Re: [web2py] Multiple forms grouped as one (django formset equivalent) with jquery plugin allowing clients to add and remove forms on the client-side

[Tom Atkins]

The SheepIt jQuery plugin looks excellent - thanks for the link.  I'll need
to make this work with web2py sometime in the next couple of months.
 Hopefully someone else (not mentioning any names ;-) ) will provide some
example code before then!

I think that app.yaml needs to become app.example.yaml (along the lines of 
routes.example.py and logging.example.conf), partly for that reason and partly 
so app.yaml doesn't get overwritten during an upgrade.

Too bad YAML doesn't support variable substitution.

That is called cascaded fields.
One example: http://groups.google.com/group/web2py/msg/b2d536d444001565

Use the advanced group search
http://groups.google.com/groups/advanced_search?safe=off&q=group:web2py
to find more entries with "cascaded"
(type the word in the form where it says "all these words:").

[web2py] Re: How to catch values from CRUD.CREATE and validate?

[DenesL]

To allow multiple room booking I would change the tables as follows:

db.define_table('room',
   Field('name','string'),
   Field('ubication','string'),
   format='%(name)s'
)

db.define_table('booking',
Field('room','list:reference room'),
Field('host','string'),
Field('approved','boolean',default=False)
)

then in validate you have to select the bookings that have approval
pending for processing.

In your index function set
db.booking.approved.writable = False
to avoid it being changed there, or even
db.booking.approved.readable = False

Also it is not clear who host can be. Another table?.
A user that is logged in?.
You can use the one included by default
and decorate booking with
@auth.requires_login()
.

[web2py] Re: Is web2py's controllers for storing strings

[pbreit]

What you are doing is fine for the most part. What you will probably see 
more often is something like this:

=== controller ==
def quotes():
quotes = ['this is quote 1', 'this is quote 2']
return dict(quotes=quotes)

=== view ===
{{for quote in quotes:}}
  {{=quote}}
{{pass}}

[web2py] Re: Is web2py's controllers for storing strings

[DenesL]

The function in the controller returns either the page content
directly as a string (no view is used) or a dictionary with the
key:value pairs to be used in the corresponding view.

Usually each function in a controller returns only a bunch of
variables, far from a gazillion.

>return dict(quote1="this is quote1", quote2="this is quote2")

In Python (and all languages I know) a function ends when it executes
a return statement, the second return is never executed, so all
variables to be returned must be inside the same return.

[web2py] Sending Email with Amazon Simple Email Service

[pbreit]

I was able to get Amazon's Simple Email Service working relatively easily 
using the "Boto" library. I tried to write up a slice but couldn't figure 
out how to format it 
properly: http://web2pyslices.com/main/slices/take_slice/123

1. Sign up for Amazon Web Services: http://aws.amazon.com

2. Enable "Simple Email Service": http://aws.amazon.com/ses/

3. Install Boto in your Web2py "site-packages" folder: 
https://github.com/boto/boto

4. Obtain your Amazon AWS-KEY and AWS-SECRET-KEY: 
https://aws-portal.amazon.com/gp/aws/developer/account/index.html?ie=UTF8&action=access-key

5. Before you get "production" access to Amazon's mail servers, you have to 
pre-register every sender and recipient email address you want to use (up to 
100). This is OK for development and testing but of course would not work in 
production. To register an email address, execute the following code, 
replacing AWS-KEY and AWS-SECRET-KEY with your own keys and 
myem...@address.com with the email address you want to register:

from boto.ses.connection import SESConnection
def verify_email_address():
conn = SESConnection('', '')
m = conn.verify_email_address('myem...@address.com')

6. Now you are ready to send an email:

from boto.ses.connection import SESConnection

aws_key = ''
aws_secret_key = ''

def send_ses(params):
conn = SESConnection(aws_key, aws_secret_key)
return conn.send_email(source='myem...@address.com',
subject='Subject',
body='Body.',
to_addresses='recipi...@email.com',
cc_addresses=None,
bcc_addresses=None,
format='text',
reply_addresses=None,
return_path=None)

[web2py] Re: Error messaging improvements

I guess so. I pretty much never see anything listed under "Variable". The 
"Inspect Attributes" are always objects which I'm not sure what to do with. 
Occasionally the Function Argument List is helpful.

