How can create a deferred action which is executing at specific interval

Question

#include <eosiolib/eosio.hpp>
#include <eosiolib/transaction.hpp>
#include <lib/user.h>
using namespace eosio;
using namespace user;
class hello : public eosio::contract {
  public:
      using contract::contract;

     // @abi action 
      void hi( account_name user ) {
       print( "Hello, ", name{user} );
    }
    //@abi action
     void signup(uuid_t Id, string Name,string mobileNum,uint64_t password,uint64_t gender)
    {
     tableUsrde_t user(_self, _self);
    transaction out{};
        out.actions.emplace_back(permission_level{N(tester), N(active)}, N(tester), N(hello), std::make_tuple(0xff));
        out.delay_sec = 10;
        out.send(0xff,N(tester));
            user.emplace(_self,[&](auto& record){
                record.userId = Id;
                record.userName = Name;
                record.usermobileNum =mobileNum;
                record.userpassword = password;
                record.usergender =gender;

            });
    }

};

EOSIO_ABI( hello, (hi)(signup))

and

typedef uint64_t    uuid_t;
typedef int8_t     positionType_t;
using namespace std;    
namespace  user{
    //@abi table tableuserdet i64
    struct tableUsrdet{
        uuid_t userId;
        string userName;
        string usermobileNum;
        uint64_t userpassword;
        uint64_t usergender;
        uuid_t primary_key() const {return userId;}
        EOSLIB_SERIALIZE(tableUsrdet,(userId)(userName)(usermobileNum)(userpassword)(usergender))
    };    
    typedef eosio::multi_index<N(tableuserdet),tableUsrdet > tableUsrde_t;
}

1) My requirement is a such way that signin action execute after 10 sec when I call cleos push action

2) But currently cleos push action run without delay

I dont know how deferred action work ? Is there any example or doc ? Please suggest

What's tester and tester::hello() looking like? Your code may look ok or not depending on how those are implemented. Any small error may result in the whole thing failing with no helpful error message.

Here's a full example of something that works on my machine fine:

sender.cpp

#include<eosiolib/eosio.hpp>
#include<eosiolib/transaction.hpp>
#include<string>

class sender : eosio::contract {
    public:
        sender (account_name account) : eosio::contract(account) {}

        void send(account_name account, std::string message) {

            eosio::transaction t{};
            t.actions.emplace_back(
                eosio::permission_level(account, N(active)),
                N(recipient),
                N(receive),
                std::make_tuple(message));
            t.delay_sec = 5;
            t.send(N(message), account);
        }
};

EOSIO_ABI(sender, (send))

recipient.cpp

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

class recipient : eosio::contract {
    public:
        recipient(account_name account) : eosio::contract(account) {}

        void receive(std::string message) {
            eosio::print(message);
        }
};

EOSIO_ABI(recipient, (receive))

cleos

$ cleos wallet unlock
$ cleos wallet keys
[
    "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV"
]
$ cleos account create eosio sender EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
$ cleos account create eosio recipient EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
$ cleos account create eosio controller EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
$ cleos set contract sender contracts/sender
$ cleos set contract recipient contracts/recipient
$ cleos set account permission controller active '{"threshold": 1,"keys": [{"key": "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV","weight": 1}],"accounts": [{"permission":{"actor":"sender","permission":"eosio.code"},"weight":1}]}' owner -p controller
$ cleos push action sender send '["controller", "my_message"]' -p controller

The message should show up in nodeos output assuming it's configured with contracts-console=true
