python - How to add a task to a group in Celery? -


i want incrementally build group of celery tasks in code because creating tasks based on logic in loop.

for example:

my_group = group() item in items:     if item.is_special():         # doesn't work...         my_group.add(special_processing.s(item.id))     else:         my_group.add(regular_processing.s(item.id))   res = my_group()

i've read groups partials, good, how combine partials form group?

a simple way i've found far create list of tasks, , convert group.

so:

tasks = [] item in items:     if item.is_special():         tasks.append(special_processing.s(item.id))     else:         tasks.append(regular_processing.s(item.id)) res = group(*tasks)

i haven't tested yet, i'll update answer if doesn't work.
