[web2py:19010] appengine error
Hi all,
I'm not sure if anyone of you got this error while running on
appengine (locally, using appengine launcher).
type 'exceptions.IOError': [Errno 13] file not accessible
going through the err pg, I see this at the end.
web2py_path = os.environ.get('web2py_path', os.getcwd())
web2py_version = open(os.path.join(web2py_path, 'VERSION'),
'r').read()
Don't know how to resolve this. Any idea?
Thank you,
Joseph

[web2py:19012] Re: Writing a Book
In response to cadrentes and to elaborate on the project more...
The book will be made for people who don't have a lot of time on their
hands and would like to get their hands dirty with Web2Py as fast as
possible. Most of the book will contain links to resources and guides,
including videos, recipes, plugins, and etc. It will help you migrate
into the Web2Py community easily and understand all of the jargon used
within Web2Py (which isn't a lot).
The only thing I'd be worried about is what cadrentes said, he doesn't
know much about programming but the web2py book assumes he does. The
thing is, web2py book is about..well learning web2py not programming.
There are many other excellent resources for learning python. In
Massimo's book, it seems like he does teach a bare-bones-minimum
python programming to get you by on what you need. So cadrentes, what
were some of the things that you found troubling in the Web2Py Manual
book?
Overall, I think I'll be writing a lot of versions of the book online
and keep improving on it, and then eventually publishing it once I
feel the book has matured enough.
Thanks for all of your help guys. :)

already put together a productivity application for my position at
work. But what really helps someone like me, who has about 20 minutes
a day to study these things, are working examples and the vimeo's he
put's out. I find that applying a solution helps my understanding of
the programming concept, which comes later.
One thing I've noticed is that the programming community assumes I
know much more about programming concepts than I actually do. Having
examples with links to elaboration would be ideal.

(This isn't an April Fool's Joke)
So, I've been writing a book for Web2Py, but recently came towards a
new direction...we already have a great in-depth book writeen by
Massimo so I was wondering...
Would you guys be interested in a book for web2py like 250 pages long
that goes in-depth? Or, a nice little quick start guide :D here's the
thing, BOTH will be able to teach you the fundamentals that you'll
need to create 80%+ web applications. One will just tell you how to do
things, but then link you to the documentation page available on
web2py.com for more information.
Examples:
(QuickStart)
In order to create a table for our database, we'll need to bdefine/
b our table.
code:
db.define_table('tablename',
SQLField('fieldname','string', notnull=True)
SQLField('fieldname2','integer', notnull=True),
)
Let's say we wanted to have a table reference the tablename table.
db.define_table('table2',
SQLField('tablename_id', db.tablename),
SQLField('imafield','boolean'),
)
explain how the reference key works briefly then provide a link to
the DAL explantion page for all options
I think the quick-start guide will really help boost the web2py
community and get people started on a project. It's similar to the
Dojo, but a bit different since it'll go more in-depth than the Dojo
but at the same time you don't have to learn everything. :) It will
skip things like What is MVC? and Why Web2Py framework etc. I
believe Massimo has already full-filled that information.
The book will be available online (HTML) and PDF as well as a
published book.
Please let me know if your thoughts.

[web2py:19026] Re: DAL problem
There is a logic and these two
{{=board._extra['COUNT(mb_posts2.id)']}}
{{=board._extra[mb_posts2.id.count()]}}
should be equivalent, in fact {{=mb_posts2.id.count()}} should be
'COUNT(mb_posts2.id)'.
The rationale is that rows=db(...).select
(table.field,table.field.aggregate())
table field goes in rows[i].table.field
while aggregates are not fields so they go in rows[i]._extra
[table.field.aggregate()]

[web2py:19027] Re: using web2py for Geo / GIS stuff
Geodjango seemed pretty deeply rooted in django (in terms of the models/ORM) so my impression was it would be more of a rewrite than a port. The turbogears solution seemed more of an 'addon' which just links other GIS components like openlayers/mapfish for a more convenient use from within TG, but didn't look like a, how should I put it, web gis framework. They had ambitious plans for google summer of code regargding this. My Django and Turbogears expertise is limited though, so take all this with a grain of salt and feel free to report back if you find out something I said here does dot check out. In any case, it would be cool to have a plugin (in a sense like t2) which would be a GIS toolbox for apps utilizing Tilecache and/or Mapfish (or openlayers directly).

[web2py:19033] Input type button
Hi there, I was wondering about the button input type. I know it is recommended to use a input submit type, however, if one were wanting to use a button, how could I have web2py forward to another page with it? ie. input type=button name=register/input --- I want that to redirect to register/index.html in the VIEW. Also, I found the epydoc request class to be missing the vars method description, only get_vars is listed (which happens to be the same). However, if I replace get_vars with just vars in the address bar, it forwards me to the vars method description...its weird that it is not listed as a method. Lastly, is there a tutorial or anything about how to use CSS (classes over ids) with the various HTML tags in web2py ie. FORMS, TABLE, TR, TD, INPUT, etc. Thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups web2py Web Framework group.