Now that I see "Context", that looks like what I'd like. This may be a false 
alarm. I think I'm just really used to seeing the data.

For example, I have the stock welcome app deployed at GAE. Here's a sample curl 
request that results in a redirect:

~ $ curl -I http://jkl-web2py-welcome.appspot.com/welcome/default/user
HTTP/1.1 303 See Other
Set-Cookie: session_id_welcome="3002:826f594f-996f-4e22-9026-81b62e34ff57";

Location: /welcome/default/user/login
Date: Tue, 08 Mar 2011 22:22:38 GMT
Server: Google Frontend
Cache-Control: private, x-gzip-ok=""
Transfer-Encoding: chunked


Notice that curl doesn't follow the redirect; I think you have to use 
--location for that to happen.

Just curl -I should show you any redirects. If curl is following the redirects 
(I don't think it does by default) you can use --max-redirs 1.

-I shows the headers. -1 is a TLS option.

After you get the two forms, fetch the logout URL and see if that gives you a 
redirect to user/profile. I took a look over the code and it wasn't at all 
obvious how that would happen. Normally, the only case where you go silently to 
user/profile is when a logged-in user goes to user/register, which makes sense.

Most likely you are going to need to somehow retrieve the schema of the

you:
http://code.google.com/p/web2py/source/browse/#hg%2Fscripts

You also need to pay special attention to "id" fields:

[web2py] Is web2py's controllers for storing strings

[Jamboo]

Hello,

Based off the web2py book in the start, I was getting the idea that
the controller would store the strings versus writing them directly
into the view.  From my understanding you can do that and have a mix
in the view but what is the best practice for this?  This is what I
have started with.  I am guessing its not normal/good idea to have 1
dictionary with a gazillion strings? http://www.pastie.org/1648453
Thanks!

[web2py] Oracle DB - Select into an existing table DAL problem.

[Pivert]

Hi,

I'm giving a try to Web2Py, but I'm still unable to just get data out
of an existing table in Oracle.
As I only have a read-only account on this DB, I use a second
connection identifier called db2, and leave the db untouched.

- My first problem was a major typo in the documentation. For oracle
connector, the username and password are not separated by : but by /,
to the oracle connection string is : 
oracle://username/password@DBNameInTnsnamesFile'

- Then, when I try to list tables, I have nothing (print db2.tables).
So, I suppose I must first define them, even if they are already
defined/existing in my DB. But then, I only get error "DatabaseError:
ORA-01031: insufficient privileges", even if I use the parameter
migrate=False.

So, this code does not work :
db2.define_table('ExistingTableName', migrate=False)

How should I tell web2py about the existence of my existing Oracle
table ?? Which syntax ??

Of course, I can query it when I use the raw SQL : print
db2.executesql('..'), but I want to use the DAL.

Regards,

Those line don't get you what you want if you place them in your user function?


crud.settings.formstyle = 'table3cols' or 'table2cols' or 'divs' or 'ul'

crud.messages.submit_button = 'Submit'

Re: [web2py] Re: 1.93.2 broken update_record!

I think web2py needs regression tests, at least for core functionality

[web2py] Re: some functionality to mix html and {{python expression}} is broken since 1.92.3, even back to 1.91.6

[dlypka]

I will try to reduce it to a small example. From the call stack it
looks like web2py is confused between python code and html.  It seems
to be executing the html thinking it is python.

[pk]

ok now it works, i think this was the problem:

def user():
 loginform=auth.login()
 registerform=auth.register()
 return dict(loginform=loginform, registerform=registerform)

i changed it to just using return dict(form=auth())

[web2py] Documentation for lazy virtual fields incorrect in some cases

[Chris]

The docs for lazy virtual fields (http://web2py.com/book/default/
chapter/06#Virtual-Fields) give incorrect results; the virtual field
is incorrectly mapped to the last row selected in certain cases.

