Schedule tasks

Rails
1

Hi,

I need some help to schedule some tasks.
I have a database table with a column called: start

I need to send an email and update a column at that start date.
How can I iterate my database table, verify if today has some tasks to
be
executed and send an email.

Thanks.

You have described a problem with a large number of aspects. Which
particular bit do you not know how to do? Running a background job?
Iterating the table? Testing whether you have to do something?
Sending the email? Updating the database? Anything else?

Sorry Colin,

Actually I need help about how can I run a background job.
This job needs to listen all events registered in database and send an
email when the dates match.

I’m found clockwork gem as an option to do this.
I have to create a worker that runs every minute and verifies if current
date/time is the same from the event in the database.
Is it a good alternative ?

Thanks.

Well you can tell us that. If it working well and was easy to
implement then yes.
I don’t know how you have coded it but a suggestion is to put all the
logic in a method of one (or more) of the models and then just call
that from the worker. That way the code is easier to test using your
automated tests.

I would probably just have written a rake task and called it from
cron, but I have not tried the clockwork gem so maybe it is a good
alternative. Does it play well with rails? I notice that it has not
been updated for a year or so, but maybe that is not an issue.
