Fail login doesn't return an errorm msg

[Yannick]

hello mate,
I wonder because I noticed that in auth, when the user fails to login
(enter a fake username and password) there is no error message
returned...

Here is a small code

######### Model
auth.settings.table_user = db.define_table(
db.Field('email', length=128,default=''),
db.Field('password', 'password', readable=False,label='Password',
requires=CRYPT()),
migrate=False)
db.auth_user.email.requires = [IS_EMAIL(), IS_NOT_IN_DB(db, '%s.email'
%
auth.settings.table_user._tablename)]

######### Controller
def login():
return dict(loginform = auth.login() )

######### View
<h2> {{if loginform.errors.email:}} Email {{=loginform.errors.email}}
{{pass}} </h2>
<h2> {{if loginform.errors.password:}} Password
{{=loginform.errors.password}}{{pass}} </h2>
<h2> {{if loginform.errors.error_message :}} Invalid {{pass}} </h2>

<br/>
<br/>
{{=loginform.custom.begin}}
<table>
<tr>
<td>Emailing:</td>
<td>{{=loginform.custom.widget.email}}</td>
</tr>
<tr>
<td>Password:</td>
<td>{{=loginform.custom.widget.password}}</td>
</tr>
<tr>
<td>{{=loginform.custom.submit}}</td>
<td></td>
</tr>
</table>
{{=loginform.custom.end}}



I when to capture the error message of the failure using
"form.error.XXX" not through session.flash...

Please let me know if you have any hints...

Usually when I see this it is because of a double redirect and the
response/session.flash is lost.

Yannick,

I just tried it on one of my sites and I got "Invalid Login" flash message.

I had the same issue on one of my forms not showing field validation
errors. It was as mr.freeze indicated, a double redirect that was
causing this .

Hmm interesting, thanks for the note... I don't think I'm doing a
double redirection in my code though... can you please let me know how
you resolved that issue when you had it >

Thanks,
Yannick P.

Sorry, I'm not sure exactly when/where I made this change in the last
week. You can use wingide and check what the repsponse.flash is
between function calls.

Thanks for your help...

You mentioned you are not using session.flash - why not? have you
checked response.flash and session.flash in a debugger to see what
might be happening to the .flash between function calls?

Add a

print request.function

to your model and check if there is a double redirect.
The other possibility is that sessions are not working.

[Yannick]

Hello thanks for the note...

I did add "print request.function"
and Yes there is a double redirection because the output print the
function login twice :
login
login

I wonder how to fix this double redirection here is one of the setting
I have in my controller:
auth.settings.login_next=URL(r=request, f='profile')

Do you have any idea... I'll keep debugging...

[Yannick]

I tried the solution in this thread but unsuccessful:
http://groups.google.com/group/web2py/browse_thread/thread/9e2441a938368b3a/451cfaf61e60a731?lnk=gst&q=double+redirect#451cfaf61e60a731

Anyway idea ?

comment this out just to see what happens...

or use wingide and see where it goes.

[Yannick]

Yes I did comment this out "auth.settings.login_next=URL(r=request,
f='profile') "
but still same old, the double redirect is still there... I really
wonder what trigger that double redirection... there is nothing extra
I'm doing here, I fulling using Auth API... Hmmm...

For debugging purposes....

1) try replace everything in the view with {{=loginform}}

2) try print request.function, request.vars

what do you see?

Feel free to send me your code and I will take a look.

Hello Massimo, thanks for the note...
i did follow your instructions which was :
1) I put this in the view {{=loginform}}
2) I print request.function and request.vars from the model
And here is what i see:
login
<Storage {'email': 'sdfs...@efsdf.cfd', '_formkey':
'440a019c-1479-4b0d-8e86-b27c0496dd7a', 'password': '12w12123',
'_formname': 'login', '_next': ''}>
login
<Storage {}>

It looks like there is a double redirect...

I did create a small brand new application just to test the login with
Auth using the web2py admin console ( Just to double check that is not
my code which cause this) and I have the same result...

I'll send you the code that I used to test it... I really don't know
why that happen, I think it use to work in the pass...

Thanks for your help...

Cheers,
Yannick P.

Hello Massimo,
Thanks I just test the new release and realized that the double
redirect seem to be fixed on the Auth - Login.... I just wonder what
was the root of the issue I got in the previous release...

Thanks

I do not know. Glad it is fixed anyway.

[Yannick]

Hmmm Think there is an issue with this release... Please take a look
to the ticket generated after a user tried to login using a fake
password:

Anyway idea ?

Yannick P.

[mdipierro]

fixing this tonight

[mdipierro]

I think this is now fixed in trunk. Can you confirm?

[Yannick]

Thanks for the note... I'll test and confirm it late this afternoon...
Tks

[Yannick]

I just test it and the error I got in 1.74.1 has been fixed...
Thanks... However the double redirection issue is still pending...

I tried to print this in the model : request.function and
request.vars and here is the result when I submit the form:
login
<Storage {'email': 'asd...@blablaba.com', '_formkey':
'7c6c9864-567e-4aec-9339-86b554b031ce', 'password': 'aaaaaaaaa',

'_formname': 'login', '_next': ''}>
login
<Storage {}>

You can see there is a double redirect...

I put a break point in the login function inside tool.py and watch the
"session":
the session.flash looks to be empty like session.flash = u""
And at the end of the process (break point finish) the value of the
session said "error evaluating" like :
session = <error evaluating>

I'm really running out of idea about debugging this issue... It used
to work with early previous version of web2py... Is anybody has an
idea or already have this issue ?

Thanks for your help...
Yannick P.

[Yannick]

Hi Massimo,
I just sent you the application so that you can reproduce this
error...

Thanks again,

Hello Massimo,
Just wonder have you been able to reproduce the scenario ? If yes any
hints ?

Thanks for your help...

[Yannick]

I just test back this issue using the latest version of web2py and
still I have a double submission, I don't have any feedback message
coming from the session...

Here is my development environment:

OS : Mac OS X Version 10.6.2
Python : 2.5.4
DB: PostgreSQL 8.4
Web2py : 1.74.5
Wing IDE Professional 3.2

Do you please have any any hints that can help here ? I'm desperately
looking for a solution or hints...

Thanks a lot for your help...

Yannick P.