Here's a sample:

class table_story_titleAsSlug(object):
def titleAsSlug(self):
def lazy(self=self):
return urls.convert_to_slug(self.story.title)
return lazy
db.story.virtualfields.append(table_story_titleAsSlug())

titleAsSlug() will always return the value for the last row selected
from stories. While this may not apply in all cases, I've found a fix:

class table_story_titleAsSlug(object):
def titleAsSlug(self):
def lazy(title=self.story.title):
return urls.convert_to_slug(title)
return lazy
db.story.virtualfields.append(table_story_titleAsSlug())

Notes: In the debugger, the second self always refers to one instance
of table_story_titleAsSlug, which explains why self.story.title gets
overwritten. Are virtual field objects like table_story_titleAsSlug
only instantiated once?

[web2py] Error messaging improvements

[pbreit]

I saw a post on web2py-developers about error messaging. I love the 
ticketing system but one thing that always surprises me is that it never 
seems to include any of the current variables or environmental info. Would 
it make sense to add information like that or am I missing it? This is 
especially maddening with the "KeyError" errors which it seems would be 
simple to resolve if I could just see the variables.

[web2py] Re: Recommendation for web application literature

[pbreit]

It's tough, I know what you mean. While there is a lot of reference 
material, there is less about how to apply it in practice. Or at least, that 
information is scattered about in a million different blog posts.

Some great, although not free, teaching material can be found at these 
sites:
http://peepcode.com/
http://thinkvitamin.com/
http://www.lynda.com/

A friend of mine just started this educational site. If enough people 
request Web2py, I have a hunch Massimo would be willing to lead a course:

Try making the requests with curl -I and see if there's a chain of redirects

next action should be just:

but I don't understand how your change causes it

Python is clean, easy to read.

sorry I dropped a bracket abbreviating for this posting. The live code
has correct syntax and I   did a workaround to make it run. Looks like
html.py is broken in this regard. The workaround is to replace outer
ul tag by ul html helper call.

[web2py] Re: DAL tutorial video

[LightOfMooN]

Thanks for this video.
One question:
lines 97 and 100:
'name' = 'name'?

it's often need to get new info of updated record.

For example, in controller:
row = db(db.products.id==123).select().first()
row.update_record(name='helloworld')

so if I want to show new updated record with id==123 in the view, I
need one more query
row = db(db.products.id==123).select().first() again to get it updated
(or I'm missing something?)
It could be better if I can do smth like updated_row =
row.update_record(name='helloworld'), but it's impossible.
Thx

GAE serves static files directly, and I don't think they end up in the location 
that web2py expects. So the path that routes generates ends up being wrong. 
When you access /cms/static/robots.txt, GAE is fetching it for you.

You need to add something like this to your app.yaml:

- url: /favicon.ico
  static_files: applications/cms/static/favicon.ico
  upload: applications/cms/static/favicon.ico

- url: /robots.txt
  static_files: applications/cms/static/robots.txt
  upload: applications/cms/static/robots.txt

There isn't a python module for ispcp. It has fcgi though (if that
helps).

That is so cool! something like text-to-speech, but with purpose! If I
can guess, you take a script, comments get read and typed out
(displayed differently, different color maybe) while code gets
exec'ed? Or what ever you are using, its Ingenious! I was just
thinking "now that guy has to be the best typer ever!" or "how'd he
get Say to do that?" ;) Kind to have to wonder how great and so much
less painful it would be to do code reviews this way ;)

Then the next step, speech-to-text? Can almost see plugin_wiki getting
in the game! Something like Dictate or DNS, but versions that
understand and use Markmin & keywords and color codes (to mark the
difference between code & text, etc) ;)

like:

'RECORD' GREEN_USE_HEADER1 # My Title | BLUE_USE_TEXT blablablabla |
PINK_USE_CODE_PYTHON OPEN_CRAZY_QUOTE `` OPEN_WEB2PY_BRACKETS {{say
some code... CLOSE_WEB2PY_BRACKETS }} CLOSE_CRAZY_QUOTES `` |
GREEN_USE_HEADER2 ## another title | PURPLE_USE_WIDGET_SELECT, etc

I'd like to see those 2 products try to do something like that ;) LOL

Music: I agree with DenesL (i think the twins were still humming the
tune this morning) My suggestion -> Konstantin Scherbakov, maybe
Liszt's transcriptions of Beethoven symphonies for the Piano (He did
all 9, does not miss a thing and are on all fronts, perfect.) - its
the analogy: not well known, yet a master's opus! ;)

URL (f = 'default ', c = 'home')

This is desnecessary. I'm not used. Buy like this:

URL('default','home')

This is clean.

