Custom Login View

[Happy Rob]

Hi guys

I'm trying to make a membership site but I'm struggling a little and would love a little help

# 1. How can I select where go if login fails? Can I add something next to the 'next=URL' that's similar?

# 2. How can I select so uses c/b/b3 to login instead of c/default/user/login?

# 3. When I login, it logs me out instantly - how can I not logout instantly?

I'm on Pythonanywhere, and I've got an app called "c"

APP: c

------------------------------------------

MODEL: a.py...

db = DAL ('sqlite://storage.sqlite')

from gluon.tools import Auth

auth = Auth(db, controller='b')

auth.settings.controller = 'b'

auth.settings.on_failed_authorization = URL('c',args='b/b3')

auth.settings.login_url = URL(request.application, 'c', 'b3')

auth.define_tables(username=False,signature=False)

------------------------------------------

CONTROLLER: b.py...

#home page

def b1():

    display_page = XML('<h1>Home Page</h1>')

    return dict(display_page = display_page)

#regn page

def b2():

    display_page = XML('<h1>Registration Page</h1>')

    return dict(display_page = display_page, form=auth.register(next=URL('b3')))

#login page

def b3():

    display_page = XML('<h1>Login Page</h1>')

    return dict(display_page = display_page, form=auth.login(next=URL('b4')))

# 1. How can I select where go if login fails? Can I add something next to the 'next=URL' that's similar?

#members page

@auth.requires_login()

# 2. How can I select so uses c/b/b3 to login instead of c/default/user/login?

def b4():

    auth.settings.login_url = URL('b', 'b3')

    display_page = XML('<h1>Members Page</h1>')

    return dict(display_page = display_page, form=auth.logout(next=URL('b1')))

# 3. When I login, it logs me out instantly (and sends me to b1) - how can I not logout instantly?

------------------------------------------

VIEW: b/b1.html...

{{=display_page}}

VIEW: b/b2 and b3 and b4 are the same...

{{=display_page}}

{{=form}}

------------------------------------------

Any help would be greatly appreciated - especially with question 2.

1. By analysing the web2py's code I find this line:

https://github.com/web2py/web2py/blob/master/gluon/tools.py#L1520

Basically you should define a url to redirect when login fails. And internally açthe parameter ( next=??) that you want to do.

https://github.com/web2py/web2py/blob/master/gluon/tools.py#L4309-L4311

Steps:

1.1 Search by "fail login" string.

https://github.com/web2py/web2py/blob/master/gluon/tools.py#L1520

1.2 Here it call the function call_or_redirect.

https://github.com/web2py/web2py/blob/master/gluon/tools.py#L4310

1.3 That call a function and redirect

https://github.com/web2py/web2py/blob/master/gluon/tools.py#L93

That you can pass a url in string format or a function URL() using parameters..

I don't was tested but I think that it so:

auth.settings.on_failed_authentication = URL("YOUR ACTION")
or
auth.settings.on_failed_authentication = "YOUR ACTION"

2. In these section have what you want.

:

http://web2py.com/books/default/chapter/29/09/access-control#Authentication

Especifically this code:

def mylogin(): return dict(form=auth.login())
def myregister(): return dict(form=auth.register())
def myprofile(): return dict(form=auth.profile())

You can expose auth action that youself created .

3. Logout instantly?

SOLVED!!!!

Hi Marlysson

Thanks for your help

In the end I didn't need to do any defining or anything too much.

For 1 (failed login), I put the auth settings into the controller instead of the model

For 2. (selecting login page) I also put the auth settings into the controller

For 3. (logout) I just put the logout into a separate view.

So in the end, here is the complete membership site  - yay!

To access, go to https://XXXXXX.pythonanywhere.com/c/e/b1

App: C

Model: a.py

db = DAL ('sqlite://storage.sqlite')

from gluon.tools import Auth

auth = Auth(db)

#to access, go to https://XXXXXX.pythonanywhere.com/c/e/b1

#setting stuff

auth.settings.controller = 'e'

auth.settings.on_failed_authorization = URL('e', 'b1')

auth.settings.login_url = URL('b3')

#home page

def b1():

    display_page = XML('<h1>Home Page</h1><a href="b2">Registration</a><br><a href="b4">Login to members</a>')

    return dict(display_page = display_page)

#regn page

def b2():

    display_page = XML('<h1>Registration Page</h1><a href="b4">or Skip this page and Login to members page</a>')

    return dict(display_page = display_page, form=auth.register(next=URL('b4')))

#login page

def b3():

    display_page = XML('<h1>Login Page</h1>')

    return dict(display_page = display_page, form=auth.login(next=URL('b4')))

#members page

@auth.requires_login()

def b4():

    display_page = XML('<h1>Members Page</h1><a href="b5">Logout</a>')

    return dict(display_page = display_page)

def b5():

    display_page = XML('<h1>Logging Out</h1>')

    return dict(display_page = display_page, form=auth.logout(next=URL('b1')))
