[web2py] Auth.register() questions

I have a couple of questions about the provided Auth.register() function (I suppose they also apply to other Auth functions in general): 1. In a controller, if I do: def register(): return dict(form=auth.register()) with the following settings in a model: auth.settings.registration_requir

[web2py] auth.user_group_role() method

This method seems to be still in trunk (http://code.google.com/p/web2py/source/browse/gluon/tools.py#2832), as I cannot find it in the latest stable. It takes a user id and return the name/role of the group that user is in. However, it doesn't seem to be able to work with custom groups. For e

[web2py] redis support in Web2py

Hi group, Could someone please let me know how much support exists for redis in web2py? I've come across this: http://code.google.com/p/web2py/source/browse/gluon/contrib/redis_cache.py, but not sure if redis is officially supported by web2py. If not, any timeline available? Many thanks.

[web2py] Default table schema for the Auth tables

Hi group, Is there anywhere I can find the default schema for the tables involved in Auth provided by Web2py, namely, 'auth_user' 'auth_group' 'auth_membership' 'auth_permission' 'auth_event' They're described in the the manual but I would like to see the exact field definitions for each of t

[web2py] Re: Default table schema for the Auth tables

I think I will just make those fields invisible for now. Defining custom auth tables seem also a little risky, as it is unclear that which fields must be kept (except for auth_user, which is used as an example in the manual) for both current and future releases. Thanks all! On Friday, April

[web2py] Design of a minimal chat-like application in Web2py

[web2py] auth.settings.create_user_groups and auth.settings.registration_requires_verification in Auth

Hi group, Two questions relating to two Auth settings: 1. when I set *auth.settings.create_user_groups = False*, I suspect that 'auth_group' table is not created at all after calling 'auth.define_tables()'. Because if I do a 'auth.add_group(...)' after 'auth.define_tables()' in a model file,

Hi Anthony, When I say 'sometimes Web2py fails to create Auth tables and other times it does', I mean running a test procedure like this: 1. if 'mydb' already exists, it is dropped from PostgreSQL server using 'dropdb mydb' 2. a fresh 'mydb' is created using 'createdb mydb' 3. then run the Web

Hi Anthony, Great insight! The removal of manual re-direction fixes the email failure! One follow-up questions: 1. The Web2py manual says that auth.settings.register_onaccept[] should be called *before* the re-direction. For my purpose here (i.e. re-directing the user to a new page after aut

[web2py] Adding permissions upon registration

[web2py] A page served by two different backends

I want to implement a page that is served by two backends, one is tornado and the other is web2py, and this concerns two questions below: 1. The tornado serves the dynamic part of the content on the page (together with some help from frontend Javascript), while the web2py handles the rest of a

By 'static content', I mean things like the layout, links, labels, buttons, input fields, tables, etc. On the other hand, values of the labels and those of the table are dynamic, such that they refreshes themselves as new values arrive via websockets. Every other pages of the app will be serve

[web2py] Re: A page served by two different backends

I see your point. Perhaps I should revise my definition of 'static' and 'dynamic': when I generate an HTML using a view of web2py, everything returned by the server will stay the same and will potentially change only after I refresh the page - this is what I mean by static. On the other hand,
