bulk_create example code provided seems to go into infinite loop

[blokeish]

The code provide here seems to go into an infinite loop. The batch list variable seems to always get the first 100 items from objs list, so the batch list will never go empty.

from itertools import islice

batch_size = 100
objs = (Entry(headline="Test %s" % i) for i in range(1000))
while True:
    batch = list(islice(objs, batch_size)) # <--- this always seems to be yielding the same single first batch.
    if not batch:
        break
    Entry.objects.bulk_create(batch, batch_size) 

I have seen this had got carried over to stack over flow. I am relatively new to Python and Django, so, sorry if I am making a stupid entry.

from itertools import islice
from myapp.models import Entry 

batch_size = 100

while True:
    objs = (Entry(headline="Test %s" % i) for i in range(1000))

    batch = list(islice(objs, batch_size))
    if not batch:
        break
    Entry.objects.bulk_create(batch, batch_size)

try this

Make sure that the objs = (Entry(headline="Test %s" % i) for i in range(1000)) line is making a tuple rather than a list. If using a list it won't progress the iterator and will loop infinitely
