Hi!

I made an html page and if I refresh it, a new email sent to my chosen users. It works fine if I manually reach this page. If I add a new task to PA to refresh this page daily nothing happens. I can't find anything in the server or error log, nothing appears about this task. The url to this page: mysite/performance/emails I added this url to the tasks: /home/myusername/folder/performance/emails

This is the first time I try to use the task scheduler. Am I doing something wrong?

Scheduled tasks have their own logs -- the link is the first button in the "Actions" column on the task table. Is anything showing up in there?

Yes, I found the log, thank you. The path that I added is fine, it ran the file I made but it say: Permission denied.

Looking at your tasks' configuration, it looks like you've scheduled a .html file, which is not something I'd expect. A scheduled task will just run the file, just as if you'd typed the path into a Bash console, so HTML won't run there.

What you need to do is write a script which, if it's run from a Bash console, will achieve what you want to do. If you want (say) a particular view on your website to be accessed periodically, you could do that by using curl to hit the appropriate URL. But a more elegant solution would be to write a Python script to actually run the code directly without accessing your site. If you're using Django, then I would recommend that you read up on custom Django management commands, as they're the most elegant way to achieve that.

Thank you but I think my experience is under that I could write a management command. Curl looks easier to me.

I tried the same code as a py file without the html part. If I try to run it as a task I get this:

ImportError: attempted relative import with no known parent package

If I can't run this script as a task which cases could the task function be helpful?

Management commands make everything much easier.

What do you try to import there?

This is the whole code I try to use:

This is the error I get:

Traceback (most recent call last): File "/.../performance/emails.py", line 9, in <module> from .models import Profile, Projekt_megtartas ImportError: attempted relative import with no known parent package

The reference to the model is fine, it works well in other files in the same app.

Since it's a relative import, the import may work in one file and not in another depending on the location in the class hierarchy. The Python PEP 8 suggests that absolute imports should be used unless you have a good reason to use a relative import instead.

OK, thank you :)
