Laravel scheduler cron options from database - laravel

Question

I am new to laravel.
I am finding how can i execute schedules.
The schedule parameters (frequency, command) are stored in a mysql table.
I have thought a solution which is:
Use file_put_contents to write in app/Console/Kernel.
Any better idea would be welcome.
Thanks in advance,

Answer 1

The frequency of a certain command is defined on multiple levels. The Cron entry on your server calls the schedular every minute. In your scheduler there are frequency options as well.
One of the possibilities to let paramaters that are stored in the database define the frequency of command executions is to add a executed_at field to the table and a local scope to your Commands model that validates the schedule parameters in your mysql table:
public function scopeReadyToExecute($query)
{
return $query->where('executed_at', '<=', Carbon::now()->subMinutes(5)->toDateTimeString());
}
In this example the frequency is 5 minutes, of course you have to change this value according the the value in the frequency field.
Now, you could for example define master:command in Kernel.php to be executed every minute:
$schedule->command('master:command')->everyMinute()
In the handle of master:command you call the scope function to get the commands that are ready to execute:
public function handle()
{
$commands = Command::readyToExecute()->get();
foreach ($commands as $command) {
$this->call($command->name)
}
}
Each command that is ready to execute according to the parameters defined in your table will be executed.
Good luck!

Here in my solution.
app/Console/Kernel.php
$report_schedules = ReportSchedule::all();
foreach ($report_schedules as $report_schedule) {
$method_name = (string)$report_schedule->report->method_name;
$schedule->call(function () use ($method_name, $report_schedule) {
$emailSchedules = new EmailSchedules();
$email_List=array_unique(array_merge($report_schedule->users()->get()->lists("email")->toArray(), $report_schedule->groups()->with(["users"=>function ($query){$query->select("email");}])->get()->toArray()));
$users=\App\User::whereIn("email",$email_List)->get(["first_name","last_name","email"]);
$users_to=[];
$emails_to=[];
foreach($users as $user){
array_push($users_to,$user->first_name." ".$user->last_name);
array_push($emails_to,$user->email);
}
$emailSchedules->$method_name($emails_to,$users_to);
})->cron($report_schedule->frequency)->name('mail')->timezone("Europe/Athens");
}
Hope that help someone in the future.
