[web2py] auth.requires_login() inside a view

[elffikk]

hi,

I need to display a form (similar to a blog post), but only when a
user is registered,
but the page should be displayed even if user is not authenticated,
except the form

#a list of posts

{{if auth.user:}}
        {{=form}}
{{else:}}
        <h3>{{=T('Posting messages requires login')}}</h3>
        {{=auth.navbar()}}
{{pass}}


the problem is that after login it is not redirected to that page

any help?

thank you
