[web2py] Re: requires questions
Thanks for the suggestion. I tried it but I was unable to make use of
it. Your suggestion did force me to rethink the design so I discarded
the full IS_MATCH string(can't even remember why I went for that),
and simply kept the expression string itself (i.e. '^\\d{3}-\\d{4}-\
\d{4}-\\d{1}?$')
And now it works and looks much cleaner without eval() ...
requires=[IS_MATCH(str(db.agency[int(request.vars.issuer or
1)].regex)),CRYPT(auth.settings.hmac_key),IS_NOT_IN_DB(db,'card.id_number')]
Thanks

Not exactly a deployment solution - but TurnKey Linux (http:// www.turnkeylinux.org/) would be a good foundation for Amazon EC2.

[web2py] custom attributes
Massimo (or anyone who'd like to pitch in)
You made this suggestion when I asked a question about a help system.
Field('name',...)
db.table.name.help = 'custom attribute'
Could you please elaborate on this, and perhaps add a use case or
example?
Also, I was reading the code of register_other() of conf2py, and I found
these 2 lines that I don't quite understand:
db.auth_user.registered_by.default=auth.user.id
record=db.auth_user(request.args(0) or 0,registered_by=auth.user.id)
Why isregistered_by=auth.user.id supplied when it's already preceded
by a line that tells the database that it should use auth.user.id as the
default value. And I don't recall reading this convention of assigning
values to a record being retrieved.

[web2py] Re: How should I present the content?
Keep it simple. Start with HTML and CSS and see how far you get. Then consider layering in JavaScript and Jquery. For charting, you either need to generate the images in Web2py and server them as GF.JPG/etc or use a Javascript-based charting library (ex: http://www.reynoldsftw.com/2009/02/6-jquery-chart-plugins-reviewed/).

[web2py] Re: Can web2py support chaining response.files inside a component?
Hi Anthony,
I have to say, your proposal is logically correct. Good hint!
Furthermore, I find a more appropriate place to add those code. That
place is generic.load.
However, my complicated action index contains multi components, some
are even duplicated. Then after I deploy the new generic.load, the
index page's appearance or behavior is not 100% correct. I guess
that is caused by duplicated and/or improper location of those
component cssjs files.
Experiment abort. :-(

I see. One option might be to include code in your component.load view

if _file in response.files[:_k]:

_file0=_file.lower().split('?')[0]

script src={{=_file}} type=text/javascript/script{{

The above will link your component's css and js files in the component HTML,
which will be inserted in your 'index' page (give that you have ajax=False).
If you don't want to repeat that code in all your .load views, you can
probably create a function in a model file or module and just call the
function from your views.

Thank you Anthony for your comments and here comes my clarification.
You are right that, adding response.files within a component, has no
effect at all when called by component.load. But I still keep a copy
of those response.files inside the component, because they are needed
when visiting component.html (during developing or debugging phase).
On the other hand, when we have to copy those response.files in action
skeleton or action index, that does not feel elegant, because
action index has to explicitly include some helper resources which
not needed by itself. Imagine that, after I change implementation of
component later, I have to modify index also. Grrr.
Pbreit's suggestion is what I can do right now (thank you Pbreit too),
it is DRY, but still not solving the unnecessary coupling mentioned
above.

Does adding to response.files within a component controller work at all?
With ajax=False, it looks like LOAD creates a new environment (and
response)
to run the component controller, so I'm not sure appending to
response.files
within a component controller will affect the response.files of the
parent
controller.
response.files is only used by web2py_ajax.html, which is typically
included
in layout.html. Your index view probably extends layout.html, so
response.files added within the index controller will get included by
web2py_ajax.html. However, your component .load views probably do not
extend
layout.html, so I would guess response.files added within component
controllers would be ignored.
Haven't tried it, though, so I may be missing something.

Currently, if I add one more helper_extra.js into my fancy

[web2py] queries in Views without breaking MVC
Hi All, Let's expand little bit the example of the book. I have Persons and Dogs. A person can have several Dogs. A Dog can be connected to his owner (Person) and to the Person that it has bitten to !... In my view I'd like to show a table with one Person per row. In the first column I would have the Person name, in the second column the Person dogs and for each Dog I'd like to show also the Persons that the dog has bitten to. Of course I could retrieve the persons in the controller with db().select(db.person.ALL) and in the view I could loop it and use other queries... I don't like to do that as I do not want to break the MVC and I don't want to do DB queries from the View Another option is to build a new structure in the controller or from the view call some helper function what do you guys use in these kind of situations ? thanks -- Sebastian E.
