Hello

After redirecting user after registriation the flash message is not shown. if I print session the message gets lost --> flash is none

I inserted print session in my user function in default.py controller and in index function

This is the print result

session index <Storage {'flash': None, '_formkey[register]': ['cd76b587-db09-46fa-a05e-b31c2f71d4c4', 'ad7148b5-3306-455b-9c2d-65e6c91e9856', '069640cf-0c68-416c-b091-8e8efa337e24', 'd89158de-86a5-4e23-9a07-43ba042a09ac', 'fa1a99ba-8d97-49c2-ad0d-ffe7ba66e412', '5cfb4a89-8284-4879-9b1d-9bc923350771', '6b55ba7d-fa6f-4709-a8ca-0ec30e4f4455', 'c983f92b-10d6-47d7-b02f-a5bc7a4419b4', '7ff1a289-f9b4-47b6-92a2-da93fcdeb8ca', 'c298cda9-447b-47e4-b9b5-7b1a6f85645d'], '_formkey[login]': ['dc014554-b3a9-4ab7-8a4e-21600922d485', '4afe46f2-77a8-4e74-abc9-1d2d512a1d56', '3fa4d78a-4113-419f-ae90-5a39d3bac9f9', '171e7853-0f31-4e66-b8ef-1c8c665610b5', '86b76af0-3f51-4f47-95e6-903a117db2cb', 'f117d59d-7e38-4e90-a70c-fb9f507b3681', '756458fd-1f13-4aab-9f71-fae5322199c5', 'e5949f3d-3094-45f2-94ba-ff4c9ea27d08', '8abea09c-9493-499b-bf50-5487262a9a03', '467f8079-508a-4c83-bbf1-49ba86ade0f1'], '_formkey[auth_user/create]': ['5cf42aee-c3b1-4f2b-a4b5-6027ec55c7c3', '6a58a734-dc76-43b0-84df-fc35444a6364', '0cc70146-e946-411c-9ced-4552098a07c8', 'b189dc4c-d789-463b-a223-ce22bb880828', '4ebe96ab-1b25-4bcf-98bd-285f51b28168', 'd5f15dea-51c4-446e-a66e-f3aaccc3937b', 'a13cf1fe-a994-44e0-b03c-c5769f0d0d92', '7297c942-159e-491f-9a63-fc10420c1ebb', 'dbe6e93c-28e0-4b54-b4d5-3a0f4083059d', '199b91db-8921-42a2-a741-1dd323c09600']}>

also when redirected to index.html the session is printed twice

Any suggestions why this kind of behaviour?

Are you successfully able to show any flash messages (i.e., simply set response.flash within any action and see if it shows up on the page)? Is the appropriate DIV in the layout.html?

Note, by the time you are in the index function, session.flash is not expected to be there any longer, as the framework copies session.flash to response.flash after a redirect. Is there anything in response.flash at that point?

Flash is show on my index page so the position <div class="flash">{{=session.flash or ''}}</div> is ok
I just put session.flash('Some random text') in my index function and it works

But after registration the message is not shown

My code for user registration in index.py user

if request.args(0) == 'register':

    #form = auth.register()
    if form.process().accepted:

        #some code

        session.flash = ('Thank you for registering. Please check your e-mail account')

        redirect(URL(request.application, 'default', 'index'))

session.flash is not intended to work that way. You use session.flash only when you are doing a redirect, in which case, it gets moved from session.flash to response.flash after the redirect. So, the template should have {{=response.flash}}, not {{=session.flash}}.

My code for user registration in index.py user

if request.args(0) == 'register':

    #form = auth.register()
    if form.process().accepted:

        #some code

        session.flash = ('Thank you for registering. Please check your e-mail account')

        redirect(URL(request.application, 'default', 'index'))

How is "form" defined above? If it is defined as form=auth.register(), then you cannot subsequently call form.process(), as auth.register() already calls form.process().

No, you should still set session.flash in your controller code. However, your view should have {{=response.flash}}, as the framework will move the value of session.flash to response.flash after the redirect.

Also, as already noted, you cannot define form=auth() and then subsequently call form.process().

How do you suggest I arrange my controller for user?

That's up to you, but for starters, maybe instead of putting all the logic in "if" blocks, make use of the Auth callback settings, such as auth.settings.register_onaccept. And for customizing the flash messages, use the auth.messages, such as auth.messages.registration_successful.

Also, if form.process() has already been called, as in the case of the form object returned by auth(), you can check whether it has been accepted by doing:

if form.accepted:

You don't have to (and should not) call form.process() a second time.

OK so changing if form.process().accepted to if form.accepted works for user registers, if I remove it from if request.args(0)=='profile':

block, it is not triggered.

As far as flash message goes the flash works after user updates profile and everywhere else on my page but after registration it seems to hate my code and it decided to stay hidden/none :)

Thank you anyway

I do not know i it is a bug or smth but if I do not use

if form.process().accepted:

and just use

if form.accepted:

Then add_organization(form, userid) is not triggered and also if I put some prints in it I cannot see them in my PyCharm console, while, now this is interesting, e-mail is sent.

Any suggestions or ideas?

if request.args(0) == 'register':



        form = auth.register()
        if form.process().accepted:

            database = str(db).rpartition('/')[-1].replace('">', '')

            host = request.http_host
            port = request.http_port
            app = request.

application
            print database, host, app
            if host:


                name = '%s/%s' % (host, app)
            else:
                name =

 app
            userid =  form.vars.id

            email = form.vars.email
            first_name = form.vars.first_name
            last_name =form.vars.last_name
            org_name = form.vars.organization


            add_organization(form, userid)


            mail.send(to = 'someran...@domain.eu',


                      subject= 'New user registered in WoShi',
                      message = 'A new user '+ first_name + " " + last_name +' with e-mail address ' + email +" for organization " + org_name
                                + ' has registered to Woshi with url address '
                                + name + ' in database ' + database
                     )




            session.flash = T('Thank you for registering. Please check your e-mail account')
            
            redirect(URL(request.application, 'default', 'index'))
    return dict(form = form)
