I have a collection where one field is "ip" and I want to put all the IP values in a list like this:
["1.1.1.1", "2.2.2.2", "3.3.3.3"]
Here's what I've got so far:
result = db.ips.find({}, {"ip": 1, "_id":0}) # Cursor object
ip_list = list(result) #list
print ip_list
The ip_list is a list, but it looks JSON-y and contains not only the IPs, but also the field name:
[{u'ip': u'1.1.1.1'}, {u'ip': u'2.2.2.2'}, {u'ip': u'3.3.3.3'}]
How can I get the format with only the IP strings? I could loop over the whole list, of course, but I'm hoping there's a better way to go about it.
You should be able to use distinct :
print db.ips.distinct("ip")
Or if you need to filter first:
print db.ips.find(<foo>).distinct("ip")
