Mike,

The primary disadvantage of storing navigation state in the session,
or, for that mater,
in variables sent in a POST, is that, for example, a user emailing the
url to their spouse
("Hey, honey, look at this one!") isn't going to work.  If you are
concerned about long
urls, you could always compress them and then uuencode the value and
use that in the
url.  Better probably would be just use a database primary key for the url part.

Remember that people often represent their best work, and I bet they  
only answer the questions they're most confident about their  
experience with.

If you care that much about your code, you'll be fine -- once you have  
your 10,000 hours* in as a coder, people will be in awe of your code  
too.

My only dissatisfaction is that other contributors to this list seem
to do almost anything with very few lines of code, whereas I am using
many.  And, being a newbie I naturally worry that I am on the wrong
pathway, having missed the turning.
Thanks to both for your reassurance.

Your current approach makes sense. If you're concerned that you're  
storing too much data in the session, you could just maintain a  
session ID in the session and use that as a key for an sqlite3  
database or something, or even a model in your app's database, if that  
makes sense. Is there any reason you're unsatisfied with the way  
you're doing it?

Mike,

I think you're doing it right. Unless you want that data to be in the
URL (perhaps) or sent page to page in post data (probably a bad idea)
sessions are your best option.

How to pass values between views/templates

[adelaide_mike]

Hi
In my app the user needs to drill down through a series of templates
and their views to identify a house.  We start with the city, then the
street and finally the house, in each case chosen from a rendering of
the possible values selected from the relevant database table.

I have all this working nicely using request.session['insert value
here'] as the tool for storing the choices as they are made.

My question is: is there a better or more proper way?

Mike