[web2py:19035] MSSQL migrate error
Changing a MSSQL table definition with migrate=True in the models
produces this error ('escalated' is the original field name in my
table):
ProgrammingError: ('42S22', [42S22] [Microsoft][ODBC SQL Server
Driver][SQL Server]Invalid column name 'escalated__tmp'. (207)
(SQLExecDirectW))
I traced down the error to sql.py, class SQLTable, function _migrate
where the following batch of statements is built:
ALTER TABLE calls ADD escalated__tmp DATETIME;
UPDATE calls SET escalated__tmp=escalated;
ALTER TABLE calls DROP COLUMN escalated;
ALTER TABLE calls ADD escalated DATETIME;
UPDATE calls SET escalated=escalated__tmp;
ALTER TABLE calls DROP COLUMN escalated__tmp;
The problem is that batches in MSSQL (2005) have these rules and the
batch above breaks rule number 2:
1) CREATE DEFAULT, CREATE FUNCTION, CREATE PROCEDURE, CREATE RULE,
CREATE TRIGGER, and CREATE VIEW statements cannot be combined with
other statements in a batch. The CREATE statement must start the
batch. All other statements that follow in that batch will be
interpreted as part of the definition of the first CREATE statement.
2) A table cannot be changed and then the new columns referenced in
the same batch.
3) If an EXECUTE statement is the first statement in a batch, the
EXECUTE keyword is not required. The EXECUTE keyword is required if
the EXECUTE statement is not the first statement in the batch.
The correct batch should be (note the GO on the second line, it has to
sit on a line by itself):
ALTER TABLE calls ADD escalated__tmp DATETIME;
GO
UPDATE calls SET escalated__tmp=escalated;
ALTER TABLE calls DROP COLUMN escalated;
ALTER TABLE calls ADD escalated DATETIME;
UPDATE calls SET escalated=escalated__tmp;
ALTER TABLE calls DROP COLUMN escalated__tmp;
The fix is apparently easy but I am not sure about the implications of
the other rules so I will leave it to Massimo.
Denes.

CREATE TRIGGER, and CREATE VIEW statements cannot be combined with
other statements in a batch. The CREATE statement must start the

2) A table cannot be changed and then the new columns referenced in

3) If an EXECUTE statement is the first statement in a batch, the
EXECUTE keyword is not required. The EXECUTE keyword is required if

The correct batch should be (note the GO on the second line, it has to

GO
UPDATE calls SET escalated__tmp=escalated;

[web2py:19040] important about ajax forms
There has been a lot of discussion in the past about forms that submit
via ajax and may or may not refresh the entire page. It is also useful
to be able to break html pages into modules or plugins or
components each with its own model, view, controller in such a way
that they communicate both serversize (by sharing session and
database) and clientsize (one boxed component should be able for
example to refresh the entire page or trigger a flash).
I have prototype application that does this.
http://www.web2py.com/examples/static/web2py.app.events.tar
It uses jquery publisher subscriber mechanism. All the code is in a
new web2py_ajax and a class call jDiv (similar to Rails Partial but
more powerful in my opinion) which I could include in html.py
It allows you to write code like this:
def index():
return dict(partial1=jDiv('click me for text','mycallback1'),
partial2=jDiv('click me for flash','mycallback2'),
partial3=jDiv('click me to redirect','mycallback3'),
partial4=jDiv('click me for form','mycallback4'))
def mycallback1():
return 'hello world'
def mycallback2():
return jDiv.flash('this is a test') # flash on the container page
def mycallback3():
return jDiv.redirect('http://www.yahoo.com') # redirects entire
page
def mycallback4():
form=FORM('your name:',
INPUT(_name='name',requires=IS_NOT_EMPTY()),
INPUT(_type='submit'))
if form.accepts(request.vars):
return jDiv.flash('hello '+form.vars.name)
return form
Can you figure out what it does?
Not that the page is never reloaded. Only parts (partials, jDivs) of
the reloaded. Each jDiv lives in its own container, has one action,
can have a view, and can talk to each other.
This may require some more thought.

In MSSQL - GO runs the accumulated batch of lines (it's like enter).
The problem is, I think, that you cannot depend on the order of statement
exectution when GO executes the SQL statements - so you must complete
table alterations before you use them, and the only way to be sure of it
is to break up the execution batches.

[web2py:19042] Re: important about ajax forms
I think this is not structured _enough_.
Looking at what has already been done in this area (see jsr portlets; I do
not remember how dotnetnuke does the same with it's page components - but
that is definitely worth analyzing).
What we need is some general way that a
def index(): return something()
May be assigned to a portlet / window (say on a home page - with a read
more action), and
when read-more is selected, that same index() function may get it's own
entire page.
The point is this partials should not be knowledge within index(), rather
index should be encapsulated in something that handles this.
Keep thinking about this.

