Re: Using Model Object Data in views.py

[rpupkin77]

Yes, I actually had an error elsewhere apologies.

I understand objects fine, BTW but am new to Django (beyond the
tutorials).

It was odd to me that the error was happening it seemed like i should
have had access to the data.All set now.

You don't just get the unicode, you get the whole object. If you just
type 'vid' into the console, of course you'll just see the unicode
representation (actually it's the value of __repr__, which in turn
calls __unicode__) but the whole object is there. You access other
attributes like you would any other object - vid.id, vid.field1, etc.

It sounds like you don't really understand objects in Python, or maybe
objects at all. I recommend you read a basic beginner's guide to
programming in Python - there's a list here:
http://wiki.python.org/moin/BeginnersGuide/NonProgrammers
I haven't read any of them (I learned from Dive Into Python, which is
aimed at people who already know programming from other languages) but
I've heard "How to think like a computer scientist" is good.

this happens when you coerce (or 'cast') the model object into a
string-like value.  maybe when 'examining' it.

if you simply try to access its fields, you should find them there.

Using Model Object Data in views.py

[rpupkin77]

Hi,

this is probably a  really basic question, but i can't find the answer
anywhere.

I need to get data from a model and use it in the view (views.py),
before I pass it to the template. However, the result I get back (when
i examine the local vars) has only the value returned by the __unicode
function, in this instance, the "title" column.

I need the title to continue to be what is returned by unicode but i
need access to a different field in that model  and pass it to a third
party api.

essentially my code would looks like this:

from models import Video

def get_video_ids:
 vids = Video.objects.all()

 for vids in vid
  do stuff

the vids variable contains a list like this: [Video: vid title one,
Video: vid title two]

I essentially need the id.

I have tried different ways of extracting, but they fail.

Thanks.
