Django, database retrieval not working but deleting fields and adding new fields is working
I have been able to get my 开发者_StackOverflow社区database queries to work properly for deleting existing entries and also adding new entries to the database but I am completely stumped as to why I am unable to retrieve anything from my database. I am trying a query such as:
from web1.polls.models import Poll
retquery = Poll.objects.all()
print retquery
--prints: "[ ]"
Also, if I try this, it just returns "poll object"
from web1.polls.models import Poll
retquery = Poll.objects.all()[0]
print retquery
--prints: "poll object"
I have looked at everything and there are definitely entries in the database, I have tried this with a number of different models where everything else is working otherwise so I don't know what I can do at this point, any advice is greatly appreciated
if you have provide well __unicode__
method to your model, you won't have such problem...

I finally figured this out, I am leaving this up since this can be really confusing for someone fairly new to Python, such as myself, as Django's docs don't make this entirely clear, I'm used to printing out an object and having it list everything in it but for some reason the type of object that is returned is not in such a format that doing this will work, so you need to take the resulting variable from the query and add the name of the field to the end in order to access it, such as:
If I have a field named "question" that I want to retrieve:
retquery = Poll.objects.all()
print retquery.question
This will work, whereas the way I was doing it before it just printed nothing making me think that the returned object was empty
