It can be executed in a Web2Py shell, it can be in a controller that responds to an input, etc. Ooops, I just re-read what you have there ... don't insert directly into the table, call *queue_task()* where ever you need to schedule a task. (Note, there are a LOT of fields in the database table, this post will give you some idea: <URL:https://groups.google.com/d/msg/web2py/V4FftTa0CfE/Yas8cNWUEAAJ> ) I have my *queue_task()* in the model, but it is only executed when I don't already have a task queued. Since model files get loaded on each request, you don't want to be too careless about queuing a task there. Luckily, there is *task_status()*. > > Also, is there a way to let a scheduler run at a time writen in a db once > and then rest until the next time occurs? or is a permanent run every few > seconds checking for certain criteria the better solution? > Check out the other parameters of the queue_task() call (follow the book URL). There's a starttime as well as a period.

There is a request environment, but some fields that only apply to http requests aren't used, and some scheduler-specific fields are used. My code is mostly in a module file, so I have to use an instance of *current* to pass relevant information.