[web2py:19043] Re: important about ajax forms
another way to state this: partials are language from one very (too) narrow
use case.
The general case is that page CONTAINERS manage output, and decay to one
container per page (or the partials sort of idea that were mentioned).
Now - controller logic is just engineering logic - implementation of
solution / output;
Containers, and the protocol to connect output (URI) to a container is view
logic...
This is important, because this is how outupt to one page (for example for
PyCon) can be collected from controller outupt from 2 frameworks (django or
web2py)
And this is where this concept shows the boundaries that are appropriate
(the other end of the boundary - even if you never want to combine output
from elsewhere, the point is still that level of separation is desireable).
Come to think of it, another place to look is what do Yahoo Pipes do? That
is 3 places to look, and gather ideas: Yahoo Pipes, jsr Portlets, .Net /
what dotnetnuke uses to implement application containers...
This last piece is where web2py can start: think about how to have
portlets that can (for example) be connected to web2py application output.
I think this is more appropriate to think of as a general Python solution to
put in place

[web2py:19048] Re: Input type button
I am not sure I fully understand the question since this is not a
web2py specific questions.
If a page has a button:
button onclick={{=URL(r=request,f='sayhi')}}click me/button
when you click it will call the action sayhi(), For example
def sayhi(): return dict(message=hello)
Normally you use input inside a form.../form. The form is
submitted to the action specified in form action=.
web2py uses postbacks, i.e. It alwys submits the form to the same
action that generated the form.
Not sure I answered your question.

I am trying to just understand where web2py stores the request data,
i.e. for various inputs and for buttons, how will I tell which button/
input is being activated by the user.
I am making a simple calculator, and I want some buttons to be
type=button, not type submit. However, once they are
type=button, what does web2py use to determine what it should do.
What I am looking for here is an example like:
default/index.html
input type=button name=sayhello/input
default/result/index.html
Hello World!
How do I get the button on the default/index.html page, to call the
default/result/index.html page, and call the helloworld() function in
the controller for that page?

web2py uses postbacks. You do not have to but it makes your life much
easier. Or are you trying to submit a web2py form to a non-web2py
action?

Hi there,
I was wondering about the button input type. I know it is recommended
to use a input submit type, however, if one were wanting to use a
button, how could I have web2py forward to another page with it?
ie. input type=button name=register/input --- I want that to
redirect to register/index.html in the VIEW.
Also, I found the epydoc request class to be missing the vars method
description, only get_vars is listed (which happens to be the same).
However, if I replace get_vars with just vars in the address bar, it
forwards me to the vars method description...its weird that it is not
listed as a method.
Lastly, is there a tutorial or anything about how to use CSS (classes
over ids) with the various HTML tags in web2py ie. FORMS, TABLE, TR,
TD, INPUT, etc.
Thanks!

This is not necessary for normal controllers but perhaps it is

[web2py:19055] Re: important about ajax forms
Yarko most systems just use iframes. You can put anything you want into an iframe. The problem I am trying to solve is turning existing forms into ajax forms and do it in such a way that when the form has errors, it just modified itself without reloading the page. If the form submission succeeds the ajax response triggers an event outside the box. I do not want to use iframes because 1) I want to communicate with the outside; 2) I want to inherit the CSS of the box container. I think this is a critical ingredient although not sufficient to implement what you are suggesting. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups web2py Web Framework group.

Keeps using ajax very DRY.

There has been a lot of discussion in the past about forms that submit
via ajax and may or may not refresh the entire page. It is also useful
to be able to break html pages into modules or plugins or
components each with its own model, view, controller in such a way
that they communicate both serversize (by sharing session and
database) and clientsize (one boxed component should be able for
example to refresh the entire page or trigger a flash).
I have prototype application that does this.
http://www.web2py.com/examples/static/web2py.app.events.tar
It uses jquery publisher subscriber mechanism. All the code is in a
new web2py_ajax and a class call jDiv (similar to Rails Partial but
more powerful in my opinion) which I could include in html.py
It allows you to write code like this:
def index():
return dict(partial1=jDiv('click me for text','mycallback1'),
partial2=jDiv('click me for flash','mycallback2'),
partial3=jDiv('click me to redirect','mycallback3'),
partial4=jDiv('click me for form','mycallback4'))
def mycallback1():
return 'hello world'
def mycallback2():
return jDiv.flash('this is a test') # flash on the container page
def mycallback3():
return jDiv.redirect('http://www.yahoo.com') # redirects entire
page
def mycallback4():
form=FORM('your name:',
INPUT(_name='name',requires=IS_NOT_EMPTY()),
INPUT(_type='submit'))
if form.accepts(request.vars):
return jDiv.flash('hello '+form.vars.name)
return form
Can you figure out what it does?
Not that the page is never reloaded. Only parts (partials, jDivs) of
the reloaded. Each jDiv lives in its own container, has one action,
can have a view, and can talk to each other.
This may require some more thought.
Comments?
