Thanks for that - I'll do some testing.
I'm also thinking of middleware to look at the request and discover the
company on the way in so I can make it available to everything which
processes the request and produces a response.
Cheers

Managers operate on your model, so their methods usually call sgl

As an example, assume a blog app with a Post model which, among other
things has a BooleanField called 'draft'.
You could then write a custom manager called PublishedManager that

If you've used the '.objects' attribute of a model you've used a manager.
A custom manager would be a subclass of the standard manager. You can

Not very nice, since there's no delete-related, no signalst etc.
I don't think delete can be fixed for multiple databases without

Just as a follow-up. I ended up switching to Elixir to handle
my multiple legacy databases, while keeping django to handle
the main system. The syntax is very similar, and it provides
some additional flexibility that allows me to deal with those

Hello,
Anyone can give us a hint with this?
I have the same problem: with a custom manager (for a 2nd database)
SELETs and INSERTs are working, but not the DELETE operation.
Seems like DELETE references a global connection variable (to the main
database).
Thanks

H'ok, got this working. First off, I had a brain hiccup: my model was
one-to-many (the actual model is more complicated than my Book
example; I just used the Book to illustrate my point).
What I ended up doing was basically what you suggested to do using

I'm really not the one to be walking you through this, since my own

I read that post, and now have a general idea of what to do, but I'm
still confused on the specifics. It doesn't help that my SQL is VERY

Am I supposed to use cursor.execute() to do the INITIAL lookup? That
is, instead of calling a filter, or whatnot, on each book entry, I do
a cursor.exec

I could, but I need to do it in a template, and from what I
understand, passing variables to method calls in the template language
is a pain, or at least ugly. I think a custom manager is the elegant,
"proper" way to so it (someone can correct me if I'm wrong.

Since my_book.auther_set.all() returns a QS, can't you just say
something like ...all().filter(author__isalive=True) or something like
that? I've never tried, but I thought that django would figure it
out?

Hi, again
Found a solution which doesn't seem to be documented:
If you need a special manager for the admin interface, then you should
add this one to the Admin class of your model:
class Admin:
manager = MyManager()

Never mind, I figured it out. I put the import inside the class instead

Not that way anymore. I will just check (in the middleware) if the
requested entry's author is the logged in user (for edit action) if not

You're right - my fault.
It just isn't the way I would like to handle this problem.
But I've forgotten about middleware and I think this will be the best
way to solve this _issue_ without breaking MVC(MVT) schema (just check
if the requested object was created by user).

But Luke *is* proposing to do this in a manager. The middleware just
makes the current user available in the model/manager. (if you want it
to be)
Rather than a hack, the functionality that his middleware module
provides seems to me a missing part in a mostly very pragmatic
codebase, but I digres
But it's some kind of a hack that I don't want to have in my app.
It's easy to achieve this by get/filter in views - but manager would be
more secure(error-proof).
