Thanks a load!  You've cleared up a lot!

Yes, I have read through the tutorial.  I even wrote a shortened version of 
it to act as notes as I learn:  http://polydoo.com/code/?p=48  (my blog)

Thanks again!

Re: Major Trouble Understanding Sessions Documentation

[Marcin Tustin]

This is how you store data:
 request.session['member_id'] = m.id
This is how you read it:
 request.session['member_id']

Your view code looks fine, in respect of how you use sessions. I can't see
that you have explained what problem you are having: what is going wrong?

Finally, you do have to do some minimal configuration to enable sessions.
Are you sure you have done that?

 So, you didn't understand the documentation, but you also don't want to
 be told what dictionaries/lists/tuples are.  How about you tell us which
 bit of the examples under "Using sessions in views" (which I'm not linking
 to because you've said you've read it) you didn't understand?

I don't understand why you think you need to know these things in order to 
use sessions. If you want to understand how assigning to a session is 
implemented, you're free to dive into the code itself. But that's literally 
*all you need to do* in order to use the session in the view (assuming 
you've followed the rest of the instructions on that page, eg added the 
middleware).

The only thing you need to do to make sure the session middleware is
properly configure it. It needs some sort of a storage (such as database,
file, cookies which are limited, etc...). You'll also need to make sure the
session middleware is included in your middleware configuration. This
configuration would exist under your settings.py and I believe is enabled
by default when creating new projects; at least that's been my experience
with Django 1.3+.

Keep in mind that these do use cookies, no matter what, so you will need
them enabled in whatever HTTP Client (browser, or what-not) you use.

Two links for enabling and configuring sessions (both on the same page,
these are anchor links).

Enabling Sessions:
https://docs.djangoproject.com/en/dev/topics/http/sessions/?from=olddocs/#enabling-sessions
Configuring Sessions:

how to check whether a certain variable is available from the session.
Since I'm not sure which part your looking for information on, I'll give
you information on both:

To check if a particular object exists within the current session, follow
the example under __contains__(key) which actually does not call "contains"
but instead uses "if x in request.session":
https://docs.djangoproject.com/en/dev/topics/http/sessions/?from=olddocs/#using-sessions-in-views

To check whether a current user is authenticated (logged in), you could use
this example:
https://docs.djangoproject.com/en/dev/topics/auth/#authentication-in-web-requests

Retrieving Form Data is actually one of Django's extremely strong points
(in my opinion) although it does require a bit of a learning curve. Once
you get it down, it takes off a huge burden; especially when coming from
other frameworks that don't offer as much validation built in. Basically,
you subclass a Form, create an instance of your form in the view while
passing it the POST data, and it will validate that data. Then, you can
simply do some flow-control based upon "if form.is_valid()".

Handling the data on another view is sort of a vague question. I'm not
quite sure what you mean by this one but please feel free to elaborate and
I'll see if I can give you some more info here.

Weird. Most people just suggest reading the Tutorial. Have you given that a
shot? It really does help with diving into the functionality and doesn't
take too long considering the large amount of knowledge you gain about
Django from it.

Re: Major Trouble Understanding Sessions Documentation

[Gregory Thompson Jr.]

Then how do I use the session to pass data between views?  What's wrong 
with my code?

If it counts for anything, *'text'* returns *'None'* in my debug statements 
(in the results() view).

What's confusing about this? You don't explicitly create sessions, and they
last as long as they are configured to last, which by default is until the
session cookie is cleared.

Re: Major Trouble Understanding Sessions Documentation

[Gregory Thompson Jr.]

   
   1. def login(request):
   2. m = Member.objects.get(username=request.POST['username'])
   3. if m.password == request.POST['password']:
   4. request.session['member_id'] = m.id
   5. return HttpResponse("You're logged in.")
   6. else:
   7. return HttpResponse("Your username and password didn't match."
   )
   
How about that for starters?

The documentation goes from that to explaining how to set cookies.  How do 
they expect me to understand what's going on?
There's absolutely NO explanation of what's going on in that code.  

request.session['member_id'] = m.id 

How the hell does that work?  

They don't tell you where the session is started, how, what the scope of 
the session declaration is, etc...  

http://www.youtube.com/watch?v=YFd9NLZFmvo=1=PL6CB0A9FA1D9C736A=results_video
  
 

See that video?  The video shows you how to use sessions very quickly.  How 
did the person in the video get ALL of that code from just the 
documentation? 

If all readers in this thread and kindly tackle each point I made, I 
promise you your own KFC when I start my empire.  Until then, I really just 
need someone to give me the step-by-step on this one.  I'm completely new 
to the framework and the documentation thus far has not been helpful.  I've 
mainly gotten by with the help of StackOverflow, IRC, and random code 
snippets online -- and occasionally, some outdated books.  

If you don't want to explain or aren't going to ask me progressive 
questions with regards to my confusion, please just skip over my plight.

Thank you all.

So, you didn't understand the documentation, but you also don't want to be 
told what dictionaries/lists/tuples are.  How about you tell us which bit 
of the examples under "Using sessions in views" (which I'm not linking to 
because you've said you've read it) you didn't understand?

Okay. What?

Can you explain any of the key points I was trying to understand?  I don't 
know what I'm doing.

In your template you can access the session variables as request.session.text.

Major Trouble Understanding Sessions Documentation

[Gregory Thompson Jr.]

I'd like to pass form data from one view to another.  

Here's my attempt: 

*#Models.py*from django import forms
class Textizer(forms.Form):
to_textize = forms.CharField(max_length=100)

def __unicode__(self):
return self.to_textize
*#views.py*from textize.models import Textizerfrom django.http import 
HttpResponseRedirectfrom django.shortcuts import render_to_responsefrom 
django.core.context_processors import csrf
def index(request):
if request.method == 'POST':
form = Textizer(request.POST)

if form.is_valid():
request.session['text'] = form.cleaned_data['to_textize']
return HttpResponseRedirect('/results')

else:
form = Textizer()

c = {'form': form}
c.update(csrf(request))
return render_to_response('C:/Documents and 
Settings/quansai/projects/textsite/templates/index.html', c)
def results(request):
text = request.session.get('text', None)
c = {'text' : text}
return render_to_response('C:/Documents and 
Settings/quansai/projects/textsite/templates/results.html', c)


I really don't understand the following, and I've read the documentation over 
and over.  I've been on this for two days:


   - How to initiate a session
   - How sessions are checked
   - How to retrieve form data from one page to handle the data on another.

Again, I've read through the documentation.  I've asked on IRC but everyone 
pretty much just says "RTFM" even when I tell them I have.  This is absolutely 
frustrating as an extreme beginner.

I'd also like to add that I DO understand the core Python language.  Please, 
unless it's absolutely necessary, don't try explaining to me what a dictionary, 
tuple, list, etc... is.  I've already had my intelligence insulted by the users 
on IRC in this regard.  I really just don't understand the sessions 
documentation.
