I think the confusion here is over the word 'meta'.
Once upon a time, you defined models by starting out with:
from django.core import meta
But *within* the model itself, you specified extra options by adding
an inner class called 'META', like so:
from django.core import meta
class MyModel(meta.Model):
name = meta.CharField(maxlength=250)
blurb = meta.TextField()
class META:
unique_together = (('name', 'blurb'),)
'META', here, has nothing whatsoever to do with the class 'django.core.meta'.
Now, you do this:
from django.db import models
class MyModel(models.Model):
name = models.CharField(maxlength=250)
blurb = models.TextField()
Class Meta:
unique_together = (('name', 'blurb'),)
In other words, inside the model you define a class called 'Meta'.
This isn't an imported class, and there is no 'meta' class anywhere in
Django that you need to pull in -- it's a class that *you* create,
*inside* your model class.

Re: django/core/meta
Cheers Chris,
Finally saw that but I have tried it and have the following problem...
The code:
distribution_list = models.ForeignKey(DistributionList)
subscriber = models.CharField(maxlength=30)
unique_together=((distribution_list, subscriber),)
gives the following sql
"id" serial NOT NULL PRIMARY KEY,
"distribution_list_id" integer NOT NULL REFERENCES
"textnotifier_distributionlist" ("id"),
"subscriber" varchar(30) NOT NULL
the unique fields are not created.
the same happens for unique_together=(("distribution_list",
"subscriber"),)
Is there something I need to do or am leaving out?
Thanks again
Brian

Take a look at the model documentation[1]; most of the names of the 'meta' and 'admin' options on models haven't changed, they've just moved -- now when you're defining a model you start with 'from django.db import models' instead of 'from django.core import meta'.

What I was trying to say -- sorry if it wasn't clear -- is that in Django trunk django.core.meta no longer exists; it's been replaced (as explained in those pages I linked to). If you want to stick with an older version of Django, check out the sidebar at http://www.djangoproject.com/download/ to download a previous release.

Hey Brian, A "svn update" won't do you any good, because that gets you the *latest* version of Django, which no longer uses django.core.meta. What you want to do is one of these two things: * Get version 0.91 from http://www.djangoproject.com/download/ . * Get the latest "0.91-bugfixes" release from http://code.djangoproject.com/svn/django/branches/0.91-bugfixes/ . This is a branch devoted to maintaining the 0.91 version of code (which is what you're using), purely to fix big bugs.

Re: django/core/meta
Also...
I have downloaded the .tar.gz file from the django site and browsed to
django/core and again there is no mention of meta.
Is there something I'm missing?
If there is no work around this for me, is there any other way I can
implement the following code...
distribution_list = meta.ForeignKey(DistributionList)
subscriber = meta.CharField(maxlength=30)
class META:
unique_together=(("distribution_list", "subscriber"),)
?
It is the unique_together that I need to implement.
Thanks in advance
Brian

Re: django/core/meta
Thanks Jacob, However with the project I'm working on, I can't change the Django version I'm working on. I have tried doing an SVN update on the core directory but meta was not included in it. Is there anyway I can download the relevant files/folders? Thanks again, Brian --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: django/core/meta
Hi Brian -- Django's actually undergone some pretty sweeping changes since you last played with it. Probably the best place to start is by reading the 0.95 release notes (http://www.djangoproject.com/documentation/ 095_release_notes/) for an overview of what's changed. That page will eventually lead you to http://code.djangoproject.com/ wiki/RemovingTheMagic, which describes is gory details all the changes since last time you checked out Django.

django/core/meta
Hi all, I dowloaded django for the first time about a month and a half ago and today tried this line: from django.core import meta but keep getting this error: Error: cannot import name meta. Are you sure your INSTALLED_APPS setting is correct? When I browsed the directory I found that the meta folder does not exist in my django/core. Do I have to download this from somewhere or move it from another location? Any help you can give me would be great.