[Massimo Di Pierro]

Something like that. Actually the typing speed is random.

It is a tool I am working out, trying to automate my teaching job.

It is inspired by this:
http://code.google.com/p/playerpiano/
but not related and does more stuff.

Once I am done I will release it.

[web2py] Re: python tutorial video

[DenesL]

Sorry for the nit picking on a good overview of Python showing
important concepts, but I caught a few typos:

Line 156 (around 13:30)
  Python programmers prefer using 'self' instead of 'self'
should obviously be
  Python programmers prefer using 'self' instead of 'this'

around 18:00
190> print D(sin,x)
x is never initialized to the value of 1 mentioned in the comments
  print D(sin,1)

194> print D(lambda y: f(7,y),1)
should be
  print D(lambda y: g(7,y),1)
g being the function previously defined.

and at the very end:
233> # you can redistrubute this video freely
233> # you can redistribute this video freely

Note: I did not check the statistical functions defined around 23:00.

And, Massimo please don't use that short looped background music.

[web2py] Recommendation for web application literature

[StUStD]

What's a good, comprehensive and web2py-like literature source to
learn about web application development from the top down. I've
developed a python application, built the databases and rudimentary
web interface but I feel I'm constantly working too much from the
bottom up. E.g. session management is important, yet as a
mathematician I lack the knowledge to see things in an integrated way.
I study the web2py manual intensively, understand more and more of
it's underlying technology but feel I'm lacking the comprehensive
view. Anyone some suggestions? Thanks!

[web2py] Ubuntu 10.10 install fix

[Brian Will]

After running http://web2py.googlecode.com/hg/scripts/setup-web2py-ubuntu.sh
on ubuntu 10.10 and setting up a postgres db for an app, I was getting
"global name 'psycopg2' is not defined". Fixed it with:

apt-get install python-psycopg2
sudo /etc/init.d/apache2 restart

For 10.10, the line

apt-get -y install python2.5-psycopg2

...should read:

apt-get -y install python-psycopg2

[web2py] Re: A question from a web2py newcomer

[villas]

Does everything seem ok using the admin interface?
http://127.0.0.1:8000/admin

Try editing and running the app from there.
You should see your code correctly in db.py
The app should either run or you get a ticket or something.

I'm a bit intrigued by how the screencasts are made.
Given that they show no typos and constant typing speed, I assume you
made (or found) a system that takes a text file as input and renders it 
to a screencast automatically?

[web2py] Re: DAL new syntax RFC

[villas]

Ideally there should just be one clear and convenient way of doing
something, otherwise we can confused.

Everytime we introduce a synonym we raise numerous questions on the
list and add a paragraph to the book.  Ascribing a special meaning to
a period is totally against the clarity of the code.  I believe we
should avoid synonyms and short-cuts wherever possible.

IMO if there is a clearer and more convenient way of doing something,
we should clearly deprecate the old way and introduce and promote the
new syntax. Maybe this will make us think carefully about introducing
changes.

[web2py] advanced form question

[Manuele Pesenti]

Dear all,
I need to construct a form with some fields that has to be choosen 
within a different set depending on another fields value... is there 
some examples on line to get inspiration from?


I try to be a little more clear...

if I have a field like that:

Field('a', 'integer', requires=IS_IN_SET([1, 2, 3]))

and a second field 'b' that has to choosen in different sets, for 
examples ['a', 'b'], ['c', 'd'], ['e', 'f', 'g'], depending on the 
choosen value of the field 'a'


any idea?

Thank you

Manuele
