[web2py] Re: Auth.user is still NULL after a successful login
Hi,
I studied the source code of auth.login() and found that all the
validations are applied within the login method itself. The error message
is automatically written to an element of class flash via setting
session.flash to auth.messages.invalid_login.
I modified my view code to include the class attribute of the and set
its value to "flash" as below:
{{=response.flash}}
Now one can modify the CSS and JS to control how the element is displayed.
As far as I understand, to achieve the required functionality of displaying
form errors via form.errors.email etc., one can either extend Auth and
override the login() method or build a custom login functionality.
Let me know if there is an easier way

I added the above code line in controller. The attribute id was added to
the form element, but the whole being tag was rendered as :
*"*
*"*
*
*
i.e form is displayed a text element and hence JS was not working on it.

I didn't want to render the element dynamically, so I tried the
following:
{{if login_form.errors:}}
{{=login_form.errors.email}}
{{pass}}
But nothing is happening.
In usual cases, if I leave the field empty or enter an invalid email
address, an error is displayed but not in this case.
Even if there are errors, the *login_form.errors* object is empty and
nothing is displayed.
How does auth handle authentication errors ?

Ah, I forget that form.custom.begin is an XML object (more like a string)
and doesn't change when you directly manipulate the form object itself. You
could do:
f.custom.begin = '%s id="login">' % f.custom.begin[:-1]

{{=login_form.errors.email}}
{{pass}}

[web2py] Re: Auth.user is still NULL after a successful login
Hi,
I found a workaround to the problem. I need to assign the id "login" to the
form so that certain CSS and JS can be applied to the form elements. Since
I was unable to assign id to the form, I assigned the id "login" to the
table element. The login is now working.
But another problem has surfaced. Now whenever I enter correct the
credentials I am successfully able to login but whenever I enter
false credentials, I am unable to see any form errors.
How invalid login is handled by Auth ?
I want to show the error "Email/Password not matching" below my form. How
could I do that ?
My controller code is :
def index():
login_form = auth.login()
# Configure form fields
login_form.custom.widget.email['_value']='Email'
login_form.custom.widget.email['_data']='Email'
login_form.custom.widget.password['_value']='Password'
login_form.custom.widget.password['_data']='Password'
login_form.custom.submit['_value']='Login'
# Configure form properties
# login_form['_id']='login'
if login_form.errors:
login_form.errors.email='Email/Password does not match'
return dict(login_form=login_form)
In the view I have :
{{=login_form.custom.begin}}
{{=login_form.custom.widget.email}}
{{=login_form.custom.widget.password}}
Forgot Password?
{{=login_form.custom.submit}}
{{=login_form.custom.end}}

What's not working? When you view the HTML code of the rendered page in the
browser, is the id not there, or is it just that some client-side CSS or JS
isn't working as expected? If the latter, the problem could be that you
have put the form beginning and ending code inside the tags
rather than outside, where they belong. Should be:
{{=login_form.custom.begin}}

auth.login() handles it's own form processing, and it uses the session
when calling form.accepts (which adds a hidden _formkey field to the form,
which must be present upon form submission). In your code, you do not
return the form object to the view, which means your view cannot include
the hidden _formkey field, which is therefore not submitted with the form.
So, when the form is submitted, the form.accepts in auth.login() fails,
which means the user object is never stored in session.auth.user -- hence,
auth.user is None. The reason the login submission is successful is that
your index() function then does its own processing of the login form,
which
is successful -- but your explicit call to login_form.process() does not
do
anything to set auth.user, so it is never set.
In short, you should not be doing your own processing of the login form
-- let auth.login() handle that. And if you want to customize the form
display in the view, you still have to return the form to the view so you
can include the hidden _formkey and _formname fields in the form (you can
use form.custom.end to do that).

auth.login() handles it's own form processing, and it uses the session
when calling form.accepts (which adds a hidden _formkey field to the form,
which must be present upon form submission). In your code, you do not
return the form object to the view, which means your view cannot include
the hidden _formkey field, which is ther

That should work. Can you show the view code? Also, note you can just do: login_form['_id'] = 'login' Anthony On Monday, March 12, 2012 1:19:45 PM UTC-4, Sushant Taneja wrote: > > I tried customizing the form.

[web2py] Re: Auth.user is still NULL after a successful login
I tried customizing the form. I have to set the id of the form element to login. To achieve the above I used the following statement in controller: login_form = auth.login() # Configure form properties login_form.attributes['_id']='login' But it's not working. The generated form does not contain any id attribute. Is there another way to do it ?

Thanks for an explanatory answer. I will try this out.

In your code, you do not return the form object to the view, which means your view cannot include the hidden _formkey field, which is therefore not submitted with the form. So, when the form is submitted, the form.accepts in auth.login() fails, which means the user object is never stored in session.auth.user -- hence, auth.user is None. The reason the login submission is successful is that your index() function then does its own processing of the login form, which is successful -- but your explicit call to login_form.process() does not do anything to set auth.user, so it is never set. In short, you should not be doing your own processing of the login form -- let auth.login() handle that. And if you want to customize the form display in the view, you still have to return the form to the view so you can include the hidden _formkey and _formname fields in the form (you can use form.custom.end to do that).
