Problem with auth_login: too many redirects

[man24]

Sorry for reposting the question.  I am following the 'wiki' example given in the web2py book.  After first implementation, it worked fine, however, now when I click on any action that requires login or even clicking the 'login' from the top menu, I get this response from my web browser:  'too many redirects occurred when trying to open'.  Any idea what could be wrong.  The 'wiki' app was working fine yesterday and I haven't made any changes and now today it's giving this problem.  BTW, I am running web2py on a mac.  Thanks for your help.

Can you post your exact code (models, controllers, views)?

[man24]

Here is the model file - > db2.py 

# coding: utf8

db.define_table('page',

        Field('title', requires=IS_NOT_IN_DB(db, 'page.title')),

        Field('body', 'text', requires=IS_NOT_EMPTY()),

        Field('created_on', 'datetime', default=request.now, readable=False, writable=False),

        Field('created_by', db.auth_user, default=auth.user_id, readable=False, writable=False),

        format='%(title)s')

        

db.define_table('comment',

        Field('page_id', db.page, readable=False, writable=False),

        Field('body', 'text', requires=IS_NOT_EMPTY()),

        Field('created_on', 'datetime', default=request.now, readable=False, writable=False),

        Field('created_by', db.auth_user, default=auth.user_id,readable=False, writable=False))

        

db.define_table('document',

        Field('page_id', db.page, readable=False, writable=False),

        Field('name', requires=IS_NOT_IN_DB(db, 'document.name')),

        Field('file', 'upload'),

        Field('created_on', 'datetime', default=request.now, readable=False, writable=False),

        Field('created_by', db.auth_user, default=auth.user_id, readable=False, writable=False),

        format='%(name)s')

Here is the controller: 

def index():

    pages = db().select(db.page.id, db.page.title, orderby=db.page.title)

    return dict(pages=pages)

    

@auth.requires_login()

def create():

    form=crud.create(db.page, next=URL('index'))

    return dict(form=form)

    

def show():

    this_page = db.page(request.args(0)) or redirect(URL('index'))

    db.comment.page_id.default = this_page.id

    form = crud.create(db.comment) if auth.user else None

    pagecomments = db(db.comment.page_id==this_page.id).select()

    return dict(page=this_page, comments=pagecomments, form=form)

@auth.requires_login()

def edit():

    this_page = db.page(request.args(0)) or redirect(URL('index'))

    form = crud.update(db.page, this_page, next=URL('show', args=request.args))

    return dict(form=form)

    

@auth.requires_login()

def documents():

    page = db.page(request.args(0)) or redirect(URL('index'))

    db.document.page_id.default = page.id

    db.document.page_id.writable = False

    grid = SQLFORM.grid(db.document.page_id==page.id, args=[page.id])

    return dict(page=page, grid=grid)

    

@auth.requires_login()

def user():

    """

    exposes:

    http://..../[app]/default/user/login

    http://..../[app]/default/user/logout

    return dict(form=auth())

Here are the views:

@auth.requires_login()
def user():

Don't require login to get to the user() function -- if you're not logged in, it redirects to the user() function, which will result in an infinite redirect loop.

Thanks Anthony.  Everything is working fine now!
