country":"anywhere"}' -p denem@active

Answer 2

cleos set contract eosio, should not be eosio, but deneme, and you must create an account for deneme
