At the link above it explains how to send a user off to sign-in or
register in a python script. The code below does what I want, but I
don't know how to do the same thing as an html hyperlink on my
applications "home" page. Not all users need to login to proceed
further into my application, only those who want to create their own
map.
greeting = ("<a href=\"%s\">Sign in or register</a>." %
users.create_login_url("/"))
self.response.out.write("<html><body>%s</body></html>" % greeting)
Thanks,
Brian in Atlanta
Btw if you want to play with my app, it is at
http://carpoolfinder.appspot.com
There is a sort of a sandbox that does not require a sign-in if you
enter "Tester" (without quotes) in the inital text field.

Ok, I am getting no response, so let me say what my attempt was, based
on viewing the source html of a GAE webpage. But this "attempt" does
not work, because I get sent to a nonexistent webpage. Notice that the
return address is the one for my appspot.com application.
<form id="gaia_universallogin"
action="https://www.google.com/accounts/LoginAuth?continue=http
%3A%2F%2Fcarpoolfinder.appspot.com%2F" method="post"
onsubmit="return(gaia_onLoginSubmit());">
<input type="hidden" name="continue" id="continue"
value="http://carpoolfinder.appspot.com" />
<input type="submit" class="gaia le button" name="signIn"
value="Sign in"
/>
</form>

I guess you can just do a redirect to the url generated by users.create_login_url("/") from your handler when user clinks on the link in your home page.--

You just create an ordinary link using the value returned by
users.create_login_url("/") as the link location, and display the link
only if users.get_current_user() is None.

I don't quite get it. I hope if by seeing the existing form on the
page and my attempt at following your suggestions, you can spell out
more specifically what you mean Geoffrey and Gipsy.
This is the existing form.

<input type="text" name="place" id="placename" />
<input type="submit" value="Submit short group name" />

I assume that,your requirement is ,when the user submit the form:
<form method="get" action="/">
<input type="text" name="place" id="placename" />
<input type="submit" value="Submit short group name" />

You want them to be taken to the login page if they are not already logged in ?
If my assumption is correct, then as Geoffrey said ,check if users.get_current_user() is None and if true re-direct to the login url

No, I want the people who do login to return to this home page. If the
form entry is not empty it would be Ok for them to be sent on "/?

Okay.
Then from your handler for '/' check if users.get_current_user() is None if true then redirect
(DO NOT write the response back), to the url generated by users.create_login_url("/")
code will be something like
'
....
...
self.redirect(users.create_login_url("/"))
....
Or you can write back the below html snippet
"""<html><body onload='location.replace('"""+users.create_login_url("/")+"""')></body></html>"""--

Gipsy,
I don't think that the first option will work because I cannot assume
that the person who arrives needs to be a user. Non-users can also
arrive at my home page and enter a "place" in the text field, but I
want to treat users differently from non-users.
But I want to give users a chance to login from my home page, because
I don't know what else to tell them to do to login at that point. How
does anyone login at appspot without being invited to do so? Can you
just initiate a login? If so, I can give users instructions for a link
to where they can do so, and tell them when they are through to come
back manually. But I don't know where to tell them to go.
I don't understand the second option, but I assume it does not achieve
my needs, either, does it?
Thanks so much for helping on this.

Somewhere in your handler for /:
if users.get_current_user() is None:
self.response.out.write("<a href='" + users.create_login_url('/') +
"'>Click here to login</a>")
When a user clicks the resulting link, they'll go to the login page,
log in, and get sent back to your page, where the login link won't
show anymore.

Geoffrey,
Yes, but that seems to assume that the user MUST login, and only users
who need to login for the result they wish to achieve, need to login.
If you can tell me a link to where I can send people who get to my
application home page and wish to login, can go, I can enter that link
for them to click and I can tell them to come back to my page (with
the back button?) when they complete login. But I don't know where to
send: what URL link would I give them?
Thanks,
Brian in Atlanta

If you let your users click the url generated by users.create_login_url('/xyz') it will take the users to the google' account login page and after successfull completion of login , google automatically redirect the user to the url you have provided ('xyz' in this case).

Gipsy,
It is a consequence of my chosen design, to allow both "clients" and
"organizers" to enter the app via the same door. This way the
organizers can identify themselves before they enter the app so that
they need not be asked later who they are, because I was having
difficulty coding something like a javascript-confirm-dialog in
python, to ask that question, so I elected to do it this way. I didn't
anticipate that this would be difficult, but it was pretty hard to do,
too, as it turned out. My knowledge of oop and client/server
programming is very limited, as you might have deduced. The only way I
was able to build the organizer's wrapper on this application was that
I stumbled on a coding genius who took me under his wing in an all day
Saturday Google hackathon. All I had coded was the client's system
when I arrived at the hackathon and when I left I had the organizer's
portion, but it did not quite work the way I wanted, so I have been
tweaking it ever since.
Is that more than you wanted to know? Is that an answer to your
question?

anticipate that this would be difficult, but it was pretty hard to do,
too, as it turned out. My knowledge of oop and client/server
programming is very limited, as you might have deduced. The only way I
was able to build the organizer's wrapper on this application was that
I stumbled on a coding genius who took me under his wing in an all day
Saturday Google hackathon. All I had coded was the client's system
when I arrived at the hackathon and when I left I had the organizer's
portion, but it did not quite work the way I wanted, so I have been
tweaking it ever since.
Is that more than you wanted to know? Is that an answer to your
question?

links at runtime; I don't believe there's any guarantee that these
hardcoded links will keep working if Google changes the login system,
and the users API specifically includes functions that return the
correct URLs so you don't have to hardcode them.
I'm not sure why you think hardcoding in the link rather than
generating it at runtime has anything to do with the ability to not
require people to click it. It still just shows up as a link on a
webpage.

Geoffrey,
It is not my desire to hardcode the urls, but I don't know how not to;
my programming skills are limited. Or maybe I have not understood the
suggests given here by you folks about how to do it in a way that is
not hardcoded.
The path a user takes in my application depends on whether s/he is
logged in or not, and if logged in, whether s/he goes to a map s/he
created or not. If a person has a google account, s/he may not want to
use the app as if s/he does, because s/he will see different results
from her/his users.
On top of that, the users only interface with the app is via html
pages, not python pages, so I don't know how to put links that change
or appear and disappear according to user responses, into an html
page. If I were to wait to ask the user about his/her logging
preference at key times while the python program is in control, that
would be ok, but I don't know how to do that in a way that keeps the
html page visible in the background the way a javascript confirm
dialog produces a little popup dialog window; that's my first choice,
but I don't know how.
My inclination is more toward developing another related app now, but
I would be pleased to learn how to code a softcoded link if you or
others can explain it to me.
Thanks very much for expressing your question.

Do you use (Django) templates?
If not start using them, separate the function (code) from the
presentation (html)
Read the GAE example
http://code.google.com/appengine/docs/gettingstarted/templates.html
There they show you how to use the
users.create_logout_url()
users.create_login_url()
methods in templates, read the Django doc about templates for version
0.96 for more things you can do.

Well, my guru used Django templates, but I just used his {{...}}
tricks and never read the material use recommended. Now I have and I
see what you mean. I'll make a concerted effort to implement that with
my home page as you recommend. Thanks very much.
