Hello dlypka, I was investigating this, but after reading the docs I'm a bit confused:
- To use the scheduler in a module what should i do? Create a scheduler.py model and pass the scheduler created in the model to the function in my module as I do with my db? - Can I start and stop the task whenever I want? It seems that I have to insert the task in my db but I don't now when this task will be called because it depend on a certain event and maybe it never happens or it happens 500 times an hour. Thank you very much!
