[Solved] IUserLoggedInEvent - Not able to redirect

ngoeddel · July 24, 2020, 8:18am

Hi,

I want to redirect users according to their group membership. Therefore I added the code found here: https://docs.plone.org/develop/plone/sessions/login.html#post-login-actions to my addon and modified it a bit.
Using logging I can see that it gets executed after every login but the redirect does not work. Even if I use request.response.redirect(url, lock = True). How can I convince Plone to redirect to the URL I want after every login?

Have you checked this?

We are running it in Plone 4.3. We configured a redirection to a custom browser view that performs some redirection based on some user constrains like group membership or roles.

We are running Plone 5.2 and Python 3.8. Sorry, I thought the tags were enough to make that clear. collective.onlogin seems not be tested on Plone 5 or Python3.

He probably meant looking at the code and see what collective.onlogin does.

For example, it uses request.RESPONSE.redirect (https://github.com/martinschoel/collective.onlogin/blob/024a6e1aab943270d9537bde16fbbff6b4521f4c/src/collective/onlogin/events.py#L77) and two event handlers https://github.com/martinschoel/collective.onlogin/blob/024a6e1aab943270d9537bde16fbbff6b4521f4c/src/collective/onlogin/configure.zcml#L30-L40.

Maybe these two handlers are what you need to do as well?

You can use plone.login. Works on Plone 5.

plone.login was merged into Products.CMFPlone in 5.2.

Look at

github.com

plone/Products.CMFPlone/blob/master/Products/CMFPlone/browser/login/login.py#L206


        handler()


def force_password_change(self):
    handler = queryMultiAdapter(
        (self.context, self.request),
        IForcePasswordChange,
    )
    if handler:
        handler()


def redirect_after_login(self, came_from=None, is_initial_login=False):
    adapter = queryMultiAdapter(
        (self.context, self.request),
        IRedirectAfterLogin
    )
    if adapter:
        came_from = adapter(came_from, is_initial_login)
    if not came_from:
        came_from = self.context.absolute_url()


    self.request.response.redirect(came_from)

So implementing a IRedirectAfterLogin multi adapter bound to your browser layer (which is an interface on the request) returning an url to redirect to on call will do it.

That sounds promising. Could you show me a minimal example of that, please?

jensens · July 24, 2020, 11:12am

It seems it is only documented in the Upgrade Guide here https://docs.plone.org/manage/upgrading/version_specific_migration/upgrade_to_52.html#new-login

We definitely need to move/copy this information to a better place docs.plone.org, any takers?

This works great. Thank you!

I am looking for such a solution, can you share the complete implementation?

ngoeddel · July 27, 2020, 10:56am

@Heiko It is just what you can see behind the link of @jensens.
The __call__ method has to return the address you want to redirect to.

FYI, in Plone 5.2 (might affect other versions also) using modal login, there is an issue in mockup/plone.app.layout that disregards the backend redirect response if the response URL includes a view i.e. /@@some-view. For more info:

Adapters providing IRedirectAfterLogin can not redirect to views

01 type: bug

## BUG/PROBLEM REPORT (OR OTHER COMMON ISSUE)  ### What I did: In the `__call__` method of a `IRedirectAfterLogin`, returning an arbitrary URL is supposed to redirect to that URL. This works most of the time. But when returning a view name, with or without `@@`, it redirects to the home page. See https://github.com/fulv/collective.onlogin/blob/python3/src/collective/onlogin/adapters.py#L119 ### What I expect to happen: For example, returning http://localhost:8080/Plone/@@personal-information, I expect to be redirected to the user's "Personal Information" page. ### What actually happened: Instead, I get redirected to the home page. ### What version of Plone/ Addons I am using: 5.2 https://github.com/fulv/collective.onlogin/tree/python3
